H PREFACE
This manual meets the emergency medical training needs of individual
soldiers. Because medical personnel will not always be readily available,
the nonmedical soldiers will have to rely heavily on their own skills and
knowledge of life-sustaining methods to survive on the integrated
battlefield. This manual also addresses first aid measures for other lifethreatening
situations. It outlines both self-treatment (self-aid) and aid to
other soldiers (buddy aid). More importantly, this manual emphasizes
prompt and effective action in sustaining life and preventing or
minimizing further suffering. First aid is the emergency care given to the
sick, injured, or wounded before being treated by medical personnel. The
Army Dictionary defines first aid as “urgent and immediate lifesaving
and other measures which can be performed for casualties by nonmedical
personnel when medical personnel are not immediately available.”
Nonmedical soldiers have received basic first aid training and should
remain skilled in the correct procedures for giving first aid. Mastery of
first aid procedures is also part of a group study training program
entitled the Combat Lifesaver (DA Pam 351-20). A combat lifesaver is a
nonmedical soldier who has been trained to provide emergency care. This
includes administering intravenous infusions to casualties as his combat
mission permits. Normally, each squad, team, or crew will have one
member who is a combat lifesaver. This manual is directed to all soldiers.
The procedures discussed apply to all types of casualties and the
measures described are for use by both male and female soldiers.
Cardiopulmonary resuscitative (CPR) procedures were deleted from this
manual. These procedures are not recognized as essential battlefield
skills that all soldiers should be able to perform. Management and
treatment of casualties on the battlefield has demonstrated that
incidence of cardiac arrest are usually secondary to other injuries
requiring immediate first aid. Other first aid procedures, such as
controlling hemorrhage are far more critical and must be performed well
to save lives. Learning and maintaining CPR skills is time and resource
intensive. CPR has very little practical application to battlefield first aid
and is not listed as a common task for soldiers. The Academy of Health
Sciences, US Army refers to the American Heart Association for the
CPR standard. If a nonmedical soldier desires to learn CPR, he may
contact his supporting medical treatment facility for the appropriate
information. All medical personnel, however, must maintain proficiency
in CPR and may be available to help soldiers master the skill. The US
Army’s official reference for CPR is FM 8-230.
This manual has been designed to provide a ready reference for the
individual soldier on first aid. Only the information necessary to support
and sustain proficiency in first aid has been boxed and the task number
has been listed. In addition, these first aid tasks for Skill Level 1 have
xv

been listed in Appendix G. The task number, title, and specific paragraph
of the appropriate information is provided in the event a cross-reference
is desired.

CHAPTER 1
FUNDAMENTAL CRITERIA FOR FIRST AID
INTRODUCTION
Soldiers may have to depend upon their first aid knowledge and skills to
save themselves or other soldiers. They may be able to save a life, prevent
permanent disability, and reduce long periods of hospitalization by
knowing what to do, what not to do, and when to seek medical assistance.
Anything soldiers can do to keep others in good fighting condition is part
of the primary mission to fight or to support the weapons system. Most
injured or ill soldiers are able to return to their units to fight and/or
support primarily because they are given appropriate and timely first aid
followed by the best medical care possible. Therefore, all soldiers must
remember the basics:
Check for BREATHING: Lack of oxygen intake
(through a compromised airway or inadequate breathing) can lead to brain
damage or death in very few minutes.
Check for BLEEDING: Life cannot continue without
an adequate volume of blood to carry oxygen to tissues.
Check for SHOCK: Unless shock is prevented or
treated, death may result even though the injury would not otherwise be
fatal.
Section I. EVALUATE CASUALTY
1-1. Casualty Evaluation (081-831-1000)
The time may come when you must instantly apply your knowledge of
lifesaving and first aid measures, possibly under combat or other adverse
conditions. Any soldier observing an unconscious and/or ill, injured, or
wounded person must carefully and skillfully evaluate him to determine
the first aid measures required to prevent further injury or death. He
should seek help from medical personnel as soon as possible, but must
NOT interrupt his evaluation or treatment of the casualty. A second
person may be sent to find medical help. One of the cardinal principles of
treating a casualty is that the initial rescuer must continue the
evaluation and treatment, as the tactical situation permits, until he is
relieved by another individual. If, during any part of the evaluation, the
casualty exhibits the conditions for which the soldier is checking, the
soldier must stop the evaluation and immediately administer first aid. In
a chemical environment, the soldier should not evaluate the casualty
1-1
•
•
•
FM 21-11
until the casualty has been masked and given the antidote. After
providing first aid, the soldier must proceed with the evaluation and
continue to monitor the casualty for further medical complications until
relieved by medical personnel. Learn the following procedures well. You
may become that soldier who will have to give first aid some day.
NOTE
Remember, when evaluating and/or treating a
casualty, you should seek medical aid as soon
as possible. DO NOT stop treatment, but if the
situation allows, send another person to find
medical aid.
WARNING
Again, remember, if there are any signs of
chemical or biological agent poisoning, you
should immediately mask the casualty. If it is
nerve agent poisoning, administer the antidote,
using the casualty’s injector/ampules. See task
081-831-1031, Administer First Aid to a Nerve
Agent Casualty (Buddy Aid).
a. Step ONE. Check the casualty for responsiveness by gently
shaking or tapping him while calmly asking, “Are you okay?” Watch for
response. If the casualty does not respond, go to step TWO. See Chapter
2, paragraph 2-5 for more information. If the casualty responds, continue
with the evaluation.
(1) If the casualty is conscious, ask him where he feels
different than usual or where it hurts. Ask him to identify the locations
of pain if he can, or to identify the area in which there is no feeling.
(2) If the casualty is conscious but is choking and cannot
talk, stop the evaluation and begin treatment. See task 081-831-1003
Clear an Object from the Throat of a Conscious Casualty. Also see
Chapter 2, paragraph 2-13 for specific details on opening the airway.
1-2
C 2, FM 21-11
WARNING
IF A BROKEN NECK OR BACK IS
SUSPECTED, DO NOT MOVE THE
CASUALTY UNLESS TO SAVE HIS LIFE.
MOVEMENT MAY CAUSE PERMANENT
PARALYSIS OR DEATH.
b. Step TWO. Check for breathing. See Chapter 2, paragraph
2-5c for procedure.
(1) If the casualty is breathing, proceed to step FOUR.
(2) If the casualty is not breathing, stop the evaluation and
begin treatment (attempt to ventilate). See task 081-831-1042, Perform
Mouth-to-Mouth Resuscitation. If an airway obstruction is apparent,
clear the airway obstruction, then ventilate.
(3) After successfully clearing the casualty’s airway,
proceed to step THREE.
c. Step THREE. Check for pulse. If pulse is present, and the
casualty is breathing, proceed to step FOUR.
(1) If pulse is present, but the casualty is still not
breathing, start rescue breathing. See Chapter 2, paragraphs 2-6, and 2-7
for specific methods.
H (2) If pulse is not found, seek medically trained personnel
for help.
d. Step FOUR. Check for bleeding. Look for spurts of blood or
blood-soaked clothes. Also check for both entry and exit wounds. If the
casualty is bleeding from an open wound, stop the evaluation and begin
first aid treatment in accordance with the following tasks, as
appropriate:
(1) Arm or leg wound–Task 081-831-1016, Put on a Field or
Pressure Dressing. See Chapter 2, paragraphs 2-15, 2-17, 2-18, and 2-19.
(2) Partial or complete amputation–Task 081-831-1017,
Put on a Tourniquet. See Chapter 2, paragraph 2-20.
(3) Open head wound–Task 081-831-1033, Apply a
Dressing to an Open Head Wound. See Chapter 3, Section I.

(2) Immobilize any casualty suspected of having a neck or
back injury by doing the following
Tell the casualty not to move.
If a back injury is suspected, place padding (rolled
or folded to conform to the shape of the arch) under the natural arch of
the casualty’s back. For example, a blanket may be used as padding.
If a neck injury is suspected, place a roll of cloth
under the casualty’s neck and put weighted boots (filled with dirt, sand
and so forth) or rocks on both sides of his head.
(3) Check the casualty’s arms and legs for open or closed
fractures.

treatment for shock, or control of bleeding and seek medical aid. See
Chapter 3, Section I for specific indications of head injury and treatment.
See task 081-831-1033, Apply a Dressing to an Open Head Wound.
1-2. Medical Assistance (081-831-1000)
When a nonmedically trained soldier comes upon an unconscious and/or
injured soldier, he must accurately evaluate the casualty to determine the
first aid measures needed to prevent further injury or death. He should seek
medical assistance as soon as possible, but he MUST NOT interrupt
treatment. To interrupt treatment may cause more harm than good to the
casualty. A second person may be sent to find medical help. If, during any
part of the evaluation, the casualty exhibits the conditions for which the
soldier is checking, the soldier must stop the evaluation and immediately
administer first aid. Remember that in a chemical environment, the soldier
should not evaluate the casualty until the casualty has been masked and
given the antidote. After performing first aid, the soldier must proceed with
the evaluation and continue to monitor the casualty for development of
conditions which may require the performance of necessary basic life saving
measures, such as clearing the airway, mouth-to-mouth resuscitation,
preventing shock, ardor bleeding control. He should continue to monitor
until relieved by medical personnel.
Section II. UNDERSTAND VITAL BODY FUNCTIONS
1-3. Respiration and Blood Circulation
Respiration (inhalation and exhalation) and blood circulation are vital
body functions. Interruption of either of these two functions need not be
fatal IF appropriate first aid measures are correctly applied.
1-7
•

•
FM 21-11
a. Respiration. When a person inhales, oxygen is taken into the
body and when he exhales, carbon dioxide is expelled from the body–this
is respiration. Respiration involves the—
Airway (nose, mouth, throat, voice box, windpipe, and
bronchial tree). The canal through which air passes to and from the lungs.
Lungs (two elastic organs made up of thousands of tiny
air spaces and covered by an airtight membrane).
Chest cage (formed by the muscle-connected ribs which
join the spine in back and the breastbone in front). The top part of the
chest cage is closed by the structure of the neck, and the bottom part is
separated from the abdominal cavity by a large dome-shaped muscle
called the diaphragm (Figure 1-1). The diaphragm and rib muscles, which
are under the control of the respiratory center in the brain, automatically
contract and relax. Contraction increases and relaxation decreases the
size of the chest cage.
When the chest cage increases and then decreases, the air pressure in the
lungs is first less and then more than the atmospheric pressure, thus
causing the air to rush in and out of the lungs to equalize the pressure.
This cycle of inhaling and exhaling is repeated about 12 to 18 times per
minute.

b. Blood Circulation. The heart and the blood vessels (arteries,
veins, and capillaries) circulate blood through the body tissues. The heart
is divided into two separate halves, each acting as a pump. The left side
pumps oxygenated blood (bright red) through the arteries into the
capillaries; nutrients and oxygen pass from the blood through the walls
of the capillaries into the cells. At the same time waste products and
carbon dioxide enter the capillaries. From the capillaries the oxygen poor
blood is carried through the veins to the right side of the heart and then
into the lungs where it expels carbon dioxide and picks up oxygen, Blood
in the veins is dark red because of its low oxygen content. Blood does not
flow through the veins in spurts as it does through the arteries.
(1) Heartbeat. The heart functions as a pump to circulate
the blood continuously through the blood vessels to all parts of the body.
It contracts, forcing the blood from its chambers; then it relaxes,
permitting its chambers to refill with blood. The rhythmical cycle of
contraction and relaxation is called the heartbeat. The normal heartbeat
is from 60 to 80 beats per minute.
(2) Pulse. The heartbeat causes a rhythmical expansion and
contraction of the arteries as it forces blood through them. This cycle of
expansion and contraction can be felt (monitored) at various body points
and is called the pulse. The common points for checking the pulse are at
the side of the neck (carotid), the groin (femoral), the wrist (radial), and
the ankle (posterial tibial).
(a) Neck (carotid) pulse. To check the neck (carotid)
pulse, feel for a pulse on the side of the casualty’s neck closest to you by
placing the tips of your first two fingers beside his Adam’s apple (Figure
1-2).
1-9
Figure 1-2. Neck (carotid) pulse.
FM 21-11
(b) Groin (femoral) pulse. To check the groin (femoral)
pulse, press the tips of two fingers into the middle of the groin (Figure
1-3).
(c) Wrist (radial) pulse. To check the wrist (radial)
pulse, place your first two fingers on the thumb side of the casualty’s
wrist (Figure 1-4).

(d) Ankle (posterial tibial) pulse. To check the ankle
(posterial tibial) pulse, place your first two fingers on the inside of the
ankle (Figure 1-5).
NOTE
DO NOT use your thumb to check a casualty’s
pulse because you may confuse your pulse beat
with that of the casualty.
1-4. Adverse Conditions
a. Lack of Oxygen. Human life cannot exist without a
continuous intake of oxygen. Lack of oxygen rapidly leads to death. First
aid involves knowing how to OPEN THE AIRWAY AND RESTORE
BREATHING AND HEARTBEAT (Chapter 2, Section I).
b. Bleeding. Human life cannot continue without an adequate
volume of blood to carry oxygen to the tissues. An important first aid
measure is to STOP THE BLEEDING to prevent loss of blood (Chapter
2, Section II).
1-11
Figure 1-5. Ankle (posterial tibi,al) pulse.
FM 21-11
c. Shock. Shock means there is inadequate blood flow to the
vital tissues and organs. Shock that remains uncorrected may result in
death even though the injury or condition causing the shock would not
otherwise be fatal. Shock can result from many causes, such as loss of
blood, loss of fluid from deep burns, pain, and reaction to the sight of a
wound or blood. First aid includes PREVENTING SHOCK, since the
casualty’s chances of survival are much greater if he does not develop
shock (Chapter 2, Section III).
d. Infection. Recovery from a severe injury or a wound depends
largely upon how well the injury or wound was initially protected.
Infections result from the multiplication and growth (spread) of germs
(bacteria: harmful microscopic organisms). Since harmful bacteria are in
the air and on the skin and clothing, some of these organisms will
immediately invade (contaminate) a break in the skin or an open wound.
The objective is to KEEP ADDITIONAL GERMS OUT OF THE
WOUND. A good working knowledge of basic first aid measures also
includes knowing how to dress the wound to avoid infection or additional
contamination (Chapters 2 and 3).
1-12
C 2, FM 21-11
CHAPTER 2
BASIC MEASURES FOR FIRST AID
INTRODUCTION
Several conditions which require immediate attention are an inadequate
airway, lack of breathing or lack of heartbeat, and excessive loss of blood.
A casualty without a clear airway or who is not breathing may die from
lack of oxygen. Excessive loss of blood may lead to shock, and shock can
lead to death; therefore, you must act immediately to control the loss of
blood. All wounds are considered to be contaminated, since infectionproducing
organisms (germs) are always present on the skin, on clothing,
and in the air. Any missile or instrument causing the wound pushes or
carries the germs into the wound. Infection results as these organisms
multiply. That a wound is contaminated does not lessen the importance
of protecting it from further contamination. You must dress and bandage
a wound as soon as possible to prevent further contamination. It is also
important that you attend to any airway, breathing, or bleeding problem
IMMEDIATELY because these problems may become life-threatening.
Section I. OPEN THE AIRWAY AND RESTORE BREATHING
H 2-1. Breathing Process
All living things must have oxygen to live. Through the breathing
process, the lungs draw oxygen from the air and put it into the blood. The
heart pumps the blood through the body to be used by the living cells
which require a constant supply of oxygen. Some cells are more
dependent on a constant supply of oxygen than others. Cells of the brain
may die within 4 to 6 minutes without oxygen. Once these cells die, they
are lost forever since they DO NOT regenerate. This could result in
permanent brain damage, paralysis, or death.
2-2. Assessment (Evaluation) Phase (081-831-1000 and 081-831-1042)
a. Check for responsiveness (Figure 2-1A)—establish whether
the casualty is conscious by gently shaking him and asking, “Are you
O.K.?”
b. Call for help (Figure 2-1B).
2-1
C 2, FM 21-11
c. Position the unconscious casualty so that he is lying on his
back and on a firm surface (Figure 2-1C) (081-831-1042).
WARNING (081-831-1042)
If the casualty is lying on his chest (prone
position), cautiously roll the casualty as a unit
so that his body does not twist (which may
further complicate a neck, back or spinal
injury).

(1) Straighten the casualty’s legs. Take the casualty’s arm
that is nearest to you and move it so that it is straight and above his
head. Repeat procedure for the other arm.
(2) Kneel beside the casualty with your knees near his
shoulders (leave space to roll his body) (Figure 2-1B). Place one hand
behind his head and neck for support. With your other hand, grasp the
casualty under his far arm (Figure 2-1C).
(3) Roll the casualty toward you using a steady and
even pull. His head and neck should stay in line with his back.
(4) Return the casualty’s arms to his sides. Straighten his
legs. Reposition yourself so that you are now kneeling at the level of the
casualty’s shoulders. However, if a neck injury is suspected, and the jawthrust
will be used, kneel at the casualty’s head, looking toward his feet.
2-3. Opening the Airway—Unconscious and Not Breathing
Casualty (081-831-1042)
H The tongue is the single most common cause of an airway obstruction
(Figure 2-2). In most cases, the airway can be cleared by simply using the
head-tilt/chin-lift technique. This action pulls the tongue away from the
air passage in the throat (Figure 2-3).

a. Step ONE (081-331-1042). Call for help and then position the
casualty. Move (roll) the casualty onto his back (Figure 2-1C above).
CAUTION
Take care in moving a casualty with a
suspected neck or back injury. Moving an
injured neck or back may permanently injure
the spine.
NOTE (081-831-1042)
If foreign material or vomitus is visible in the
mouth, it should be removed, but do not spend
an excessive amount of time doing so.
b. Step TWO (081-831-1042). Open the airway using the jawthrust

C2, FM 21-11
NOTE
The head-tilt/chin-lift is an important
procedure in opening the airway; however, use
extreme care because excess force in
performing this maneuver may cause further
spinal injury. In a casualty with a suspected
neck injury or severe head trauma, the safest
approach to opening the airway is the jawthrust
technique because in most cases it can
be accomplished without extending the neck.¹
(1) Perform the jaw-thrust technique. The jaw-thrust may
be accomplished by the rescuer grasping the angles of the casualty’s
lower jaw and lifting with both hands, one on each side, displacing the
jaw forward and up (Figure 2-4). The rescuer’s elbows should rest on the
surface on which the casualty is lying. If the lips close, the lower lip can
be retracted with the thumb. If mouth-to-mouth breathing is necessary,
close the nostrils by placing your cheek tightly against them. The head
should be carefully supported without tilting it backwards or turning it
from side to side. If this is unsuccessful, the head should be tilted back
very slightly.² The jaw-thrust is the safest first approach to opening the
airway of a casualty who has a suspected neck injury because in most
cases it can be accomplished without extending the neck.

(2) Perform the head-tilt/chin-lift technique (081-831-1042).
Place one hand on the casualty’s forehead and apply firm, backward
pressure with the palm to tilt the head back. Place the fingertips of the
other hand under the bony part of the lower jaw and lift, bringing the
chin forward. The thumb should not be used to lift the chin (Figure 2-5).
NOTE
The fingers should not press deeply into the
soft tissue under the chin because the airway
may be obstructed.
c. Step THREE. Check for breathing (while maintaining an
airway). After establishing an open airway, it is important to maintain
that airway in an open position. Often the act of just opening and
maintaining the airway will allow the casualty to breathe properly. Once
the rescuer uses one of the techniques to open the airway (jaw-thrust or
head-tilt/chin-lift), he should maintain that head position to keep the
airway open. Failure to maintain the open airway will prevent the
casualty from receiving an adequate supply of oxygen. Therefore, while
maintaining an open airway, the rescuer should check for breathing by
observing the casualty’s chest and performing the following actions
within 3 to 5 seconds:

to-mouth resuscitation.
NOTE
If the casualty resumes breathing, monitor and
maintain the open airway. If he continues to
breathe, he should be transported to a medical
treatment facility.
2-4. Rescue Breathing (Artificial Respiration)
a. If the casualty does not promptly resume adequate
spontaneous breathing after the airway is open, rescue breathing
(artificial respiration) must be started. Be calm! Think and act quickly!
The sooner you begin rescue breathing, the more likely you are to restore
the casualty’s breathing. If you are in doubt whether the casualty is
breathing, give artificial respiration, since it can do no harm to a person
who is breathing. If the casualty is breathing, you can feel and see his
chest move. Also, if the casualty is breathing, you can feel and hear air
being expelled by putting your hand or ear close to his mouth and nose.
b. There are several methods of administering rescue breathing.
The mouth-to-mouth method is preferred; however, it cannot be used in
all situations. If the casualty has a severe jaw fracture or mouth wound
or his jaws are tightly closed by spasms, use the mouth-to-nose method.
2-5. Preliminary Steps—All Rescue Breathing Methods
(081-831-1042)
a. Step ONE. Establish unresponsiveness. Call for help. Turn
or position the casualty.
b. Step TWO. Open the airway.
c. Step THREE. Check for breathing by placing your ear over
the casualty’s mouth and nose, and looking toward his chest:
2-7
FM 21-11
(1) Look for rise and fall of the casualty’s chest (Figure 2-6).
(2) Listen for sounds of breathing.
(3) Feel for breath on the side of your face. If the chest does
not rise and fall and no air is exhaled, then the casualty is breathless (not
breathing). (This evaluation procedure should take only 3 to 5 seconds.
Perform rescue breathing if the casualty is not breathing.
NOTE
Although the rescuer may notice that the
casualty is making respiratory efforts, the
airway may still be obstructed and opening the
airway may be all that is needed. If the
casualty resumes breathing, the rescuer should
continue to help maintain an open airway.
2-6. Mouth-to-Mouth Method (081-831-1042)
In this method of rescue breathing, you inflate the casualty’s lungs with
air from your lungs. This can be accomplished by blowing air into the
person’s mouth. The mouth-to-mouth rescue breathing method is
performed as follows:
a. Preliminary Steps.
2-8
Figure 2-6. Check for breathing.
C 2, FM 21-11
(1) Step ONE (081-831-1042). If the casualty is not
breathing, place your hand on his forehead, and pinch his nostrils together
with the thumb and index finger of this same hand. Let this same hand
exert pressure on his forehead to maintain the backward head-tilt and
maintain an open airway. With your other hand, keep your fingertips on
the bony part of the lower jaw near the chin and lift (Figure 2-7).
NOTE
If you suspect the casualty has a neck injury
and you are using the jaw-thrust technique,
close the nostrils by placing your cheek tightly
against them.³
(2) Step TWO (081-831-1042). Take a deep breath and
place your mouth (in an airtight seal) around the casualty’s mouth
(Figure 2-8). (If the injured person is small, cover both his nose and mouth
with your mouth, sealing your lips against the skin of his face.)

* Figure 2-7. Head-tilt/chin-lift.
C 2, FM 21-11
(3) Step THREE (081-831-1042). Blow two full breaths
into the casualty’s mouth (1 to 1 1/2 seconds per breath), taking a breath
of fresh air each time before you blow. Watch out of the corner of your eye
for the casualty’s chest to rise. If the chest rises, sufficient air is getting
into the casualty’s lungs. Therefore, proceed as described in step FOUR
below. If the chest does not rise, do the following (a, b, and c below) and
then attempt to ventilate again.
(a) Take corrective action immediately by
reestablishing the airway. Make sure that air is not leaking from around
your mouth or out of the casualty’s pinched nose.
(b) Reattempt to ventilate.
(c) If chest still does not rise, take the necessary
action to open an obstructed airway (paragraph 2-14).
NOTE
If the initial attempt to ventilate the casualty
is unsuccessful, reposition the casualty’s head
and repeat rescue breathing. Improper chin
and head positioning is the most, common
cause of difficulty with ventilation. If the
casualty cannot be ventilated after
repositioning the head, proceed with foreignbody
airway obstruction maneuvers (see Open
an Obstructed Airway, paragraph 2-14).4

C 2, FM 21-11
(4) Step FOUR (081-831-1042). After giving two breaths
which cause the chest to rise, attempt to locate a pulse on the casualty.
Feel for a pulse on the side of the casualty’s neck closest to you by
placing the first two fingers (index and middle fingers) of your hand on
the groove beside the casualty’s Adam’s apple (carotid pulse) (Figure
2-9). (Your thumb should not be used for pulse taking because you may
confuse your pulse beat with that of the casualty.) Maintain the airway
by keeping your other hand on the casualty’s forehead. Allow 5 to 10
seconds to determine if there is a pulse.
(a) If a pulse is found and the casualty is breathing
—STOP allow the casualty to breathe on his own. If possible, keep him
warm and comfortable.
(b) If a pulse is found and the casualty is not
breathing, continue rescue breathing.
(c) If a pulse is not found, seek medically trained
personnel for help.

resuscitation) is performed at the rate of about one breath every 5
seconds (12 breaths per minute) with rechecks for pulse and breathing
after every 12 breaths. Rechecks can be accomplished in 3 to 5 seconds.
See steps ONE through SEVEN (below) for specifics.
NOTE
Seek help (medical aid), if not done previously.
(1) Step ONE. If the casualty is not breathing, pinch his
nostrils together with the thumb and index finger of the hand on his
forehead and let this same hand exert pressure on the forehead to
maintain the backward head-tilt (Figure 2-7).
(2) Step TWO. Take a deep breath and place your mouth
(in an airtight seal) around the casualty’s mouth (Figure 2-8).
(3) Step THREE. Blow a quick breath into the casualty’s
mouth forcefully to cause his chest to rise. If the casualty’s chest rises,
sufficient air is getting into his lungs.
(4) Step FOUR. When the casualty’s chest rises, remove
your mouth from his mouth and listen for the return of air from his lungs
(exhalation).
(5) Step FIVE. Repeat this procedure (mouth-to-mouth
resuscitation) at a rate of one breath every 5 seconds to achieve 12
breaths per minute. Use the following count: “one, one-thousand; two,
one-thousand; three, one-thousand; four, one-thousand; BREATH; one,
one-thousand;” and so forth. To achieve a rate of one breath every 5
seconds, the breath must be given on the fifth count.
(6) Step SIX. Feel for a pulse after every 12th breath. This
check should take about 3 to 5 seconds. If a pulse beat is not found, seek
medically trained personnel for help.
(7) Step SEVEN. Continue rescue breathing until the
casualty starts to breathe on his own, until you are relieved by another
person, or until you are too tired to continue. Monitor pulse and return of
spontaneous breathing after every few minutes of rescue breathing. If
spontaneous breathing returns, monitor the casualty closely. The
casualty should then be transported to a medical treatment facility.
Maintain an open airway and be prepared to resume rescue breathing, if
necessary.

C 2, FM 21-11
2-7. Mouth-to-Nose Method
Use this method if you cannot perform mouth-to-mouth rescue breathing
because the casualty has a severe jaw fracture or mouth wound or his
jaws are tightly closed by spasms. The mouth-to-nose method is
performed in the same way as the mouth-to-mouth method except that
you blow into the nose while you hold the lips closed with one hand at the
chin. You then remove your mouth to allow the casualty to exhale
passively. It may be necessary to separate the casualty’s lips to allow the
air to escape during exhalation.
H 2-8. Heartbeat
If a casualty’s heart stops beating, you must immediately seek medically
trained personnel for help. SECONDS COUNT! Stoppage of the heart is
soon followed by cessation of respiration unless it has occurred first. Be
calm! Think and act! When a casualty’s heart has stopped, there is no
pulse at all; the person is unconscious and limp, and the pupils of his eyes
are open wide. When evaluating a casualty or when performing the
preliminary steps of rescue breathing, feel for a pulse. If you DO NOT
detect a pulse, immediately seek medically trained personnel.

2-12. Airway Obstructions
In order for oxygen from the air to flow to and from the lungs, the upper
airway must be unobstructed.
a. Upper airway obstructions often occur because—
(1) The casualty’s tongue falls back into his throat while he
is unconscious as a result of injury, cardiopulmonary arrest, and so forth.
(The tongue falls back and obstructs, it is not swallowed.)
(2) Foreign bodies become lodged in the throat. These
obstructions usually occur while eating (meat most commonly causes
obstructions). Choking on food is associated with—
Attempting to swallow large pieces of poorly
chewed food.
Drinking alcohol.
Slipping dentures.
(3) The contents of the stomach are regurgitated and may
block the airway.
(4) Blood clots may form as a result of head and facial injuries.
b. Upper airway obstructions may be prevented by taking the
following precautions:
(1) Cut food into small pieces and take care to chew slowly
and thoroughly.
(2) Avoid laughing and talking when chewing and swallowing.
(3) Restrict alcohol while eating meals.
(4) Keep food and foreign objects from children while they
walk, run, or play.
(5) Consider the correct positioning/maintenance of the
open airway for the injured or unconscious casualty.
2-21

C2, FM 21-11
c. Upper airway obstruction may cause either partial or
complete airway blockage.
H (1) Partial airway obstruction. The casualty may still have
an air exchange. A good air exchange means that the casualty can cough
forcefully, though he may be wheezing between coughs. You, the rescuer,
should not interfere, and should encourage the casualty to cough up the
object on his own. A poor air exchange may be indicated by weak
coughing with a high pitched noise between coughs. Additionally, the
casualty may show signs of shock (for example, paleness of the skin,
bluish or grayish tint around the lips or fingernail beds) indicating a need
for oxygen. You should assist the casualty and treat him as though he
had a complete obstruction.
(2) Complete airway obstruction. A complete obstruction
(no air exchange) is indicated if the casualty cannot speak, breathe, or
cough at all. He may be clutching his neck and moving erratically. In an
unconscious casualty a complete obstruction is also indicated if after
opening his airway you cannot ventilate him.
2-13. Opening the Obstructed Airway-Conscious Casualty
(081-831-1003)
Clearing a conscious casualty’s airway obstruction can be performed
with the casualty either standing or sitting, and by following a relatively
simple procedure.
WARNING
Once an obstructed airway occurs, the brain
will develop an oxygen deficiency resulting in/
unconsciousness. Death will follow rapidly if
prompt action is not taken.
a. Step ONE. Ask the casualty if he can speak or if he is
choking. Check for the universal choking sign (Figure 2-18).
2-22
FM 21-11
b. Step TWO. If the casualty can speak, encourage him to
attempt to cough; the casualty still has a good air exchange. If he is able
to speak or cough effectively, DO NOT interfere with his attempts to
expel the obstruction.
c. Step THREE. Listen for high pitched sounds when the
casualty breathes or coughs (poor air exchange). If there is poor air
exchange or no breathing, CALL for HELP and immediately deliver
manual thrusts (either an abdominal or chest thrust).
NOTE
The manual thrust with the hands centered
between the waist, and the rib cage is called an
abdominal thrust (or Heimlich maneuver). The
chest thrust (the hands are centered in the
middle of the breastbone) is used only for an
individual in the advanced stages of
pregnancy, in the markedly obese casualty, or
if there is a significant abdominal wound.
Apply ABDOMINAL THRUSTS using the procedures
below:
Stand behind the casualty and wrap your arms
around his waist.

Make a fist with one hand and grasp it with the
other. The thumb side of your fist should be against the casualty’s
abdomen, in the midline and slightly above the casualty’s navel, but well
below the tip of the breastbone (Figure 2-19).
Press the fists into the abdomen with a quick
backward and upward thrust (Figure 2-20).

o Each thrust should be a separate and distinct
movement.
H NOTE
Continue performing abdominal thrusts until
the obstruction is expelled or the casualty
becomes unconscious.
o If the casualty becomes unconscious, call for help as
you proceed with steps to open the airway and perform rescue breathing
(See task 081-831-1042, Perform Mouth-to-Mouth Resuscitation.)
• Applying CHEST THRUSTS. An alternate technique
to the abdominal thrust is the chest thrust. This technique is useful when
the casualty has an abdominal wound, when the casualty is pregnant, or
when the casualty is so large that you cannot wrap your arms around the
abdomen. TO apply chest thrusts with casualty sitting or standing:
o Stand behind the casualty and wrap your arms
around his chest with your arms under his armpits.
o Make a fist with one hand and place the thumb side
of the fist in the middle of the breastbone (take care to avoid the tip of the
breastbone and the margins of the ribs).
o Grasp the fist with the other hand and exert thrusts
Figure 2-21).
2-25
Figure 2-21. Profile view of chest thrust.
C 2, FM 21-11
o Each thrust should be delivered slowly, distinctly,
and with the intent of relieving the obstruction.
o Perform chest thrusts until the obstruction is
expelled or the casualty becomes unconscious.
o If the casualty becomes unconscious, call for help as
you proceed with steps to open the airway and perform rescue breathing.
(See task 081-831-1042, Perform Mouth-to-Mouth Resuscitation.)
2-14. Open an Obstructed Airway—Casualty Lying or
Unconscious (081-831-1042)
The following procedures are used to expel an airway obstruction in a
casualty who is lying down, who becomes unconscious, or is found
unconscious (the cause unknown):
• If a casualty who is choking becomes unconscious, call
for help, open the airway, perform a finger sweep, and attempt rescue
breathing (paragraphs 2-2 through 2-4). If you still cannot administer
rescue breathing due to an airway blockage, then remove the airway
obstruction using the procedures in steps a through e below.
• If a casualty is unconscious when you find him (the
cause unknown), assess or evaluate the situation, call for help, position
the casualty on his back, open the airway, establish breathlessness, and
attempt to perform rescue breathing (paragraphs 2-2 through 2-8).
a. Open the airway and attempt rescue breathing. (See task
081-831-1042, Perform Mouth-to-Mouth Resuscitation.)
b. If still unable to ventilate the casualty, perform 6 to 10
manual (abdominal or chest) thrusts. (Note that the abdominal thrusts
are used when casualty does not have abdominal wounds; is not pregnant
or extremely overweight.) To perform the abdominal thrusts:
(1) Kneel astride the casualty’s thighs (Figure 2-22).
2-26
FM 21-11
(2) Place the heel of one hand against the casualty’s
abdomen (in the midline slightly above the navel but well below the tip of
the breastbone). Place your other hand on top of the first one. Point your
fingers toward the casualty’s head.
(3) Press into the casualty’s abdomen with a quick, forward
and upward thrust. You can use your body weight to perform the
maneuver. Deliver each thrust slowly and distinctly.
(4) Repeat the sequence of abdominal thrusts, finger sweep,
and rescue breathing (attempt to ventilate) as long as necessary to
remove the object from the obstructed airway. See paragraph d below.
(5) If the casualty’s chest rises, proceed to feeling for pulse.
c. Apply chest thrusts. (Note that the chest thrust technique is
an alternate method that is used when the casualty has an abdominal
wound, when the casualty is so large that you cannot wrap your arms
around the abdomen, or when the casualty is pregnant.) To perform the
chest thrusts:
(1) Place the unconscious casualty on his back, face up, and
open his mouth. Kneel close to the side of the casualty’s body.
o Locate the lower edge of the casualty’s ribs with
your fingers. Run the fingers up along the rib cage to the notch (Figure
2-23A).
o Place the middle finger on the notch and the index
finger next to the middle finger on the lower edge of the breastbone. Place
2-27
Figure 2-22. Abdominal thrust on unconscious casualty.
FM 21-11
the heel of the other hand on the lower half of the breastbone next to the
two fingers (Figure 2-23B).
• Remove the fingers from the notch and place that
hand on top of the positioned hand on the breastbone, extending or
interlocking the fingers (Figure 2-23C).
• Straighten and lock your elbows with your
shoulders directly above your hands without bending the elbows,
rocking, or allowing the shoulders to sag. Apply enough pressure to
depress the breastbone 1½ to 2 inches, then release the pressure
completely (Figure 2-23D). Do this 6 to 10 times. Each thrust should be
delivered slowly and distinctly. See Figure 2-24 for another view of the
breastbone being depressed.

(2) Perform finger sweep, keep casualty face up, use tonguejaw
lift to open mouth.
• Open the casualty’s mouth by grasping both his
tongue and lower jaw between your thumb and fingers and lifting
(tongue-jaw lift) (Figure 2-25). If you are unable to open his mouth, cross
your fingers and thumb (crossed-finger method) and push his teeth apart
(Figure 2-26) by pressing your thumb against his upper teeth and
pressing your finger against his lower teeth.

Section II. STOP THE BLEEDING AND PROTECT THE WOUND
2-15. Clothing (081-831-1016)
In evaluating the casualty for location, type, and size of the wound or
injury, cut or tear his clothing and carefully expose the entire area of the
wound. This procedure is necessary to avoid further contamination,
Clothing stuck to the wound should be left in place to avoid further
injury. DO NOT touch the wound; keep it as clean as possible.
WARNING (081-831-1016)
DO NOT REMOVE protective clothing in a
chemical environment. Apply dressings over
the protective clothing.

FM 21-11
2-16. Entrance and Exit Wounds
Before applying the dressing, carefully examine the casualty to
determine if there is more than one wound. A missile may have entered at
one point and exited at another point. The EXIT wound is usually
LARGER than the entrance wound.
WARNING
Casualty should be continually monitored for
development of conditions which may require
the performance of necessary basic lifesaving
measures, such as clearing the airway and
mouth-to-mouth resuscitation. All open (or
penetrating) wounds should be checked for a
point of entry and exit and treated
accordingly.
WARNING
If the missile lodges in the body (fails to exit),
DO NOT attempt to remove it or probe the
wound. Apply a dressing. If there is an object
extending from (impaled in) the wound, DO
NOT remove the object. Apply a dressing
around the object and use additional
improvised bulky materials dressings (use the
cleanest material available) to build up the area
around the object. Apply a supporting
bandage over the bulky materials to hold them
in place.
2-17. Field Dressing (081-831-1016)
a. Use the casualty’s field dressing; remove it from the wrapper
and grasp the tails of the dressing with both hands (Figure 2-28).
2-32
FM 21-11
WARNING
DO NOT touch the white (sterile) side of the
dressing, and DO NOT allow the white (sterile)
side of the dressing to come in contact with
any surface other than the wound.
b. Hold the dressing directly over the wound with the white side
down. Pull the dressing open (Figure 2-29) and place it directly over the
wound (Figure 2-30).
2-33
Figure 2-28. Grasping tails of dressing with both hands.

FM 21-11
c. Hold the dressing in place with one hand. Use the other hand
to wrap one of the tails around the injured part, covering about one-half
of the dressing (Figure 2-31). Leave enough of the tail for a knot. If the
casualty is able, he may assist by holding the dressing in place.
d. Wrap the other tail in the opposite direction until the
remainder of the dressing is covered. The tails should seal the sides of the
dressing to keep foreign material from getting under it.
2-34

I I
FM 21-11
e. Tie the tails into a nonslip knot over the outer edge of the
dressing (Figure 2-32). DO NOT TIE THE KNOT OVER THE WOUND.
In order to allow blood to flow to the rest of an injured limb, tie the
dressing firmly enough to prevent it from slipping but without causing a
tourniquet-like effect; that is, the skin beyond the injury becomes cool,
blue, or numb.
2-18. Manual Pressure (081-831-1016)
a. If bleeding continues after applying the sterile field dressing,
direct manual pressure may be used to help control bleeding. Apply such
pressure by placing a hand on the dressing and exerting firm pressure for
5 to 10 minutes (Figure 2-33). The casualty may be asked to do this
himself if he is conscious and can follow instructions.
2-35
Figure 2-32. Tails tied into nonslip knot.
Figure 2-33. Direct manual pressure applied.
FM 21-11
b. Elevate an injured limb slightly above the level of the heart
to reduce the bleeding (Figure 2-34).
WARNING
DO NOT elevate a suspected fractured limb
unless it has been properly splinted. (To splint
a fracture before elevating, see task
081-831-1034, Splint a Suspected Fracture.)
c. If the bleeding stops, check and treat for shock. If the
bleeding continues, apply a pressure dressing.
2-19. Pressure Dressing (081-831-1016)
Pressure dressings aid in blood clotting and compress the open blood
vessel. If bleeding continues after the application of a field dressing,
manual pressure, and elevation, then a pressure dressing must be applied
as follows:
a. Place a wad of padding on top of the field dressing, directly
over the wound (Figure 2-35). Keep injured extremity elevated.
2-36
Figure 2-34. Injured limb elevated.
C2, FM 21-11
NOTE
Improvised bandages may be made from strips
of cloth. These strips may be made from
T-shirts, socks, or other garments.
b. Place an improvised dressing (or cravat, if available) over the
wad of padding (Figure 2-36). Wrap the ends tightly around the injured
limb, covering the previously placed field dressing (Figure 2-37).
2-37

C 2, FM 21-11
c. Tie the ends together in a nonslip knot, directly over the
wound site (Figure 2-38). DO NOT tie so tightly that it has a tourniquetlike
effect. If bleeding continues and all other measures have failed, or if
the limb is severed, then apply a tourniquet. Use the tourniquet as a
LAST RESORT. When the bleeding stops, check and treat for shock.
NOTE
Wounded extremities should be checked
periodically for adequate circulation. The
dressing must be loosened if the extremity
becomes cool, blue or gray, or numb.
2-38

C 2, FM 21-11
H NOTE
If bleeding continues and all other measures
have failed (dressing and covering wound,
applying direct manual pressure, elevating
limb above heart level, and applying pressure
dressing maintaining limb elevation), then
apply digital pressure. See Appendix E for
appropriate pressure points.
2-20. Tourniquet (081-831-1017)
A tourniquet is a constricting band placed around an arm or leg to
control bleeding. A soldier whose arm or leg has been completely
amputated may not be bleeding when first discovered, but a tourniquet
should be applied anyway. This absence of bleeding is due to the body’s
normal defenses (contraction of blood vessels) as a result of the
amputation, but after a period of time bleeding will start as the blood
vessels relax. Bleeding from a major artery of the thigh, lower leg, or arm
and bleeding from multiple arteries (which occurs in a traumatic
amputation) may prove to be beyond control by manual pressure. If the
pressure dressing under firm hand pressure becomes soaked with blood
and the wound continues to bleed, apply a tourniquet.
WARNING
Casualty should be continually monitored for
development of conditions which may require
the performance of necessary basic life-saving
measures, such as: clearing the airway,
performing mouth-to-mouth resuscitation,
preventing shock, and/or bleeding control. All
open (or penetrating) wounds should be
checked for a point of entry or exit and treated
accordingly.
H The tourniquet should not be used unless a pressure dressing has failed to
stop the bleeding or an arm or leg has been cut off. On occasion,
tourniquets have injured blood vessels and nerves. If left in place too
long, a tourniquet can cause loss of an arm or leg. Once applied, it must
stay in place, and the casualty must be taken to the nearest medical
treatment facility as soon as possible. DO NOT loosen or release a
tourniquet after it has been applied and the bleeding has stopped.

a. Improvising a Tourniquet (081-831-1017). In the absence of a
specially designed tourniquet, a tourniquet may be made from a strong,
pliable material, such as gauze or muslin bandages, clothing, or kerchiefs.
An improvised tourniquet is used with a rigid stick-like object. To
minimize skin damage, ensure that the improvised tourniquet is at least 2
inches wide.
WARNING
The tourniquet must be easily identified or
easily seen.
WARNING
DO NOT use wire or shoestring for a
tourniquet band.
WARNING
A tourniquet is only used on arm(s) or leg(s)
where there is danger of loss of casualty’s life.
b. Placing the Improvised Tourniquet (081-831-1017).
(1) Place the tourniquet around the limb, between the
wound and the body trunk (or between the wound and the heart). Place
the tourniquet 2 to 4 inches from the edge of the wound site (Figure 2-39).
Never place it directly over a wound or fracture or directly on a joint
(wrist, elbow, or knee). For wounds just below a joint, place the
tourniquet just above and as close to the joint as possible.
2-40
Figure 2-39. Tourniquet 2 to 4 inches above wound.
FM 21-11
(2) The tourniquet should have padding underneath. If
possible, place the tourniquet over the smoothed sleeve or trouser leg to
prevent the skin from being pinched or twisted. If the tourniquet is long
enough, wrap it around the limb several times, keeping the material as
flat as possible. Damaging the skin may deprive the surgeon of skin
required to cover an amputation. Protection of the skin also reduces pain.
c. Applying the Tourniquet (081-831-1017).
(1) Tie a half-knot. (A half-knot is the same as the first part
of tying a shoe lace.)
(2) Place a stick (or similar rigid object) on top of the halfknot
(Figure 2-40).
(3) Tie a full knot over the stick (Figure 2-41).

FM 21-11
(4) Twist the stick (Figure 2-42) until the tourniquet is tight
around the limb and/or the bright red bleeding has stopped. In the case of
amputation, dark oozing blood may continue for a short time. This is the
blood trapped in the area between the wound and tourniquet.
(5) Fasten the tourniquet to the limb by looping the free
ends of the tourniquet over the ends of the stick. Then bring the ends
around the limb to prevent the stick from loosening. Tie them together
under the limb (Figure 2-43A and B).

FM 21-11
NOTE (081-831-1017)
Other methods of securing the stick may be
used as long as the stick does not unwind and
no further injury results.
NOTE
If possible, save and transport any severed
(amputated) limbs or body parts with (but out
of sight of) the casualty.
(6) DO NOT cover the tourniquet–you should leave it in
full view. If the limb is missing (total amputation), apply a dressing to
the stump.
(7) Mark the casualty’s forehead, if possible, with a “T” to
indicate a tourniquet has been applied. If necessary, use the casualty’s
blood to make this mark.
(8) Check and treat for shock.
(9) Seek medical aid.
CAUTION (081-831-1017)
DO NOT LOOSEN OR RELEASE THE
TOURNIQUET ONCE IT HAS BEEN
APPLIED BECAUSE IT COULD ENHANCE
THE PROBABILITY OF SHOCK.

Section III. CHECK AND TREAT FOR SHOCK
2-21. Causes and Effects
a. Shock may be caused by severe or minor trauma to the body.
It usually is the result of—
Significant loss of blood.
Heart failure.
Dehydration.
Severe and painful blows to the body.
Severe burns of the body.
Severe wound infections.
Severe allergic reactions to drugs, foods, insect stings,
and snakebites.
b. Shock stuns and weakens the body. When the normal blood
flow in the body is upset, death can result. Early identification and
proper treatment may save the casualty’s life.
c. See FM 8-230 for further information and details on specific
types of shock and treatment.
2-22. Signs/Symptoms (081-831-1000)
Examine the casualty to see if he has any of the following
signs/symptoms:
Sweaty but cool skin (clammy skin).
Paleness of skin.
Restlessness, nervousness.
Thirst.
Loss of blood (bleeding).
Confusion (or loss of awareness).

Nausea and/or vomiting.
2-23. Treatment/Prevention (081-831-1005)
In the field, the .procedures to treat shock are identical to .procedures that
would be performed to prevent shock. When treating a casualty, assume
that shock is present or will occur shortly. By waiting until actual
signs/symptoms of shock are noticeable, the rescuer may jeopardize the
casualty’s life.
a. Position the Casualty. (DO NOT move the casualty or his
limbs if suspected fractures have not been splinted. See Chapter 4 for
details.)
(1) Move the casualty to cover, if cover is available and the
situation permits.
(2) Lay the casualty on his back.
NOTE
A casualty in shock after suffering a heart
attack, chest wound, or breathing difficulty,
may breathe easier in a sitting position. If this
is the case, allow him to sit upright, but
monitor carefully in case his condition
worsens.
(3) Elevate the casualty’s feet higher than the level of his
heart. Use a stable object (a box, field pack, or rolled up clothing) so that
his feet will not slip off (Figure 2-44).
WARNING
DO NOT elevate legs if the casualty has an
unsplinted broken leg, head injury, or
abdominal injury. (See task 081-831-1034,
Splint a Suspected Fracture, and task
081-831-1025, Apply a Dressing to an Open
Abdominal Wound.)
2-45
•
•
•
FM 21-11
WARNING (081-831-1005)
Check casualty for leg fracture(s) and splint, if
necessary, before elevating his feet. For a
casualty with an abdominal wound, place
knees in an upright (flexed) position.
(4) Loosen clothing at the neck, waist, or wherever it may
be binding.
CAUTION (081-831-1005)
DO NOT LOOSEN OR REMOVE protective
clothing in a chemical environment.
(5) Prevent chilling or overheating. The key is to maintain
body temperature. In cold weather, place a blanket or other like item over
him to keep him warm and under him to prevent chilling (Figure 2-45).
However, if a tourniquet has been applied, leave it exposed (if possible).
In hot weather, place the casualty in the shade and avoid excessive
covering.
2-46
Figure 2-44. Clothing loosened and feet elevated.
Figure 2-45. Body temperature maintained.
FM 21-11
(6) Calm the casualty. Throughout the entire procedure of
treating and caring for a casualty, the rescuer should reassure the
casualty and keep him calm. This can be done by being authoritative
(taking charge) and by showing self-confidence. Assure the casualty that
you are there to help him.
(7) Seek medical aid.
b. Food and/or Drink. During the treatment/prevention of
shock, DO NOT give the casualty any food or drink. If you must leave the
casualty or if he is unconscious, turn his head to the side to prevent him
from choking should he vomit (Figure 2-46).
c. Evaluate Casualty. If necessary, continue with the casualty’s
evaluation.

CHAPTER 3
FIRST AID FOR SPECIAL WOUNDS
INTRODUCTION
H Basic lifesaving steps are discussed in Chapters 1 and 2: clear the
airway/restore breathing, stop the bleeding, protect the wound, and
treat/prevent shock. They apply to first aid measures for all injuries.
Certain types of wounds and burns will require special precautions and
procedures when applying these measures. This chapter discusses first
aid procedures for special wounds of the head, face, and neck; chest and
stomach wounds; and burns. It also discusses the techniques for applying
dressings and bandages to specific parts of the body.
Section I. GIVE PROPER FIRST AID FOR HEAD INJURIES
3-1. Head Injuries
A head injury may consist of one or a combination of the following
conditions: a concussion, a cut or bruise of the scalp, or a fracture of the
skull with injury to the brain and the blood vessels of the scalp. The
damage can range from a minor cut on the scalp to a severe brain injury
which rapidly causes death. Most head injuries lie somewhere between
the two extremes. Usually, serious skull fractures and brain injuries
occur together; however, it is possible to receive a serious brain injury
without a skull fracture. The brain is a very delicate organ; when it is
injured, the casualty may vomit, become sleepy, suffer paralysis, or lose
consciousness and slip into a coma. All severe head injuries are
potentially life-threatening. For recovery and return to normal function,
casualties require proper first aid as a vital first step.
3-2. Signs/Symptoms (081-831-1000)
A head injury may be open or closed. In open injuries, there is a visible
wound and, at times, the brain may actually be seen. In closed injuries,
no visible injury is seen, but the casualty may experience the same signs
and symptoms. Either closed or open head injuries can be life-threatening
if the injury has been severe enough; thus, if you suspect a head injury,
evaluate the casualty for the following:
Current or recent unconsciousness (loss of consciousness).
Nausea or vomiting.
3-1
I: I
C 2, FM 21-11
Convulsions or twitches (involuntary jerking and shaking).
Slurred speech.
Confusion.
Sleepiness (drowsiness).
Loss of memory (does casualty know his own name,
where he is, and so forth).
Clear or bloody fluid leaking from nose or ears.
Staggering in walking.
Dizziness.
A change in pulse rate.
Breathing problems.
Eye (vision) problems, such as unequal pupils.
Paralysis.
Headache.
Black eyes.
Bleeding from scalp/head area.
Deformity of the head.
3-3. General First Aid Measures (081-831-1000)
a. General Considerations. The casualty with a head injury (or
suspected head injury) should be continually monitored for the
development of conditions which may require the performance of the
necessary basic lifesaving measures, therefore be prepared to—
Clear the airway (and be prepared to perform the basic
lifesaving measures).
Treat as a suspected neck/spinal injury until proven
otherwise. (See Chapter 4 for more information.)

FM 21-11
Place a dressing over the wounded area. DO NOT
attempt to clean the wound.
Seek medical aid.
Keep the casualty warm.
DO NOT attempt to remove a protruding object from the
head.
DO NOT give the casualty anything to eat or drink.
b. Care of the Unconscious Casualty. If a casualty is
unconscious as the result of a head injury, he is not able to defend
himself. He may lose his sensitivity to pain or ability to cough up blood
or mucus that may be plugging his airway. An unconscious casualty
must be evaluated for breathing difficulties, uncontrollable bleeding, and
spinal injury.
(1) Breathing. The brain requires a constant supply of
oxygen. A bluish (or in an individual with dark skin—grayish) color of
skin around the lips and nail beds indicates that the casualty is not
receiving enough air (oxygen). Immediate action must be taken to clear
the airway, to position the casualty on his side, or to give artificial
respiration. Be prepared to give artificial respiration if breathing should
stop.
(2) Bleeding. Bleeding from a head injury usually comes
from blood vessels within the scalp. Bleeding can also develop inside the
skull or within the brain. In most instances bleeding from the head can be
controlled by proper application of the field first aid dressing.
CAUTION (081-831-1033)
DO NOT attempt to put unnecessary pressure
on the wound or attempt to push any/brain
matter back into the head (skull). DO NOT
apply a pressure dressing.
(3) Spinal injury. A person that has an injury above the
collar bone or a head injury resulting in an unconscious state should be
suspected of having a neck or head injury with spinal cord damage.
Spinal cord injury may be indicated by a lack of responses to stimuli,
stomach distention (enlargement), or penile erection.
3-3
•
•
•
•
•
FM 21-11
(a) Lack of responses to stimuli. Starting with the
feet, use a sharp pointed object–a sharp stick or something similar, and
prick the casualty lightly while observing his face. If the casualty blinks
or frowns, this indicates that he has feeling and may not have an injury to
the spinal cord. If you observe no response in the casualty’s reflexes after
pricking upwards toward the chest region, you must use extreme caution
and treat the casualty for an injured spinal cord.
(b) Stomach distention (enlargement). Observe the
casualty’s chest and stomach. If the stomach is distended (enlarged)
when the casualty takes a breath and the chest moves slightly, the
casualty may have a spinal injury and must be treated accordingly.
(c) Penile erection. A male casualty may have a penile
erection, an indication of a spinal injury.
CAUTION
Remember to suspect any casualty who has a
severe head injury or who is/unconscious as
possibly having a broken neck or a spinal cord
injury! It is better to treat conservatively and
assume that the neck/spinal cord is injured
rather than to chance further injuring the
casualty. Consider this when you position the
casualty. See Chapter 4, paragraph 4-9 for
treatment procedures of spinal column
injuries.
c. Concussion. If an individual receives a heavy blow to the
head or face, he may suffer a brain concussion, which is an injury to the
brain that involves a temporary loss of some or all of the brain’s ability to
function. For example, the casualty may not breathe properly for a short
period of time, or he may become confused and stagger when he attempts
to walk. A concussion may only last for a short period of time. However,
if a casualty is suspected of having suffered a concussion, he must be
seen by a physician as soon as conditions permit.
d. Convulsions. Convulsions (seizures/involuntary jerking) may
occur after a mild head injury. When a casualty is convulsing, protect
him from hurting himself. Take the following measures:
(1) Ease him to the ground.
(2) Support his head and neck.
3-4
C 2, FM 21-11
(3) Maintain his airway.
(4) Call for assistance.
(5) Treat the casualty’s wounds and evacuate him
immediately.
e. Brain Damage. In severe head injuries where brain tissue is
protruding, leave the wound alone; carefully place a first aid dressing
over the tissue. DO NOT remove or disturb any foreign matter that may
be in the wound. Position the casualty so that his head is higher than his
body. Keep him warm and seek medical aid immediately.
NOTE
DO NOT forcefully hold the arms and legs if
they are jerking because this can lead to
broken bones.
DO NOT force anything between the
casualty’s teeth-especially if they are tightly
clenched because this may obstruct the
casualty’s airway.
Maintain the casualty’s airway if necessary.
3-4. Dressings and Bandages (081-831-1000 and 081-831-1033)
H a. Evaluate the Casualty (081-831-1000). Be prepared to perform
lifesaving measures. The basic lifesaving measures may include clearing
the airway, rescue breathing, treatment for shock, and/or bleeding
control.
b. Check Level of Consciousness/Responsiveness (081-831-1033).
With a head injury, an important area to evaluate is the casualty’s level
of consciousness and responsiveness. Ask the casualty questions such
as—
“What is your name?” (Person)
“Where are you?” (Place)
“What day/month/year is it?” (Time)
3-5

C 2, FM 21-11
Any incorrect responses, inability to answer, or changes in responses
should be reported to medical personnel. Check the casualty’s level of
consciousness every 15 minutes and note any changes from earlier
observations.
c. Position the Casualty (081-831-1033).
WARNING (081-831-1033)
DO NOT move the casualty if you suspect he
has sustained a neck, spine, or severe, head
injury (which produces any signs or symptoms
other than minor bleeding). See task
081-831-1000, Evaluate the Casualty.
If the casualty is conscious or has a minor (superficial)
scalp wound:
o Have the casualty sit up (unless other injuries
prohibit or he is unable); OR
o If the casualty is lying down and is not accumulating
fluids or drainage in his throat, elevate his head slightly; OR
o If the casualty is bleeding from or into his mouth or
throat, turn his head to the side or position him on his side so that the
airway will be clear. Avoid pressure on the wound or place him on his side
–opposite the site of the injury (Figure 3-1).
If the casualty is unconscious or has a severe head
injury, then suspect and treat him as having a potential neck or spinal
injury, immobilize and DO NOT move the casualty.

(3) Tie the ends over the dressing (Figure 3-11 C).
Section II. GIVE PROPER FIRST AID FOR
FACE AND NECK INJURIES
3-5. Face Injuries
Soft tissue injuries of the face and scalp are common. Abrasions (scrapes)
of the skin cause no serious problems. Contusions (injury without a break
in the skin) usually cause swelling. A contusion of the scalp looks and
feels like a lump. Laceration (cut) and avulsion (torn away tissue) injuries
are also common. Avulsions are frequently caused when a sharp blow

©
Figure 3-11. Cravat bandage applied to head (Illustrated A thru C).
C 2, FM 21-11
separates the scalp from the skull beneath it. Because the face and scalp
are richly supplied with blood vessels (arteries and veins), wounds of
these areas usually bleed heavily.
3-6. Neck Injuries
Neck injuries may result in heavy bleeding. Apply manual pressure
above and below the injury and attempt to control the bleeding. Apply a
dressing. Always evaluate the casualty for a possible neck fracture/spinal
cord injury; if suspected, seek medical treatment immediately.
H NOTE
Establish and maintain the airway in cases of
facial or neck injuries. If a neck fracture or/
spinal cord injury is suspected, immobilize or
stabilize casualty. See Chapter 4 for further
information on treatment of spinal injuries.
3-7. Procedure
When a casualty has a face or neck injury, perform the measures below.
a. Step ONE. Clear the airway. Be prepared to perform any of
the basic lifesaving steps. Clear the casualty’s airway (mouth) with your
fingers, remove any blood, mucus, pieces of broken teeth or bone, or bits
of flesh, as well as any dentures.
b. Step TWO. Control any bleeding, especially bleeding that
obstructs the airway. Do this by applying direct pressure over a first aid
dressing or by applying pressure at specific pressure points on the face,
scalp, or temple. (See Appendix E for further information on pressure
points.) If the casualty is bleeding from the mouth, position him as
indicated (c below) and apply manual pressure.
CAUTION
Take care not to apply too much pressure to
the scalp if a skull fracture is suspected.
c. Step THREE. Position the casualty. If the casualty is
bleeding from the mouth (or has other drainage, such as mucus, vomitus,
3-14
FM 21-11
or so forth) and is conscious, place him in a comfortable sitting position
and have him lean forward with his head tilted slightly down to permit
free drainage (Figure 3-12). DO NOT use the sitting position if–
It would be harmful to the casualty because of other
injuries.
The casualty is unconscious, in which case, place him on
his side (Figure 3-13). If there is a suspected injury to the neck or spine,
immobilize the head before turning the casualty on his side.
CAUTION
If you suspect the casualty has a neck/spinal
injury, then immobilize his head/neck and treat
him as outlined in Chapter 4.

d. Step FOUR. Perform other measures.
(1) Apply dressings/bandages to specific areas of the face.
(2) Check for missing teeth and pieces of tissue. Check for
detached teeth in the airway. Place detached teeth, pieces of ear or nose
on a field dressing and send them along with the casualty to the medical
facility. Detached teeth should be kept damp.
(3) Treat for shock and seek medical treatment
IMMEDIATELY.
3-8. Dressings and Bandages (081-831-1033)
a. Eye Injuries. The eye is a vital sensory organ, and blindness
is a severe physical handicap. Timely first aid of the eye not only relieves
pain but also helps prevent shock, permanent eye injury, and possible loss of
vision. Because the eye is very sensitive, any injury can be easily aggravated
if it is improperly handled. Injuries of the eye may be quite severe. Cuts of
the eyelids can appear to be very serious, but if the eyeball is not involved, a
person’s vision usually will not be damaged. However, lacerations (cuts) of
the eyeball can cause permanent damage or loss of sight.
(1) Lacerated/torn eyelids. Lacerated eyelids may bleed
heavily, but bleeding usually stops quickly. Cover the injured eye with a
sterile dressing. DO NOT put pressure on the wound because you may
injure the eyeball. Handle torn eyelids very carefully to prevent further
injury. Place any detached pieces of the eyelid on a clean bandage or
dressing and immediately send them with the casualty to the medical
facility.
(2) Lacerated eyeball (injury to the globe). Lacerations or
cuts to the eyeball may cause serious and permanent eye damage. Cover
the injury with a loose sterile dressing. DO NOT put pressure on the
eyeball because additional damage may occur. An important point to
remember is that when one eyeball is injured, you should immobilize both
eyes. This is done by applying a bandage to both eyes. Because the eyes
move together, covering both will lessen the chances of further damage to
the injured eye.
CAUTION
DO NOT apply pressure when there is a
possible laceration of the eyeball. The eyeball
contains fluid. Pressure applied over the eye
will force the fluid out, resulting in/permanent
injury. APPLY PROTECTIVE DRESSING
WITHOUT ADDED PRESSURE.
3-16
FM 21-11
(3) Extruded eyeballs. Soldiers may encounter casualties
with severe eye injuries that include an extruded eyeball (eyeball out-ofsocket).
In such instances you should gently cover the extruded eye with
a loose moistened dressing and also cover the unaffected eye. DO NOT
bind or exert pressure on the injured eye while applying a loose dressing.
Keep the casualty quiet, place him on his back, treat for shock (make
warm and comfortable), and evacuate him immediately.
(4) Burns of the eyes. Chemical burns, thermal (heat) burns,
and light burns can affect the eyes.
(a) Chemical burns. Injuries from chemical burns
require immediate first aid. Chemical burns are caused mainly by acids or
alkalies. The first aid is to flush the eye(s) immediately with large
amounts of water for at least 5 to 20 minutes, or as long as necessary to
flush out the chemical. If the burn is an acid burn, you should flush the
eye for at least 5 to 10 minutes. If the burn is an alkali burn, you should
flush the eye for at least 20 minutes. After the eye has been flushed,
apply a bandage over the eyes and evacuate the casualty immediately.
(b) Thermal burns. When an individual suffers burns
of the face from a fire, the eyes will close quickly due to extreme heat.
This reaction is a natural reflex to protect the eyeballs; however, the
eyelids remain exposed and are frequently burned. If a casualty receives
burns of the eyelids/face, DO NOT apply a dressing; DO NOT TOUCH;
seek medical treatment immediately.
(c) Light burns. Exposure to intense light can burn an
individual. Infrared rays, eclipse light (if the casualty has looked directly
at the sun), or laser burns cause injuries of the exposed eyeball.
Ultraviolet rays from arc welding can cause a superficial burn to the
surface of the eye. These injuries are generally not painful but may cause
permanent damage to the eyes. Immediate first aid is usually not
required. Loosely bandaging the eyes may make the casualty more
comfortable and protect his eyes from further injury caused by exposure
to other bright lights or sunlight.
CAUTION
In certain instances both eyes are usually
bandaged; but, in hazardous surroundings
leave the uninjured eye uncovered so that the
casualty may be able to see.

b. Side-of-Head or Cheek Wound (081-831-1033).
Facial injuries to the side of the head or the cheek may bleed profusely
(Figure 3-14). Prompt action is necessary to ensure that the airway
remains open and also to control the bleeding. It may be necessary to
apply a dressing. To apply a dressing—
(1) Remove the dressing from its wrapper.
(2) Grasp the tails in both hands.
(3) Hold the dressing directly over the wound with the
white side down and place it directly on the wound (Figure 3-15 A).
(4) Hold the dressing in place with one hand (the casualty
may assist if able). Wrap the top tail over the top of the head and bring it
down in front of the ear (on the side opposite the wound), under the chin
(Figure 3-15 B ) and up over the dressing to a point just above the ear (on
the wound side).

(6) Cross the two tails (on the wound side) (Figure 3-17) and
bring one end across the forehead (above the eyebrows) to a point just in
front of the opposite ear (on the uninjured side).
(7) Wrap the other tail around the back of the head (at the
base of the skull), and tie the two ends just in front of the ear on the
uninjured side with a nonslip knot (Figure 3-18).
c. Ear Injuries. Lacerated (cut) or avulsed (torn) ear tissue may
not, in itself, be a serious injury. Bleeding, or the drainage of fluids from
the ear canal, however, may be a sign of a head injury, such as a skull
fracture. DO NOT attempt to stop the flow from the inner ear canal nor

put anything into the ear canal to block it. Instead, you should cover the
ear lightly with a dressing. For minor cuts or wounds to the external ear,
apply a cravat bandage as follows:
(1) Place the middle of the bandage over the ear (Figure
3-19 A).
(2) Cross the ends, wrap them in opposite directions around
the head, and tie them (Figures 3-19 B and 3-19 C).
(3) If possible, place some dressing material between the
back of the ear and the side of the head to avoid crushing the ear against
the head with the bandage.
d. Nose Injuries. Nose injuries generally produce bleeding. The
bleeding may be controlled by placing an ice pack over the nose, or
pinching the nostrils together. The bleeding may also be controlled by
placing torn gauze (rolled) between the upper teeth and the lip.
CAUTION
DO NOT attempt to remove objects inhaled in
the nose. An untrained person who/removes
such an object could worsen the casualty’s
condition and cause permanent/injury.

FM 21-11
e. Jaw Injuries. Before applying a bandage to a casualty’s jaw,
remove all foreign material from the casualty’s mouth. If the casualty is
unconscious, check for obstructions in the airway. When applying the
bandage, allow the jaw enough freedom to permit passage of air and
drainage from the mouth.
(1) Apply bandages attached to field first aid dressing to
the jaw. After dressing the wound, apply the bandages using the same
technique illustrated in Figures 3-5 through 3-8.
NOTE
The dressing and bandaging procedure
outlined for the jaw serves a twofold purpose
In addition to stopping the bleeding and
protecting the wound, it also immobilizes a
fractured jaw.
(2) Apply a cravat bandage to the jaw.
(a) Place the bandage under the chin and carry its
ends upward. Adjust the bandage to make one end longer than the other
(Figure 3-20 A).
(b) Take the longer end over the top of the head to
meet the short end at the temple and cross the ends over (Figure 3-20 B).
(c) Take the ends in opposite directions to the other
side of the head and tie them over the part of the bandage that was
applied first (Figure 3-20 C).

bandages attached.
Section III. GIVE PROPER FIRST AID FOR CHEST AND
ABDOMINAL WOUNDS AND BURN INJURIES
3-9. Chest Wounds (081-831-1026)
Chest injuries may be caused by accidents, bullet or missile wounds, stab
wounds, or falls. These injuries can be serious and may cause death
quickly if proper treatment is not given. A casualty with a chest injury
may complain of pain in the chest or shoulder area; he may have difficulty
with his breathing. His chest may not rise normally when he breathes.
The injury may cause the casualty to cough up blood and to have a rapid
or a weak heartbeat. A casualty with an open chest wound has a
punctured chest wall. The sucking sound heard when he breathes is
caused by air leaking into his chest cavity. This particular type of wound
is dangerous and will collapse the injured lung (Figure 3-21). Breathing
becomes difficult for the casualty because the wound is open. The
soldier’s life may depend upon how quickly you make the wound airtight.
3-10. Chest Wound(s) Procedure (081-831-1026)
H a. Evaluate the Casualty (081-831-1000). Be prepared to perform
lifesaving measures. The basic lifesaving measures may include clearing
the airway, rescue breathing, treatment for shock, and/or bleeding
control.
3-23
Figure 3-21. Collapsed lung.
C 2, FM 21-11
b. Expose the Wound. If appropriate, cut or remove the
casualty’s clothing to expose the entire area of the wound. Remember,
DO NOT remove clothing that is stuck to the wound because additional
injury may result. DO NOT attempt to clean the wound.
NOTE
Examine the casualty to see if there is an entry
and/or exit wound. If there are two wounds
(entry, exit), perform the same procedure for
both wounds. Treat the more serious (heavier
bleeding, larger) wound first. It may be
necessary to improvise a dressing for the
second wound by using strips of cloth, such as
a torn T-shirt, or whatever material is
available. Also, listen for sucking sounds to
determine if the chest wall is punctured.
CAUTION
If there is an object extending from (impaled
in) the wound, DO NOT remove the object.
Apply a dressing around the object and use
additional improvised bulky materials/
dressings (use the cleanest materials available)
to buildup the area around the object. Apply a
supporting bandage over the bulky materials
to hold them in place.
CAUTION (081-831-1026)
DO NOT REMOVE protective clothing in a
chemical environment. Apply dressings over
the protective clothing.
c. Open the Casualty’s Field Dressing Plastic Wrapper. The
plastic wrapper is used with the field dressing to create an airtight seal.
If a plastic wrapper is not available, or if an additional wound needs to be
treated; cellophane, foil, the casualty’s poncho, or similar material may
be used. The covering should be wide enough to extend 2 inches or more
beyond the edges of the wound in all directions.
3-24
FM 21-11
(1) Tear open one end of the casualty’s plastic wrapper
covering the field dressing. Be careful not to destroy the wrapper and DO
NOT touch the inside of the wrapper.
(2) Remove the inner packet (field dressing).
(3) Complete tearing open the empty plastic wrapper using
as much of the wrapper as possible to create a flat surface.
d. Place the Wrapper Over the Wound (081-831-1026). Place the
inside surface of the plastic wrapper directly over the wound when the
casualty exhales and hold it in place (Figure 3-22). The casualty may hold
the plastic wrapper in place if he is able.
e. Apply the Dressing to the Wound (081-831-1026).

maintaining pressure on the bandage after it has been tied (Figure 3-26).
Tie the dressing firmly enough to secure the dressing without interfering
with the casualty’s breathing.

NOTE (081-831-1026)
When practical, apply direct manual pressure
over the dressing for 5 to 10 minutes to help
control the bleeding.
f. Position the Casualty (081-831-1026). Position the casualty
on his injured side or in a sitting position, whichever makes breathing
easier (Figure 3-27).
g. Seek Medical Aid. Contact medical personnel.
H WARNING
Even if an airtight dressing has been placed
properly, air may still enter the chest cavity
without having means to escape. This causes a
life-threatening condition called tension
pneumothorax. If the casualty’s condition (for
example, difficulty breathing, shortness of
breath, restlessness, or grayness of skin in a
dark-skinned individual [or blueness in an
individual with light skin]) worsens after
placing the dressing, quickly lift or remove,
then replace the airtight dressing.
3-11. Abdominal Wounds
The most serious abdominal wound is one in which an object penetrates
the abdominal wall and pierces internal organs or large blood vessels. In
these instances, bleeding may be severe and death can occur rapidly.
3-28
Figure 3-27. Casualty positioned (lying) on injured side.
FM 21-11
3-12. Abdominal Wound(s) Procedure (081-831-1025)
a. Evaluate the Casualty. Be prepared to perform basic
lifesaving measures. It is necessary to check for both entry and exit
wounds. If there are two wounds (entry and exit), treat the wound that
appears more serious first (for example, the heavier bleeding, protruding
organs, larger wound, and so forth). It may be necessary to improvise
dressings for the second wound by using strips of cloth, a T-shirt, or the
cleanest material available.
b. Position the Casualty. Place and maintain the casualty on his
back with his knees in an upright (flexed) position (Figure 3-28). The
knees-up position helps relieve pain, assists in the treatment of shock,
prevents further exposure of the bowel (intestines) or abdominal organs,
and helps relieve abdominal pressure by allowing the abdominal muscles
to relax.
c. Expose the Wound.
(1) Remove the casualty’s loose clothing to expose the
wound. However, DO NOT attempt to remove clothing that is stuck to
the wound; it may cause further injury. Thus, remove any loose clothing
from the wound but leave in place the clothing that is stuck.

FM 21-11
CAUTION (081-831-1000 and 081-831-1025)
DO NOT REMOVE protective clothing in a
chemical environment. Apply dressings over
the protective clothing.
(2) Gently pick up any organs which may be on the ground
Do this with a clean, dry dressing or with the cleanest available material,
Place the organs on top of the casualty’s abdomen (Figure 3-29).
NOTE (081-831-1025)
DO NOT probe, clean, or try to remove any
foreign object from the abdomen.
DO NOT touch with bare hands any exposed
organs.
DO NOT push organs back inside the body.
d. Apply the Field Dressing. Use the casualty’s field dressing
not your own. If the field dressing is not large enough to cover the entire
wound, the plastic wrapper from the dressing may be used to cover the
wound first (placing the field dressing on top). Open the plastic wrapper
carefully without touching the inner surface, if possible. If necessary
other improvised dressings may be made from clothing, blankets, or the
cleanest materials available because the field dressing and/or wrapper
may not be large enough to cover the entire wound.

WARNING
If there is an object extending from the wound,
DO NOT remove it. Place as much of the
wrapper over the wound as possible without
dislodging or moving the object. DO NOT
place the wrapper over the object.
(1) Grasp the tails in both hands.
(2) Hold the dressing with the white, or cleanest, side down
directly over the wound.
(3) Pull the dressing open and place it directly over the
wound (Figure 3-30). If the casualty is able, he may hold the dressing in
place.
(4) Hold the dressing in place with one hand and use the
other hand to wrap one of the tails around the body.
(5) Wrap the other tail in the opposite direction until the
dressing is completely covered. Leave enough of the tail for a knot.
(6) Loosely tie the tails with a nonslip knot at the
casualty’s side (Figure 3-31).

FM 21-11
WARNING
When dressing is applied, DO NOT put
pressure on the wound or exposed internal
parts, because pressure could cause further
injury (vomiting, ruptured intestines, and so
forth). Therefore, tie the dressing ties (tails)
loosely at casualty’s side, not directly over the
dressing.
(7) Tie the dressing firmly enough to prevent slipping
without applying pressure to the-wound-site (Figure 3-32). -
Field dressings can be covered with improvised reinforcement material
(cravats, strips of torn T-shirt, or other cloth), if available, for additional
support and protection. Tie improvised bandage on the opposite side of
the dressing ties firmly enough to prevent slipping but without applying
additional pressure to the wound.

FM 21-11
CAUTION (081-831-1025)
DO NOT give casualties with abdominal
wounds food nor water (moistening the lips is
allowed).
e. Seek Medical Aid. Notify medical personnel.
3-13. Burn Injuries
Burns often cause extreme pain, scarring, or even death. Proper
treatment will minimize further injury of the burned area. Before
administering the proper first aid, you must be able to recognize the type
of burn to be treated. There are four types of burns: (1) thermal burns
caused by fire, hot objects, hot liquids, and gases or by nuclear blast or
fire ball; (2) electrical burns caused by electrical wires, current, or
lightning; (3) chemical burns caused by contact with wet or dry chemicals
or white phosphorus (WP)—from marking rounds and grenades; and (4)
laser burns.
3-14. First Aid for Burns (081-831-1007)
a. Eliminate the Source of the Burn. The source of the burn
must be eliminated before any evaluation or treatment of the casualty
can occur.
(1) Remove the casualty quickly and cover the thermal
burn with any large nonsynthetic material, such as a field jacket. Roll the
casualty on the ground to smother (put out) the flames (Figure 3-33).
3-33
Figure 3-33. Casualty covered and rolled on ground.
FM 21-11
CAUTION
Synthetic materials, such as nylon, may melt
and cause further injury.
(2) Remove the electrical burn casualty from the electrical
source by turning off the electrical current. DO NOT attempt to turn off
the electricity if the source is not close by. Speed is critical, so DO NOT
waste unnecessary time. If the electricity cannot be turned off, wrap any
nonconductive material (dry rope, dry clothing, dry wood, and so forth)
around the casualty’s back and shoulders and drag the casualty away
from the electrical source (Figure 3-34). DO NOT make body-to-body
contact with the casualty or touch any wires because you could also
become an electrical burn casualty.
WARNING
High voltage electrical burns may cause
temporary unconsciousness, difficulties in
breathing, or difficulties with the heart
(heartbeat).
(3) Remove the chemical from the burned casualty. Remove
liquid chemicals by flushing with as much water as possible. If water is
not available, use any nonflammable fluid to flush chemicals off the
3-34
Figure 3-34. Casualty removed from electrical source (using
nonconductive material).
FM 21-11
casualty. Remove dry chemicals by brushing off loose particles (DO NOT
use the bare surface of your hand because you could become a chemical
burn casualty) and then flush with large amounts of water, if available. If
large amounts of water are not available, then NO water should be
applied because small amounts of water applied to a dry chemical burn
may cause a chemical reaction. When white phosphorous strikes the skin,
smother with water, a wet cloth, or wet mud. Keep white phosphorous
covered with a wet material to exclude air which will prevent the particles
from burning.
WARNING
Small amounts of water applied to a dry
chemical burn may cause a chemical reaction,
transforming the dry chemical into an active
burning substance.
(4) Remove the laser burn casualty from the source.
(NOTE: Lasers produce a narrow amplified beam of light. The word
laser means Light Amplification by Stimulated E mission of Radiation
and sources include range finders, weapons/guidance, communication
systems, and weapons simulations such as MILES.) When removing the
casualty from the laser beam source, be careful not to enter the beam or
you may become a casualty. Never look directly at the beam source and if
possible, wear appropriate eye protection.
NOTE
After the casualty is removed from the source
of the burn, he should be evaluated for
conditions requiring basic lifesaving measures
(Evaluate the Casualty).
b. Expose the Burn. Cut and gently lift away any clothing
covering the burned area, without pulling clothing over the burns. Leave
in place any clothing that is stuck to the burns. If the casualty’s hands or
wrists have been burned, remove jewelry if possible without causing
further injury (rings, watches, and so forth) and place in his pockets. This
prevents the necessity to cut off jewelry since swelling usually occurs as
a result of a burn.
3-35
FM 21-11
CAUTION (081-831-1007)
DO NOT lift or cut away clothing if in a
chemical environment. Apply the dressing
directly over the casualty’s protective
clothing.
DO NOT attempt to decontaminate skin where
blisters have formed.
c. Apply a Field Dressing to the Burn.
(1) Grasp the tails of the casualty’s dressing in both hands.
(2) Hold the dressing directly over the wound with the
white (sterile) side down, pull the dressing open, and place it directly over
the wound. If the casualty is able, he may hold the dressing in place.
(3) Hold the dressing in place with one hand and use the
other hand to wrap one of the tails around the limbs or the body.
(4) Wrap the other tail in the opposite direction until the
dressing is completely covered.
(5) Tie the tails into a knot over the outer edge of the
dressing. The dressing should be applied lightly over the burn. Ensure
that dressing is applied firmly enough to prevent it from slipping.
NOTE
Use the cleanest improvised dressing material
available if a field dressing is not available or if
it is not large enough for the entire wound.
d. Take the Following Precautions (081-831-1007):
DO NOT place the dressing over the face or genital area.
DO NOT break the blisters.
DO NOT apply grease or ointments to the burns.
For electrical burns, check for both an entry and exit
burn from the passage of electricity through the body. Exit burns may
appear on any area of the body despite location of entry burn.

For burns caused by white phosphorus (WP), flush the
area with water, then cover with a wet material, dressing, or mud to
exclude the air and keep the WP particles from burning.
For laser burns, apply a field dressing.
If the casualty is conscious and not nauseated, give him
small amounts of water.
e. Seek Medical Aid. Notify medical personnel.

CHAPTER 4
FIRST AID FOR FRACTURES
INTRODUCTION
A fracture is any break in the continuity of a bone. Fractures can cause
total disability or in some cases death. On the other hand, they can most
often be treated so there is complete recovery. A great deal depends upon
the first aid the individual receives before he is moved. First aid includes
immobilizing the fractured part in addition to applying lifesaving
measures. The basic splinting principle is to immobilize the joints above
and below any fracture.
4-1. Kinds of Fractures
See figure 4-1 for detailed illustration.
a. Closed Fracture. A closed fracture is a broken bone that does
not break the overlying skin. Tissue beneath the skin may be damaged. A
dislocation is when a joint, such as a knee, ankle, or shoulder, is not in
proper position. A sprain is when the connecting tissues of the joints
have been torn. Dislocations and sprains should be treated as closed
fractures.
b. Open Fracture. An open fracture is a broken bone that breaks
(pierces) the overlying skin. The broken bone may come through the skin,

FM 21-11
or a missile such as a bullet or shell fragment may go through the flesh
and break the bone. An open fracture is contaminated and subject to
infection.
4-2. Signs/Symptoms of Fractures (081-831-1000)
Indications of a fracture are deformity, tenderness, swelling, pain,
inability to move the injured part, protruding bone, bleeding, or
discolored skin at the injury site. A sharp pain when the individual
attempts to move the part is also a sign of a fracture. DO NOT encourage
the casualty to move the injured part in order to identify a fracture since
such movement could cause further damage to surrounding tissues and
promote shock. If you are not sure whether a bone is fractured, treat the
injury as a fracture.
4-3. Purposes of Immobilizing Fractures
A fracture is immobilized to prevent the sharp edges of the bone from
moving and cutting tissue, muscle, blood vessels, and nerves. This
reduces pain and helps prevent or control shock. In a closed fracture,
immobilization keeps bone fragments from causing an open wound and
prevents contamination and possible infection. Splint to immobilize.
4-4. Splints, Padding, Bandages, Slings, and Swathes
(081-831-1034)
a. Splints. Splints may be improvised from such items as
boards, poles, sticks, tree limbs, rolled magazines, rolled newspapers, or
cardboard. If nothing is available for a splint, the chest wall can be used
to immobilize a fractured arm and the uninjured leg can be used to
immobilize (to some extent) the fractured leg.
b. Padding. Padding may be improvised from such items as a
jacket, blanket, poncho, shelter half, or leafy vegetation.
c. Bandages. Bandages may be improvised from belts, rifle
slings, bandoleers, kerchiefs, or strips torn from clothing or blankets.
Narrow materials such as wire or cord should not be used to secure a
splint in place.
d. Slings. A sling is a bandage (or improvised material such as a
piece of cloth, a belt, and so forth) suspended from the neck to support an
upper extremity. Also, slings may be improvised by using the tail of a
coat or shirt, and pieces torn from such items as clothing and blankets.
The triangular bandage is ideal for this purpose. Remember that the
casualty’s hand should be higher than his elbow, and the sling should be
applied so that the supporting pressure is on the uninjured side.
4-2
C 2, FM 21-11
e. Swathes. Swathes are any bands (pieces of cloth, pistol belts,
and so forth) that are used to further immobilize a splinted fracture.
Triangular and cravat bandages are often used as or referred to as swathe
bandages. The purpose of the swathe is to immobilize, therefore, the
swathe bandage is placed above and/or below the fracture—not over it.
4-5. Procedures for Splinting Suspected Fractures (081-831-1034)
Before beginning first aid treatment for a fracture, gather whatever
splinting materials are available. Materials may consist of splints, such
as wooden boards, branches, or poles. Other splinting materials include
padding, improvised cravats, and/or bandages, Ensure that splints are
long enough to immobilize the joint above and below the suspected
fracture. If possible, use at least four ties (two above and two below the
fracture) to secure the splints. The ties should be nonslip knots and
should be tied away from the body on the splint.
H a. Evaluate the Casualty (081-831-1000). Be prepared to perform
my necessary lifesaving measures. Monitor the casualty for
development of conditions which may require you to perform necessary
basic lifesaving measures. These measures include clearing the airway,
rescue breathing, preventing shock, and/or bleeding control.
WARNING (081-831-1000)
Unless there is immediate life-threatening
danger, such as a fire or an explosion, DO NOT
move the casualty with a suspected back or
neck injury. Improper movement may cause
permanent paralysis or death.
WARNING (081-831-1000)
In a chemical environment, DO NOT remove
any protective clothing. Apply the
dressing/splint over the clothing.
b. Locate the Site of the Suspected Fracture. Ask the casualty
for the location of the injury. Does he have any pain? Where is it tender?
Can he move the extremity? Look for an unnatural position of the
extremity. Look for a bone sticking out (protruding).
c. Prepare
(081-831-1034).
the Casualty for Splinting the Suspected Fracture
4-3
C 2, FM 21-11
(1) Reassure the casualty. Tell him that you will be taking
care of him and that medical aid is on the way.
(2) Loosen any tight or binding clothing.
(3) Remove all the jewelry from the casualty and place it in
the casualty’s pocket. Tell the casualty you are doing this because if the
jewelry is not removed at this time and swelling occurs later, further
bodily injury can occur.
NOTE
Boots should not be removed from the casualty
unless they are needed to stabilize a neck
injury, or there is actual bleeding from the
foot.
d. Gather Splinting Materials (081-831-1034). If standard
splinting materials (splints, padding, cravats, and so forth) are not
available, gather improvised materials. Splints can be improvised from
wooden boards, tree branches, poles, rolled newspapers or magazines.
Splints should be long enough to reach beyond the joints above and
below the suspected fracture site. Improvised padding, such as a jacket,
blanket, poncho, shelter half, or leafy vegetation may be used. A cravat
can be improvised from a piece of cloth, a large bandage, a shirt, or a
towel. Also, to immobilize a suspected fracture of an arm or a leg, parts of
the casualty’s body may be used. For example, the chest wall may be
used to immobilize an arm; and the uninjured leg may be used to
immobilize the injured leg.
NOTE
If splinting material is not available and
suspected fracture CANNOT be splinted, then
swathes, or a combination of swathes and
slings can be used to immobilize an extremity.
e. Pad the Splints (081-831-1034). Pad the splints where they
touch any bony part of the body, such as the elbow, wrist, knee, ankle,
crotch, or armpit area. Padding prevents excessive pressure to the area.
f. Check the Circulation Below the Site of the Injury (081-831-1034).
(1) Note any pale, white, or bluish-gray color of the skin
which may indicate impaired circulation. Circulation can also be checked
4-4
FM 21-11
by depressing the toe/fingernail beds and observing how quickly the color
returns. A slower return of pink color to the injured side when compared
with the uninjured side indicates a problem with circulation. Depressing
the toe/fingernail beds is a method to use to check the circulation in a
dark-skinned casualty.
(2) Check the temperature of the injured extremity. Use
your hand to compare the temperature of the injured side with the
uninjured side of the body. The body area below the injury maybe colder
to the touch indicating poor circulation.
(3) Question the casualty about the presence of numbness,
tightness, cold, or tingling sensations.
WARNING
Casualties with fractures to the extremities
may show impaired circulation, such as
numbness, tingling, cold and/or pale to blue
skin. These casualties should be evacuated by
medical personnel and treated as soon as
possible. Prompt medical treatment may
prevent possible loss of the limb.
WARNING
If it is an open fracture (skin is broken; bone(s)
may be sticking out), DO NOT ATTEMPT TO
PUSH BONE(S) BACK UNDER THE SKIN.
Apply a field dressing to protect the area. See
Task 081-831-1016, Put on a Field or Pressure
Dressing.
g. Apply the Splint in Place (081-831-1034).
(1) Splint the fracture(s) in the position found. DO NOT
attempt to reposition or straighten the injury. If it is an open fracture,
stop the bleeding and protect the wound. (See Chapter 2, Section II, for
detailed information.) Cover all wounds with field dressings before
applying a splint. Remember to use the casualty’s field dressing, not
your own. If bones are protruding (sticking out), DO NOT attempt to
push them back under the skin. Apply dressings to protect the area.
4-5
FM 21-11
(2) Place one splint on each side of the arm or leg. Make
sure that the splints reach, if possible, beyond the joints above and below
the fracture.
(3) Tie the splints. Secure each splint in place above and
below the fracture site with improvised (or actual) cravats. Improvised
cravats, such as strips of cloth, belts, or whatever else you have, may be
used. With minimal motion to the injured areas, place and tie the splints
with the bandages. Push cravats through and under the natural bodv.
curvatures (spaces), and then gently position improvised cravats and tie
in place. Use nonslip knots. Tie all knots on the splint away from the
casualty (Figure 4-2). DO NOT tie cravats directly over suspected
fracture/dislocation site.
h. Check the Splint for Tightness (081-831-1034).
(1) Check to be sure that bandages are tight enough to
securely hold splinting materials in place, but not so tight that
circulation is impaired.
(2) Recheck the circulation after application of the splint.
Check the skin color and temperature. This is to ensure that the bandages
holding the splint in place have not been tied too tightly. A finger tip
check can be made by inserting the tip of the finger between the wrapped
tails and the skin.
(3) Make any adjustment without allowing the splint to
become ineffective.
i. Apply a Sling if Applicable (081-831-1034). An improvised
sling may be made from any available nonstretching piece of cloth, such
as a fatigue shirt or trouser, poncho, or shelter half. Slings may also be
improvised using the tail of a coat, belt, or a piece of cloth from a blanket
or some clothing. See Figure 4-3 for an illustration of a shirt tail used for
4-6

FM 21-11
support. A pistol belt or trouser belt also may be used for support (Figure
4-4). A sling should place the supporting pressure on the casualty’s
uninjured side. The supported arm should have the hand positioned
slightly higher than the elbow.
(1) Insert the splinted arm in the center of the sling (Figure
4-5).

(or hollow) of the neck on the uninjured side (Figure 4-6).
(3) Twist and tuck the corner of the sling at the elbow
(Figure 4-7).

FM 21-11
j. Apply a Swathe if Applicable (081-831-1034). You may use
any large piece of cloth, such as a soldier’s belt or pistol belt, to improvise
a swathe. A swathe is any band (a piece of cloth) or wrapping used to
further immobilize a fracture. When splints are unavailable, swathes, or a
combination of swathes and slings can be used to immobilize an
extremity.
WARNING (081-831-1034)
The swathe should not be placed directly on
top of the injury, but positioned either above
and/or below the fracture site.
(1) Apply swathes to the injured arm by wrapping the
swathe over the injured arm, around the casualty’s back and under the
arm on the uninjured side. Tie the ends on the uninjured side (Figure 4-8).
(2) A swathe is applied to an injured leg by wrapping the
swathe(s) around both legs and securing it on the uninjured side.
k. Seek Medical Aid. Notify medical personnel, watch closely
for development of life-threatening conditions, and if necessary, continue
to evaluate the casualty.

treated as a fracture. Remember, if the spine is fractured, bending it can
cause the sharp bone fragments to bruise or cut the spinal cord and result
in permanent paralysis (Figure 4-26A). The spinal column must maintain
a swayback position to remove pressure from the spinal cord.
a. If the Casualty Is Not to Be Transported (081-831-1000) Until
Medical Personnel Arrive—
Caution him not to move. Ask him if he is in pain or if he
is unable to move any part of his body.
Leave him in the position in which he is found. DO NOT
move any part of his body.
Slip a blanket, if he is lying face up, or material of similar
size, under the arch of his back to support the spinal column in a
swayback position (Figure 4-26 B). If he is lying face down, DO NOT put
anything under any part of his body.

longer than his height. Loosely tie the casualty’s wrists together over his
waistline, using a cravat or a strip of cloth. Tie his feet together to
prevent the accidental dropping or shifting of his legs. Lay a folded
blanket across the litter where the arch of his back is to be placed. Using
a four-man team (Figure 4-27), place the casualty on the litter without
bending his spinal column or his neck.

o The number two, three, and four men position
themselves on one side of the casualty; all kneel on one knee along the
side of the casualty. The number one man positions himself to the
opposite side of the casualty. The number two, three, and four men gently
place their hands under the casualty. The number one man on the
opposite side places his hands under the injured part to assist.
o When all four men are in position to lift, the number
two man commands, “PREPARE TO LIFT” and then, “LIFT.” All
men, in unison, gently lift the casualty about 8 inches. Once the casualty
is lifted, the number one man recovers and slides the litter under the
casualty, ensuring that the blanket is in proper position. The number one
man then returns to his original lift position (Figure 4-27).
o When the number two man commands, “LOWER
CASUALTY,” all men, in unison, gently lower the casualty onto the
litter.
And if the casualty is in a face-down position, he must be
transported in this same position. The four-man team lifts him onto a
regular or improvised litter, keeping the spinal column in a swayback
position. If a regular litter is used, first place a folded blanket on the litter
at the point where the chest will be placed.
4-10. Neck Fractures (081-831-1000)
A fractured neck is extremely dangerous. Bone fragments may bruise or
cut the spinal cord just as they might in a fractured back.
a. If the Casualty Is Not to Be Transported (081-831-1000) Until
Medical Personnel Arrive—
Caution him not to move. Moving may cause death.
Leave the casualty in the position in which he is found. If
his neck/head is in an abnormal position, immediately immobilize the
neck/head. Use the procedure stated below.
o Keep the casualty‘s head still, if he is lying face up,
raise his shoulders slightly, and slip a roll of cloth that has the bulk of a
bath towel under his neck (Figure 4-28). The roll should be thick enough
to arch his neck only slightly, leaving the back of his head on the ground.
DO NOT bend his neck or head forward. DO NOT raise or twist his head.

b. If the Casualty Must be Prepared for Transportation Before
Medical Personnel Arrive—
And he has a fractured neck, at least two persons are
needed because the casualty’s head and trunk must be moved in unison.
The two persons must work in close coordination (Figure 4-30) to avoid
bending the neck.
Place a wide board lengthwise beside the casualty. It
should extend at least 4 inches beyond the casualty‘s head and feet
(Figure 4-30 A).
If the casualty is lying face up, the number one man
steadies the casualty’s head and neck between his hands. At the same
time the number two man positions one foot and one knee against the
board to prevent it from slipping, grasps the casualty underneath his
shoulder and hip, and gently slides him onto the board (Figure 4-30 B).
If the casualty is lying face down, the number one man
steadies the casualty’s head and neck between his hands, while the
number two man gently rolls the casualty over onto the board (Figure
4-30 C).
The number one man continues to steady the casualty’s
head and neck. The number two man simultaneously raises the casualty’s
shoulders slightly, places padding under his neck, and immobilizes the
casualty’s head (Figures 4-30 D, and E). The head may be immobilized
with the casualty’s boots, with stones rolled in pieces of blanket, or with
other material.
Secure any improvised supports in position with a cravat
or strip of cloth extended across the casualty’s forehead and under the
board (Figure 4-30 D).
Lift the board onto a litter or blanket in order to
transport the casualty (Figure 4-30 E).

CHAPTER 5
FIRST AID FOR CLIMATIC INJURIES
INTRODUCTION
It is desirable, but not always possible, for an individual’s body to
become adjusted (acclimatized) to an environment. Physical condition
determines the time adjustment, and trying to rush it is ineffective. Even
those individuals in good physical condition need time before working or
training in extremes of hot or cold weather. Climate-related injuries are
usually preventable; prevention is both an individual and leadership
responsibility. Several factors contribute to health and well-being in any
environment: diet, sleep/rest, exercise, and suitable clothing. These
factors are particularly important in extremes of weather. Diet,
especially, should be suited to an individual’s needs in a particular
climate. A special diet undertaken for any purpose should be done so with
appropriate supervision. This will ensure that the individual is getting a
properly balanced diet suited to both climate and personal needs,
whether for weight reduction or other purposes. The wearing of
specialized protective gear or clothing will sometimes add to the problem
of adjusting to a particular climate. Therefore, soldiers should exercise
caution and judgment in adding or removing specialized protective gear
or clothing.
5-1. Heat Injuries (081-831-1008)
Heat injuries are environmental injuries that may result when a soldier is
exposed to extreme heat, such as from the sun or from high
temperatures. Prevention depends on availability and consumption of
adequate amounts of water. Prevention also depends on proper clothing
and appropriate activity levels. Acclimatization and protection from
undue heat exposure are also very important. Identification of high risk
personnel (basic trainees, troops with previous history of heat injury, and
overweight soldiers) helps both the leadership and the individual prevent
and cope with climatic conditions. Instruction on living and working in
hot climates also contributes toward prevention.
NOTE
Salt tablets should not be used in the
prevention of heat injury. Usually, eating field
rations or liberal salting of the garrison diet
will provide enough salt to replace what is lost
through sweating in hot weather.
5-1
FM 21-31
a. Diet. A balanced diet usually provides enough salt even in
hot weather. But when people are on reducing or other diets, salt may
need to come from other sources. DO NOT use salt tablets to supplement
a diet. Anyone on a special diet (for whatever purpose) should obtain
professional help to work out a properly balanced diet.
b. Clothing.
(1) The type and amount of clothing and equipment a
soldier wears and the way he wears it also affect the body and its
adjustment to the environment. Clothing protects the body from radiant
heat. However, excessive or tight-fitting clothing, web equipment, and
packs reduce ventilation needed to cool the body. During halts, rest
stops, and other periods when such items are not needed, they should be
removed, mission permitting.
(2) The individual protective equipment (IPE) protects the
soldier from chemical and biological agents. The equipment provides a
barrier between him and a toxic environment. However, a serious
problem associated with the chemical overgarment is heat stress. The
body normally maintains a heat balance, but when the overgarment is
worn the body sometimes does not function properly. Overheating may
occur rapidly. Therefore, strict adherence to mission oriented protective
posture (MOPP) levels directed by your commander is important. This
will keep those heat related injuries caused by wearing the IPE to a
minimum. See FM 3-4 for further information on MOPP.
c. Prevention. The ideal fluid replacement is water. The
availability of sufficient water during work or training in hot weather is
very important. The body, which depends on water to help cool itself, can
lose more than a quart of water per hour through sweat. Lost fluids must
be replaced quickly. Therefore, during these work or training periods, you
should drink at least one canteen full of water every hour. In extremely
hot climates or extreme temperatures, drink at least a full canteen of
water every half hour, if possible. In such hot climates, the body depends
mainly upon sweating to keep it cool, and water intake must be
maintained to allow sweating to continue. Also, keep in mind that a
person who has suffered one heat injury is likely to suffer another. Before
a heat injury casualty returns to work, he should have recovered well
enough not to risk a recurrence. Other conditions which may increase
heat stress and cause heat injury include infections, fever, recent illness
or injury, overweight, dehydration, exertion, fatigue, heavy meals, and
alcohol. In all this, note that salt tablets should not be used as a
preventive measure.
d. Categories. Heat injury can be divided into three categories:
heat cramps, heat exhaustion, and heatstroke.
5-2
C2, FM 21-11
e. First Aid. Recognize and give first aid for heat injuries.
WARNING
Casualty should be continually monitored for
development of conditions which may require
the performance of necessary basic lifesaving
measures, such as: clearing the airway,
performing mouth-to-mouth resuscitation,
preventing shock, and/or bleeding control.
H CAUTION
DO NOT use salt solution in first aid
procedures for heat injuries.
(1) Check the casualty for signs and symptoms of heat
cramps (081-831-1008).
Signs/Symptoms. Heat cramps are caused by an
imbalance of chemicals (called electrolytes) in the body as a result of
excessive sweating. This condition causes the casualty to exhibit:
o Muscle cramps in the extremities (arms and
legs).
o Muscle cramps of the abdomen.
o Heavy (excessive) sweating (wet skin).
o Thirst.
Treatment.
o Move the casualty to a cool or shady area (or
improvise shade).
o Loosen his clothing (if not in a chemical
environment).
o Have him slowly drink at least one canteen full
of cool water.
o Seek medical aid should cramps continue.
WARNING
DO NOT loosen the casualty’s clothing if in a
chemical environment.

(2) Check the casualty for signs and symptoms of heat
exhaustion (081-831-1008).
Signs/Symptoms which occur often. Heat
exhaustion is caused by loss of water through sweating without adequate
fluid replacement. It can occur in an otherwise fit individual who is
involved in tremendous physical exertion in any hot environment. The
signs and symptoms are similar to those which develop when a person
goes into a state of shock.
o Heavy (excessive) sweating with pale, moist,
cool skin.
o Headache.
o Weakness.
o Dizziness.
o Loss of appetite.
Signs/Symptoms which occur sometimes.
o Heat cramps.
o Nausea—with or without vomiting.
o Urge to defecate.
o Chills (gooseflesh).
o Rapid breathing.
o Tingling of hands and/or feet.
o Confusion.
Treatment.
o Move the casualty to a cool or shady area (or
improvise shade).
o Loosen or remove his clothing and boots (unless
in a chemical environment). Pour water on him and fan him (unless in a
chemical environment).
o Have him slowly drink at least one canteen full
of cool water.

C 2, FM 21-11
o Elevate his legs.
o If possible, the casualty should not participate
in strenuous activity for the remainder of the day.
o Monitor the casualty until the symptoms are
gone, or medical aid arrives.
(3) Check the casualty for signs and symptoms of
heatstroke (sometimes called “sunstroke") (081-831-1008).
WARNING
Heatstroke must be considered a medical
emergency which may result in death if
treatment is delayed.
Signs/Symptoms. A casualty suffering from
heatstroke has usually worked in a very hot, humid environment for a
prolonged time. It is caused by failure of the body’s cooling mechanisms.
Inadequate sweating is a factor. The casualty’s skin is red (flushed), hot,
and dry. He may experience weakness, dizziness, confusion, headaches,
seizures, nausea (stomach pains), and his respiration and pulse may be
rapid and weak. Unconsciousness and collapse may occur suddenly.
Treatment. Cool casualty immediately by—
o Moving him to a cool or shaded area (or
improvise shade).
o Loosening or removing his clothing (except in a
chemical environment).
H o Spraying or pouring water on him; fanning him
to permit a coolant effect of evaporation.
o Massaging his extremities and skin which
increases the blood flow to those body areas, thus aiding the cooling
process.
o Elevating his legs.
o Having him slowly drink at least one canteen
full of water if he is conscious.

NOTE
Start cooling casualty immediately. Continue
cooling while awaiting transportation and
during the evacuation.
Medical aid. Seek medical aid because the casualty
should be transported to a medical treatment facility as soon as possible.
Do not interrupt cooling process or lifesaving measures to seek help.
Casualty should be continually monitored for
development of conditions which may require the performance of
necessary basic lifesaving measures, such as clearing the airway, mouthto-
mouth resuscitation, preventing shock, and/or bleeding control.

5-2. Cold Injuries (081-831-1009)
Cold injuries are most likely to occur when an unprepared individual is
exposed to winter temperatures. They can occur even with proper
planning and equipment. The cold weather and the type of combat
operation in which the individual is involved impact on whether he is
likely to be injured and to what extent. His clothing, his physical
condition, and his mental makeup also are determining factors. However,
cold injuries can usually be prevented. Well-disciplined and well-trained
individuals can be protected even in the most adverse circumstances.
They and their leaders must know the hazards of exposure to the cold.
They must know the importance of personal hygiene, exercise, care of the
feet and hands, and the use of protective clothing.
a. Contributing Factors.
(1) Weather. Temperature, humidity, precipitation, and
wind modify the loss of body heat. Low temperatures and low relative
humidity-dry cold—promote frostbite. Higher temperatures, together
with moisture, promote immersion syndrome. Windchill accelerates the
loss of body heat and may aggravate cold injuries. These principles and
risks apply equally to both men and women.
(2) Type of combat operation. Defense, delaying,
observation-post, and sentinel duties do create to a greater extent—fear,
fatigue, dehydration, and lack of nutrition. These factors further increase
the soldier’s vulnerability to cold injury. Also, a soldier is more likely to
receive a cold injury if he is—
Often in contact with the ground.
Immobile for long periods, such as while riding in a
crowded vehicle.
Standing in water, such as in a foxhole.
Out in the cold for days without being warmed.
Deprived of an adequate diet and rest.
Not able to take care of his personal hygiene.
(3) Clothing. The soldier should wear several layers of loose
clothing. He should dress as lightly as possible consistent with the
weather to reduce the danger of excessive perspiration and subsequent
chilling. It is better for the body to be slightly cold and generating heat
than excessively warm and sweltering toward dehydration. He should
5-8
•
•
•
•
•
•
FM 21-11
remove a layer or two of clothing before doing any hard work. He should
replace the clothing when work is completed. Most cold injuries result
from soldiers having too few clothes available when the weather suddenly
turns colder. Wet gloves, shoes, socks, or any other wet clothing add to
the cold injury process.
CAUTION
In a chemical environment DO NOT take off
protective chemical gear.
(4) Physical makeup. Physical fatigue contributes to
apathy, which leads to inactivity, personal neglect, carelessness, and
reduced heat production. In turn, these increase the risk of cold injury.
Soldiers with prior cold injuries have a higher-than-normal risk of
subsequent cold injury, not necessarily involving the part previously
injured.
(5) Psychological factor. Mental fatigue and fear reduces
the body’s ability to rewarm itself and thus increases the incidence of
cold injury. The feelings of isolation imposed by the environment are also
stressful. Depressed and/or unresponsive soldiers are also vulnerable
because they are less active. These soldiers tend to be careless about
precautionary measures, especially warming activities, when cold injury
is a threat.
b. Signs/Symptoms. Once a soldier becomes familiar with the
factors that contribute to cold injury, he must learn to recognize cold
injury signs/symptoms.
(1) Many soldiers suffer cold injury without realizing what
is happening to them. They may be cold and generally uncomfortable.
These soldiers often do not notice the injured part because it is already
numb from the cold.
(2) Superficial cold injury usually can be detected by
numbness, tingling, or “pins and needles” sensations. These
signs/symptoms often can be relieved simply by loosening boots or other
clothing and by exercising to improve circulation. In more serious cases
involving deep cold injury, the soldier often is not aware that there is a
problem until the affected part feels like a stump or block of wood.
(3) Outward signs of cold injury include discoloration of the
skin at the site of injury. In light-skinned persons, the skin first reddens
and then becomes pale or waxy white. In dark-skinned persons, grayness
in the skin is usually evident. An injured foot or hand feels cold to the
5-9
FM 21-11
touch. Swelling may be an indication of deep injury. Also note that
blisters may occur after rewarming the affected parts. Soldiers should
work in pairs—buddy teams—to check each other for signs of
discoloration and other symptoms. Leaders should also be alert for signs
of cold injuries.
c. Treatment Considerations. First aid for cold injuries depends
on whether they are superficial or deep. Cases of superficial cold injury
can be adequately treated by warming the affected part using body heat.
For example, this can be done by covering cheeks with hands, putting
fingertips under armpits, or placing feet under the clothing of a buddy
next to his belly. The injured part should NOT be massaged, exposed to a
fire or stove, rubbed with snow, slapped, chafed, or soaked in cold water.
Walking on injured feet should be avoided. Deep cold injury (frostbite) is
very serious and requires more aggressive first aid to avoid or to
minimize the loss of parts of the fingers, toes, hands, or feet. The
sequence for treating cold injuries depends on whether the condition is
life-threatening. That is, PRIORITY is given to removing the casualty
from the cold. Other-than-cold injuries are treated either simultaneously
while waiting for evacuation to a medical treatment facility or while en
route to the facility.
NOTE
The injured soldier should be evacuated at
once to a place where the affected part can be
rewarmed under medical supervision.
d. Conditions Caused by Cold. Conditions caused by cold are
chilblain, immersion syndrome (immersion foot/trench foot), frostbite,
snow blindness, dehydration, and hypothermia.
(1) Chilblain.
Signs/Symptoms. Chilblain is caused by repeated
prolonged exposure of bare skin at temperatures from 60°F, to 32°F, or
200F for acclimated, dry, unwashed skin. The area may be acutely
swollen, red, tender, and hot with itchy skin. There may be no loss of skin
tissue in untreated cases but continued exposure may lead to infected,
ulcerated, or bleeding lesions.
Treatment. Within minutes, the area usually
responds to locally applied body heat. Rewarm the affected part by
applying firm steady pressure with your hands, or placing the affected
part under your arms or against the stomach of a buddy. DO NOT rub or
5-10
•
•
FM 21-11
massage affected areas. Medical personnel should evaluate the injury,
because signs and symptoms of tissue damage may be slow to appear.
Prevention. Prevention of chilblain depends cm
basic cold injury prevention methods. Caring for and wearing the
uniform properly and staying dry (as far as conditions permit) are of
immediate importance.
(2) Immersion syndrome (immersion foot/trench foot).
Immersion foot and trench foot are injuries that result from fairly long
exposure of the feet to wet conditions at temperatures from
approximately 50° to 32°F. Inactive feet in damp or wet socks and boots,
or tightly laced boots which impair circulation are even more susceptible
to injury. This injury can be very serious; it can lead to loss of toes or
parts of the feet. If exposure of the feet has been prolonged and severe,
the feet may swell so much that pressure closes the blood vessels and
cuts off circulation. Should an immersion injury occur, dry the feet
thoroughly; and evacuate the casualty to a medical treatment facility by
the fastest means possible.
Signs/Symptoms. At first, the parts of the affected
foot are cold and painless, the pulse is weak, and numbness may be
present. Second, the parts may feel hot, and burning and shooting pains
may begin. In later stages, the skin is pale with a bluish cast and the
pulse decreases. Other signs/symptoms that may follow are blistering,
swelling, redness, heat, hemorrhages (bleeding), and gangrene.
Treatment. Treatment is required for all stages of
immersion syndrome injury. Rewarm the injured part gradually by
exposing it to warm air. DO NOT massage it. DO NOT moisten the skin
and DO NOT apply heat or ice. Protect it from trauma and secondary
infections. Dry, loose clothing or several layers of warm coverings are
preferable to extreme heat. Under no circumstances should the injured
part be exposed to an open fire. Elevate the injured part to relieve the
swelling. Evacuate the casualty to a medical treatment facility as soon as
possible. When the part is rewarmed, the casualty often feels a burning
sensation and pain. Symptoms may persist for days or weeks even after
rewarming.
Prevention. Immersion syndrome can be prevented
by good hygienic care of the feet and avoiding moist conditions for
prolonged periods. Changing socks at least daily (depending on
environmental conditions) is also a preventive measure. Wet socks can be
air dried, then can be placed inside the shirt to warm them prior to
putting them on.

(3) Frostbite. Frostbite is the injury of tissue caused from
exposure to cold, usually below 32°F depending on the windchill factor,
duration of exposure, and adequacy of protection. Individuals with a
history of cold injury are likely to be more easily affected for an indefinite
period. The body parts most easily frostbitten are the cheeks, nose, ears,
chin, forehead, wrists, hands, and feet. Proper treatment and
management depend upon accurate diagnosis. Frostbite may involve
only the skin (superficial), or it may extend to a depth below the skin
(deep). Deep frostbite is very serious and requires more aggressive first
aid to avoid or to minimize the loss of parts of the fingers, toes, hands, or
feet.
WARNING
Casualty should be continually monitored for
development of conditions which may require
the performance of necessary basic lifesaving
measures, such as clearing the airway,
performing mouth-to-mouth resuscitation,
preventing shock, and/or bleeding control.
Progressive signs/symptoms (081-831-1009).
o Loss of sensation, or numb feeling in any par
of the body.

•
FM 21-11
CAUTION
Deep frostbite is a very serious injury and
requires immediate first aid and subsequent
medical treatment to avoid or minimize loss of
body parts.
Treatment (081-831-1009).
o Face, ears, and nose. Cover the casualty‘s
affected area with his and/or your bare hands until sensation and color
return.
o Hands. Open the casualty’s field jacket and
shirt. (In a chemical environment never remove the clothing. ) Place the
affected hands under the casualty’s armpits. Close the field jacket and
shirt to prevent additional exposure.
o Feet. Remove the casualty’s boots and socks if
he does not need to walk any further to receive additional treatment.
(Thawing the casualty’s feet and forcing him to walk on them will cause
additional pain/injury. ) Place the affected feet under clothing and against
the body of another soldier.
WARNING (081-831-1009)
DO NOT attempt to thaw the casualty’s feet
or other seriously frozen areas if he will be
required to walk or travel to receive further
treatment. The casualty should avoid walking,
if possible, because there is less danger in
walking while the feet are frozen than after
they have been thawed. Thawing in the field
increases the possibilities of infection,
gangrene, or other injury.
NOTE
Thawing may occur spontaneously during
transportation to the medical facility; this
cannot be avoided since the body in general
must be kept warm.
In all of the above areas, ensure that the casualty is kept warm and that
he is covered (to avoid further injury). Seek medical treatment as soon as
5-13
•
FM 21-11
possible. Reassure the casualty, protect the affected area from further
injury by covering it lightly with a blanket or any dry clothing, and seek
shelter out of the wind. Remove/minimize constricting clothing and
increase insulation. Ensure that the casualty exercises as much as
possible, avoiding trauma to the injured part, and is prepared for pain
when thawing occurs. Protect the frostbitten part from additional injury.
DO NOT rub the injured part with snow or apply cold water soaks. DO
NOT warm the part by massage or exposure to open fire because the
frozen part may be burned due to the lack of feeling. DO NOT use
ointments or other medications. DO NOT manipulate the part in any way
to increase circulation. DO NOT allow the casualty to use alcohol or
tobacco because this reduces the body’s resistance to cold. Remember,
when freezing extends to a depth below the skin, it involves a much more
serious injury. Extra care is required to reduce or avoid the chances of
losing all or part of the toes or feet. This also applies to the fingers and
hands.
Prevention. Prevention of frostbite or any cold
injury depends on adequate nutrition, hot meals and warm fluids. Other
cold injury preventive factors are proper clothing and maintenance of
general body temperature. Fatigue, dehydration, tobacco, and alcoholic
beverages should be avoided.
o Sufficient clothing must be worn for protection
against cold and wind. Layers of clothing that can be removed and
replaced as needed are the most effective. Every effort must be made to
keep clothing and body as dry as possible. This includes avoiding any
excessive perspiration by removing and replacing layers of clothing.
Socks should be changed whenever the feet become moist or wet.
Clothing and equipment should be properly fitted to avoid any
interference with blood circulation. Improper blood circulation reduces
the amount of heat that reaches the extremities. Tight fitting socks,
shoes, and hand wear are especially hazardous in very cold climates. The
face needs extra protection against high winds, and the ears need
massaging from time to time to maintain circulation. Hands may be used
to massage and warm the face. By using the buddy system, individuals
can watch each other’s face for signs of frostbite to detect it early and
keep tissue damage to a minimum. A mask or headgear tunneled in front
of the face guards against direct wind injury. Fingers and toes should be
exercised to keep them warm and to detect any numbness. Wearing
windproof leather gloves or mittens and avoiding kerosene, gasoline, or
alcohol on the skin are also preventive measures. Cold metal should not
be touched with bare skin; doing so could result in severe skin damage.
o Adequate clothing and shelter are also
necessary during periods of inactivity.

FM 21-11
(4) Snow blindness. Snow blindness is the effect that glare
from an ice field or snowfield has on the eyes. It is more likely to occur in
hazy, cloudy weather than when the sun is shining. Glare from the sun
will cause an individual to instinctively protect his eyes. However, in
cloudy weather, he may be overconfident and expose his eyes longer than
when the threat is more obvious. He may also neglect precautions such as
the use of protective eyewear. Waiting until discomfort (pain) is felt
before using protective eyewear is dangerous because a deep burn of the
eyes may already have occurred.
Signs/Symptoms. Symptoms of snow blindness are
a sensation of grit in the eyes with pain in and over the eyes, made worse
by eyeball movement. Other signs/symptoms are watering, redness,
headache, and increased pain on exposure to light. The same condition
that causes snow blindness can cause snowburn of skin, lips, and eyelids.
If a snowburn is neglected, the result is the same as a sunburn.
Treatment. First aid measures consist of
blindfolding or covering the eyes with a dark cloth which stops painful
eye movement. Complete rest is desirable. If further exposure to light is
not preventable, the eyes should be protected with dark bandages or the
darkest glasses available. Once unprotected exposure to sunlight stops,
the condition usually heals in a few days without permanent damage. The
casualty should be evacuated to the nearest medical facility.
Prevention. Putting on protective eye wear is
essential not only to prevent injury, but to prevent further injury if any
has occurred. When protective eye wear is not available, an emergency
pair can be made from a piece of wood or cardboard cut and shaped to the
width of the face. Cut slits for the eyes and attach strings to hold the
improvised glasses in place. Slits are made at the point of vision to allow
just enough space to see and reduce the risk of injury. Blackening the
eyelids and face around the eyes absorbs some of the harmful rays.
(5) Dehydration. Dehydration occurs when the body loses
too much fluid, salt, and minerals. A certain amount of body fluid is lost
through normal body processes. A normal daily intake of food and liquids
replaces these losses. When individuals are engaged in any strenuous
exercises or activities, an excessive amount of fluid and salt is lost
through sweat. This excessive loss creates an imbalance of fluids, and
dehydration occurs when fluid and salt are not replaced. It is very
important to know that it can be prevented if troops are instructed in its
causes, symptoms, and preventive measures. The danger of dehydration
is as prevalent in cold regions as it is in hot regions. In hot weather the
individual is aware of his body losing fluids and salt. He can see, taste,
and feel the sweat as it runs down his face, gets into his eyes, and on his
lips and tongue, and drips from his body. In cold weather, however, it is
5-15
•
•
•
FM 21-11
extremely difficult to realize that this condition exists. The danger of
dehydration in cold weather operations is a serious problem. In cold
climates, sweat evaporates so rapidly or is absorbed so thoroughly by
layers of heavy clothing that it is rarely visible on the skin. Dehydration
also occurs during cold weather operations because drinking is
inconvenient. Dehydration will weaken or incapacitate a casualty for a
few hours, or sometimes, several days. Because rest is an important part
of the recovery process, casualties must take care that limited movement
during their recuperative period does not enhance the risk of becoming a
cold weather casualty.
Signs/Symptoms. The symptoms of cold weather
dehydration are similar to those encountered in heat exhaustion. The
mouth, tongue, and throat become parched and dry, and swallowing
becomes difficult. The casualty may have nausea with or without
vomiting along with extreme dizziness and fainting. The casualty may
also feel generally tired and weak and may experience muscle cramps
(especially in the legs). Focusing eyes may also become difficult.
Treatment. The casualty should be kept warm and
his clothes should be loosened to allow proper circulation. Shelter from
wind and cold will aid in this treatment. Fluid replacement, rest, and
prompt medical treatment are critical. Medical personnel will determine
the need for salt replacement.
Prevention. These general preventive measures
apply for both hot and cold weather. Sufficient additional liquids should
be consumed to offset excessive body losses of these elements. The
amount should vary according to the individual and the type of work he
is doing (light, heavy, or very strenuous). Rest is equally important as a
preventive measure. Each individual must realize that any work that
must be done while bundled in several layers of clothing is extremely
exhausting. This is especially true of any movement by foot, regardless
of the distance.
(6) Hypothermia (general cooling). In intense cold a soldier
may become both mentally and physically numb, thus neglecting
essential tasks or requiring more time and effort to achieve them. Under
some conditions (particularly cold water immersion), even a soldier in
excellent physical condition may die in a matter of minutes. The
destructive influence of cold on the body is called hypothermia. This
means bodies lose heat faster than they can produce it. Frostbite may
occur without hypothermia when extremities do not receive sufficient
heat from central body stores. The reason for this is inadequate
circulation and/or inadequate insulation. Nonetheless, hypothermia and
frostbite may occur at the same time with exposure to below-freezing
temperatures. An example of this is an avalanche accident. Hypothermia
5-16
•
•
•
C 2, FM 21-11
may occur from exposure to temperatures above freezing, especially from
immersion in cold water, wet-cold conditions, or from the effect of wind.
Physical exhaustion and insufficient food intake may also increase the
risk of hypothermia. Excessive use of alcohol leading to unconsciousness
in a cold environment can also result in hypothermia. General cooling of
the entire body to a temperature below 95°F is caused by continued
exposure to low or rapidly dropping temperatures, cold moisture, snow,
or ice. Fatigue, poor physical condition, dehydration, faulty blood
circulation, alcohol or other drug intoxication, trauma, and immersion
can cause hypothermia. Remember, cold affects the body systems slowly
and almost without notice. Soldiers exposed to low temperatures for
extended periods may suffer ill effects even if they are well protected by
clothing.
Signs/Symptoms. As the body cools, there are
several stages of progressive discomfort and impairment. A
sign/symptom that is noticed immediately is shivering. Shivering is an
attempt by the body to generate heat. The pulse is faint or very difficult
to detect. People with temperatures around 90°F may be drowsy and
mentally slow. Their ability to move may be hampered, stiff, and
uncoordinated, but they may be able to function minimally. Their speech
may be slurred. As the body temperature drops further, shock becomes
evident as the person’s eyes assume a glassy state, breathing becomes
slow and shallow, and the pulse becomes weaker or absent. The person
becomes very stiff and uncoordinated. Unconsciousness may follow
quickly. As the body temperature drops even lower, the extremities
freeze, and a deep (or core) body temperature (below 85°F) increases the
risk of irregular heart action. This irregular heart action or heart
standstill can result in sudden death.
Treatment. Except in cases of the most severe
hypothermia (marked by coma or unconsciousness, a weak pulse, and a
body temperature of approximately 90°F or below), the treatment for
hypothermia is directed towards rewarming the body evenly and without
delay. Provide heat by using a hot water bottle, electric blanket,
campfire, or another soldier’s body heat. Always call or send for help as
soon as possible and protect the casualty immediately with dry clothing
or a sleeping bag. Then, move him to a warm place. Evaluate other
injuries and treat them. Treatment can be given while the casualty is
waiting evacuation or while he is en route. In the case of an accidental
breakthrough into ice water, or other hypothermic accident, strip the
casualty of wet clothing immediately and bundle him into a sleeping bag.
Mouth-to-mouth resuscitation should be started at once if the casualty’s
breathing has stopped or is irregular or shallow. Warm liquids may be
given gradually but must not be forced on an unconscious or
semiconscious person because he may choke. The casualty should be
transported on a litter because the exertion of walking may aggravate
5-17
•
•
C 2, FM 21-11
circulation problems. A physician should immediately treat any
hypothermia casualty. Hypothermia is life-threatening until normal body
temperature has been restored. The treatment of a casualty with severe
hypothermia is based upon the following principles: stabilize the
temperature, attempt to avoid further heat loss, handle the casualty
gently, and evacuate as soon as possible to the nearest medical treatment
facility! Rewarming a severely hypothermic casualty is extremely
dangerous in the field due to the great possibility of such complications
as rewarming shock and disturbances in the rhythm of the heartbeat.
H CAUTION
Hypothermia is a MEDICAL EMERGENCY!
Prompt medical treatment is necessary.
Casualties with hypothermic complications
should be transported to a medical treatment
facility immediately.
CAUTION
The casualty is unable to generate his own
body heat. Therefore, merely placing him in a
blanket or sleeping bag is not sufficient.
Prevention. Prevention of hypothermia consists of
all actions that will avoid rapid and uncontrollable loss of body heat.
Individuals should be properly equipped and properly dressed (as
appropriate for conditions and exposure). Proper diet, sufficient rest, and
general principles apply. Ice thickness must be tested before river or lake
crossings. Anyone departing a fixed base by aircraft, ground vehicle, or
foot must carry sufficient protective clothing and food reserves to
survive during unexpected weather changes or other unforeseen
emergencies. Traveling alone is never safe. Expected itinerary and arrival
time should be left with responsible parties before any departure in
severe weather. Anyone living in cold regions should learn how to build
expedient shelters from available materials including snow.

CHAPTER 6
FIRST AID FOR BITES AND STINGS
INTRODUCTION
Snakebites, insect bites, or stings can cause intense pain and/or swelling.
If not treated promptly and correctly, they can cause serious illness or
death. The severity of a snakebite depends upon: whether the snake is
poisonous or nonpoisonous, the type of snake, the location of the bite,
and the amount of venom injected. Bites from humans and other animals,
such as dogs, cats, bats, raccoons, and rats can cause severe bruises and
infection, and tears or lacerations of tissue. Awareness of the potential
sources of injuries can reduce or prevent them from occurring.
Knowledge and prompt application of first aid measures can lessen the
severity of injuries from bites and stings and keep the soldier from
becoming a serious casualty.
6-1. Types of Snakes
a. Nonpoisonous Snakes. There are approximately 130 different
varieties of nonpoisonous snakes in the United States. They have ovalshaped
heads and round eyes. Unlike poisonous snakes, discussed below,
nonpoisonous snakes do not have fangs with which to inject venom. See
Figure 6-1 for characteristics of a nonpoisonous snake.
b. Poisonous Snakes. Poisonous snakes are found throughout
the world, primarily in tropical to moderate climates. Within the United
States, there are four kinds: rattlesnakes, copperheads, water moccasins
(cottonmouth), and coral snakes. Poisonous snakes in other parts of the
world include sea snakes, the fer-de-lance, the bushmaster, and the
tropical rattlesnake in tropical Central America; the Malayan pit viper in
the tropical Far East; the cobra in Africa and Asia; the mamba (or black
mamba) in Central and Southern Africa; and the krait in India and
Southeast Asia. See Figure 6-2 for characteristics of a poisonous pit
viper.

FM 21-11
(1) Rattlesnakes, bushmasters, copperheads, fer-de-lance,
Malayan pit vipers, and water moccasins (cottonmouth) are called pit
vipers because of the small, deep pits between the nostrils and eyes on
each side of the head (Figure 6-2). In addition to their long, hollow fangs,
these snakes have other identifying features: thick bodies, slit-like pupils
of the eyes, and flat, almost triangular-shaped heads. Color markings and
other identifying characteristics, such as rattles or a noticeable white
interior of the mouth (cottonmouth), also help distinguish these
poisonous snakes. Further identification is provided by examining the
bite pattern of the wound for signs of fang entry. Occasionally there will
be only one fang mark, as in the case of a bite on a finger or toe where
there is no room for both fangs, or when the snake has broken off a fang.
(2) The casualty’s condition provides the best information
about the seriousness of the situation, or how much time has passed since
the bite occurred. Pit viper bites are characterized by severe burning
pain. Discoloration and swelling around the fang marks usually begins
within 5 to 10 minutes after the bite. If only minimal swelling occurs
within 30 minutes, the bite will almost certainly have been from a
nonpoisonous snake or possibly from a poisonous snake which did not
inject venom. The venom destroys blood cells, causing a general
discoloration of the skin. This reaction is followed by blisters and
numbness in the affected area. Other signs which can occur are weakness,
rapid pulse, nausea, shortness of breath, vomiting, and shock.
d. Corals, Cobras, Kraits, and Mambas. Corals, cobra, kraits,
and mambas all belong to the same group even though they are found in
different parts of the world. All four inject their venom through short,
grooved fangs, leaving a characteristic bite pattern. See Figure 6-4 for
illustration of a cobra snake.
6-3
Figure 6-4. Cobra snake.
FM 21-11
(1) The small coral snake, found in the Southeastern United
States, is brightly colored with bands of red, yellow (or almost white), and
black completely encircling the body (Figure 6-5). Other nonpoisonous
snakes have the same coloring, but on the coral snake found in the United
States, the red ring always touches the yellow ring. To know the
difference between a harmless snake and the coral snake found in the
United States, remember the following
“Red on yellow will kill a fellow. Red on black,
venom will lack.”
(2) The venom of corals, cobras, kraits, and mambas
produces symptoms different from those of pit vipers. Because there is
only minimal pain and swelling, many people believe that the bite is not
serious. Delayed reactions in the nervous system normally occur between
1 to 7 hours after the bite. Symptoms include blurred vision, drooping
eyelids, slurred speech, drowsiness, and increased salivation and
sweating. Nausea, vomiting, shock, respiratory difficulty, paralysis,
convulsions, and coma will usually develop if the bite is not treated
promptly.
e. Sea Snakes. Sea snakes (Figure 6-6) are found in the warm
water areas of the Pacific and Indian oceans, along the coasts, and at the
mouths of some larger rivers. Their venom is VERY poisonous, but their
fangs are only 1/4 inch long. The first aid outlined for land snakes also
applies to sea snakes.
6-4
Figure 6-5. Coral snake.
C 2, FM 21-11
6-2. Snakebites
If a soldier should accidentally step on or otherwise disturb a snake, it
will attempt to strike. Chances of this happening while traveling along
trails or waterways are remote if a soldier is alert and careful. Poisonous
snakes DO NOT always inject venom when they bite or strike a person.
However, all snakes may carry tetanus (lockjaw); anyone bitten by a
snake, whether poisonous or nonpoisonous, should immediately seek
medical attention. Poison is injected from the venom sacs through
grooved or hollow fangs. Depending on the species, these fangs are either
long or short. Pit vipers have long hollow fangs. These fangs are folded
against the roof of the mouth and extend when the snake strikes. This
allows them to strike quickly and then withdraw. Cobras, coral snakes,
kraits, mambas, and sea snakes have short, grooved fangs. These snakes
are less effective in their attempts to bite, since they must chew after
striking to inject enough venom (poison) to be effective. See Figure 6-7
for characteristics of a poisonous snakebite. In the event you are bitten,
attempt to identify and/or kill the snake. Take it to medical personnel for
inspection/identification. This provides valuable information to medical
personnel who deal with snakebites. TREAT ALL SNAKEBITES AS
POISONOUS.

C 2, FM 21-11
a. Venoms. The venoms of different snakes cause different
effects. Pit viper venoms (hemotoxins) destroy tissue and blood cells.
Cobras, adders, and coral snakes inject powerful venoms (neurotoxins)
which affect the central nervous system, causing respiratory paralysis.
Water moccasins and sea snakes have venom that is both hemotoxic and
neurotoxic.
b. Identification. The identification of poisonous snakes is very
important since medical treatment will be different for each type of
venom. Unless it can be positively identified the snake should be killed
and saved. When this is not possible or when doing so is a serious threat
to others, identification may sometimes be difficult since many
venomous snakes resemble harmless varieties. When dealing with
snakebite problems in foreign countries, seek advice, professional or
otherwise, which may help identify species in the particular area of
operations.
H c. First Aid. Get the casualty to a medical treatment facility as
soon as possible and with minimum movement. Until evacuation or
treatment is possible, have the casualty lie quietly and not move any
more than necessary. The casualty should not smoke, eat, nor drink any
fluids. If the casualty has been bitten on an extremity, DO NOT elevate
the limb; keep the extremity level with the body. Keep the casualty
comfortable and reassure him. If the casualty is alone when bitten, he
should go to the medical facility himself rather than wait for someone to
find him. Unless the snake has been positively identified, attempt to kill
it and send it with the casualty. Be sure that retrieving the snake does
not endanger anyone or delay transporting the casualty.
H (1) If the bite is on an arm or leg, place a constricting band
(narrow cravat [swathe], or narrow gauze bandage) one to two finger
widths above and below the bite (Figure 6-8). However, if only one
constricting band is available, place that band on the extremity between
the bite site and the casualty’s heart. If the bite is on the hand or foot,
place a single band above the wrist or ankle. The band should be tight
enough to stop the flow of blood near the skin, but not tight enough to
interfere with circulation. In other words, it should not have a tourniquetlike
affect. If no swelling is seen, place the bands about one inch from
either side of the bite. If swelling is present, put the bands on the
unswollen part at the edge of the swelling. If the swelling extends beyond
the band, move the band to the new edge of the swelling. (If possible,
leave the old band on, place a new one at the new edge of the swelling, and
then remove and save the old one in case the process has to be repeated.)
If possible, place an ice bag over the area of the bite. DO NOT wrap the
limb in ice or put ice directly on the skin. Cool the bite area—do not freeze
it. DO NOT stop to look for ice if it will delay evacuation and medical
treatment.
6-6
FM 21-11
CAUTION
DO NOT attempt to cut open the bite nor suck
out the venom. If the venom should seep
through any damaged or lacerated tissues in
your mouth, you could immediately lose
consciousness or even die.
(2) If the bite is located on an arm or leg, immobilize it at a
level below the heart. DO NOT elevate an arm or leg even with or above
the level of the heart.
CAUTION
When a splint is used to immobilize the arm or
leg, take EXTREME care to ensure the
splinting is done properly and does not bind.
Watch it closely and adjust it if any changes in
swelling occur.
(3) When possible, clean the area of the bite with soap and
water. DO NOT use ointments of any kind.
(4) NEVER give the casualty food, alcohol, stimulants
(coffee or tea), drugs, or tobacco.
(5) Remove rings, watches, or other jewelry from the
affected limb.

FM 21-11
NOTE
It may be possible, in some cases, for an
aidman who is specially trained and is
authorized to carry and use antivenin to
administer it. The use of antivenin presents
special risks, and only those with specialized
training should attempt to use it!
d. Prevention. Except for a few species, snakes tend to be shy or
passive. Unless they are injured, trapped, or disturbed, snakes usually
avoid contact with humans. The harmless species are often more prone to
attack. All species of snakes are usually aggressive during their breeding
season.
(1) Land snakes. Many snakes are active during the period
from twilight to daylight. Avoid walking as much as possible during this
time.
Keep your hands off rock ledges where snakes are
likely to be sunning.
Look around carefully before sitting down,
particularly if in deep grass among rocks.
Attempt to camp on clean, level ground. Avoid
camping near piles of brush, rocks, or other debris.
Sleep on camping cots or anything that will keep
you off the ground. Avoid sleeping on the ground if at all possible.
Check the other side of a large rock before stepping
over it. When looking under any rock, pull it toward you as you turn it
over so that it will shield you in case a snake is beneath it.
Try to walk only in open areas. Avoid walking close
to rock walls or similar areas where snakes may be hiding.
Determine when possible what species of snakes are
likely to be found in an area which you are about to enter.
Hike with another person. Avoid hiking alone in a
snake-infested area. If bitten, it is important to have at least one
companion to perform lifesaving first aid measures and to kill the snake.
Providing the snake to medical personnel will facilitate both
identification and treatment.

FM 21-11
Handle freshly killed venomous snakes only with a
long tool or stick. Snakes can inflict fatal bites by reflex action even after
death.
Wear heavy boots and clothing for some protection
from snakebite. Keep this in mind when exposed to hazardous conditions.
Eliminate conditions under which snakes thrive:
brush, piles of trash, rocks, or logs and dense undergrowth. Controlling
their food (rodents, small animals) as much as possible is also good
prevention.
(2) Sea snakes. Sea snakes may be seen in large numbers
but are not known to bite unless handled. Be aware of the areas where
they are most likely to appear and be especially alert when swimming in
these areas. Avoid swimming alone whenever possible.
WARNING
All species of snakes can swim. Many can
remain under water for long periods. A bite
sustained in water is just as dangerous as one
on land.
6-3. Human and Other Animal Bites
Human or other land animal bites may cause lacerations or bruises. In
addition to damaging tissue, human or bites from animals such as dogs,
cats, bats, raccoons, or rats always present the possibility of infection.
a. Human Bites. Human bites that break the skin may become
seriously infected since the mouth is heavily contaminated with bacteria.
All human bites MUST be treated by medical personnel.
b. Animal Bites. Land animal bites can result in both infection
and disease. Tetanus, rabies, and various types of fevers can follow an
untreated animal bite. Because of these possible complications, the
animal causing the bite should, if possible, be captured or killed (without
damaging its head) so that competent authorities can identify and test
the animal to determine if it is carrying diseases.
c. First Aid.
(1) Cleanse the wound thoroughly with soap or detergent
solution.
6-9
•
•
•
FM 21-11
(2) Flush it well with water.
(3) Cover it with a sterile dressing.
(4) Immobilize an injured arm or leg.
(5) Transport the casualty immediately to a medical
treatment facility.
NOTE
If unable to capture or kill the animal, provide
medical personnel with any information
possible that will help identify it. Information
of this type will aid in appropriate treatment.
6-4. Marine (Sea) Animals
With the exception of sharks and barracuda, most marine animals will
not deliberately attack. The most frequent injuries from marine animals
are wounds by biting, stinging, or puncturing. Wounds inflicted by
marine animals can be very painful, but are rarely fatal.
a. Sharks, Barracuda, and Alligators. Wounds from these
marine animals can involve major trauma as a result of bites and
lacerations. Bites from large marine animals are potentially the most life
threatening of all injuries from marine animals. Major wounds from these
animals can be treated by controlling the bleeding, preventing shock,
giving basic life support, splinting the injury, and by securing prompt
medical aid.
b. Turtles, Moray Eels, and Corals. These animals normally
inflict minor wounds. Treat by cleansing the wound(s) thoroughly and by
splinting if necessary.
c. Jellyfish, Portuguese men-of-war, Anemones, and Others.
This group of marine animals inflict injury by means of stinging cells in
their tentacles. Contact with the tentacles produces burning pain with a
rash and small hemorrhages on the skin. Shock, muscular cramping,
nausea, vomiting, and respiratory distress may also occur. Gently
remove the clinging tentacles with a towel and wash or treat the area.
Use diluted ammonia or alcohol, meat tenderizer, and talcum powder. If
symptoms become severe or persist, seek medical aid.
d. Spiny Fish, Urchins, Stingrays, and Cone Shells. These
animals inject their venom by puncturing with their spines. General
6-10
FM 21-11
signs and symptoms include swelling, nausea, vomiting, generalized
cramps, diarrhea, muscular paralysis, and shock. Deaths are rare.
Treatment consists of soaking the wounds in hot water (when available)
for 30 to 60 minutes. This inactivates the heat sensitive toxin. In
addition, further first aid measures (controlling bleeding, applying a
dressing, and so forth) should be carried out as necessary.
CAUTION
Be careful not to scald the casualty with water
that is too hot because the pain of the wound
will mask the normal reaction to heat.
6-5. Insect Bites/Stings
An insect bite or sting can cause great pain, allergic reaction,
inflammation, and infection. If not treated correctly, some bites/stings
may cause serious illness or even death. When an allergic reaction is not
involved, first aid is a simple process. In any case, medical personnel
should examine the casualty at the earliest possible time. It is important
to properly identify the spider, bee, or creature that caused the bite/sting,
especially in cases of allergic reaction when death is a possibility.
a. Types of Insects. The insects found throughout the world
that can produce a bite or sting are too numerous to mention in detail.
Commonly encountered stinging or biting insects include brown recluse
spiders (Figure 6-9), black widow spiders (Figure 6-10), tarantulas (Figure
6-11), scorpions (Figure 6-12), urticating caterpillars, bees, wasps,
centipedes, conenose beetles (kissing bugs), ants, and wheel bugs. Upon
being reassigned, especially to overseas areas, take the time to become
acquainted with the types of insects to avoid.
6-11
Figure 6-9. Brown recluse spider.
FM 21-11
b. Signs/Symptoms. Discussed in paragraphs (1) and (2) below
are the most common effects of insect bites/stings. They can occur alone
or in combination with the others.
(1) Less serious. Commonly seen signs/symptoms are pain,
irritation, swelling, heat, redness, and itching. Hives or wheals (raised

Figure 6-12. Scorpion.
C 2, FM 21-11
areas of the skin that itch) may occur. These are the least severe of the
allergic reactions that commonly occur from insect bites/stings. They are
usually dangerous only if they affect the air passages (mouth, throat,
nose, and so forth), which could interfere with breathing. The bites/stings
of bees, wasps, ants, mosquitoes, fleas, and ticks are usually not serious
and normally produce mild and localized symptoms. A tarantula’s bite is
usually no worse than that of a bee sting. Scorpions are rare and their
stings (except for a specific species found only in the Southwest desert)
are painful but usually not dangerous.
(2) Serious. Emergency allergic or hypersensitive reactions
sometimes result from the stings of bees, wasps, and ants. Many people
are allergic to the venom of these particular insects. Bites or stings from
these insects may produce more serious reactions, to include generalized
itching and hives, weakness, anxiety, headache, breathing difficulties,
nausea, vomiting, and diarrhea. Very serious allergic reactions (called
anaphylactic shock) can lead to complete collapse, shock, and even death.
Spider bites (particularly from the black widow and brown recluse
spiders) can be serious also. Venom from the black widow spider affects
the nervous system. This venom can cause muscle cramps, a rigid,
nontender abdomen, breathing difficulties, sweating, nausea and
vomiting. The brown recluse spider generally produces local rather than
system-wide problems; however, local tissue damage around the bite can
be severe and can lead to an ulcer and even gangrene.
c. First Aid. There are certain principles that apply regardless
of what caused the bite/sting. Some of these are:
If there is a stinger present, for example, from a bee,
remove the stinger by scraping the skin’s surface with a fingernail or
knife. DO NOT squeeze the sac attached to the stinger because it may
inject more venom.
Wash the area of the bite/sting with soap and water
(alcohol or an antiseptic may also be used) to help reduce the chances of
an infection and remove traces of venom.
Remove jewelry from bitten extremities because swelling
is common and may occur.
In most cases of insect bites the reaction will be mild and
localized use ice or cold compresses (if available) on the site of the
bite/sting. This will help reduce swelling, ease the pain, and slow the
absorption of venom. Meat tenderizer (to neutralize the venom) or
calamine lotion (to reduce itching) may be applied locally. If necessary,
seek medical aid.
6-13
•
•
•
•
C 2, FM 21-11
In more serious reactions (severe and rapid swelling,
allergic symptoms, and so forth) treat the bite/sting like you would treat
a snakebite; that is, apply constricting bands above and below the site.
See paragraph 6-2c(1) above for details and illustration (Figure 6-8) of a
constricting band.
H Be prepared to perform basic lifesaving measures, such
as rescue breathing.
Reassure the casualty and keep him calm.
In serious reactions, attempt to capture the insect for
positive identification; however, be careful not to become a casualty
yourself.
If the reaction or symptoms appear serious, seek
medical aid immediately.
H CAUTION
Insect bites/stings may cause anaphylactic
shock (a shock caused by a severe allergic
reaction). This is a life-threatening event and a
MEDICAL EMERGENCY! Be prepared to
immediately transport the casualty to a
medical facility.
NOTE
Be aware that some allergic or hypersensitive
individuals may carry identification (such as a
MEDIC ALERT tag) or emergency insect bite
treatment kits. If the casualty is having an
allergic reaction and has such a kit, administer
the medication in the kit according to the
instructions which accompany the kit.
d. Prevention. Some prevention principles are:
Apply insect repellent to all exposed skin, such as the
ankles to prevent insects from creeping between uniform and boots. Also
6-14
•
•
•
•
•
•
C 2, FM 21-11
apply the insect repellent to the shoulder blades where the shirt fits tight
enough that mosquitoes bite through. DO NOT apply insect repellent to
the eyes.
Reapply repellent, every 2 hours during strenuous
activity and soon after stream crossings.
Blouse the uniform inside the boots to further reduce
risk.
Wash yourself daily if the tactical situation permits. Pay
particular attention to the groin and armpits.
Use the buddy system. Check each other for insect bites.
Wash your uniform at least weekly.

CHAPTER 7
FIRST AID IN TOXIC ENVIRONMENTS
INTRODUCTION
American forces have not been exposed to high levels of toxic substances
on the battlefield since World War I. In future conflicts and wars we can
expect the use of such agents. Chemical weapons will degrade unit
effectiveness rapidly by forcing troops to wear hot protective clothing
and by creating confusion and fear. Through training in protective
procedures and first aid, units can maintain their effectiveness on the
integrated battlefield.
Section I. INDIVIDUAL PROTECTION AND FIRST AID
EQUIPMENT FOR TOXIC SUBSTANCES
7-1. Toxic Substances
a. Gasoline, chlorine, and pesticides are examples of common
toxic substances. They may exist as solids, liquids, or gases depending
upon temperature and pressure. Gasoline, for example, is a vaporizable
liquid; chlorine is a gas; and Warfarin, a pesticide, is a solid. Some
substances are more injurious to the body than others when they are
inhaled or eaten or when they contact the skin or eyes. Whether they are
solids, liquids, or gases (vapors and aerosols included), they may irritate,
inflame, blister, burn, freeze, or destroy tissue such as that associated
with the respiratory tract or the eyes. They may also be absorbed into the
bloodstream, disturbing one or several of the body’s major functions.
b. You may come in contact with toxic substances in combat or
in everyday activities. Ordinarily, brief exposures to common household
toxic substances, such as disinfectants and bleach solutions, do not cause
injuries. Exposure to toxic chemical agents in warfare, even for a few
seconds, could result in death, injury, or incapacitation. Remember that
toxic substances employed by an enemy could persist for hours or days.
To survive and operate effectively in a toxic environment, you must be
prepared to protect yourself from the effects of chemical agents and to
provide first aid to yourself and to others.
7-2. Protective and First Aid Equipment
You are issued equipment for protection and first aid treatment in a toxic
environment. You must know how to use the items described in a through
e. It is equally important that you know when to use them. Use your
protective clothing and equipment when you are ordered to and when you

are under a nuclear, biological, or chemical (NBC) attack. Also, use your
protective clothing and equipment when you enter an area where NBC
agents have been employed.
a. Field Protective Mask With Protective Hood. Your field
protective mask is the most important piece of protective equipment.
You are given special training in its use and care.
b. Field Protective Clothing. Each soldier is authorized three
sets of the following field protective clothing:
Overgarment ensemble (shirt and trousers), chemical
protective.
Footwear cover (overboots), chemical protective.
Glove set, chemical protective.
c. Nerve Agent Pyridostigmine Pretreatment (NAPP). You will
be issued a blister pack of pretreatment tablets when your commander
directs. When ordered to take the pretreatment you must take one tablet
every eight hours. This must be taken prior to exposure to nerve agents,
since it may take several hours to develop adequate blood levels.
NOTE
Normally, one set of protective clothing is used
in acclimatization training that uses various
mission-oriented protective posture (MOPP)
levels.
d. M258A1 Skin Decontamination Kit. The M258A1 Skin
Decontamination (decon) Kit contains three each of the following:
DECON-1 packets containing wipes (pads) moistened
with decon solution.
DECON-2 packets containing dry wipes (pads)
previously moistened with decon solution and sealed glass ampules.
Ampules are crushed to moisten pads.

WARNING
The decon solution contained in both
DECON-1 and DECON-2 packets is a poison
and caustic hazard and can permanently
damage the eyes. Keep wipes out of the eyes,
mouth, and open wounds. Use WATER to
wash toxic agent out of eyes and wounds and
seek medical aid.
e. Nerve Agent Antidote Kit, Mark I (NAAK MKI). Each
soldier is authorized to carry three Nerve Agent Antidote Kits, Mark I,
to treat nerve agent poisoning. When NAPP has been taken several
hours (but no greater than 8 hours) prior to exposure, the NAAK MKI
treatment of nerve agent poisoning is much more effective.
Section II. CHEMICAL-BIOLOGICAL AGENTS
7-3. Classification
a. Chemical agents may be classified according to the primary
physiological effects they produce, such as nerve, blister, blood, choking,
vomiting, and incapacitating agents.
b. Biological agents may be classified according to the effect
they have on man. These include blockers, inhibitors, hybrids, and
membrane active compounds. These agents are found in living organisms
such as fungi, bacteria and viruses.
WARNING
Ingesting water or food contaminated with
nerve, blister, and other chemical agents and
with some biological agents can be fatal.
NEVER consume water or food which is
suspected of being contaminated until it has
been tested and found safe for consumption.
7-3
FM 21-11
7-4. Conditions for Masking Without Order or Alarm
Once an attack with a chemical or biological agent is detected or
suspected, or information is available that such an agent is about to be
used, you must STOP breathing and mask immediately. DO NOT WAIT
to receive an order or alarm under the following circumstances:

7-5. First Aid for a Chemical Attack (081-831-1030 and
081-831-1031)
Your field protective mask gives protection against chemical as well as
biological agents. Previous practice enables you to mask in 9 seconds or
less or to put on your mask with hood within 15 seconds.
a. Step ONE (081-831-1030 and 081-831-1031). Stop
breathing. Don your mask, seat it properly, clear and check your mask,
and resume breathing. Give the alarm, and continue the mission. Keep
your mask on until the “all clear” signal has been given.
NOTE
Keep your mask on until the area is no longer
hazardous and you are told to unmask.
b. Step TWO (081-831-1030). If symptoms of nerve agent
poisoning (paragraph 7-7) appear, immediately give yourself a nerve
agent antidote. You should have taken NAPP several hours prior to
exposure which will enhance the action of the nerve agent antidote.
CAUTION
Do not inject a nerve agent antidote until you
are sure you need it.
c. Step THREE (081-831-1031). If your eyes and face become
contaminated, you must immediately try to get under cover. You need
this shelter to prevent further contamination while performing decon
procedures on areas of the head. If no overhead cover is available, throw
your poncho or shelter half over your head before beginning the decon

process. Then you should put on the remaining protective clothing. (See
Appendix F for decon procedure.) If vomiting occurs, the mask should be
lifted momentarily and drained—while the eyes are closed and the breath
is held—and replaced, cleared, and sealed.
d. Step FOUR. If nerve agents are used, mission p.ermitting,
watch for persons needing nerve agent antidotes and immediately follow
procedures outlined in paragraph 7-8 b.
e. STEP FIVE. When your mission permits, decon your
clothing and equipment.
Section III. NERVE AGENTS
7-6. Background Information
a. Nerve agents are among the deadliest of chemical agents.
They can be delivered by artillery shell, mortar shell, rocket, missile,
landmine, and aircraft bomb, spray, or bomblet. Nerve agents enter the
body by inhalation, by ingestion, and through the skin. Depending on the
route of entry and the amount, nerve agents can produce injury or death
within minutes. Nerve agents also can achieve their effects with small
amounts. Nerve agents are absorbed rapidly, and the effects are felt
immediately upon entry into the body. You will be issued three Nerve
Agent Antidote Kits, Mark I. Each kit consists of one atropine
autoinjector and one pralidoxime chloride (2 PAM Cl) autoinjector (also
called injectors) (Figure 7-1).

b. When you have the signs and symptoms of nerve agent
poisoning, you should immediately put on the protective mask and then
inject yourself with one set of the Nerve Agent Antidote Kit, Mark I.
You should inject yourself in the outside (lateral) thigh muscle or if you
are thin, in the upper outer (lateral) part of the buttocks.
c. Also, you may come upon an unconscious chemical agent
casualty who will be unable to care for himself and who will require your
aid. You should be able to successfully—
(1) Mask him if he is unmasked.
(2) Inject him, if necessary, with all his autoinjectors.
(3) Decontaminate his skin.
(4) Seek medical aid.
7-7. Signs/Symptoms of Nerve Agent Poisoning (081-831-1030
and 081-831-1031)
The symptoms of nerve agent poisoning are grouped as MILD—those
which you recognize and for which you can perform self-aid, and
SEVERE—those which require buddy aid.
a. MILD Symptoms (081-831-1030).
Unexplained runny nose.
Unexplained sudden headache.
Sudden drooling.
Difficulty seeing (blurred vision).

7-8. First Aid for Nerve Agent Poisoning (081-831-1030) and
(081-831-1031)
The injection site for administering the Nerve Agent Antidote Kit, Mark
I (see Figure 7-1), is normally in the outer thigh muscle (see Figure 7-2). It
is important that the injections be given into a large muscle area. If the
individual is thinly-built, then the injections must be administered into
the upper outer quarter (quadrant) of the buttocks (see Figure 7-3). This
avoids injury to the thigh bone.

(9) Apply firm, even pressure (not a jabbing motion) to the
injector until it pushes the needle into your thigh (or buttocks).
WARNING
Using a jabbing motion may result in an
improper injection or injury to the thigh or
buttocks.
NOTE
Firm pressure automatically triggers the
coiled spring mechanism. This plunges the
needle through the clothing into the muscle
and injects the fluid into the muscle tissue.

FM 21-11
(10) Hold the injector firmly in place for at least ten seconds.
The ten seconds can be estimated by counting “one thousand and one,
one thousand and two,” and so forth.
(11) Carefully remove the autoinjector.
(12) Place the used atropine injector between the little finger
and the ring finger of the hand holding the remaining autoinjector and
the clip (see Figure 7-9). WATCH OUT FOR THE NEEDLE!
(13) Pull the 2 PAM C1 autoinjector (the larger of the two
injectors) out of the clip (see Figure 7-10) and inject yourself in the same
manner as steps (7) through (11) above, holding the black (needle) end

needles.
(a) Push the needle of each injector (one at a time)
through one of the pocket flaps of your protective overgarment.
(b) Bend each needle to form a hook.
WARNING
It is important to keep track of all used
autoinjectors so that medical personnel can
determine how much antidote has been given
and the proper follow-up treatment can be
provided, if needed.

WARNING
If within 5 to 10 minutes after administering
the first set of injections, your heart begins to
beat rapidly and your mouth becomes very
dry, DO NOT give yourself another set of
injections. You have already received enough
antidote to overcome the dangerous effects of
the nerve agent. If you are able to walk
without assistance (ambulate), know who you
are and where you are, you WILL NOT need
the second set of injections. (If not needed,
giving yourself a second set of injections may
create a nerve agent antidote overdose, which
could cause incapacitation.) If, however, you
continue to have symptoms of nerve agent
poisoning for 10 to 15 minutes after receiving
one set of injections, seek a buddy to check
your symptoms. If your buddy agrees that
your symptoms are worsening, administer the
second set of injections.
NOTE (081-831-1030)
While waiting between sets (injections), you
should decon your skin, if necessary, and put
on the remaining protective clothing.
b. Buddy aid (081-831-1031).
A soldier exhibiting SEVERE signs/symptoms of nerve agent poisoning
will not be able to care for himself and must therefore be given buddy aid
as quickly as possible. Buddy aid will be required when a soldier is totally
and immediately incapacitated prior to being able to apply self-aid, and
all three sets of his Nerve Agent Antidote Kit, Mark I, need to be given
by a buddy. Buddy aid may also be required after a soldier attempted to
counter the nerve agent by self-aid but became incapacitated after giving
himself one set of the autoinjectors. Before initiating buddy aid, a buddy
should determine if one set of injectors has already been used so that no
more than three sets of the antidote are administered.
(1) Move (roll) the casualty onto his back (face up) if not
already in that position.
7-15
FM 21-11
WARNING
Avoid unnecessary movement of the casualty so
as to keep from spreading the contamination.
(2) Remove the casualty’s protective mask from the carrier.
(3) Position yourself above the casualty’s head, facing his feet.
WARNING
Squat, DO NOT kneel, when masking a
chemical agent casualty. Kneeling may force
the chemical agent into or through your
protective clothing, which will greatly reduce
the effectiveness of the clothing.
(4) Place the protective mask on the casualty.
(5) Have the casualty clear the mask.
(6) Check for a complete mask seal by covering the inlet
valves. If properly sealed the mask will collapse.
NOTE
If the casualty is unable to follow instructions,
is unconscious, or is not breathing, he will not
be able to perform steps (5) or (6). It may,
therefore, be impossible to determine if the
mask is sealed. But you should still try to
check for a good seal by placing your hands
over the valves.
(7) Pull the protective hood over the head, neck, and
shoulders of the casualty.
(8) Position yourself near the casualty’s thigh.
(9) Remove one set of the casualty’s autoinjectors.

Section IV. OTHER AGENTS
7-9. Blister Agents
Blister agents (vesicants) include mustard (HD), nitrogen mustards
(HN), lewisite (L), and other arsenicals, mixtures of mustards and
arsenical, and phosgene oxime (CX). Blister agents act on the eyes,
mucous membranes, lungs, and skin. They burn and blister the skin or
any other body parts they contact. Even relatively low doses may cause
serious injury. Blister agents damage the respiratory tract (nose, sinuses
and windpipe) when inhaled and cause vomiting and diarrhea when
absorbed. Lewisite and phosgene oxime cause immediate pain on contact.
However, mustard agents are deceptive and there is little or no pain at
the time of exposure. Thus, in some cases, signs of injury may not appear
for several hours after exposure.
a. Protective Measures. Your protective mask with hood and
protective overgarments provide you protection against blister agents. If
it is known or suspected that blister agents are being used, STOP
BREATHING, put on your mask and all your protective overgarments.
7-21
Figure 7-14. Three sets of used autoinjectors attached to pocket flap.
FM 21-11
CAUTION
Large drops of liquid vesicants on the
protective overgarment ensemble may
penetrate it if allowed to stand for an extended
period. Remove large drops as soon as possible.
b. Signs/Symptoms of Blister Agent Poisoning.
(1) Immediate and intense pain upon contact (lewisite and
phosgene oxime). No initial pain upon contact with mustard.
(2) Inflammation and blisters (burns)–tissue destruction.
The severity of a chemical burn is directly related to the concentration of
the agent and the duration of contact with the skin. The longer the agent
is in contact with the tissue, the more serious the injury will be.
(3) Vomiting and diarrhea. Exposure to high concentrations of
vesicants may cause vomiting anchor diarrhea.
(4) Death. The blister agent vapors absorbed during
ordinary field exposure will probably not cause enough internal body
(systemic) damage to result in death. However, death may occur from
prolonged exposure to high concentrations of vapor or from extensive
liquid contamination over wide areas of the skin, particularly when decon
is neglected or delayed.
c. First Aid Measures.
(1) Use your M258A1 decon kit to decon your skin and use
water to flush contaminated eyes. Decontamination of vesicants must be
done immediately (within 1 minute is best).
(2) If blisters form, cover them loosely with a field dressing
and secure the dressing.
CAUTION
Blisters are actually burns. DO NOT attempt
to decon the skin where blisters have formed.
(3) If you receive blisters over a wide area of the body, you are
considered seriously burned. SEEK MEDICAL AID IMMEDIATELY.
7-22
FM 21-11
(4) If vomiting occurs, the mask should be lifted
momentarily and drained—while the eyes are closed and the breath is
held–and replaced, cleared, and sealed.
(5) Remember, if vomiting or diarrhea occurs after having
been exposed to blister agents, SEEK MEDICAL AID IMMEDIATELY.
7-10. Choking Agents (Lung-Damaging Agents)
Chemical agents that attack lung tissue, primarily causing fluid buildup
(pulmonary edema), are classified as choking agents (lung-damaging
agents). This group includes phosgene (CG), diaphosgene (DP), chlorine
(CL), and chloropicrin (PS). Of these four agents, phosgene is the most
dangerous and is more likely to be employed by the enemy in future
conflict.
a. Protective Measures. Your protective mask gives adequate
protection against choking agents.
b. Signs/Symptoms. During and immediately after exposure to
choking agents (depending on agent concentration and length of
exposure), you may experience some or all of the following
signs/symptoms:
Tears (lacrimation).
Dry throat.
Coughing.
Choking.
Tightness of chest.
Nausea and vomiting.
Headaches.
c. First Aid Measures.
(1) If you come in contact with phosgene, your eyes become
irritated, or a cigarette becomes tasteless or offensive, STOP
BREATHING and put on your mask immediately.

(2) If vomiting occurs, the mask should be lifted
momentarily and drained—while the eyes are closed and the breath is
held–replaced, cleared, and sealed.
(3) Seek medical assistance if any of the above
signs/symptoms occur.
NOTE
If you have no difficulty breathing, do not feel
nauseated, and have no more than the usual
shortness of breath on exertion, then you
inhaled only a minimum amount of the agent.
You may continue normal duties.
d. Death. With ordinary field exposure to choking agents, death
will probably not occur. However, prolonged exposure to high
concentrations of the vapor and neglect or delay in masking can be fatal.
7-11. Blood Agents
Blood agents interfere with proper oxygen utilization in the body.
Hydrogen cyanide (AC) and cyanogen chloride (CK) are the primary
agents in this group.
a. Protective Measures. Your protective mask with a fresh
filter gives adequate protection against field concentrations of blood
agent vapor. The protective overgarment as well as the mask are needed
when exposed to liquid hydrogen cyanide.
b. Signs/Symptoms. During and immediately after exposure to
blood agents (depending on agent concentration and length of exposure),
you may experience some or all of the following signs/symptoms:
Eye irritation.
Nose and throat irritation.
Sudden stimulation of breathing.
Nausea.
Coughing.
Tightness of chest.
7-24

Headache.
Unconsciousness.
c. First Aid Measures.
(1) Hydrogen cyanide. During any chemical attack, if you
get a sudden stimulation of breathing or notice an odor like bitter
almonds, PUT ON YOUR MASK IMMEDIATELY. Speed is absolutely
essential since this agent acts so rapidly that within a few seconds its
effects will make it impossible for individuals to put on their mask by
themselves. Stop breathing until the mask is on, if at all possible. This
may be very difficult since the agent strongly stimulates respiration.
(2) Cyanogen chloride. PUT ON YOUR MASK
IMMEDIATELY if you experience any irritation of the eyes, nose, or throat.
d. Medical Assistance. If you suspect that you have been
exposed to blood agents, seek medical assistance immediately.
7-12. Incapacitating Agents
Generally speaking, an incapacitating agent is any compound which can
interfere with your performance. The agent affects the central nervous
system and produces muscular weakness and abnormal behavior. It is
likely that such agents will be disseminated by smoke-producing
munitions or aerosols, thus making breathing their means of entry into
the body. The protective mask is, therefore, essential.
a. There is no special first aid to relieve the symptoms of
incapacitating agents. Supportive first aid and physical restraint may be
indicated. If the casualty is stuporous or comatose, be sure that
respiration is unobstructed; then turn him on his stomach with his head
to one side (in case vomiting should occur). Complete cleansing of the
skin with soap and water should be done as soon as possible; or, the
M258A1 Skin Decontamination Kit can be used if washing is impossible.
Remove weapons and other potentially harmful items from the
possession of individuals who are suspected of having these symptoms.
Harmful items include cigarettes, matches, medications, and small items
which might be swallowed accidentally. Delirious persons have been
known to attempt to eat items bearing only a superficial resemblance to
food.
b. Anticholinergic drugs (BZ - type) may produce alarming
dryness and coating of the lips and tongue; however, there is usually no
danger of immediate dehydration. Fluids should be given sparingly, if at

all, because of the danger of vomiting and because of the likelihood of
temporary urinary retention due to paralysis of bladder muscles. An
important medical consideration is the possibility of heatstroke caused
by the stoppage of sweating. If the environmental temperature is above
78° F, and the situation permits, remove excessive clothing from the
casualty and dampen him to allow evaporative cooling and to prevent
dehydration. If he does not readily improve, apply first aid measures for
heatstroke and seek medical attention.
7-13. Incendiaries
Incendiaries can be grouped as white phosphorus, thickened fuel, metal,
and oil and metal. You must learn to protect yourself against these
incendiaries.
a. White phosphorus (WP) is used primarily as a smoke
producer but can be used for its incendiary effect to ignite field
expedients and combustible materials. The burns from WP are usually
multiple, deep, and variable in size. When particles of WP get on the skin
or clothing, they continue to burn until deprived of air. They also have a
tendency to stick to a surface and must be brushed off or picked out.
(1) If burning particles of phosphorus strike and stick to
your clothing, quickly take off the contaminated clothing before the
phosphorus burns through to the skin.
(2) If burning phosphorus strikes your skin, smother the
flame by submerging yourself in water or by dousing the WP with water
from your canteen or any other source. Urine, a wet cloth, or mud can also
be used.
NOTE
Since WP is poisonous to the system, DO NOT
use grease or oil to smother the flame. The WP
will be absorbed into the body with the grease
or oil.
(3) Keep the WP particles covered with wet material to
exclude air until you can remove them or get them removed from your
skin.
(4) Remove the WP particles from the skin by brushing
them with a wet cloth and by picking them out with a knife, bayonet,
stick, or other available object.
7-26
FM 21-11
(5) Report to a medical facility for treatment as soon as
your mission permits.
b. Thickened fuel mixtures (napalm) have a tendency to cling to
clothing and body surfaces, thereby producing prolonged exposure and
severe burns. The first aid for these burns is the same as for other heat
burns. The heat and irritating gases given off by these combustible
mixtures may cause lung damage, which must be treated by a medical
officer.
c. Metal incendiaries pose special problems. Thermite and
thermate particles on the skin should be immediately cooled with water
and then removed. Even though thermate particles have their own
oxygen supply and continue to burn under water, it helps to cool them
with water. The first aid for these burns is the same as for other heat
burns. Particles of magnesium on the skin burn quickly and deeply. Like
other metal incendiaries, they must be removed. Ordinarily, the complete
removal of these particles should be done by trained personnel at a
medical treatment facility, using local anesthesia. Immediate medical
treatment is required.
d. Oil and metal incendiaries have much the same effect on
contact with the skin and clothing as those discussed ( b and c above).
Appropriate first aid measures for burns are described in Chapter 3.
7-14. First Aid for Biological Agents
We are concerned with victims of biological attacks and with treating
symptoms after the soldier becomes ill. However, we are more concerned
with preventive medicine and hygienic measures taken before the attack.
By accomplishing a few simple tasks we can minimize their effects.
a. Immunizations. In the military we are accustomed to keeping
inoculations up to date. To prepare for biological defense, every effort
must be taken to keep immunizations current. Based on enemy
capabilities and the geographic location of our operations, additional
immunizations may be required.
b. Food and Drink. Only approved food and water should be
consumed. In a suspected biological warfare environment, efforts in
monitoring food and water supplies must be increased. Properly treated
water and properly cooked food will destroy most biological agents.
c.

Sanitation Measures.
(1) Maintain high standards of personal hygiene. This will

7-27
FM 21-11
(2) Avoid physical fatigue. Physical fatigue lowers the
body’s resistance to disease. This, of course, is complemented by good
physical fitness.
(3) Stay out of quarantined areas.
(4) Report sickness promptly. This ensures timely medical
treatment and, more importantly, early diagnosis of the disease.
d. Medical Treatment of Casualties. Once a disease is identified,
standard medical treatment commences. This may be in the form of first
aid or treatment at a medical facility, depending on the seriousness of the
disease. Epidemics of serious diseases may require augmentation of field
medical facilities.
7-15. Toxins
Toxins are alleged to have been used in recent conflicts. Witnesses and
victims have described the agent as toxic rain (or yellow rain) because it
was reported to have been released from aircraft as a yellow powder or
liquid that covered the ground, structures, vegetation, and people.
a. Protective Measures. Individual protective measures
normally associated with persistent chemical agents will provide
protection against toxins. Measures include the use of the protective
mask with hood, and the overgarment ensemble with gloves and
overboots (mission-oriented protective posture level-4 [MOPP 4]).
b. Signs/Symptoms. The occurrence of the symptoms from
toxins may appear in a period of a few minutes to several hours
depending on the particular toxin, the individual susceptibility, and the
amount of toxin inhaled, ingested, or deposited on the skin. Symptoms
from toxins usually involve the nervous system but are often preceded by
less prominent symptoms, such as nausea, vomiting, diarrhea, cramps, or
burning distress of the stomach region. Typical neurological symptoms
often develop rapidly in severe cases, for example, visual disturbances,
inability to swallow, speech difficulty, muscle coordination, and sensory
abnormalities (numbness of mouth, throat, or extremities). Yellow rain
(mycotoxins) also may have hemorrhagic symptoms which could include
any/all of the following:
Dizziness.
Severe itching or tingling of the skin.
Formation of multiple, small, hard blisters.
7-28

FM 21-11
Coughing up blood.
Shock (which could result in death).
c. First Aid Measures. Upon recognition of an attack employing
toxins or the onset (start) of symptoms listed above, you must
immediately take the following actions:
(1) Step ONE. STOP BREATHING, put on your
protective mask with hood, then resume breathing. Next, put on your
protective clothing.
(2) Step TWO. Should severe itching of the face become
unbearable, quickly—
Loosen the cap on your canteen.
Remove your helmet. Take and hold a deep breath
and remove your mask.
While holding your breath, close your eyes and
flush your face with generous amounts of water.
CAUTION
DO NOT rub or scratch your eyes. Try not to
let the water run onto your clothing or
protective overgarments.
Put your protective mask back on, seat it properly,
clear it, and check it for seal; then resume breathing.
Put your helmet back on.
NOTE
The effectiveness of the M258A1 Skin Decon
Kit for biological agent decon is unknown at
this time; however, flushing the skin with large
amounts of water will reduce the effectiveness
of the toxins.
(3) Step THREE. If vomiting occurs, the mask should be
lifted momentarily and drained–while the eyes are closed and the breath
is held—and replaced, cleared, and sealed.

CHAPTER 8
FIRST AID FOR PSYCHOLOGICAL REACTIONS
INTRODUCTION
During actual combat, military operations continue around the clock, at
a constant pace, and often under severe weather conditions. Terrible
things happen in combat. During such periods the soldier’s mental and
physical endurance will be pushed to the limit. Psychological first aid will
help sustain the soldier’s mental/physical performance during normal
activities, and especially during military operations under extremely
adverse conditions and in hostile environments.
8-1. Explanation of Term “Psychological First Aid”
Psychological first aid is as natural and reasonable as physical first aid
and is just as familiar. When you were hurt as a child, the understanding
attitude of your parents did as much as the psychological effect of a
bandage or a disinfectant to ease the pain. Later, your disappointment or
grief was eased by supportive words from a friend. Certainly, taking a
walk and talking things out with a friend are familiar ways of dealing
with an emotional crisis. The same natural feelings that make us want to
help a person who is injured make us want to give a helping hand to a
buddy who is upset. Psychological first aid really means nothing more
complicated than assisting people with emotional distress whether it
results from physical injury, disease, or excessive stress. Emotional
distress is not always as visible as a wound, a broken leg, or a reaction to
pain from physical damage. However, overexcitement, severe fear,
excessive worry, deep depression, misdirected irritability and anger are
signs that stress has reached the point of interfering with effective
coping. The more noticeable the symptoms become, the more urgent the
need for you to be of help and the more important it is for you to know
HOW to help.
8-2. Importance of Psychological First Aid
First aid can be applied to stress reactions of the mind as well as to
physical injuries of the body. You must know how to give psychological
first aid to be able to help yourself, your buddies, and your unit in order
to keep performing the mission. Psychological first aid measures are
simple and easy to understand. Improvisation is in order, just as it is in
splinting a fracture. Your decision of what to do depends upon your
ability to observe the soldier and understand his needs. Time is on your
side, and so are the resources of the soldier you are helping. Making the
best use of resources requires ingenuity on your part. A stress reaction
resulting in poor judgment can cause injury or even death to yourself or
others on the battlefield. It can be even more dangerous if other persons
are affected by the judgment of an emotionally upset individual. If it is
8-1
FM 21-11
detected early enough, the affected soldier stands a good chance of
remaining in his unit as an effective member. If it is not detected early
and if the soldier becomes more and more emotionally upset, he may not
only be a threat to himself and to others, but he can also severely affect
the morale of the unit and jeopardize its mission.
8-3. Situations Requiring Psychological First Aid
Psychological first aid (buddy aid) is most needed at the first
sign that a soldier cannot perform the mission because of emotional
distress. Stress is inevitable in combat, in hostage and terrorist
situations, and in civilian disasters, such as floods, hurricanes, tornadoes,
industrial and aircraft catastrophes. Most emotional reactions to such
situations are temporary, and the person can still carry on with
encouragement. Painful or disruptive symptoms may last for minutes,
hours, or a few days. However, if the stress symptoms are seriously
disabling, they may be psychologically contagious and endanger not only
the emotionally upset individual but also the entire unit. In such
situations, you may be working beside someone who cannot handle the
impact of disaster. Even when there is no immediate danger of physical
injury, psychological harm may occur. For instance, if a person is unable
to function because of stress, it may cause that person to lose confidence
in himself. If self-confidence cannot be restored, the person then may
become psychologically crippled for life.
Sometimes people continue to function well during the
disastrous event, but suffer from emotional scars which impair their job
performance or quality of life at a later time. Painful memories and
dreams may recur for months and years and still be considered a normal
reaction. If the memories are so painful that the person must avoid all
situations which arouse these memories or if he becomes socially
withdrawn, or shows symptoms of anxiety, depression, or substance
abuse, he needs treatment. Experiences of police, firemen, emergency
medical technicians, and others who deal with disasters has proved that
the routine application of psychological first aid greatly reduces the
likelihood of future serious post-traumatic stress disorders. Thus,
applying psychological first aid as self-aid and buddy aid to all the
participants, including those who have functioned well, is beneficial.
8-4. Interrelation of Psychological and Physical First Aid
Psychological first aid should go hand in hand with physical first aid. The
discovery of a physical injury or cause for an inability to function does not
rule out the possibility of a psychological injury (or vice versa). A physical
injury and the circumstances surrounding it may actually cause an
emotional injury that is potentially more serious than the physical injury;
both injuries need treatment. The person suffering from pain, shock, fear of
serious damage to his body, or fear of death does not respond well to joking,
8-2
•
•
FM 21-11
indifference, or fearful-tearful attention. Fear and anxiety may take as high a
toll of the soldier’s strength as does the loss of blood.
8-5. Goals of Psychological First Aid
The goals of psychological first aid are to–
Be supportive; assist the soldier in dealing with his stress
reaction.
Prevent, and if necessary control, behavior harmful to him
and to others.
Return the soldier to duty as soon as possible after dealing
with the stress reaction.
8-6. Respect for Others’ Feelings
a. Accept the soldier you are trying to help without censorship
or ridicule. Accept his right to his own feelings. Even though your
feelings, beliefs, and behavior are different, DO NOT blame or make light
of him for the way he feels or acts. Your purpose is to help him in this
tough situation, not to be his critic. A person DOES NOT WANT to be
upset and worried; he would “snap out of it” if he could. When he seeks
help, he needs and expects consideration of his fears, not abrupt
dismissal or accusations. You may be impressed with the fact that you
made it through in good condition. You have no guarantee that the
situation will not be reversed the next time.
b. Realize that people are the products of a wide variety of
factors. All persons DO NOT react the same way to the same situations.
Each individual has complex needs and motivations, both conscious and
unconscious, that are uniquely his own. Often, the "straw that breaks the
camel’s back” the one thing that finally causes the person to be
overloaded by the stressful situation is not the stressor itself, but some
other problem. Thus, an injury or an emotional catastrophe will have a
personal meaning for each individual. Even though you may not share
the reactions or feelings of another person and even though the reactions
seem foolish or peculiar, you must realize that he feels as he does for a
reason. You can help him most by accepting this fact and by doing what
you can for him during this difficult time. He is doing the best he can
under the circumstances. Your positive assistance and trust may be what
he needs to do better.
8-7. Emotional and Physical Disability
a. Accept emotional disability as being just as real as physical
disability. If a soldier’s ankle is seriously sprained in a fall, no one
8-3
•
•
•
FM 21-11
(including the injured man himself) expects him to run right away. A
soldier’s emotions may be temporarily strained by the overwhelming
stress of more "blood and guts” than he can take or by a large-scale
artillery attack. DO NOT demand that he pull himself together
immediately and carry on without a break. Some individuals can pull
themselves together immediately, but others cannot. The person whose
emotional stability has been disrupted has a disability just as real as the
soldier who has sprained his ankle. There is an unfortunate tendency in
many people to regard as real only what they can see, such as a wound,
bleeding, or an X-ray of a diseased lung. Some people tend to assume that
damage involving a person’s mind and emotions is just imagined, that he
is not really sick or injured, and that he could overcome his trouble by
using his will power.
b. The terms "it’s all in your head, ” “snap out of it, ” and “get
control of yourself” are often used by people who believe they are being
helpful. Actually, these terms are expressions of hostility because they
show lack of understanding. They only emphasize weakness and
inadequacy. Such terms are of no use in psychological first aid. A
psychological patient or a physical patient with strong emotional
reactions to his injury does not want to feel as he does. He would like to
be effective, but he is temporarily overcome with either fear, anxiety,
grief, guilt, or fatigue. He feels lost and unable to control his emotions.
Reminding him of his failure to act as others do only makes him feel
worse. What he needs is calm, positive encouragement, such as
reminding him that others have confidence in his ability to pull together
and are also counting on him. Often this reassurance combined with
explicit instruction and encouragement to do a simple, but useful task
(that he knows how to do), will restore his effectiveness quickly.
8-8. Emotional Reaction to Injury
Every physically injured person has some emotional reaction to the fact
that he is injured.
a. A minor injury such as a cut finger causes an emotional
reaction in most people. It is normal for an injured person to feel upset.
The more severe the injury, the more insecure and fearful he becomes,
especially if the injury is to a body part which is highly valued. For
example, an injury to the eyes or the genitals, even though relatively
minor, is likely to be extremely upsetting. An injury to some other part of
the body may be especially disturbing to an individual for his own
particular reason. For example, an injury of the hand may be a terrifying
blow to a baseball pitcher or a pianist. A facial disfigurement may be
especially threatening to an actor.
b. An injured person always feels less secure, more anxious, and
more afraid not only because of what has happened to him but because of
8-4
FM 21-11
what he imagines may happen as a result of his injury. This fear and
insecurity may cause him to be irritable, stubborn, or unreasonable. He
also may seem uncooperative, unnecessarily difficult, or even
emotionally irrational. As you help him, always keep in mind that such
behavior has little or nothing to do with you personally. He needs your
patience, reassurance, encouragement and support. Even though he
seems disagreeable and ungrateful at first, ensure that he understands
you want to help him.
8-9. Emotional Reserve Strength of Distressed Soldiers
Realize that distressed soldiers have far more strength than appears at
first glance. An injured or sick person may not put his best foot forward.
The strong points of his personality are likely to be hidden beneath his
fear, anguish, and pain. It is easy to see only his failures even though he
worked efficiently beside you only a short time ago. With your aid he will
again become helpful. Whatever made him a good soldier, rifleman, or
buddy is still there; he is needed.
8-10. Battle Fatigue (and Other Combat Stress Reactions [CSR])
Battle Fatigue is a temporary emotional disorder or inability to function,
experienced by a previously normal soldier as a reaction to the
overwhelming or cumulative stress of combat. By definition, battle
fatigue gets better with reassurance, rest, physical replenishment and
activities which restore confidence. Physical fatigue, or sleep loss,
although commonly present, is not necessary. All combat and combat
support troops are likely to feel battle fatigue under conditions of intense
and/or prolonged stress. They may even become battle fatigue casualties,
unable to perform their mission roles for hours or days. Other negative
behaviors may be CSRs, but are not called battle fatigue because they
need other treatment than simple rest, replenishment and restoration of
confidence. These negative CSRs include drug and alcohol abuse,
committing atrocities against enemy prisoners and noncombatants,
looting, desertion, and self-inflicted wounds. These harmful CSRs can
often be prevented by good psychological first aid; however, if these
negative actions occur, these persons may require disciplinary action
instead of reassurance and rest.
8-11. Reactions to Stress
Most people react to misfortune or disasters (military or civilian,
threatened or actual) after the situation has passed. All people feel some
fear. This fear may be greater than they have experienced at any other
time, or they may be more aware of their fear. In such a situation, they
should not be surprised if they feel shaky, become sweaty, nauseated or
confused. These reactions are normal and are not a cause for concern.
