TREAT HEAT EXHAUSTION
Heat exhaustion is treated by having the casualty drink water and by taking
precautions to keep his condition from becoming worse.
a. Protect Casualty From Sun. Move the casualty to a cool, shaded area to
rest. If shade is not available, improvise a shade using ponchos, blankets, or other
available materials to protect the casualty from direct sunlight. Have the casualty lie
down in a comfortable position.
b. Loosen Clothing. Loosen or remove any tight-fitting clothing or boots,
unless you are in a chemical environment. If you are in a chemical environment, do not
loosen or remove the casualty's protective mask, protective clothing, or boots.
c. Cool Casualty. If it is a very hot day, pour water over the casualty and fan
him to promote the loss of body heat.
If you are in a chemical environment, do not pour water over the casualty.
d. Elevate Legs. Elevate the casualty's legs so his feet are above the level of
his heart and place a pack, small log, rolled-up field jacket, or other stable prop under
his feet. If a litter is available, have the casualty lie on the litter and elevate the foot of
the litter. Elevating his legs will help blood to return from his legs to his heart and will
help to prevent shock.
