41. SWIMMING UNDERWATER THROUGH FIRE. If
the heat is too intense or flames too high, swim under
water. (See fig. 45.) To do this:
a. Splash flames away from body.
b. Hold head near water level.
c. If wearing life vest, deflate it by releasing valves.
d. Take a deep breath but do not inhale fumes.
e. Sink beneath the surface, feet =first.
f. Swim upwind as far as possible.
g. Splash away the flames as you come to the surface.
Take a deep breath and submerge again. Repeat pro-
cedure until you are beyond the fire.
h. If wearing life vest, reinflate it by mouth. If you
cannot continue to swim under water, as a last resort
come to the surface as described above, and use the
42. EMERGENCY FLOTATION IN WATER. When in
the water without a life preserver improvise expedients.
a. Use debris. Any floating debris and wreckage
should be used, shared with the greatest number of men.
It is better to cling to planks, boxes, and other floating
articles than to climb upon them. Clinging to floating
debris adds its buoyancy to that of your body. Lash
yourself to debris if possible. Trying to climb up on an
object often leads to frustration and rapid exhaustion.
Only objects large enough for full support should be
boarded. Resting the hands or elbows on an object or
throwing the arms around it may provide sufficient sup-
port. A plank can be used as a surfboard by lying on it,
spreading the legs for balance, and using the arms and
legs for propulsion. (See fig. 46.)
b. Use shirt. Fasten all shirt buttons, including those
of collar and cuffs. Take a deep breath and assume the
jelly-fish float. With the fingers, form an opening in the
shirt front between the second and third buttons, bring
the lips to the opening, and expel the air into the shirt.
This action may be repeated. When the prone position
is resumed, an air pocket forms at the backof the shirt.
(See fig. 47.)
