WARNING
CARBON MONOXIDE (EXHAUST GAS) CAN KILL YOU
Carbon monoxide is without color or smell, but it can kill you.
Breathing air
with carbon monoxide produces symptoms of headache, dizziness, loss of muscular
control,
a sleepy feeling, and coma. Brain damage or death can result from
heavy exposure. Carbon monoxide occurs in the exhaust fumes of fuel-burning
heaters and internal combustion engines.
ly concentrated Carbon monoxide can become dangerous- under conditions of no air movement. Precautions must be
followed to ensure crew safety when the personnel heater, main engine, or
auxiliary engine of any vehicle is operated for any purpose.
1. DO NOT operate personnel heater or engine of vehicle in a closed place,
unless the place has a lot of moving air.
2. DO NOT idle engine for long periods without ventilator blower operating.
3. DO NOT drive any vehicle with inspection plates, cover plates, or engine
compartment doors removed, unless necessary for maintenance purposes.
4. BE ALERT at all times during vehicle operation for exhaust odors and
exposure symptoms. If either is present,
IMMEDIATELY VENTILATE personnel
compartments. If symptoms persist, remove affected crew to fresh air; keep
warm; DO NOT PERMIT PHYSICAL EXERCISE; if necessary, give artificial
respiration.
FOR ARTIFICIAL RESPIRATION, REFER TO FM 21-11.
5. BE AWARE:
the field protective mask for chemical-biological-radiological
(CBR) protection will not protect you from carbon monoxide poisoning.
THE BEST DEFENSE AGAINST CARBON MONOXIDE POISONING IS GOOD VENTILATION.

WARNING
Whenever hood is raised, insert the
S-shaped
safety hook through the two
matching holes in the prop channels to
prevent
the hood
from falling
accidentally.
WARNING
Let radiator cool before removing cap.
Remove
radiator cap in two steps.
First, place a thick cloth over the
cap and slowly rotate cap counter-
clockwise to its first stop; pause,
and let pressure escape from cooling
system.
Then rotate cap further coun-
terclockwise until you can remove it.
Failure to follow this procedure can
result in serious burns.
WARNING
Do not smoke, have open flames, or
make sparks around
the batteries,
especially if the caps are off. Bat-
tery gases can explode and cause
injury.
WARNING
Particles blown by compressed air are
hazardous. Always direct air stream
away from the user and other persons
in the area. User must wear a safety
eyeshield when using compressed air in
cleaning.
WARNING
Improper cleaning methods and use of
unauthorized cleaning solvents could
injure personnel and damage equipment.
See TM 9-247 for proper cleaning

WARNING
Ether is highly explosive. Dispose of
ether cylinders properly. Be alert
for the strong odor of spilled ether.
Guard against flame or sparks in work
area when servicing ether cylinder.
WARNING
During normal operation, the exhaust
pipes and muffler can become very hot.
Be careful not to touch these compo-
nents with your bare hands. Do not
allow your body to come in contact
with
the hot pipes or muffler.
Exhaust system components may be hot
enough to cause serious burns.
WARNING
Cooling system components become hot
during operation. To avoid personal
injury, do not service cooling system
components until cooling system has
cooled down.
WARNING
Always remove negative battery ground
cables first and install them last to
avoid sparks that can cause an explo-
sion. Failure to follow this pre-
caution may result in serious injury
to you and other personnel.
