SECTION XII. OPERATION UNDER UNUSUAL CONDITIONS
2-134. OPERATION IN COLD ENVIRONMENT, -25F TO 32F (-32C TO 0C).
Do not touch extremely cold metal (below -26F [-32C]). Bare
skin may freeze to cold metal and cause injury to personnel.
All valves should be opened and closed slowly during any
procedure. Sudden changes in pressure may cause equipment
to react faster than personnel can be alerted. Make sure
surrounding personnel are aware of changes being made to
settings on equipment. Failure to comply may result in injury
or death to personnel and damage to equipment.
Diesel fuel compartment heaters come on automatically when
truck engine is running and air temperature is below (+39F
[4C]). CARBON MONOXIDE (EXHAUST GAS) CAN KILL
YOU. Carbon monoxide is a colorless, odorless, DEADLY
POISONOUS gas and when breathed deprives body of oxygen
and causes SUFFOCATION. Breathing air with carbon
monoxide produces symptoms of headache, dizziness, loss of
muscular control, a sleepy feeling, and coma. Permanent
BRAIN DAMAGE or DEATH can result from severe exposure.
Precautions MUST be followed to make sure personnel are safe
whenever compartment heaters or engine are operated for any
purpose. Injury to personnel may result.
DO NOT operate compartment heaters or engine of truck in
enclosed area without adequate ventilation. BE ALERT at all
times whenever BATTERY switch is ON, truck engine is
running, and air temperature is below (+39F [4C]) for exhaust
symptoms. If either are present, IMMEDIATELY EVACUATE
AND VENTILATE the area. Affected personnel treatment shall
be: expose to fresh air; keep warm; DO NOT PERMIT
PHYSICAL EXERCISE; if necessary, give artificial respiration
as described in FM 21-11 and get medical attention. BE
AWARE; neither the gas particulate filter unit nor field
protection mask for nuclear-biological-chemical protection will
protect you from carbon monoxide poisoning. THE BEST
DEFENSE AGAINST CARBON MONOXIDE POISONING IS
