WARNING
EXHAUST GASES CAN BE DEADLY
Exposure to exhaust gases produces symptoms of headache, dizziness, loss of muscular control,
apparent drowsiness, and coma. Permanent brain damage or death can result from severe expo-
sure.
Carbon monoxide occurs in the exhaust fumes of fuel burning heaters and internal combustion
engines, and becomes dangerously concentrated under conditions of inadequate ventilation. The
following precautions must be observed to insure the safety of personnel whenever fuel burning
heater(s) or engine of any vehicle is operated for maintenance purposes or tactical use.
Do not operate heater or engine of vehicle in an enclosed area unless it is adequately ventilated.
Do not idle engine for long periods without maintaining adequate ventilation in personnel com-
partments.
Do not drive any vehicle with inspection plates or cover plates removed unless necessary for
maintenance purposes.
Be alert at all times during vehicle operation for exhaust odors and exposure symptoms. If either
are present, immediately ventilate personnel compartments. If symptoms persist, remove af-
fected personnel from vehicle and treat as follows: expose to fresh air; keep warm; do not per-
mit physical exercise; if necessary, administer artificial respiration.
If exposed, seek prompt medical attention for possible delayed onset of acute lung congestion.
Administer oxygen if available.
The best defense against exhaust gas poisoning is adequate ventilation.
WARNING
Serious or fatal injury to personnel may result if the
following instructions are not complied with.
Use extreme care when removing radiator cap, especially when temperature gage shows above
1800 F (82.20°C).
Always wear leather gloves when handling winch cable. Never allow cable to slip through
hands. Do not operate winch with less than four turns of cable on drum.
Do not drive truck until the low air pressure warning buzzer is silent and the air pressure gage
shows at least 85 PSI (586.075 kPa). This is the minimum pressure required for safe braking
action.
