WARNING
EXHAUST GASES CAN BE DEADLY
Exposure to exhaust gases produces symptoms of headache, dizziness, loss of muscu-
lar control, apparent drowsiness, and coma. Permanent brain damage or death can
result from severe exposure.
Carbon monoxide occurs in the exhaust fumes of fuel burning heaters and internal
combustion engines, and becomes dangerously concentrated under conditions of inade–
quate 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 person-
nel compartments.
Be alert at all times during vehicle operation for exhaust odors and exposure symptoms.
If either are present, immediately ventilate personnel compartments. If symptoms per-
sist, remove affected personnel from vehicle and treat as follows: expose to fresh air;
keep warm; do not permit physical exercise; if necessary, administer artificial
respiration.
If exposed, seek prompt medical attention for possible delayed onset of acute lung con-
gestion.
Administer oxygen if available.
The best defense against exhaust gas poisoning is adequate ventilation.
Serious or fatal
complied with.
