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 in-
adequate 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 per-
sonnel compartments.
Do not drive any vehicle with inspection plates or cover plates removed unless neces-
sary for maintenance purposes.
Be alert at all times during vehicle operation for exhaust odors and exposure symp-
toms. If either are present, immediately ventilate personnel compartments. If
symptoms persist, remove affected personnel from vehicle and treat as follows:
expose to fresh air; keep warm; do not permit physical exercise; if necessary, ad-
minister 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.
Always wear protective gloves when handling winch cable. Do not let winch cable
slip through hands. Rusty or broken wires can cause serious injury.
Always use hand THROTTLE to control engine speed when operating winch. Avoid
sudden changes in speed or high speed. Rough, jerky operation may cause broken
shear pins and snapped cables, damage to vehicle or injury to personnel.
Dry cleaning solvent is flammable. Do not use near an open flame. Keep a fire ex-
tinguisher nearby when solvent is used. Use only in well-ventilated places. Failure
to do this may result in injury to personnel and damage to equipment.
Eye shields must be worn when using grinder. Eye injury can occur if eye shields
are not used.
Never work under dump body unless safety braces are in place. Dump body could
drop and personnel could be seriously injured.
Do not work on hot heater exhaust tube. Let it cool before removing it. Hot ex-
haust tube can cause serious burns.
Eye shields must be worn when using compressed air. Eye injury can occur if eye
shields are not used.
