WARNING
CARBON MONOXIDE (EXHAUST GAS) CAN CAUSE DEATH.
Carbon monoxide is without color or smell, but can cause death, 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. Carbon monoxide can
become dangerously concentrated under conditions of no ventilation.
Precautions must be followed to ensure crew safety when the personnel heater
or engine of any vehicle is operated for any purpose.
1.
2.
3.
4.
DO NOT operate personnel heater or engine of vehicle in a closed place
without proper ventilation.
DO NOT drive any vehicle with inspection plates, cover plates, or engine
compartment covers 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 affected crew to fresh
air and keep warm. DO NOT PERMIT PHYSICAL EXERCISE. If necessary, give
artificial respiration and get immediate medical attention. For artificial
respiration, refer to FM 21-11.
BE AWARE that the gas particulate filter unit or the field protection mask for
nuclear-biological-chemical protection WILL NOT offer safety from carbon
monoxide poisoning.
THE BEST DEFENSE AGAINST CARBON MONOXIDE POISONING IS GOOD
VENTILATION.
WARNING
Adhesives, solvents, and sealing compounds can burn easily, can give off harmful
vapors, and are harmful to skin and clothing. To avoid injury or death, keep away
from open fire and use in well-ventilated area. If adhesive, solvent, or sealing
compound gets on skin or clothing, wash immediately with soap and water.
WARNING
Never use the parking brake for normal braking or wheels will lock up causing
severe skid. Skidding vehicle could result in serious injury or death.
WARNING
.
Fuel is very flammable and can explode easily. TO avoid serious irjury or death,
keep fuel away from open fire and keep fire extinguisher within easy reach when
working with fuel. Do not work on fuel system when engine is hot. Fuel can be
ignited by hot engine. When working with fuel, post signs that read NO
SMOKING WITHIN 50 FEET of vehicle.
Remove rings, bracelets, wristwatches, neck chains, and any other jewelry before
working around vehicle. Jewelry can catch on equipment and cause Injury, or
may short across an electrical circuit and cause severe burns or electrical shock.
TM9-2815-224-34&P
WARNING
The radiator is very hot and pressurized during vehicle operation. Let radiator
cool before removing cap. Failure to do so can result in serious burns.
WARNING
The exhaust pipe and muffler can become very hot during vehicle operation. Be
careful not to touch these parts with bare hands, or allow body to come in
contact with pipe or muffler. Exhaust system parts can become hot enough to
cause serious burns.
WARNING
Always use seatbelts when operating vehicle. Failure to use seatbelt can result in
serious injury in case of accident.
WARNING
When working inside the vehicle with power off, be sure to ground every
capacitor likely to hold a dangerous voltage potential.
Be careful when working on or with electrical equipment. Do not be misled by
the term "low voltage”. Voltages as low as 50 volts may cause death. For
artificial respiration, refer to FM 21-11.
WARNING
Be careful not to short out battery terminals. Do not smoke or use open flame
near batteries. Batteries may explode from a spark. Battery acid is harmful to
skin and eyes.
Starting fluid is toxic and flammable. Do not store in cab and do not breathe
fumes. Do not puncture or burn containers. Dispose of container following
manufacturer’s recommendations on the container.
WARNING
Compressed air used for cleaning purposes will not exceed 30 psi (207 kPa). Use
only with effective chip guarding and personal protective equipment, goggles,
shield, and gloves.
WARNING
After Nuclear, Biological, or Chemical (NBC) exposure of vehicle, all air filters
shall be handled with extreme caution. Unprotected personnel can experience
injury or death if residual toxic agents or radioactive material are present. If
vehicle is exposed to chemical or biological agents, servicing personnel shall wear
protective mask, hood, protective overgarments, and chemical protective gloves
and boots in accordance with TM 10-277. All contaminated air filters shall be
placed in double-lined plastic bags and moved swiftly to a segregation area away
from the worksite. The same procedure applies for radioactive dust
contamination. The Company NBC team should measure the radiation prior to
filter removal to determine the extent of safety procedures required per the NBC
Annex to the unit Standard Operating Procedures (SOP). The segregation area in
which the contaminated air filters are temporarily stored shall be marked with
appropriate NBC placards. Final disposal of contaminated air filters shall be in
accordance with local SOP. Decontamination operation shall be in accordance
with TM 3-220 and local SOP.
