WARNING
CARBON MONOXIDE (EXHAUST GAS) CAN CAUSE
DEATH.
Carbon monoxide does not have 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 is in 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.

DO NOT operate vehicle engine in a closed place unless
the place has a lot of 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 continue, 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
If required to remain inside the vehicle during extreme heat,
occupants should follow the water intake, work/rest cycle, and
other heat stress preventive medicine measures contained in
FM 21-10, Field Hygiene and Sanitation.
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.
