WARNING

CARBON MONOXIDE POISONING CAN BE DEADLY

Carbon monoxide is a colorless, odorless, deadly poisonous gas, which when breathed deprives the body

of oxygen and causes suffocation. Exposure to air contaminated with carbon monoxide produces

symptoms of headache, dizziness, loss of muscular control, apparent drowsiness, and/or 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 inadequate ventilation. The following precautions must be observed to

make sure of the safety of personnel whenever the personnel heater, main or auxiliary 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 the area is

ADEQUATELY VENTILATED.

DO NOT idle engine for long periods without maintaining ADEQUATE VENTILATION in

personnel compartments.

DO NOT drive any vehicle with inspection plates, cover plates, or engine compartment doors

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 personnel from vehicle and treat as follows: expose to fresh air; keep warm; DO

NOT PERMIT PHYSICAL EXERCISE.

THE BEST DEFENSE AGAINST CARBON MONOXIDE POISONING IS ADEQUATE

VENTILATION.

For artificial respiration, refer to FM 21-11,
