WARNING
CARBON MONOXIDE (EXHAUST GAS) CAN KILL YOU
Carbon monoxide is without color or smell, but can kill you. Breathing air with carbon monoxide
produces symptoms of headache, dizziness, loss of muscular control, a sleepy feeling, and coma.
Heavy exposure can cause brain damage or death. Carbon monoxide gas occurs in the exhaust fumes
of internal combustion engines, and can become dangerously concentrated under conditions of no air
movement. To ensure your safety and that of other maintenance personnel, always observe the
following precautions:
DO NOT operate engine in a closed place unless the place has a lot of moving air. Engine should be
kept at least five feet away from buildings and other equipment during operation.
DO NOT idle engine for long periods without proper ventilation.
BE ALERT at all times for exhaust odors and exposure symptoms. If either is present, IMMEDIATELY
VENTILATE personnel compartments; remove affected crew to fresh air; keep warm; if necessary,
give artificial respiration. FOR ARTIFICIAL RESPIRATION REFER TO FM 21-11.
BE AWARE; the field protective mask for chemical-biological-radiological (CBR)
THE BEST DEFENSE AGAINST CARBON MONOXIDE POISONING IS GOOD VENTILATION.
