PRELIMINARY STARTING PROCEDURES
EXHAUST GAS CAN KILL YOU
Exhaust gas is without color or smell, but can kill you. Breathing exhaust gas produces
symptoms of headache, dizziness, loss of muscular control, a sleepy feeling, and
coma. Brain damage or death can result from heavy exposure to exhaust fumes of fuel-
burning internal combustion engines. Exhaust gases can become dangerously
concentrated under conditions of no air movement. Precautions must be followed to
ensure crew safety when the engine of any vehicle is operated for any purpose.
DO NOT operate vehicle engine inside building unless ample ventilation is available.
DO NOT idle engine for long periods without ventilator blower operating.
DO NOT drive any vehicle with inspection plates, cover plates, or engine com-
partment doors removed unless necessary for maintenance purposes.
BE ALERT at all times during vehicle operation for exhaust odors and exposure
symptoms. If either is present, IMMEDIATELY VENTILATE personnel compart-
ments. If symptoms persist, remove affected crew to fresh air; keep warm; DO
NOT PERMIT PHYSICAL EXERCISE; if necessary, give artificial respiration.
FOR ARTIFICIAL RESPIRATION, REFER TO FM21-11.
BE AWARE; the field protective mask for chemical-biological-radiological (CBR)
protection will not protect you from carbon monoxide poisoning.
THE BEST DEFENSE AGAINST CARBON MONOXIDE POISONING IS GOOD VENTILATION.
