TEST
WARNING
Touching exhaust system during test can cause severe burns.
Exposure to exhaust gases produces symptoms of headache, dizziness, loss
of muscular control, drowsiness, or coma. Brain damage or death can re-
sult from severe exposure.
Fumes from engines become concentrated with poor ventilation.
1. Operate engine in a ventilated area only.
2. Ventilate personnel compartments when idling engine.
3. While running vehicle, be alert for fumes. Keep compartments venti-
lated. If someone is overcome, expose to fresh air; keep warm and
still; give artificial respiration if needed. Seek medical attention.
Administer oxygen, if available.
GOOD VENTILATION IS THE BEST DEFENSE AGAINST EXHAUST
POISONING.
