CARBON MONOXIDE (EXHAUST GASES) CAN KILL!
• Carbon monoxide is a colorless, odorless, deadly poison which, when breathed, deprives the body of
oxygen and causes suffocation. Exposure to air containing carbon monoxide produces symptoms of
headache, dizziness, loss of muscular control, apparent drowsiness, and coma. Permanent brain damage
or death to personnel can result from severe exposure.
• Carbon monoxide occurs in exhaust fumes of internal combustion engines. Carbon monoxide can
become dangerously concentrated under conditions of inadequate ventilation. The following precau-
tions must be observed to ensure safety of personnel when engine of grader is operated.
1. DO NOT operate engine in enclosed areas without adequate ventilation.
2. DO NOT idle engine without adequate ventilation.
3. DO NOT drive machine with inspection plates or cover plates removed (130G, 130GNS, and 130GNSCE).
4. BE ALERT for exhaust poisoning symptoms. They are:
• Headache
• Dizziness
• Sleepiness
• Loss of muscular control
5. If you see another person with exhaust poisoning symptoms:
• Remove person from area.
• Expose to fresh air.
• Keep person warm.
• DO NOT permit physical exercise.
• Administer cardiopulmonary resuscitation (CPR), if necessary.
• Notify a medic.
6. BE AWARE. The field protective mask for nuclear-biological-chemical (NBC) protection will not protect you from car-
bon monoxide poisoning.
The Best Defense Against Carbon Monoxide Poisoning Is Good Ventilation!
