DANGER
A.8 Engine Exhaust:
Gasoline-powered engines and tools present a serious health hazard. They produce high
concentrations of carbon monoxide (CO). CO is a poisonous gas that can cause illness,
permanent neurological damage and death. CO is colorless, odorless, and non-irritating
and therefore can overcome exposed persons without warning. CO can rapidly accumulate
(even in areas appearing to be well ventilated).

Engines"
