Avoid carbon monoxide poisoning
All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide can
cause headaches, dizziness, drowsiness, nausea, confusion, and eventually death.
Carbon monoxide is a colorless, odorless, tasteless gas which may be present even if you do not
see or smell any engine exhaust. Deadly levels of carbon monoxide can collect rapidly and you
can quickly be overcome and unable to save yourself. Also, deadly levels of carbon monoxide
can linger for hours or days in enclosed or poorly-ventilated areas. If you experience any symp-
toms of carbon monoxide poisoning, leave the area immediately, get fresh air, and SEEK MEDI-
CAL TREATMENT.
• Do not run engine indoors. Even if you try to ventilate engine exhaust with fans or open win-
dows and doors, carbon monoxide can rapidly reach dangerous levels.
• Do not run engine in poorly ventilated or partially enclosed areas such as barns, garages, or
carports.
• Do not run engine outdoors where engine exhaust can be drawn into a building through open-
ings such as windows and doors.
