Be Alert To Carbon Monoxide Poisoning
Carbon monoxide is present in the exhaust fumes of all internal combustion engines including the outboards,
sterndrives and inboard engines that propel boats, as well as the generators that power various boat
accessories. Carbon monoxide is a deadly gas that is odorless, colorless and tasteless.
Early symptoms of carbon monoxide poisoning, which should not be confused with seasickness or intoxication,
include headache, dizziness, drowsiness, and nausea.
Avoid the combination of a running engine and poor ventilation. Prolonged exposure to carbon mon-
oxide in sufficient concentration can lead to unconsciousness, brain damage or death.
GOOD VENTILATION
Ventilate passenger area, open side curtains, or forward hatches to remove fumes.
