Be Alert To Carbon Monoxide Poisoning

Carbon monoxide is present in the exhaust fumes of all internal
combustion engines including the outboards, stern drives 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 ventila-
tion. Prolonged exposure to carbon monoxide 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.
