GENERAL INFORMATION
Early symptoms of carbon monoxide poisoning which should not
be confused with seasickness or intoxication, include headache,
dizziness, drowsiness, and nausea.
Carbon monoxide poisoning can lead to unconsciousness, brain
damage, or death. Keep the boat well ventilated while at rest or
underway and avoid prolonged exposure to carbon monoxide.
POOR VENTILATION
Under certain running and/or wind conditions, permanently
enclosed or canvas enclosed cabins or cockpits with insufficient
ventilation may draw in carbon monoxide. Install one or more
carbon monoxide detectors in your boat.
Although the occurrence is rare, on a very calm day, swimmers
and passengers in an enclosed area of a stationary boat that
contains or is near a running engine may be exposed to a
hazardous level of carbon monoxide.
While Boat Is Stationary
a
a - Running the engine when the boat is moored in a confined
space.
b - Mooring close to another boat that has its engine running.
