EXHAUST EMISSIONS
BE ALERT TO CARBON MONOXIDE POISONING
Carbon monoxide (CO) is a deadly gas that is present in the
exhaust fumes of all internal combustion engines, including the
engines that propel boats, and the generators that power boat
accessories. By itself, CO is odorless, colorless, and tasteless, but if
you can smell or taste engine exhaust, you are inhaling CO.
Early symptoms of carbon monoxide poisoning, which are similar to
the symptoms of seasickness and intoxication, include headache,
dizziness, drowsiness, and nausea.
!
WARNING
Inhaling engine exhaust gases can result in carbon monoxide
poisoning, which can lead to unconsciousness, brain damage, or
death. Avoid exposure to carbon monoxide.
Stay clear from exhaust areas when engine is running. Keep the
boat well‑ventilated while at rest or underway.
STAY CLEAR OF EXHAUST AREAS
Engine exhaust gases contain harmful carbon monoxide. Avoid
areas of concentrated engine exhaust gases. When engines are
running, keep swimmers away from the boat, and do not sit, lie, or
stand on swim platforms or boarding ladders. While underway, do
not allow passengers to be positioned immediately behind the boat
(platform dragging, teak/body surfing). This dangerous practice not
only places a person in an area of high engine exhaust
concentration, but also subjects them to the possibility of injury from
the boat propeller.
GOOD VENTILATION
Ventilate the passenger area, open side curtains or forward hatches
to remove fumes.
Example of desired air flow through the boat:
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.
