ONOXIDE
Carbon Monoxide, commonly written CO, is a colorless, odorless gas emitted from any boat’s
exhaust. The gas is similar in weight to the air we breathe. Therefore, it cannot be expected to rise
or fall, but will accumulate in confined spaces.
Carbon monoxide is
poisonous
and potentially
fatal
if breathed over an extended period of
time. Symptoms of CO poisoning include: dizziness, nausea, headache, sleepiness, vomiting,
throbbing in the temples, muscular twitching, and an inability to think clearly.
If you or anyone
else experience these symptoms, immediately get away from fumes and into an area where
plenty of FRESH air can be consumed. If any symptoms from above persist, seek medical
attention.
Carbon monoxide can accumulate in cabins and under canvas.
If your boat is equipped
with a canvas that encloses the aft cockpit and propulsion equipment, do not operate the boat with
this canvas closed.
Operators need to be aware of the influence of other boats on their vessel as well as the effects
they have on neighboring crafts. Of primary concern is the operation of an auxiliary generator
with boats moored along side each other. This situation creates an atmosphere which is filled with
CO, and extremely dangerous.
D A N G E R
CO is produced by all gasoline engines and generator sets. Keep cockpit and cabin areas well
ventilated and avoid blockage of exhaust outlets. Extended exposure to (CO) can cause brain
damage or death. Signs of exposure include headache, nausea, dizziness, and drowsiness.
W A R N I N G
BE AWARE
of the affect your exhaust may have on other vessels. Likewise,
BE AWARE
that the
operation of other vessel's equipment may influence the carbon monoxide concentration on
your
vessel.
W A R N I N G
Exhaust fumes from engines contain CO. Boats with canvas deployed are more likely to collect
exhaust fumes. Keep cockpit and cabin areas well ventilated.
