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.
Outboard engine exhaust fumes contain carbon monoxide. These fumes may concentrate at
the motorwell area. Do not board your vessel with the engine(s) running. Also, do not occupy the
motorwell area with the engine(s) running.
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.

(CO) is produced by all combustion engine(s) and generator sets.
Avoid brain damage or death from carbon monoxide.
Keep cockpit and cabin areas well ventilated.
Avoid blockage of exhaust outlets.
Signs of exposure include headache, nausea, dizziness and drowsiness.
W A R N I N G
BE AWARE
of the significance 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 engine(s) contain (CO). Boats with canvas deployed are more likely to collect
exhaust fumes. Avoid brain damage or death from (CO). Keep cockpit and cabin areas well
ventilated. Signs of exposure include headache, nausea, dizziness and drowsiness.
