SAFETY INFORMATION 15
Carbon Monoxide and
Boating
Burning a material containing carbon
produces carbon monoxide (CO), an
odorless and colorless gas. Because
CO weighs the same as air, it can
spread throughout an enclosed space
unnoticed because you cannot see it
or smell it. Any device used to burn
carbon-based materials on a boat can
be a source of CO. Common sources
of CO include internal combustion en-
gines.
CO reacts with the blood to reduce the
ability of the blood to carry oxygen.
The reduced oxygen supply to body
tissues results in death of the tissue.
Prolonged exposure can cause brain
damage or death. In high concentra-
tions, CO can be fatal within minutes.
The effects of CO in lower concentra-
tions are cumulative and can be just as
lethal over long periods of time.
Symptoms of CO poisoning include:
Itchy and watering eyes, flushed ap-
pearance, throbbing temples, inability
to think coherently, ringing in the ears,
tightness across the chest, head-
aches, drowsiness, nausea, dizziness,
fatigue, vomiting, collapse, and con-
vulsions. If any of these symptoms are
evident, begin treatment immediately.
Prompt action can make the difference
between life and death.
– Evacuate the area and move the vic-
tim to fresh air.
– Administer oxygen if available and
get medical help.
– Open all canvas enclosures to ven-
tilate the area.
– Investigate the source of CO and
take immediate corrective action.
– Be especially aware of other CO
sources which may be near boat.
