Carbon Monoxide (Continued)
Early symptoms of CO poisoning are often confused with seasickness or intoxication, thus those
individuals affected may not receive adequate medical attention. As the owner/operator, you must
be aware of Carbon Monoxide concentrations and its effects on passengers and crew.
Dangerous concentrations of Carbon Monoxide may be present if:
1 There is leakage in the engine exhaust system.
2 There is leakage in a generator exhaust system.
3 There is insufficient fresh air circulation.
4 Fumes move from the aft section of the vessel into the cabin and cockpit area.
5 Exhaust gas becomes trapped in enclosed places.
6 Exhaust outlets become blocked.
7 A back draft or "station wagon effect" occurs.
8 Your vessel is situated next to, and receives exhaust from, the neighboring vessel.
9 Your vessel is slow, idling, or stopped.
Carbon Monoxide is colorless, odorless, and tasteless.
To protect yourself and passengers from CO poisoning:
1 Maintain sufficient ventilation at all times.
2 Operate all fuel-burning appliances in a location where fresh air can circulate.
3 Keep all passengers away from exhaust outlets.
4 If fumes are detected, CO is present. Take steps to ventilate the area.
5 Symptoms of seasickness could be CO poisoning. Get the affected person to fresh air
Seek medical attention, unless you are positive it is NOT Carbon Monoxide poisoning.
6 Review the Coast Guard pamphlet included with this documentation.
7 Get a vessel safety check.
