Exhaust Emissions
Be Alert To Carbon Monoxide Poisoning
Carbon monoxide is produced in the exhaust fumes of all gasoline propulsion engines and generator sets.
Carbon monoxide is a deadly odorless, colorless and tasteless gas.
Early stages of carbon monoxide sickness, which can lead to unconsciousness, brain damage, or death, include
headache, dizziness, drowsiness, and nausea. Do not mistake for seasickness.
Poor Ventilation
Under certain running and/or wind conditions, permanently enclosed or canvas enclosed cabins or cockpits may
draw in carbon monoxide. Install one or more carbon monoxide detectors in your boat.
Examples of Poor Ventilation:
1 Running engine in a confined space.
2 Boats moored close together.
3 Trim angle of bow too high.
4 Back-drafting (station wagon effect).
Good Ventilation
Ventilate passenger area, open side curtains, or forward hatches to remove fumes.
Example of Good Ventilation:
5 Desired air flow through the boat.
