Carbon Monoxide
Carbon Monoxide (CO) is a colorless and odorless gas produced by all engines and fuel
burning appliances. Even with the best boat design and construction, plus the utmost care
in inspection, operation, and maintenance, hazardous levels of CO may still be present in
accommodation spaces under certain conditions. To reduce CO accumulation, always
ventilate the boat interior and avoid boating situations which cause increased exposure.

burning appliances produce CO as exhaust. Direct and
prolonged exposure to CO will cause BRAIN DAMAGE or
