Boating Emergencies
What makes carbon monoxide (CO) from a boat's engine so dangerous?
Answer
It is colorless and odorless, and can build up to deadly levels before anyone notices
Carbon monoxide is a colorless, odorless gas in engine and generator exhaust. It can accumulate in and around a boat and cause poisoning or death before anyone realizes it, so keep exhaust areas clear and ventilate cabins.
