Carbon Monoxide Poisoning

Boat showing areas vulnerable to carbon monoxideA deadly gas produced when carbon-based fuels are burned causes carbon monoxide poisoning.

Carbon monoxide is an odorless and tasteless gas. It enters the bloodstream through the lungs and displaces the oxygen. Exposure can cause nausea, headache, dizziness, mental confusion and even unconsciousness. The symptoms can be mistaken for seasickness or the flu. If someone displays these symptoms, place them in fresh air immediately.

Sources on your boat could include the engine, generators, cooking equipment, and heating appliances.

People are most commonly exposed by: :

A new and dangerous boating fad involves an individual holding on to the swim platform of a boat while a wake builds up, then letting go to surf the wave created by the boat. Termed "Teak Surfing", this practice is a sure way to induce CO poisoning. NEVER swim near the stern of your boat with the engine(s) running.

To protect yourself, maintain and inspect the boat's engine and exhaust system. Keep forward hatches open to provide air flow. Install a carbon monoxide detector. Be aware of other boats near you that may be running a generator or idling for long periods while docked. Their carbon monoxide can get into your boat too.
