Carbon Monoxide Can Be Deadly
Carbon Monoxide (CO) is the most toxic substance you’ll come into contact with in your daily life – in your home, at work, garage, car, caravan and boat.
You can’t see or smell carbon monoxide, but at high levels it can kill a person in minutes. Carbon monoxide is produced whenever any fuel such as gas, oil, kerosene, wood, or charcoal is burned. If appliances that burn fuel are maintained and used properly, the amount of CO produced is usually not hazardous. However, if appliances are not working properly or are used incorrectly, dangerous levels of CO can result. Hundreds of people die accidentally every year from CO poisoning caused by malfunctioning or improperly used fuel-burning appliances. Even more die from CO produced by idling cars. Fetuses, infants, elderly people, and people with anemia or with a history of heart or respiratory disease can be especially susceptible. Be safe. Practice the DOs and DON’Ts of carbon monoxide.
Learn more about the dangers of CO and please be aware when boating.

At slow speeds, while idling, or stopped. Be aware that CO can remain in or around your boat at dangerous levels even if your engine or the other boat’s engine is no longer running!
