Carbon Monoxide Safety


Carbon monoxide (CO) is a colourless, odourless toxic gas. When inhaled, CO interferes with the blood's ability to absorb and transport oxygen. 

Carbon monoxide is produced when fuels are burned incompletely. Tobacco smoking, idling gasoline-powered vehicles, and the burning of oil, coal, wood, charcoal, kerosene, propane or natural gas can all produce carbon monoxide. 

The risk of carbon monoxide poisoning from regularly maintained appliances that are properly ventilated is extremely low. However, improperly installed, operated or poorly maintained appliances that use these fuels may create unsafe levels of CO. In enclosed spaces like your home, vehicle, cottage, boat, recreational vehicle or tent, even a small amount of CO is dangerous.
