Carbon Monoxide Safety What is Carbon Monoxide? Carbon monoxide (CO) is an odorless, colorless, poisonous gas created when any fuel is burned – gasoline, propane, natural gas, oil, wood, coal, and even tobac- co. When combustion air is limited, more CO is produced. Serious problems can develop when combustion by-products are not properly vented outside the house.
Page 22
Carbon Monoxide Safety When these appliances are in good working condition with proper ventilation, lethal carbon monoxide gas is vented outdoors where it quick- ly disperses. But even the slightest malfunction or misuse of any of these sources can lead to a build-up of carbon monoxide in your home that can become dead- ly before you’d even know it’s there.
