What is it?
Carbon monoxide is a colorless, highly poisonous gas. Under pressure, it becomes a liquid. It is produced by burning gasoline, natural gas, charcoal, wood, and other fuels.
Appliances, tools, space heaters, and generators that use these fuels can produce carbon monoxide through incomplete combustion. Vehicle exhaust and tobacco smoke contain carbon monoxide. It can be released from wildfires.
Carbon monoxide is most dangerous in enclosed spaces such as garages or indoor rooms.
