Where Does Carbon Monoxide Come From?
Carbon monoxide (CO) can be produced by any fuel-burning appliance that is malfunctioning or improperly installed. Here are some common sources:
- Household Appliances: Furnaces, gas ranges/stoves, gas clothes dryers, water heaters, portable fuel-burning space heaters, fireplaces, generators, and wood-burning stoves.
- Vehicles and Engines: Vehicles, generators, and other combustion engines.
- Blocked Chimney or Flue: A blocked chimney or flue can prevent CO from escaping, leading to a buildup inside the home.
- Furnace Issues: A cracked or loose furnace exchanger can release CO.
- Air Pressure Changes: Back drafting and changes in air pressure can cause CO to enter living spaces.
- Improper Use of Grills: Operating a grill in an enclosed space can produce dangerous levels of CO.
