Common Household Sources:
* Fuel-burning appliances: Furnaces, water heaters, stoves, fireplaces, and gas dryers.
* Vehicles: Cars, trucks, and other vehicles with internal combustion engines, especially when idling or running in enclosed spaces.
* Generators: Portable generators used during power outages.
* Cigarettes: Burning cigarettes produce CO.
Other Sources:
* Industrial processes: Manufacturing, power plants, and other industrial processes that involve burning fuels.
* Wildfires: Large wildfires can release significant amounts of CO into the atmosphere.
* Incomplete combustion: Any time a fuel source is burned without enough oxygen, CO can be produced.
Important Note: Carbon monoxide poisoning can be fatal. Always ensure proper ventilation when using fuel-burning appliances, never run vehicles or generators in enclosed spaces, and be aware of the potential for CO buildup during wildfires.
