Carbon monoxide is produced whenever a material burns, and it can be emitted in a house from a variety of sources. Some of the most common sources of carbon monoxide in a house include:

• Fuel-burning appliances: Homes with fuel-burning appliances or attached garages are more likely to have carbon monoxide problems. Common sources of carbon monoxide in homes include fuel-burning appliances and devices such as clothes dryers, water heaters, furnaces or boilers, and gas ranges.

• Poorly maintained or ventilated appliances: The most common causes of carbon monoxide building up are incorrectly installed or poorly maintained or ventilated appliances such as stoves, hot water heaters, and fireplaces.

• Vehicle exhaust: Carbon monoxide can also be emitted from vehicle exhaust, so it is important to never leave a car or truck running in a garage, even with the garage door open.

• Generators: Generators can also emit carbon monoxide, so they should always be used outside and downwind from doors and windows that are open.

• Grills: Burning charcoal or using a portable gas camp stove or grill indoors can cause carbon monoxide to build up inside your home, cabin, or camper.

It is important to install a carbon monoxide alarm outside every sleeping area and on every level of your home to detect any carbon monoxide leaks and prevent any hazards.
