Carbon monoxide is produced whenever a material burns. 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
- Gas ranges or ovens
- Fireplaces
- Charcoal grills
- Generators
- Power tools and lawn equipment
Carbon monoxide can build up in a home due to incorrectly installed or poorly maintained or ventilated appliances. A furnace malfunction, blocked dryer vent, or fireplace or charcoal grill that is not properly vented can also cause carbon monoxide levels to rise. To prevent carbon monoxide poisoning, it is recommended to have furnaces and heaters inspected every year, install a carbon monoxide detector in your house, and make sure your gas appliances are vented properly.
