Carbon monoxide (CO) is a colorless, odorless, and deadly gas. It’s produced by burning fuels such as natural gas, propane, wood, oil, or charcoal—and it can leak from appliances like furnaces, fireplaces, water heaters, and stoves.
In older homes, and homes with attached garages, are especially at risk. Common CO sources include:
- Faulty furnaces or boilers
- Gas ranges or ovens
- Vehicle exhaust from attached garages
- Blocked chimneys or flues
Symptoms of carbon monoxide poisoning can include:
- Headaches
- Dizziness
- Nausea
- Shortness of breath
- Confusion or loss of consciousness
Each year, over 20,000 Americans are treated for CO poisoning. Properly installed and maintained CO detectors are your best defense.
