High efficiency furnaces, water heaters and other energy-saving appliances may have exhaust vents that exit your home through an exterior wall rather than through a chimney. These vents can become blocked in the winter months by snow and ice, which can affect the safe operation of the appliance. Make sure that all snow, ice and other obstructions are removed from your venting systems. Drifting snow can cause a buildup of carbon monoxide inside of your home.
Often referred to as the “silent killer,” CO is an invisible, tasteless and odorless gas that can cause serious illness or death. The poisonous gas is produced when fuels, such as propane, gasoline, natural gas, heating oil or wood do not burn completely in fuel-burning appliances, such as furnaces, fireplaces, hot water heaters, stoves, barbecues, portable heaters and generators, or vehicles.
Exposure to CO can cause flu-like symptoms, such as headaches, nausea and dizziness, burning eyes, confusion, drowsiness and loss of consciousness. If you or others in your household or building have these symptoms, go outdoors and call 911 immediately. If your CO alarm sounds and no one is suffering from symptoms of CO poisoning, check to see if the battery needs replacing or if the alarm has reached its “end-of-life” before calling 911.
Here are additional CO safety tips and recommendations from the National Fire Protection Association:
- If you have been exposed to CO, move to a fresh air location outdoors or by an open window or door. Make sure everyone inside the home or building is accounted for. Call for help from a fresh air location and stay there until emergency personnel arrive.
- If you need to warm a vehicle, remove it from the garage immediately after starting it. Do not run a vehicle or other fueled engine or motor indoors, even if garage doors are open. Make sure the exhaust pipe of a running vehicle is not covered with snow.
- A generator should be used in a well-ventilated location outdoors away from windows, doors and vent openings.
- Only use gas or charcoal grills outside.
