How to prevent it
- Ensure fuel-burning appliances, chimneys and vents are cleaned and inspected by professionals every year before cold weather sets in. Visit COSafety.ca to find a registered contractor near you.
- Ensure vents for the dryer, furnace, stove, fireplace and other fuel-burning appliances should always be clear of snow and other debris.
- Gas and charcoal barbeques should only be used outside, away from all doors, windows, vents, and other building openings. Never use barbeques inside garages, even if the garage doors are open.
- Portable fuel-burning generators should only be used outdoors in well-ventilated areas away from windows, doors, vents and other building openings.
- Ensure all portable fuel-burning heaters are vented properly, according to manufacturer’s instructions.
- Never use the stove or oven to heat your home.
- Open the flu before using a fireplace for adequate ventilation.
- Never run a vehicle or other fueled engine or motor inside a garage, even if the garage doors are open. Always remove a vehicle from the garage immediately after starting it.
