Inside the home:
- Install CO alarms (labelled by a recognized laboratory, example ULC, CSA) inside your home to provide early warning of accumulating CO
- CO alarms should be installed in a central location outside each separate sleeping area. If bedrooms are spaced apart, each area will need a CO alarm. CO alarms are not substitutes for smoke alarms. Know the difference between the sound of smoke alarms and CO alarms.
- Have fuel-burning heating equipment (fireplaces, furnaces, water heaters, wood and coal stoves, space or portable heaters) and chimneys inspected by a professional every year before cold weather sets in.
- When purchasing new heating and cooking equipment, select products tested and labelled by a recognized testing laboratory.
- When using a fireplace, open the flue for adequate ventilation.
- Never use your oven to heat your home.
- When buying an existing home, have a qualified technician evaluate the integrity of the heating and cooking systems, as well as the sealed spaces between the garage and house.
Outside the home
- If you need to warm a vehicle, remove it from the garage immediately after starting it. Do not run a vehicle, generator, or other fuelled engine or motor indoors, even if garage doors are open. Make sure the exhaust pipe of a running vehicle is not covered with snow.
- Generators should be operated in well-ventilated locations outdoors away from all doors, windows and vent openings.
- During and after a snowstorm, make sure vents for the dryer, furnace, stove, and fireplace are clear of snow build-up.
- Only use barbecue grills which can produce CO outside. Never use them in the home, garage or near building openings.
- When camping, remember to use battery-powered lights in tents trailers, and motor homes.
- If your CO alarm sounds Immediately move to a fresh air location outdoors and call for help. Remain at the fresh air location until emergency personnel say it is ok.
- If the audible trouble signal sounds, check for low batteries or other trouble indicators.
