Install carbon monoxide (CO) alarms in your home in these two locations:
- outside of all sleeping areas or near all bedrooms.
- on every storey or floor, including storeys that do not have sleeping areas.
Ensure all fuel-burning appliances and vents in your home are inspected annually.
Symptoms of CO poisoning are similar to the flu without the fever. CO poisoning is often referred to as The Silent Killer. No colour. No odour. No taste.
If your CO alarm is going off continuously, call 9-1-1 and leave your home immediately. Do not open windows or ventilate your home. We will respond and test the levels of CO in your home.
CO alarms are required in homes that have an attached garage, a fuel-burning appliance, a fireplace, or heated air that comes from a fuel-burning appliance outside the home (for example, an appliance in a utility shed).
Examples of fuel-burning appliances that produce CO:
- water heater
- gas stove
- furnace
- dryer
- fireplace
- boilers
- space heaters
- portable fuel heater
- portable fuel fired generator
Compliance
In owner-occupied homes, the homeowner is responsible for complying with the CO alarm requirements in the Fire Code.
In rental homes, the landlord is responsible for complying with the CO alarm requirements in the Fire Code.
Buying and installing
When buying a CO alarm, look to see that the logo of a recognized standards testing agency is on the device to ensure they meet Canadian performance standards. Some examples of recognized standards testing agencies include:
- Canadian Standards Association (CSA)
- Intertek (ETL)
- Underwriters Laboratories of Canada (ULC)
Under the Fire Code, carbon monoxide alarms are permitted to be:
- Hardwired (connected directly to an electrical system)
- Battery-operated (portable or permanently mounted)
- Plug-in devices (plugs into a standard electrical outlet)
- Many devices on the market are combined units that include both a smoke alarm and carbon monoxide alarm in one device.
Follow the manufacturer's instructions to properly install the device.
