Carbon monoxide alarms can save your life

Invisible, tasteless and odourless – carbon monoxide is also known as a silent killer.

City services | October 31, 2024

November 1 to 7 is Carbon Monoxide Awareness Week and Mississauga Fire and Emergency Services (MFES) is raising awareness about carbon monoxide (CO) poisoning and the importance of having a working carbon monoxide alarm at home.

Known as the “silent killer,” carbon monoxide is a harmful gas you can’t see, taste or smell. It’s harmful to humans and pets, and exposure can lead to carbon monoxide poisoning, which can be fatal. Carbon monoxide is created from the incomplete burning of fossil fuels such as natural gas, propane and wood. The main source of carbon monoxide in your home is a fuel-burning appliance/heater, a fireplace or an attached garage.

On average, Ontario homes have between 4 to 6 fuel-burning appliances that produce carbon monoxide such as a stove or furnace.

Carbon monoxide alarms are required by provincial law in all homes that have fuel-burning appliances such as a stove or furnace, heaters, a fireplace or an attached garage. The carbon monoxide alarm must be located outside all sleeping areas. This applies to all homes including condos, apartments, townhouses and semi-detached, detached homes, cottages and rental properties.

For carbon monoxide alarms, be sure to:

  • Install them outside of all sleeping areas
  • Test them monthly
  • Replace them every 10 years
  • For extra protection, install the alarms on every level of your home

Ensure all fuel-burning appliances and vents in your home are inspected annually.
