Be aware of the dangers of CO


Carbon monoxide (CO) is a deadly gas that is extremely difficult to detect without some sort of aid.

CO poisoning is the number one cause of unintentional poisoning deaths in Canada. If you have an attached garage, wood or gas fireplace, furnace, water heater or range / stove, you need a CO alarm.

CO Alarm Checklist: 

  • It has a national testing agency sticker
  • The manufacturer’s instructions were followed for installation and maintenance
  • One is installed outside or in each sleeping area and on every level of the home
  • It is clear of dust and debris
  • It is plugged all the way into a working outlet, or has working batteries


Stay safe and be aware of the dangers of CO

Heating Safety

  • Only use appliances indoors if they are approved for indoor use
  • Have fuel and wood-burning appliances inspected every year by a licensed technician
  • Make sure all vents and chimneys are connected, vent their fumes to the outside, are maintained according to the manufacturer’s instructions, and are not blocked
  • Never idle your car in the garage, even if the garage door is open
  • Never use generators, camp stoves, or gas or charcoal grills indoors
  • Never use a gas oven to heat your home
  • Never use gasoline-powered engines in enclosed spaces
  • Ensure that all exterior vents are clear of snow


Portable Generator Safety

  • Follow the manufacturer’s instructions for use and maintenance
  • Use outdoors on a stable surface and away from windows and vents
