Electrical fire safety
Electrical equipment is a top cause of home fires in Ontario. Help prevent these types of fire with the following advice.
Performing electrical work
- Hire a licensed electrical contractor for all electrical work. In Ontario, these professionals are authorized by the Electrical Safety Authority.
- Make sure any electrician hired has a valid certificate of qualification from Skilled Trades Ontario.
- Find hidden hazards and request an inspection by a qualified professional when buying, selling, or renovating a home.
Extension cords and outlets
- Use extension cords only as a temporary fix. If more power is needed, have a licensed electrician install new outlets.
- Plug large appliances, like air conditioners or refrigerators, directly into a wall outlet and avoid extension cords or power bars.
- Avoid "octopus outlets" and don’t plug many items into one spot. This can overload the circuit and start a fire.
- Do not "daisy chain" power sources by plugging power strips or extension cords into one another. This can cause overheating and creates a fire hazard.
- Always plug power strips directly into a wall outlet.
- Never run electrical cords under rugs or carpets. Walking on them can damage the wires, and heat cannot escape.
- Check cords often for cracks or fraying. Replace any damaged cords immediately.
- Don’t push furniture tightly against plugs as it can damage the cord and outlet.
Protection from water and shocks
- Make sure ground fault circuit interrupters are installed in bathrooms, kitchens and garages when within 1.5 metres (5 feet) of a water source. These special outlets shut off the power if they detect a shock hazard.
- Keep all power bars and cords away from water.
- Keep the covers on outdoor outlets closed to protect them from the weather.
Electronics and appliances
- Only buy or use electronics and appliances that have a recognized Canadian certification mark (i.e. ETL, UL or, CSA).
- Canadian Standards Association (CSA)
- Underwriters Laboratories of Canada (ULC)
- Electrical Testing Laboratories (ETL)
- Check that all 3-prong plugs are in good shape before purchasing. The third prong keeps the appliance grounded and safe.
