The Winnipeg Fire Paramedic Service has been around the block with heaters this year.
In the first week of 2025, they’ve responded to at least four fires related to block heaters and extension cords. Block heaters keep cars running in the winter, but they can be dangerous if not used properly.
“Never plug in your vehicle inside a garage,” said Scott Wilkinson, Deputy Chief, Fire/Rescue Operations and Training, Winnipeg Fire Paramedic Service. “If a fire starts in your garage, it can spread quickly to your home or other nearby structures before you notice it, which can be extremely dangerous and cause a lot of damage.”
How to safely plug your car in
Here are a few tips from our safety experts and the Winnipeg Fire Paramedic Service:
-
Before using any extension cord, check it for damage. Inspect the ends and look for wear along the entire length of the cord. If the insulation around a cord is worn out and wires are showing through, don’t just tape it — replace it!
A cord can also be damaged even if it doesn’t look like it. If you’ve driven over your cord or pulled out of your driveway while still plugged in, it’s a good idea to get a new extension cord.
-
Only use extension cords rated for outdoor use and never exceed their wattage ratings.
-
Don’t plug in your car when it’s in the garage.
-
Don’t coil the cord — it can overheat and cause fires. Fully extend your cords when they’re in use.
-
Don’t run any cords under mats or rugs.
-
Don’t overload outlets or extension cords: one car per cord and per outlet.
