Several dozen vehicles go up in flames each winter in Manitoba due to a faulty extension cord or corroded blockheater plugs, according to Manitoba Public Insurance fire experts.
A cracked extension cord, or blockheater cord with a corroded plug can result in “electrical arching” which can quickly spark a fire, explained Clem Cormier, Manager of Manitoba Public Insurance’s Special Investigations Unit, which consists of three fire experts.
“Fire experts are specifically trained to determine the source of a fire,” said Cormier. “Many vehicle fires are the direct result of electrical arching, caused directly by a compromised cord or plug.”
Each year in Manitoba about 1,000 vehicles are damaged by fire ─ several dozen are the direct result of damaged extension cords or worn blockheater/in-car heater plugs. The majority of these fires take place in winter.
During bitterly cold winter temperatures, Manitobans will plug in their vehicles to heat various engine fluids (anti-freeze/oil), allowing for easier starting. Extension cords which are cracked or have exposed wires should be replaced, said Cormier.
“Many vehicle owners should take a few seconds to also inspect the block heater plug,” he says. “If the plug in is broken, or has obvious corrosion, it should be replaced immediately.”
Corrosion can be caused by exposure to moisture, dirt and road salts. With personal safety in mind, people are advised not to plug in their vehicles within a garage or any other enclosed structure.
Safety tips for extension cords/block heater plugs:
• Don’t drive over your extension cord. This can cause cracking/breaking during bitterly cold weather.
• Cover your block heater plug in with its protective cover.
• Unplug your block heater by using the hard, rubber end. Pulling on the electrical cord can cause breakage and potential electrical issues.
• Have your block heater cord inspected each fall by a qualified mechanic.
