Prevent an auto fire: Check your extension and block-heater cords

On average, about 1,000 vehicle fire claims are opened with Manitoba Public Insurance yearly. Of that total, about 10 per cent of those fire claims are related to faulty extension or block-heater cords.

A cracked extension cord, or block heater cord with a corroded plug, can result in an electrical failure which can quickly spark a fire. The majority of these fires take place in winter as temperatures drop.

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.
  • With personal safety in mind, people are advised not to plug in their vehicles within a garage or any other enclosed structure.
