Stay Safe: Prevent lithium-ion battery fires

With lithium-ion battery fires on the rise, Westmount Public Safety reminds residents of simple precautions to prevent incidents involving common household items.

Did you know that everyday items like your smartphone, laptop, leaf blower or e-bike can start a fire or set off an explosion? Many devices we use in our day to day life contain lithium-ion batteries, which can pose a real hazard. Without the proper precautions, these batteries can ignite and release a flammable gas that may cause an explosion. In fact, fires involving lithium-ion batteries have been increasing every year in the Montreal area, with the Service de sécurité incendie de Montréal (SIM) reporting over 40 cases in 2024.

An incident can happen to anyone. Stay safe by abiding by these best practices:

  • When charging your device:
    • Remain alert, such as by avoiding charging your devices while you sleep;
    • Do not charge longer than necessary to avoid overheating or damaging the battery;
    • Use manufacturer-approved chargers that meet Canadian electrical standards.
  • At all times:
    • Avoid exposing your battery to heat sources, such as in a locked car on a summer day;
    • Dispose of old batteries and hazardous waste at an ecocentre;
    • Ensure your smoke detectors are in good working order and that you have a plan in case of an emergency.
