Officials urge proper lithium-ion battery use after 'concerning rise' in fires

Article content

Toronto Fire has launched a second public safety campaign to raise awareness about the growing fire risks associated with lithium-ion batteries.

In 2024, firefighters responded to 76 fires caused by lithium-ion batteries, a 38% increase from 2023 (55 fires) and a 162% increase compared to 2022 (29 fires).

This year, Toronto Fire has already responded to 43 blazes caused by lithium-ion batteries, one of which was a significant high-rise fire with multiple injuries to both occupants and first responders.

During the subsequent fire investigation, a large quantity of lithium-ion batteries were discovered within the affected unit and determined to have significantly contributed to the fire’s growth and the amount of smoke that had spread throughout the building.

“We’re seeing a concerning rise in fires caused by lithium-ion batteries, many of which are preventable,” said Toronto Fire general manager Chief Jim Jessop in a statement.

“This campaign is about giving residents the knowledge they need to stay safe. Fire prevention is a shared responsibility (and) together we can protect our homes, neighbours and our city. Toronto Fire Services will continue to advocate for the necessary regulatory changes to reduce this public fire safety risk in our city.”

Lithium-ion batteries power many everyday devices, including smartphones, laptops, e-bikes and toys, and are generally safe, but can become dangerous if damaged, tampered with or improperly charged.

Many of the recent fires were caused by attempts to modify or extend the life of the batteries.

Some key safety tips:

— Keep the lithium-ion battery in sight while charging;

— Never tamper with or modify a battery;

— Only use certified, manufacturer-approved batteries and chargers;

— Stop using a lithium-ion battery and contact the manufacturer if there are any of the following problem signs: Strange odours, discolouration, excessive heat, change in shape, leaking or odd noises.
