The Calgary Fire Department (CFD) set out to raise awareness of the serious risks associated with lithium-ion batteries through a new Halloween-themed public safety campaign.
Featuring a “zombie” theme, the initiative warned Calgarians that “Damaged Batteries Should Stay Dead,” underscoring the dangers of attempting to revive or repair damaged or modified lithium-ion batteries.
Lithium-ion batteries have become essential in modern life, powering everything from smartphones and laptops to e-bikes and power tools. But as these batteries become more widespread, so does the risk of fire. In Calgary, fires caused by lithium-ion batteries are on the rise, posing a hazard in many households.

“All lithium-ion batteries, and in particular, uncertified ones, have the potential to overheat, catch fire, and cause explosions, with little to no warning,” warned Calgary Fire Chief, Steve Dongworth, in an announcement. “These fires can quickly reach temperatures over 500 degrees Celsius, producing toxic gases and dangerous smoke, which often can’t be put out with water. We want to encourage Calgarians to charge these batteries safely and only use certified, lab-tested products.”

In September, a Port of Montreal terminal container filled with 15,000 kilograms of lithium batteries caught fire and produced heavy smoke for some 12 hours, prompting authorities to issue a shelter-in-place order.
To reduce fire risk, the CFD urges people to follow these safety guidelines:
- Use certified lithium-ion batteries, chargers, and cords that have been tested by national labs. Look for the ULC or CSA label.
- Do not use batteries that are hot, swollen, punctured, or leaking gas or smoke.
- Avoid charging batteries overnight or in locations blocking exits.
- Keep batteries at moderate temperatures (0-40 degrees Celsius) and away from heat sources or flammable materials.
In case of a lithium-ion battery fire, the CFD advises residents to evacuate immediately and call 911, rather than attempting to extinguish the fire themselves. These fires can burn intensely and emit toxic gases, requiring quick action to get to safety.
Proper Battery Disposal
To prevent fires at waste facilities, lithium-ion batteries should never be thrown in the trash. Calgarians are encouraged to bring used batteries to one of the city’s Eco Centres or other recycling locations, listed on recycleyourbatteries.ca.
