Calgary fire officials warn against dangers of lithium-ion batteries

Fire officials are urging Calgarians to recharge batteries before they go dead in an awareness campaign highlighting the dangers of lithium-ion batteries.

The campaign aims to teach residents how to use the batteries safely and cautions that an effort bring back to life a “zombie” battery is not safe.

Lithium-ion battery fires are rising in the city, the Calgary Fire Department (CFD) warns, adding they are now commonly found in a number of devices like scooters, e-bikes, phones, laptops, and power tools.

“All lithium-ion batteries, and in particular, uncertified ones, have the potential to overheat, catch fire and cause explosions, with little to no warning,” says Fire Chief Steve Dongworth in a statement.

“These fires can quickly reach temperatures over 500 C, producing toxic gases and dangerous smoke, which often can’t be put out with water.

The CFD is urging people to only charge with certified and lab tested products, and advise everyone to take the following steps to reduce the risk of fires:

1. Only use certified lithium-ion batteries, chargers and cords that have been tested by national testing laboratories. Look for the ULC or CSA label on products.
2. Don’t use batteries that are hot, look swollen, are punctured or leaking, or are emitting gases that look like white or grey smoke.
3. Don’t leave batteries charging overnight or in places that block exits, such as doorways and hallways. In the event of a fire, your escape route will be blocked.
4. Avoid using your batteries in extreme hot and cold temperatures. Ideally, batteries should be kept between 0 and 40 degrees Celsius. Keep batteries away from heat sources or flammable materials, which could increase the likelihood of fires.

Anyone who sees a battery smoking or on fire is being asked to leave the area and call 911.

“Lithium-ion battery fires give off toxic gases and burn extremely fast and hot, making them difficult to put out,” warns the CFD. “These batteries can create a large fire very quickly so you may have less than a minute to get out safely.”

Calgarians should not throw lithium-ion batteries in the garbage — and instead separate them from other trash and bring them to a recycling retailer.

Residents can drop off batteries for free at one of the city’s Eco-Centres.
