E-bike, scooter fires in Ottawa prompt warnings about safety

An e-scooter fire in Ottawahas officials urging people to ensure anyproducts with lithium-ion batteries meet Canadian electrical standards and are properly maintained.

Firefighters were called to a Cathcart Street row home complex in Lowertownaround 9 a.m. New Year's Day after two largerscooters were engulfed in flames while under a carport.

"I didn't know what exactly was burning," said Jason Leduc, a neighbour who tried todouse the blaze with afire extinguisher and ahosewhile his partner called 911.

"It was reaching to the ceiling and it was, I mean, a super hot fire," he said. "Itwas just an orange red hot blaze."

Thermal runaway

The cause of Sunday's fire, and whether it began with the e-scooters or if they were simply a casualty,is still being investigated.

Yet, as micromobility products anything from e-bikes and e-scooters tohoverboardsand e-unicycles increase in popularity,there's been an increase locallyin fires related to their lithium-ion batteries, with three such fires in Ottawa in the past three months.

Jason Leduc said he tried to douse the flames with a fire extinguisher before firefighters arrived at the Cathcart Street row home complex.

"The scooters are everywhere," said Gerry Gill, division chief of safety for Ottawa Fire Services. "People are using them for transport on city streets. They're using them for delivery. Some people are making a living with them."

They're oftencharged indoors,Gill said, which can increase the danger of "thermal runaway" a chemical chain reaction that occurswhen battery casings becomedamaged, losetheir insulationand lead to short-circuits.

What comes next, Gill said, can occur just as quickly as throwing a cigarette into a wastepaper basket.

"Thefire will spread faster than you can walk out of the room," he said.

Warning signs include bubbling, poppingor hissing sounds, followed by a white vapour cloud coming from the battery and a sickly sweet smell.

It's not just the fire that can be deadly: hydrogen from batteriescan mix withother chemicals to create hydrofluoric acid, said Gill, which is highly corrosive and candestroytissue and bone.

The commission sent a letter to 2,000 manufacturers in mid-December outlining safety concerns with products that don't meet health and safety standards.

BetweenJan. 1and Nov. 28 of last year, there were at least 208 fires oror incidents wheremicromobility products overheated, its letter said. Nineteen people died, including anine-year-old boy in New York, and at least 22 people were injured.

"There's no forced standard as of right now," said William Leishmen, who sells e-bikes at his ByWard Market shop Scooteretti. He said he's not surprised fires are on the rise.

Not just used in e-scooters

Lithium-ion batteries are found in many other products, including cell phones, laptops and electric toothbrushes. The New York City Fire Department said in an email to CBC it had investigated 320 fires resulting in 10 deaths and hundreds of injuries from products usingthe batteries during the same 2022 time span.

Gill saidthe best way to ensure a product remains safe isto follow the manufacturer's specifications, get it regularly inspected, not usean aftermarket charging cord and ensurethe battery is kept at room temperature and receives decent air circulation.

Most of all, people should not make any modifications themselves without visiting a reputable repair person.

"As a consumer, what's really, really important is do your homework," he said.

"If it looks like a great deal or you're dealing with a small company and the price looks attractive, if they don't have any certifications, by all means please avoid those products. You're doing yourself and your family a favour.
