Toronto Fire Chief Jim Jessop has warned that lithium-ion battery fires in the city have surged by more than 200% since 2022. These incidents, often involving unregulated e-bike and e-scooter components, now represent the most significant public safety threat in the municipality.
A 200% spike in Toronto's battery-related emergencies
Toronto Fire Chief Jim Jessop has identified lithium-ion battery fires as the city's most pressing public safety risk, noting a surge of well over 200% since 2022. As reported by the source, this trend is largely driven by the proliferation of unregulated batteries used in e-bikes and e-scooters.
This escalation in Toronto mirrors a broader, alarming trend across North American cities struggling to manage the rise of micromobility. unlike the highly regulated batteries found in smartphones or electric vehicles, the batteries powering many consumer e-mobility devices often bypass strict safety standards, making them prone to catastrophic failure.
The 500-degree "blowtorch" and the 90-second escape window
The physical danger posed by these batteries is extreme, according to Randy Narine, president of Clean Core Research. narine warns that a failing battery can emit a jet of flame comparable to a 500-degree blowtorch, which can instantly ignite modern furniture made of polyurethane.
Time is the most critical factor for residents facing such an event. While a standard room fire might take 20 to 25 minutes to engulf a space,modern synthetic materials have reduced that window to five minutes; however, a lithium-ion battery failure leaves occupants with a mere 90 seconds to reach safety.
Toxic smoke and the "unheard of" cleaning of fire gear
The impact of these fires extends beyond immediate physical injury to the long-term health of first responders. Toronto Fire Services has had to implement entirely new protocols because the smoke produced by lithium-ion fires is uniquely toxic.
Jim Jessop noted that hazardous materials teams must now respond to every incident involving these batteries. Furthermore, the toxic residue requires a level of equipment maintenance that Jessop described as "unheard of," necessitating much deeper cleanig of firefighter gear than is typical for standard room-and-contents fires. Additionally, crews must remain vigilant as these fires can be unusually stubborn, sometimes restarting 24 to 36 hours after being extinguished.
Who will regulate the internet-sourced batteries?
Despite the clear danger, a significant regulatory gap remains regarding how these devices enter the Canadian market. Jessop pointed out that many of the problematic batteries are purchased via internet sites and do not meet any established safety standards, often being used in devices for which they were never intended.
Toronto has officially requested that the federal government establish national standards for battery imports, while also asking the province of Ontario to amend the Ontario Fire Code. Specifically, the city is exploring limits on the number of e-bikes allowed in individual apartment units . While Jim Demetriou of the Office of the Ontario Fire Marshal confirmed that code amendments are being explored, the speed of federal and provincial action remains an open question, and Health Canada has yet to announce specific new regulations.
