Firefighters are expressing concerns about the challenges posed by lithium battery fires, particularly in e-bikes at homes in Toronto and Peterborough, Ontario, as well as in large storage batteries at a solar farm in Prince Edward Island. These incidents have prompted restrictions on electric bikes and cars in various settings, impacting public transit and ferry services. Such issues have also instilled hesitancy among some individuals regarding the adoption of electric vehicles.
As Fire Prevention Week is observed, the focus is on lithium batteries due to their fire risks. The prevalence of lithium battery fires is on the rise, with an estimated 1,500 incidents reported across 600 Canadian communities last year. The most common occurrences involve devices like e-bikes and e-scooters found in residential settings. In contrast, electric vehicle (EV) and energy storage battery fires are less frequent due to stringent testing and safety mechanisms in place.
These fires are primarily caused by factors such as wear and tear, physical damage, overheating from incorrect charging methods, and exposure to external heat sources. Lithium battery fires burn hotter and faster than conventional fires, reaching thermal runaway that can trigger explosive reactions. They produce their oxygen, making traditional firefighting methods ineffective. Additionally, toxic substances are released during these fires, posing health risks to firefighters and necessitating thorough decontamination procedures.
Addressing lithium battery fires requires proper handling techniques, including avoiding water-based extinguishing methods that can exacerbate the situation. It is often recommended to allow the fire to burn out naturally in the case of large energy storage batteries. Safety measures to reduce the risks associated with lithium batteries include purchasing certified batteries, charging devices correctly, and recycling damaged batteries at designated drop-off sites.
Ensuring proper battery management practices and adhering to safety guidelines can help mitigate the dangers posed by lithium battery fires and protect both individuals and the environment.
