Firefighters have expressed concerns regarding the emergence of intense, rapidly spreading fires in lithium batteries, notably in e-bikes within residential settings in Toronto and Peterborough, Ontario, and in large storage batteries at a Prince Edward Island solar farm recently.
These incidents have prompted restrictions on electric bikes and cars in certain buildings, public transport, and ferries, impacting individuals dependent on these modes of transportation. Additionally, they have instilled hesitancy in some people considering electric vehicles.
During Fire Prevention Week, the focus is on lithium batteries, shedding light on the challenges posed by lithium battery fires and strategies to mitigate associated risks.
Although Canadian fire departments do not uniformly track lithium battery fires, the Canadian Association of Fire Chiefs estimates approximately 1,500 fires ignited by lithium batteries across 600 communities in the country last year, aligning with the surge in lithium battery-powered devices.
While lithium battery fires are more prevalent in household devices like e-bikes and e-scooters, incidents involving EV and energy storage batteries are infrequent due to stringent testing and safety features.
The unique characteristics of lithium battery fires, such as their ability to burn intensely and rapidly due to thermal runaway, make them particularly hazardous. Their capacity to generate oxygen internally and produce toxic substances like hydrogen fluoride and heavy metals further complicates firefighting efforts.
Firefighters often lack adequate training and equipment to handle lithium battery incidents effectively, underscoring the need for enhanced preparedness measures.
Extinguishing lithium battery fires typically requires substantial water volumes, significantly more than conventional fires. However, traditional firefighting methods may not suffice due to the batteries’ unique properties, necessitating innovative approaches.
To reduce the risk of lithium battery fires, consumers are advised to purchase certified batteries with safety labels, charge devices correctly, and recycle batteries at designated drop-off sites to prevent potential hazards.
Overall, understanding the nature of lithium battery fires and adopting proper safety practices are crucial in minimizing the associated risks and ensuring public safety.
