Firefighters are expressing concerns over the dangers posed by lithium batteries, which are prone to hot, fast-burning fires that are challenging to extinguish. Recent incidents in Toronto, Peterborough, and a PEI solar farm have highlighted the risks associated with lithium battery fires. These concerns have led to bans on electric bikes and cars in certain buildings, public transit, and ferries, impacting those who rely on these modes of transportation. Additionally, some individuals have become hesitant to adopt electric vehicles due to fears of battery fires.

As Fire Prevention Week is observed, the focus is on lithium batteries and the risks they pose. Lithium battery fires have been on the rise, with an estimated 1,500 fires attributed to lithium batteries across 600 communities in Canada last year. These fires are most common in devices used in homes, particularly e-bikes and e-scooters. While fires involving electric vehicles and energy storage batteries are less frequent due to stringent testing and safety features, incidents still occur.

The unique nature of lithium battery fires makes them particularly hazardous. These fires can burn hotter and faster than conventional fires, reaching thermal runaway where chemical reactions intensify the blaze. Moreover, lithium batteries generate their own oxygen during a fire, making them challenging to extinguish using traditional methods. The fires also produce toxic substances that pose risks to firefighters and can reignite even days after the initial incident.

Efforts to mitigate the risks of lithium battery fires include purchasing certified batteries with safety features, following proper charging protocols, and recycling damaged batteries at designated drop-off sites. Firefighters are often ill-equipped to handle lithium battery incidents, highlighting the need for more training and specialized equipment. While water can provide cooling for lithium battery fires, it is not effective in extinguishing them, requiring alternative approaches to manage these incidents effectively.
