Firefighters are expressing concerns over the dangers posed by hot, rapidly spreading fires in lithium batteries, particularly those in e-bikes stored in homes, as seen in recent incidents in Toronto and Peterborough, Ontario, and a significant fire at a solar farm in Prince Edward Island.
These concerns have led to restrictions on electric bikes and cars in various settings like buildings, public transit, and ferries, impacting individuals who depend on these modes of transportation. Additionally, such incidents have instilled apprehension among some individuals considering the adoption of electric vehicles.
As Fire Prevention Week is observed this week, the focus is on lithium batteries and the challenges they present in fire prevention. The risks associated with lithium battery fires are being highlighted, along with strategies to minimize these risks.
While official statistics on lithium battery fires in Canada are not consistently tracked, estimates from the Canadian Association of Fire Chiefs suggest that around 1,500 fires ignited by lithium batteries occurred across 600 communities in the country last year. The prevalence of lithium battery fires is higher in household devices like e-bikes and e-scooters.
Contrary to common lithium battery fires, incidents involving EV and energy storage batteries are infrequent due to rigorous testing and built-in safety mechanisms such as temperature sensors and cooling systems. The rarity of EV fires is evident in U.S. data, showcasing their uncommonness compared to fires in gasoline-powered vehicles.
Lithium battery fires are initiated by various factors, including damage to the battery leading to short circuits, overheating due to improper charging practices, or external heat sources. These fires pose unique dangers due to their ability to burn intensely and rapidly, self-generate oxygen, release toxic substances, and reignite even after being seemingly extinguished.
To reduce the risk of lithium battery fires, consumers are advised to purchase batteries with certified safety labels, charge devices correctly, and recycle batteries at designated drop-off sites. Proper handling and disposal of damaged batteries are crucial to prevent potential fire hazards.
In the event of a lithium battery fire, firefighting methods differ from traditional fires, with large quantities of water often required to cool the battery and prevent further damage. However, water may not effectively extinguish the fire and can prolong the burning process, necessitating specialized handling techniques.
Overall, awareness of lithium battery fire risks, proper precautions, and adherence to safety guidelines are essential to mitigate the potential dangers associated with these incidents.
