Firefighters have expressed concerns regarding the challenges posed by lithium battery fires, especially in e-bikes stored in residential settings. Recent incidents in Toronto and Peterborough, Ontario, as well as a fire involving large storage batteries at a solar farm in Prince Edward Island, have highlighted the severity of the issue.
These incidents have prompted bans on electric bikes and cars in various buildings, public transit systems, and ferries, impacting individuals who rely on these modes of transportation. Additionally, the fear of lithium battery fires has caused some people to hesitate in adopting electric vehicles.
As Fire Prevention Week is observed this week with a focus on lithium batteries, it is crucial to understand the risks associated with these batteries and how to mitigate them effectively.
While Canadian fire departments do not consistently track lithium battery fires, estimates suggest that around 1,500 fires were started by lithium batteries in 600 communities across the country last year. These numbers are increasing alongside the proliferation of lithium battery-powered devices.
Lithium battery fires are more common in household devices like e-bikes and e-scooters, while incidents involving electric vehicles and energy storage batteries are relatively rare due to stringent safety measures and testing protocols. Although nationwide data on electric vehicle fires in Canada is limited, U.S. data indicates their rarity compared to fires in traditional gas-powered vehicles.
The causes of lithium battery fires can range from wear and tear leading to short circuits to overheating due to improper charging or external heat exposure. These fires can be challenging to extinguish due to their ability to burn hotter and faster than conventional fires, reaching thermal runaway and sustaining themselves by generating oxygen during combustion.
Moreover, lithium battery fires produce toxic substances and can reignite hours or even days later, posing additional risks to firefighters and the environment. Proper handling and extinguishing of these fires require specialized training and equipment, as traditional firefighting methods may not be effective.
To reduce the risk of lithium battery fires, it is essential to purchase certified batteries with safety features, charge devices correctly, and recycle damaged batteries at designated drop-off sites. By following these precautions, individuals can help prevent lithium battery fires and contribute to overall safety in their communities.
