Firefighters are expressing concerns over the dangers posed by lithium battery fires, which have proven to be hot, fast-burning, and challenging to extinguish. Recent incidents involving e-bikes in residential areas in Toronto and Peterborough, Ontario, as well as a fire at a solar farm in Prince Edward Island, have highlighted the risks associated with lithium batteries.
The increasing frequency of lithium battery fires has prompted restrictions on electric bikes and cars in various settings, such as buildings, public transit, and ferries. These restrictions have affected individuals who rely on these modes of transportation and have also created skepticism among some about adopting electric vehicles.
As Fire Prevention Week is currently observed, the focus is on lithium batteries and the unique fire hazards they present. Understanding the complexities of lithium battery fires and implementing strategies to mitigate these risks are crucial steps in preventing such incidents.
Lithium battery fires are a growing concern, with an estimated 1,500 fires attributed to lithium batteries across 600 communities in Canada last year. These incidents are more common with devices like e-bikes and e-scooters found in households.
While electric vehicle (EV) and energy storage batteries undergo rigorous testing and incorporate safety features like temperature sensors and cooling systems, incidents involving them are relatively rare. Data from the U.S. indicates that EV fires are significantly less common compared to fires in gasoline-powered vehicles.
One key factor contributing to lithium battery fires is the formation of a short circuit in the battery, often caused by wear and tear or physical damage. Overcharging, improper charging, or exposure to external heat sources can also trigger fires in lithium batteries.
Lithium battery fires are particularly hazardous due to their ability to burn hotter and faster than conventional fires. These fires can sustain themselves by generating oxygen and releasing toxic substances, posing challenges for firefighters in extinguishing them.
To reduce the risk of lithium battery fires, consumers are advised to purchase certified batteries with safety labels and avoid modifying batteries for quicker charging. Proper charging practices, including using the correct charger and charging on non-combustible surfaces, can help prevent incidents. Recycling damaged batteries at designated drop-off sites is recommended to ensure safe disposal and prevent potential hazards.
Overall, understanding the causes and dangers of lithium battery fires, along with adopting safe handling practices, is crucial in preventing these hazardous incidents.
