Firefighters are expressing concerns over the rapid, intense, and challenging-to-extinguish fires caused by lithium batteries. Recent incidents involving e-bikes in residential areas like Toronto and Peterborough, Ontario, and a large storage battery fire at a Prince Edward Island solar farm have raised alarms.
The rise in lithium battery fires has led to restrictions on electric bikes and cars in certain buildings, public transportation, and ferries, impacting those who rely on these modes of transport. Additionally, these incidents have instilled hesitancy in some individuals about adopting electric vehicles.
As Fire Prevention Week is underway, focusing on lithium batteries as the central theme, attention is drawn to the complexities of lithium battery fires and strategies to mitigate associated risks.
According to estimates from the Canadian Association of Fire Chiefs, approximately 1,500 fires caused by lithium batteries occurred across 600 communities in Canada last year, with a notable increase in incidents related to e-bikes and e-scooters.
While electric vehicle (EV) and energy storage battery fires are less common due to stringent testing and safety features, concerns persist. Lithium battery fires can be triggered by factors such as wear and tear, damage, overheating, or improper charging methods.
Lithium battery fires present unique challenges as they burn hotter and faster than conventional fires, can generate their own oxygen, release toxic substances, and have the potential to reignite even days after being extinguished. Firefighters often lack adequate training and equipment to handle these incidents effectively.
Handling and extinguishing lithium battery fires require specialized approaches, as traditional methods like water spraying may not suffice. Experts recommend allowing the fire to burn out in many cases, especially for larger energy storage batteries.
To reduce the risk of lithium battery fires, consumers are advised to purchase certified batteries, charge devices properly, and recycle damaged batteries at designated drop-off sites. Taking precautions such as using the correct charger, avoiding modification of batteries, and proper disposal can help prevent potential fire hazards associated with lithium batteries.
