Firefighters have expressed concerns regarding the risks posed by high-temperature, rapidly spreading fires in lithium batteries found in e-bikes at private residences, such as incidents in Toronto and Peterborough, Ontario, along with a recent fire at a solar farm in Prince Edward Island.
The prevalence of lithium battery fires has resulted in restrictions on electric bikes and vehicles in various settings, including buildings, public transit, and ferries, impacting individuals dependent on these modes of transportation. Additionally, these incidents have instilled apprehension in some individuals about adopting electric vehicles.
During Fire Prevention Week, the focus is on lithium batteries and the challenges they present, emphasizing the importance of understanding and minimizing the associated risks.
Statistics on lithium battery fires in Canada reveal a growing trend, with an estimated 1,500 incidents reported last year across 600 communities, predominantly involving devices like e-bikes and e-scooters.
While fires involving electric vehicles and energy storage batteries are less common due to rigorous testing and safety features, concerns persist. Lithium battery fires can be triggered by factors such as physical damage, overheating from improper charging, or external heat sources, leading to potential hazards.
The unique dangers posed by lithium battery fires include their ability to burn intensely and rapidly, reach thermal runaway, generate their own oxygen, release toxic substances, and have the potential to reignite even after the initial fire is extinguished.
Fire departments face challenges in handling these fires, with limited training, equipment, and decontamination protocols in place. Extinguishing lithium battery fires often requires substantial amounts of water and specialized approaches due to the batteries’ characteristics.
To mitigate risks, consumers are advised to purchase certified batteries, charge devices properly with the correct chargers, and recycle batteries at designated drop-off sites to prevent disasters and environmental contamination. Damaged batteries must be handled with care and disposed of safely to avoid potential hazards.
