Lithium battery fires in the United States and Canada

Recently. The fire department in Douglas, Massachusetts, reported a commercial fire alarm at a solar energy storage facility at 45A Oak Street. The facility is equipped with a battery energy storage system (BESS). Firefighters arrived at the scene and found smoke coming out of a battery cabinet.

Douglas Fire Department said that the fire department immediately sounded a first-level alarm and adopted defensive strategies, including establishing a water supply system, deploying unmanned water pipes, and continuously monitoring the scene to prevent the fire from spreading to adjacent battery cabinets. After a comprehensive assessment, it was confirmed that the fire was limited to the failure of a single battery cabinet and did not spread to peripheral equipment. There is no leakage of toxic and harmful substances at the scene, and there is no threat to the fire at present.

On August 5, local time, a fire broke out in a high-rise shelter building operated by the municipal government in Etobicoke District of Toronto, Canada. The fire department received an alarm at 5:30 in the morning and rushed to 2180 Islington Avenue and found a lot of smoke on the seventh floor. With the help of the building's automatic sprinkler system, the fire was quickly extinguished. The accident caused no casualties, but one person was taken to hospital with unrelated injuries. The Toronto Fire Department confirmed to the media that the fire was related to a lithium-ion battery that was being charged. According to the Toronto Fire Department, there have been 76 fires involving lithium-ion batteries in Toronto so far this year, an increase of 35% over the same period in 2025. These fires have resulted in 2 deaths and 14 injuries.

In the face of the increasingly frequent thermal runaway crisis of lithium batteries, Shengsida must closely follow the actual situation of the industry and focus on "early detection, early intervention, less spread and disposal" to make deep products and services. The successful isolation of the Massachusetts single battery cabinet and the effective linkage of the Toronto sprinkler system confirm the absolute necessity of hierarchical protection and system coordination. We will continue to increase investment in the research and development of PACK-level fire extinguishing technology, using the "multi-sensor fusion (combustible gas + temperature + smoke)" system to achieve very early warning, combined with efficient and environmentally friendly fire extinguishing media, and strive to lock the fire in the initial and even gestation stage.

On the other hand, the 35% surge in lithium battery fire data in Toronto has sounded the industry alarm, which means that the safety boundary of energy storage fire protection is rapidly extending from large outdoor stations to industrial and commercial and urban densely populated areas. As an energy storage fire fighting enterprise, we should not only stay in the role of a simple "equipment supplier", but should keenly capture the needs of scene differentiation, optimize fire fighting and explosion suppression schemes for different application scenarios, and promote the upgrade from a single fire extinguishing device to an integrated system of "early warning-linkage-disposal-exhaust-isolation" to ensure that risks can be locked in a single cabinet, single cabin and single area at the initial stage of the accident.

Only by truly implementing product capabilities, system integration capabilities and on-site emergency service capabilities, can energy storage and fire protection companies not only be "responders after accidents" in the face of frequent lithium battery safety incidents, but also become builders of the safety base of the energy storage industry, Helping the entire energy storage industry to go more stable and farther.
