Every day, on the streets of Montreal, we encounter citizens using devices equipped with lithium-ion batteries. These devices present a particular danger in case of fire, as the scale of these fires and the hazardous products released pose risks for our firefighters. Additionally, these devices are often stored inside buildings, which represents a significant risk in case of fire. The Montreal Fire Department wanted to implement work procedures to respond effectively and safely to this type of call. We will present the results of our work and discuss the challenges we encountered, the tools we chose, the call statistics, and the issues related to battery recovery.
