An electric vehicle, specifically a Nissan Leaf, sparked an emergency response when it began to emit smoke while charging in a King Soopers parking lot. The owner quickly disconnected the vehicle from the charging station, but the smoke continued, leading to the immediate intervention of local fire departments.
Firefighters from Engine 11 and Hazmat 38 arrived at the scene and discovered the electric vehicle in a state of “thermal runaway.” This term refers to a situation where the vehicle’s lithium-ion batteries overheat and ignite in a sequential manner. Although there were no active flames initially, the situation necessitated careful observation.
Due to the direction of the wind, which was pushing the smoke towards nearby businesses, a precautionary evacuation of the adjacent strip mall was carried out. Fire crews established a secure perimeter and implemented exposure protection measures to prevent the potential spread of fire to nearby structures.
The fire department, in collaboration with the Environmental Protection Agency (EPA), adopted a strategy that allowed the fire to burn while controlling potential hazards. This approach is designed to minimize environmental impact by avoiding the use of water, which can combine with combustion byproducts to produce toxic runoff.
Despite the challenging circumstances, firefighters successfully managed the situation. The smoke was directed straight into the atmosphere, mitigating local air quality concerns. Eventually, the fire was extinguished using a combination of water and foam to suppress vapors and manage any remaining flames.
Owners of electric vehicles were advised to comply with manufacturer recalls and to use reputable charging stations. In case of smoke or other issues, they should disconnect the vehicle and immediately contact emergency services.
After the fire was contained, the vehicle was prepared for transport to a specialized tow yard equipped to handle electric vehicles. These facilities are designed to manage any further incidents of thermal runaway safely.
Firefighters’ gear, which was exposed to toxins during the operation, was sent for specialized cleaning to ensure safety and compliance with health standards. This process involves thorough decontamination and testing to determine the gear’s continued usability.
