Firefighters rescued three people from the roof of a two-story building in Tokyo after a battery exploded and sparked a fire on Monday [1].
The incident highlights the volatile nature of battery failures in residential areas, where rapid combustion can trap occupants in multi-story structures.
The blaze began around 1 p.m. in Fujimi-cho, located in Itabashi Ward [1]. The building is situated approximately 800 meters west of Itabashi-honcho Station on the Toei Mita Line [2]. According to the Tokyo Fire Department, the fire originated on the second floor of the two-story structure and spread across an area of about 50 square meters [1, 2].
Emergency services deployed 27 fire-engine units to contain the flames [1]. During the incident, three residents were unable to exit the building in time and sought refuge on the roof [1]. Investigative sources said the individuals were rescued and remained conscious following the operation [2].
Authorities are focusing on the cause of the ignition. An investigative source said the battery had exploded [2]. The scale of the response, including the dispatch of nearly 30 units, underscores the intensity of the fire and the risk posed by the chemical nature of the explosion.
Local residents in Fujimi-cho reported seeing smoke emanating from the second floor before the rescue operation was completed. Firefighters worked to secure the perimeter and extinguish the remaining hotspots to prevent further spread to adjacent buildings in the residential block [1, 2].
“The battery had exploded”
This incident underscores the increasing safety risks associated with high-energy density batteries in residential settings. The fact that a single battery failure could necessitate the deployment of 27 fire-engine units suggests a high thermal load and rapid fire spread, emphasizing the need for specialized firefighting tactics and stricter storage regulations for electronic components in urban housing.
