A discarded cigarette butt triggered a fiery explosion in the Bronx that injured seven firefighters, officials confirm.
The incident occurred on November 6, 2025, in the Longwood section of the Bronx, greater New York area, where FDNY crews were responding to a reported gas leak. Surveillance footage reviewed by investigators shows a cigarette igniting flammable vapours near a building entrance, moments before a powerful blast erupted.
What Happened
Firefighters had arrived at the scene to investigate a suspected gas leak when the explosion occurred. The blast sent debris flying and caused partial structural damage to the building. Seven firefighters were injured, with at least one suffering serious burns. All were transported to local hospitals and are expected to recover.
Ignition Source Identified
According to FDNY officials, video evidence shows a person discarding a lit cigarette near the building’s entrance. Seconds later, the explosion occurred—suggesting that gas vapours had accumulated in the area, creating a volatile environment. Investigators believe the cigarette acted as the ignition source.
Safety and Accountability
The incident has reignited concerns about public awareness of gas safety and open flame risks, especially in densely populated urban areas. FDNY Commissioner Laura Kavanagh emphasized the importance of reporting gas odours immediately and avoiding any ignition sources near suspected leaks.
Con Edison confirmed that crews had been dispatched to the area prior to the explosion and are cooperating with the investigation. The utility company is reviewing pipeline integrity and leak detection protocols.
Editors Note: Con Edison (short for Consolidated Edison, Inc.) is not part of the FDNY—they are a private utility company that provides electricity, gas, and steam services to much of New York City and Westchester County.
In emergency situations like fires, explosions, or gas leaks, Con Edison works alongside the FDNY to:
-
Shut off utilities to prevent further danger
-
Investigate causes of electrical or gas-related incidents
-
Repair damaged infrastructure after the scene is secured
Video Evidence and Investigation
The footage, obtained from a nearby business, is being analyzed by fire marshals and NYPD investigators. Officials have not yet identified the individual who discarded the cigarette, but charges may be considered depending on the outcome of the inquiry.
