Firefighters raced to a five-story walk-up in the Bronx's Norwood neighborhood on Wednesday after an explosion and heavy smoke sent flames tearing through the second and third floors of 374 East 209th Street, quickly escalating into a four-alarm fire. At least one person was severely injured and rushed to a nearby hospital, and fire commanders urged residents nearby to stay indoors and keep their windows shut as smoke spread through the block.
According to CBS News, crews were dispatched just before 12:30 p.m. Wednesday after callers reported the explosion, arriving to find flames already climbing through the building's upper floors. Paramedics rushed the injured victim to the hospital as commanders repeated the advisory for neighbors to shelter in place with their windows closed.
The FDNY confirmed on social media that units were operating at a four-alarm fire along East 209th Street. Under FDNY protocol, a four-alarm designation means incident commanders have requested additional resources four separate times, typically mobilizing between 20 and 39 emergency vehicles and up to 170 firefighters and medical personnel, according to fire service guidelines cited by Desert Fire.
Aging Walk-Up, Suspected Battery Spark
Property records reviewed by StreetEasy show the building dates to 1926 and holds 27 rental units spread across its five stories. Aging multi-family walk-ups like this one are common throughout Norwood, and the tight floor plans typical of that housing stock can let fire spread quickly enough to demand a response as large as Wednesday's.
Emergency dispatch reports cited by Cedar News indicate the fire began on the third floor and was suspected to have been triggered by an exploding lithium-ion battery. That cause has not been officially confirmed, and it remains unclear whether the battery involved met UL safety certification standards.
A Recurring Citywide Hazard
New York City apartment building owners are required to distribute fire safety rules warning tenants never to charge e-bikes overnight, run extension cords to lithium-ion batteries, or plug devices in near exit pathways, under an official bulletin from the City of New York. A separate end-of-year report from the City of New York, released in December, credited aggressive inspections, public education campaigns, and e-bike safety task forces with cutting battery fire deaths citywide by 67% between 2023 and 2024.
Even with that progress, lithium-ion batteries have caused more than 800 fires, 30 deaths, and 400 injuries across New York City since 2022, according to FDNY statistics compiled by Autonocion. If the battery theory behind Wednesday's fire holds up, it would add to that toll in a Bronx neighborhood already grappling with repeated fire emergencies this year.
Another Blaze on an Already Troubled Stretch
Firefighters responded to an earlier Norwood fire on the same block in March, when a top-floor apartment fire at 3345 Decatur Avenue injured a resident and a firefighter. Just blocks away on Briggs Avenue, crews battled another Briggs Avenue blaze in July, and a lithium battery ignited a similar Morrisania e-bike fire that same month. Bronx firefighting resources have also been strained this year — a fire inside the FDNY Engine 79/Ladder 37 firehouse on Briggs Avenue in March injured 14 firefighters and temporarily disrupted local emergency response, according to CTIF.
FDNY had not released an updated condition for the injured victim as of Wednesday evening, and it remains unclear whether residents of the building will face long-term displacement while repairs are made.
