An e-bike battery ignited inside a Sunset Park apartment just after midnight on Jan. 1, bringing hazmat crews to 550 51st St. and leading to a partial vacate order for part of the building. Firefighters quickly knocked down a small living-room blaze and no injuries were reported, but the early-morning scare left neighbors rattled and building inspectors busy.
Fire response and immediate impact
According to News 12 Brooklyn, FDNY got the call at about 12:32 a.m. and found a fire on the third floor. Crews had it under control by around 1:35 a.m. The outlet reports that firefighters pulled a charred e-scooter out to the sidewalk and placed two FDNY drums, specialized containers used to isolate lithium-ion batteries, at the building entrance. Fire marshals have opened an investigation into the incident.
What a partial vacate order means
A partial vacate order limits occupancy in only part of a building when there is a hazardous condition, such as inadequate fire protection or unsafe storage that creates an immediate risk. The Department of Buildings explains that tenants affected by a vacate should reach out to borough construction enforcement or HPD for relocation and rehousing help while repairs, inspections or safety clearances move forward.
Neighbors saw the response
A neighbor across the street, Juan, told News 12 Brooklyn, “I saw when the firemen came out with the e-bike, and everybody noticed it was the battery from the bicycle.” He said the scene highlighted ongoing worries about lithium-ion batteries being stored inside apartments and near shared exits.
City policy and the larger trend
The fire comes as city agencies continue pushing measures to curb lithium-ion battery blazes, including a program that would allow FDNY-approved sidewalk battery-charging cabinets so charging can happen outside apartments. The expansion, detailed by Gothamist, is part of a broader response officials say is needed after hundreds of battery-related fires in recent years.
Safe handling and disposal
Officials are again reminding New Yorkers not to charge or store large e-bike batteries inside apartments or near exit routes, and to secure terminals with tape or place batteries in bags before drop-off. Guidance on safe disposal and special-waste drop-off locations is available from the Department of Sanitation. Residents can report hazardous battery conditions to the city through 311.
Investigation continues
Hazmat crews cleared the scene after the fire, and inspectors remained on site as fire marshals continued to investigate what sparked the battery and when the partial vacate order can be lifted. City officials did not immediately release additional details and said neighbors will be updated as findings are confirmed.
