FDNY’s ‘fire(works) lighters’

They may be New York’s Bravest, but some of them sure aren’t New York’s brightest.

In a Brooklyn neighborhood overrun with nightly illegal fireworks, one resident learned that some of the pyrotechnic aficionados are none other than FDNY firefighters.

The 33-year-old Crown Heights resident said he and his wife were passing by Ladder Co. 123 on St. Johns Place near Schenectady Avenue at about 11:30 p.m. Tuesday when he saw a group of firefighters ignite what appeared to be a fountain fireworks display.

“I thought it was young kids lighting it. And there are. But then I see the firefighters doing it — they should know better,” the man, who asked his name not be revealed, told The Post.

Video he recorded at the scene shows the fireworks spraying sparks into the night air from a device on the street.

The man said one of the firefighters confronted him about video-recording the display — causing him to question whether they actually knew that what they were doing was “absurd,” he said.

“As public servants, I feel like they should know better than to light fireworks at 11:30 at night. It’s completely brazen wantonness,” the man said.

The use of illegal fireworks has skyrocketed across the city and is prevalent in neighborhoods like Crown Heights.

City officials reported a 4,000 percent surge in fireworks complaints during the first two weeks of June, with 849 reports to the city’s 311 hot line between June 1-14 — up from just 21 over the same time span last year.

It’s gotten so bad in Crown Heights that the man who video-recorded the firefighters says he and his family are hightailing it out of the city to a vacation home so his children aren’t terrified.

The FDNY said it is investigating the incident.
