A Brooklyn business owner fell to his death trying to flee a devastating fire Wednesday morning, FDNY officials said.

Seven others were injured in the 3:30 a.m. Prospect Heights blaze, which broke out in the building’s ground-floor hardware store at 265 Flatbush Ave., officials said.

Deli-owner Bassam Awad, 46, escaped his fourth-floor apartment — but fell from his fire escape as 250 firefighters battled the five-alarmer for two hours.

“You literally heard women screaming, ‘Help, it’s burning,’” said neighbor Veronica Hossain who called the chaotic scene “heartbreaking.”

“He was a great man, what can I say? He was a great man, I love him very much,” his 36-year-old brother, Abdurahman, said, before breaking down in tears.

Awad’s mother was among three people critically injured in the blaze.

His wife, Ralima, and two sons also suffered burns and were rushed to area hospitals.

The fire was sparked by faulty electrical wiring on a neon light outside the hardware store, FDNY officials said.
