A three-alarm fire ripped through a Staten Island home early Friday, injuring nine firefighters, officials said.

The blaze at a two-story home at 8 Holly Avenue in Great Kills broke out at about 3 a.m., with fire raging through its roof. A total of 138 firefighters from 33 units responded to the scene and brought the fire under control within two hours, FDNY officials said.

The injured firefighters, who had minor injuries and are expected to recover, were taken to area hospitals, an FDNY spokesman said, adding that no one inside the home was hurt.

Four people inside the residence managed to escape before firefighters responded, WABC reports.

“It was really scary and fast [moving],” a neighbor told the Staten Island Advance.

The cause of the fire remains under investigation, FDNY officials told The Post.

The blaze ripped through the home’s basement, as well its first and second floors before breaching the roof, according to an FDNY Twitter feed.

The house appeared to be completely gutted in photos taken at the scene early Friday after the fire was extinguished, with piles of debris, including furniture, strewn across the front lawn.
