Three people had minor injuries after a blaze broke out in a cooling unit on a Trump Tower roof deck Monday morning, according to FDNY officials.

FDNY Chief Roger Sakowich said one firefighter was hurt when debris fell on top of him, and an engineer who tried to douse the flames himself had injuries but refused treatment after the blaze that broke out on President Donald Trump's namesake skyscraper at East 57th Street and Fifth Avenue at 6:58 a.m. The department later said a third person was also treated on the scene.

Trump, who has lived in a penthouse apartment for 30 years before, was in Washington at the time of the blaze. His son, Eric Trump tweeted out thanks for first responders.

There was a small electrical fire in a cooling tower on the roof of Trump Tower. The New York Fire Department was here within minutes and did an incredible job. The men and women of the #FDNY are true heroes and deserve our most sincere thanks and praise! https://t.co/xuTmq1GBbj — Eric Trump (@EricTrump) January 8, 2018

Sakowich said U.S. Secret Service agents noticed the blaze, which started in a cooling unit, which at this time of year are equipped with heaters. The flames came out of a vent, he said.

Cameras on the top of Rockefeller Center, about seven blocks away, showed firefighters crowding around on the top of the building as smoke emitted from one corner of the roof about 7:30 a.m.

By 8 a.m., the smoke had cleared and firefighters appeared to have left the scene, footage showed.

Sakowich said the fire remains under investigation.
