President Donald Trump, who has a penthouse condominium at Trump Tower, was in Washington at the time.
One firefighter was hospitalized with nonlife-threatening injuries and a building worker, who had an injury that was initially described as serious, was treated at the scene and declined further medical attention, the Fire Department said.
The fire department later tweeted that the blaze, which was located inside a Heating, ventilation, and air conditioning (HVA0 system, was soon “under control.”
Eric Trump, one of the president’s sons, said on Twitter that it was a small electrical fire in the cooling tower on the building’s roof.
“The New York Fire Department was here within minutes and did an incredible job,” the younger Trump said.
“The men and women of the #FDNY are true heroes and deserve our most sincere thanks and praise!”
The cause of the blaze is being investigated by the city fire marshal, a Fire Department spokesman said.
As firefighters battled the blaze, a plume of smoke spewed from the roof of the 68-story structure, which had been Trump’s primary residence before his election victory and inauguration nearly a year ago.
