The incident occurred in northeast Dallas
Dallas (CNN) — A firefighter was trapped early Monday in a six-alarm blaze at a Dallas condominium complex, the city's fire department said.
A search is on for the firefighter, one of a team responding to the blaze at the Hearthwood North Condominiums, in northeast Dallas.
"When firefighters arrived at the location, there was lots of smoke coming from the roof of a three-story condominium building," the department said. "An offensive fire attack was initially attempted, but the fire was growing too quickly and caused them to have to move out for a defensive attack."
The fire has been classified as a six-alarm blaze for several reasons, the department said, including the search.
At least five residents have been rescued, the department said. One resident was treated for smoke inhalation at the scene. No other injuries have been reported, and the Red Cross has been called to help displaced residents.
