Firefighters responded Monday morning to a three-alarm blaze at a multi-level residential building in downtown Oakland. The blaze was reported just before 7:10 a.m. at a five-story, 47-unit building building on 19th Street and Broadway, near the 19th Street BART station. The Oakland Fire Dep artment told NBC Bay Area that three people were transported to the hospital to be treated for non-life-threating smoke inhalation. One firefighter suffered a minor injury. OFD Chief Damon Covington said the damage to the building is extensive after the fire started on the second floor before quickly moving through most floors. Businesses on the first floor also suffered damaged. Oakland legendary rapper Mistah F.A.B. owns the Dope Era clothing store, which is located on the first floor of the building. Despite the damage to his business, he said he’s glad that no one was seriously injured. “Whatever is in there can be replaced. If it’s some floor paneling, I’m not worried about that,” Mistah F.A.B said. “I’m just happy there are no deaths …” Oakland Mayor Barbara Lee confirmed to NBC Bay Area that the dozens of people who were evacuated will be housed. Oakland Fire Department said traffic is blocked along Broadway between 17th and 20th streets. Approximately 50 firefighters battled the blaze. The Red Cross was on the scene. The cause of the fire is currently unknown. ...read more read less
