It is believed the fire began on the fourth floor of the building on the 900 block of North 63rd Street around 2:15 a.m. Monday. Officials evacuated adjacent buildings due to the possibility of ongoing collapse; flames already caused the roof to cave in. Two firefighters, among the approximate 180 called to the scene, suffered minor burns and were being treated on site. There have been no reported injuries to any of the more than 50 residents displaced by the fire, however, officials say they have not yet been able to confirm that everyone has made it out safely. As firefighters worked for hours pouring water onto the multi-alarm fire, the roads surrounding the scene have become an icy mess. With fire trucks, emergency vehicles, and hoses scattered across the street, and now iced-over roads, firefighters are having to maneuver around multiple obstacles while tackling the fierce flames. Along with the fire personnel, including Philadelphia Fire Commissioner Adam Thiel, numerous agencies have responded to the scene. The American Red Cross is assisting those displaced and the Red Paw Relief is assisting the pets affected by the fire. The Office of Emergency Management is keeping residents aware of the conditions - including road closures and detours. SEPTA Route 10 is being detoured and traffic is being blocked on 63rd Street. The Streets Department is salting the icy roads. Beyond the possibility of fire damage, neighbors on the block are also dealing with a power outage. There is no word on when the power will be restored. A warming center has been opened for displaced residents at Commodore John Barry Elementary School located at 5900 Race Street.
