A massive fire late Tuesday ripped through an empty five-story hotel and apartment complex in northwest Oklahoma City that was under construction, fire officials said. There were no injuries reported in the blaze at the construction site, which prompted a “five-alarm response” with more than 80 firefighters on the scene, said Oklahoma City Fire Department Battalion Chief Benny Fulkerson. “There was fire on the roof when we got here,” Fulkerson said. “The roofing material involved was kind of a rubbery material that does not go out easily with water once it’s on fire. It was just melting and pooling and continued to burn and it just spread very quickly across the rooftop of this large building.” The fire burned for more than four hours, and Fulkerson said there was extensive water and smoke damage throughout the structure.
