Ashley Hildebrandt, spokesperson for the department, said firefighters were called to the building in the 3800 block of S George Mason Drive, in the area of Bailey’s Crossroads, around 4:11 p.m. Tuesday. Smoke was reportedly coming from the structure, which is a commercial building that houses approximately eight businesses, according to Hildebrandt. Once firefighters arrived, Hildebrandt said they quickly determined the fire was “utility related.” As shown in the video, one of the firefighters opens an exterior door to the building and an explosion occurs, sending a ball of flame outside that completely envelops the firefighter. “He’s totally fine. For him, it was just another day on the job,” Hildebrandt said. “His PPE and his SCBA (self-contained breathing apparatus) did exactly what they were supposed to do and protected him.” Investigators with Fairfax County Fire and Rescue are still looking into what caused the initial fire and the explosion. Hildebrandt said the department will release more information once it’s available. Below is a map of where the explosion occurred:
