VIDEO: San Bernardino County Fire Department crews battled a fire at an abandoned school Wednesday night. According to the fire department, the blaze was reported shortly after 10 p.m. at the structure in the 1500 block of West 7th Street in San Bernardino. When crews arrived, heavy smoke and fire was already showing from the single-story structure. Fire crews were quickly forced to assume a defensive position after the flames caused a partial roof collapse and heavy winds in the area contributed to the fire’s spread. Crews closed off access to West 7th Street in the area of the fire as 46 firefighters worked to contain the blaze. One firefighter suffered a minor injury and was treated on scene.
