Crews extinguished a large fire that gutted a commercial building in Chatsworth Wednesday night.
The flames were reported around 9:50 p.m. at a one-story building at 20150 Sunburst St., the Los Angeles Fire Department said in an alert.
The structure houses Arizona Pipeline Co., fire officials said. The pipeline contractor is based in Hesperia but lists the Sunburst Street address as its Chatsworth division.
Shortly after 10 p.m., firefighters transitioned into defensive mode, fighting the blaze from outside the building as flames engulfed the building and a heavy column of smoke poured through the roof.
Aerial video from Sky5 showed sparks among the flames inside the building.
One firefighter suffered a burn injury and was taken to the hospital but was expected to survive, according to LAFD.
By about 11:30 p.m., the fire was put out by 120 firefighters at the scene, LAFD said in an update.
