Los Angeles firefighters doused a dumpster fire on Saturday morning that broke out behind a Kohl’s store in Northridge. The blaze began at 8:18 a.m. at a combination compactor-dumpster that spanned the outside and inside of the Kohl’s store at 8800 Corbin Ave., said Brian Humphrey, a spokesman for the Los Angeles Fire Department. It took 34 firefighters 21 minutes to snuff it out. A fire sprinkler system helped lesson the damage to store equipment and its loading dock, Humphrey said. There were no injuries. The cause of the fire and damages were under investigation.
