Lucerne Valley, CA, May 11, 2012, 8:00am - On Wednesday, May 9, at about 11:30am San Bernardino County Fire received numerous calls stating the Lucerne Valley Market was on fire and explosions could be heard coming from the back of the building. Six fire engines and two truck companies responded from San Bernardino County Fire, along with three engines from assisting agencies. When firefighters arrived on scene five minutes later, a partially enclosed attached work area and large metal rafters filled with content were fully engulfed in flames. Firefighters quickly contained the fire and it was completely extinguished within 90 minutes. The explosions initially reported were caused when the fire reached an electrical transformer. Store employees safely evacuated everyone from inside the store, and occupants of a small strip mall next to the market were also evacuated. The fire is believed to have started in the outside work area. The cause of the fire remains under investigation by San Bernardino County Fire Investigators. Preliminary content and structure damage is estimated at $300,000. The store was closed because of the fire and was able to reopen on Thursday, May 10 at 3:00pm.
