Self-Storage Facility, Storage / Warehouse Contra Costa, CA – Sprinklers assist firefighters in containing vehicle fire in storage unit July 28, 2015 viking210 A vehicle caught on fire in a storage unit, causing about $35,000 in damages, a Contra Costa County fire official said. Nobody was injured in the blaze in an unincorporated area near the city of Martinez, said Fire Marshal Robert Marshall. Nearly 20 firefighters responded at 10:18 p.m. Thursday to reports of a fire in a storage facility in the 5700 block of Pacheco Boulevard, near Interstate 680 and Highway 4, Marshall said. Crews arrived and found smoke billowing from one of the units, where a fire sprinkler was spraying water, he said. Firefighters used four engines and a truck to prevent the flames from spreading to other units, Marshall said. They got the one-alarm fire under control within 10 minutes. The cause is under investigation but Marshall said it might have started from oily rags left inside the vehicle. “You need to dispose of rags like that because they can spontaneously combust,” he said. “We don’t know if that’s what happened, but all of the right ingredients were there.”
