Welding equipment set fire to a vintage car at a Riverside auto repair shop causing $150,000 damage, city fire officials say, though a sprinkler contained the flames until firefighters arrived. The blaze was reported at 6:05 p.m. Friday, Oct. 7, inside a 1952 Chevy that was being restored at DMCG Inc., 1860 Chicago Ave., in Freeway Industrial Park. “A guy was welding and ignited the upholstery of the rear seat,” said Acting Capt. Brandon Mollicone. Smoke and water damage also affected several adjoining businesses, Battalion Chief Bruce Vanderhorst said in a written statement. Fire crews finished extinguishing the flames, then used exhaust fans to clear smoke out of the building, and squeegees to remove the water. No one was hurt.
