A dozen people were injured, three critically, on Tuesday after a reported explosion and fire at a metal-polishing company in northwestern Orange County.
Many of the victims suffered facial and forearm burns in the 9:49 a.m. explosion at Gorilla's Polishing Corp. at 531 E. Commercial Way in La Habra (map), according to Greg Siggins of Cal/OSHA, the state agency investigating the blast.
Fire officials told NBC4 that the blast was likely not caused by any chemicals used at the business, but possibly from a build-up of lint or dust in ducts in the building.
The business was evacuated and nearby roads are closed for the fire investigation.
The initial report was received from occupants of a nearby building.
