The fire was reported at 3:15 p.m. Sunday at 3450 Pacheco Blvd., across the street from the Shell Martinez refinery. County Fire Marshal Chris Bachman said late Sunday afternoon it wasn’t known how the fire started.

Firefighters had the blaze out quickly enough so that it didn’t spread to nearby automotive-business buildings, Bachman added.

There were no injuries.
