Abstract: On October 2, 2007, Employee #1 and two of his coworkers were using a metal scraper to remove linoleum tile from the storeroom floor of his employer's establishment, where food products were prepared for caterers, in Mira Loma, CA. A customer, who came in to purchase food product, suggested that they use paint thinner to help remove the tile and then gave the employees paint thinner. Employee #1 and his two coworkers had been scrapping the floor wetted by the paint thinner for about 20 minutes when a flash fire occurred at approximately 6:06 p.m. on October 2, 2007. Employee #1, who sustained serious burn injuries to multiple parts of his body, could not recall how the fire occurred. When the flash fire occurred, Employee #1 ran out of the storage room, grabbed the fire extinguisher, and gave it to one of his coworkers, who sprayed the storage room. Employee #1 was hospitalized for burns.
