Abstract: At approximately 2 p.m. on October 24, 2008, Employees #1 and #2 were at a dump site at the west end of the Los Angeles Airport runways. They were cleaning excess asphalt from the hopper of a patch truck they had used that morning. Employee #1 began by spraying diesel fuel on the hopper of the truck to loosen the asphalt off the hopper while Employee #2 was scraping the asphalt with a tool from the top. They both then proceeded to the ground near the rear of the truck. While Employee #1 was spraying the back end of the truck, a flash fire occurred, burning the hands and faces of both employees. Employee #1 was hospitalized for treatment.
