Abstract: At approximately 11:40 a.m. on May 8, 2008, Employee #1, a field service technician, began arc welding on a tank containing diesel fuel following accepted procedures. Some fuel splashed onto his coveralls, and the flammable vapors ignited as he struck an arc. No fire extinguisher was nearby. He rolled on the ground but the flames on his shoulder reignited his arms and chest. A coworker helped put the flames out by pushing him up against the service truck under a jug of water and trickling water onto him. Employee #1 was hospitalized and treated for second and third degree burns to his arm, shoulder, neck, and face.
