Abstract: At approximately 11:46 a.m. on October 16, 2008, Employee #1, a construction laborer-leadman, worked for a residential and commercial construction company. His supervisor provided lacquer thinner and cloth rags to him and his coworkers, instructing them to clean paint and adhesive from the floor of a janitor's closet. They were not trained on the safe use and hazards of working with lacquer thinner or flammable liquids. They were working in the room on their hands and knees applying the lacquer thinner to the floor using cloth rags. A coworker, closest to the door and the water heater, yelled fire and ran out of the room. Employee #1 stood up and turned around, observed that the room was on fire, and ran for the door. He fell near the water heater, stood up, and ran out of the room with his clothes on fire. His coworkers extinguished the fire on his clothes and skin. The ceiling sprinkler system eventually put the fire in the room out. Employee #1 was hospitalized with second and third degree burns to his right arm, legs, and torso.
