Abstract: At approximately 5:00 p.m. on August 3, 1994, Employee #1, a spray painter, noticed that air cylinder parts had stopped coming along a conveyor system. As he had been taught to do, Employee #1 picked up a nearby one gallon can of toluene-based lacquer thinner and a brush and reached into the Ransburg spray painting booth to clean off the spraying disk head. This was a common practice done four to five times during a shift to keep residue from building up on the disk. Employee #1 felt an electrical jolt/shock and flame on his bare right hand. Frightened, he tossed the one-third full open can of lacquer thinner aside. The vapors ignited and the flames climbed a nearby wall and ventilation stack and started a fire on the plant roof. Employee #1 suffered first- and second-degree burns to his arms, hands, and left upper chest area.
