Abstract: Employees #1 and #4 were clearing a jam of corn oil bottles from an ARPAC Corporation shrink wrap oven, model 105-28TW. In removing the carton of bottles, oil was spilled onto the conveyor belt that moves through the oven. Employee #1 began washing the conveyor belt with a soap solution at the exit end of the oven. Employee #4 used ethyl alcohol to remove the oil residue from the belt at the oven's entrance. Employee #4 poured some alcohol onto the belt, which then moved through the 400 to 500 degree oven. An explosion and fire ensued. Employee #1 received 2nd-degree burns over 20 percent of his head and upper body. Employees #2, #3, and #4 were treated for smoke inhalation.
