Abstract: At approximately 3:00 p.m. on November 11, 1999, an employee was injured when he fell into hot tar that was on the roof where he was working. The employee was working on a flat roof that was approximately 25 ft high. They workers had put down hot tar on the roof. There were many openings in the roof and one was about 1.5 square ft opening in the roof. The cover had been taken off so that mopping could be done next to the 8 in. high lip of the opening. One of the mop handles had been put through the opening and was hanging out over the roof a few feet. The employee was moving from one area of the roof to another when he tripped over the mop and fell into the hot tar that was on the roof. He was taken to the hospital where he stayed for 10 days. He received third degree burns on his hands and stomach.
