Abstract: On February 13, 2003, Employee #1 and two coworkers were installing a 35 ft long by 5 in. diameter section of flexible stainless steel chimney liner, which was to be tied to a connector pipe attached to an existing heating unit. One coworker was on the roof, feeding in the liner; Employee #1 and the other coworker were in the basement, guiding it in. After inserting approximately 25 ft of the liner, the remaining 10 ft section contacted an energized 7-kilovolt AC overhead power line that was located between 3 and 4 ft from the chimmney. The coworker on the roof received an electric shock and was thrown from the liner; he suffered minor electrical burns to both of his hands and knees. Employee #1, who was guiding the liner, was electrocuted and was pronounced dead at the scene. The other coworker was not injured.
