Fatality #12

On August 6, 2008, a 38 year-old shift foreman with 15 years experience was fatally injured on the surface of an underground potash mine. It was the 12th metal/nonmetal fatality this year. The victim was electrocuted when he contacted an energized steel water line. One conductor of a 480-volt electrical circuit short-circuited to an abandoned heater tape where both circuits passed through a common condulet box. The heater tape, which was attached to the water line, overheated and energized the water line to 277 volts. Your comment?
