Request for Assistance: Preventing Electrocutions by Undetected Feedback Electrical Energy Present in Power Lines

NIOSH requests assistance to prevent the electrocution of workers by undetected feedback electrical energy in power lines. Electrocutions are the third leading cause of occupational deaths in the United States. In 1984, electrocutions accounted for 9.5% (618 of 6491) of all reported occupational deaths. This Alert describes two recent cases of workers who died as a result of feedback electrical energy, which is one cause of occupational electrocutions. Additional case reports are referenced whose circumstances are almost identical to those described. Evaluation of these cases identified three major areas of concern to prevent future incidents: (1) training in proper electrical procedures, (2) verification that power lines are deenergized before work is performed on them, and (3) detection of feedback electrical energy. Editors of appropriate trade journals, safety and health officials, and especially those who work on or in the vicinity of power lines are requested to bring these recommendations to the attention of the general public, managers of electrical utilities, and workers.
