Lineman electrocuted after contacting energized conductor while working from the bucket of an aerial lift truck - Virginia.
Morgantown, WV: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, FACE 92-02, 1992 Jan; :1-5
A 35-year-old male lineman was electrocuted after he contacted an energized powerline while working from the bucket of an aerial lift truck. The victim was part of a five-man crew assigned to transfer a three-phase, 34,500-volt, overhead powerline system from one utility pole to a taller utility pole. The transfer of the powerlines had been completed, and insulating blankets and line sleeves still covered the powerlines, insulators, and crossarms. While removing the line sleeve from the middle powerline, the victim's rubber glove became caught on an aluminum wire securing the powerline to the insulator. When the victim pulled his arm back, the rubber glove was partially pulled off, and the victim's exposed right wrist contacted the powerline. Electrical current passed through the victim's right arm and exited the body at the left side of the lower abdomen, which had been in contact with the utility pole crossarm, causing his electrocution. NIOSH investigators concluded that, in order to prevent future similar occurrences, employers should; 1) stress the importance of adherence to established safe work procedures; 2) review and revise, where applicable, safe work procedures regarding the removal of insulating materials, the positioning of aerial buckets, and the procedure used in securing powerlines to insulators.
