Apprentice lineman electrocuted while upgrading a power distribution system, March 6, 1989.

NIOSH 1989 Jul; :1-5
A 21 year old male apprentice lineman was electrocuted when he contacted a 13,700 volt power line while upgrading a power distribution system. The victim was employed by a small power line construction company with 18 employees that has been in operation for 11 years. The company has a set of written safety rules that all employees are required to read and sign to verify that they understand them. The victim was working as part of a four person crew upgrading a single phase power distribution system to a three phase system. At the time of the incident the crew was working on the second line, which had been pulled off a reel to the pole where it was to be dead ended. After the line had been properly sagged, the victim in the bucket of an insulated bucket truck began to secure the line in a dead end clamp. A 14 foot long tail extended beyond the clamp, probably because this was what had been left on the reel. The groundman heard a zip and then heard a part of the clamp hit the ground. On removing the victim from the bucket he was wearing only light leather gloves. His insulated rubber gloves and leather overgloves were on the floor of the bucket. It was thought that he may have pushed a cable off of the bucket with his right hand while holding the clamp in his left hand, thus completing a circuit to ground. The victim apparently removed his protective equipment to install small nuts on the clamping device. It was recommended that these clamps be redesigned so that workers would be able to install them while wearing protective gloves.
