Abstract: A fence installer and his helper were installing an additional 1.8-meter-height of cyclone fencing on top of an existing 3.7-meter-high fence. (The owner of the fencing company had not inspected the job area to see if any hazards existed.) When the employees arrived at the site, a supervisor with the plant (a bakery run by a grocery store chain) showed the employees the area that needed the additional fencing. The existing fence enclosed a 16-kilovolt substation. The ladder on the truck was too short, so the supervisor used a forklift with a wooden pallet to lift the two employees (who were not wearing a personal fall arrest equipment) 3.7 meters above the ground to access the top of the fence. The fence installer was connecting the new section to the existing fence with a fence needle. The needle touched a 16-kilovolt bus that was approximately 1.5 meters inside the fence. The employee received an electric shock and first- and second-degree burns on the right side of his face and on his right hand and arm. He was hospitalized for his injuries. The helper was not injured even though electric arcing occurred as a result of the fault.
