A case study of a warehouse worker electrocuted by a 440 Volt (V) trolley wire was examined. Three shipping and receiving personnel were assigned the task of retrieving a mining auger off the top pallet of a storage rack for shipping to a customer. The storage rack was located along the interior wall of the building beneath the overhead bridge crane track and runway conductors. The 440V conductors were within a few inches of the top of the rack. On the day of the accident, the forklift was out of propane fuel which necessitated the use of the crane to remove the part from the rack. Shortly after the crane operator warned the victim to be careful and before the supervisor had time to deenergize the lines, the victim contacted the energized line. After deenergization occurred, the victim fell from the top of the metal rack to the concrete floor. The contributing factors causing the electrocution included proximity of the metal pallet rack to bare 440V, deviation from the usual procedure of using a forklift to move items from the storage rack, and insufficient hazard recognition by the victim. The authors recommend that pallet storage racks should be removed from the areas of the runway conductors, danger signs should be placed in the vicinity of exposed conductors, danger voltage signs should be placed in vicinity of exposed conductors, guarding should be installed in areas where close worker access to bare runway conductors is necessary, and a company should improve its safety training on hazard recognition and safe work practices.
