Abstract
The case of a worker who was electrocuted when he touched the hoist cable of a crane in contact with an energized overhead power line was reported. The man had worked for 5 years for a construction company which had a formal written safety program and a designated safety officer. The construction crew to which he belonged was building an elevated highway entrance ramp. He was removing forms from a concrete retaining wall, poured several days earlier. The worksite was directly beneath an overhead power line. As he removed the forms they were placed on a choker. When he finished piling the forms on the choker he signaled the crane operator to extend the boom to the area where the materials were lying. The crane operator extended the boom and lowered the hoist cable. Neither the victim nor the crane operator were aware that the crane's boom had contacted the 2400 volt line. Immediately on connecting the choker to the hoist cable, the victim fell to the ground. The crane operator jumped from the crane to help. Five coworkers received mild shocks while attempting to help the victim. Only after the rescue squad arrived did any one realize the crane was in contact with the wire. It is recommended that cranes should not be operated within 10 feet of an energized power line. Employers should either determine that adequate clearances will be maintained, or arrange for power lines to be deenergized and grounded. Adequate training of the workers should have made them aware of the dangers at this scene.
