Abstract: Two subcontractors were working on a multiemployer worksite--a town water main project. One subcontractor was hired to do blasting; the other was hired to do the trenching. One of the two employees of the blasting subcontractor was setting up a drilling rig to dig holes for dynamite. While he was operating the drilling rig, the top of the boom contacted a 13.8-kilovolt overhead power line. The other employee, who was standing a distance away from the rig, rushed over to shut it down. He received a fatal electric shock when he touched the rig. (This employee was the company owner's nephew.) The rig operator also received a severe electric shock. (He was not listed on an injury line on the original form.)
