Accident: 201360559 - Electric Shock - Contact With Overhead Line Thru Boom
A ground worker on a power line crew was retrieving a piece of copper wire from the back of a digger-derrick truck. (He had earlier warned a coworker to stay clear of the truck.) The hydraulic hose on the boom on the digger-derrick contacted an 8000-volt overhead power line, and the ground worker received an electric shock. Coworkers administered cardiopulmonary resuscitation until emergency medical services arrived. Initial tests indicated that the injured employee had some brain activity, and no liver or kidney damage. Further testing later that day indicated that the employee had no brain activity, and he was pronounced dead.

Accident: 202288270 - Fell From Truck And Struck Head On Pole
A four-person power line crew was replacing one pole of a two-pole spar-arm electric transmission structure. The crew was using a Telelect Commander II digger-derrick truck to remove the old utility pole. The pole had been disconnected from the structure and had been cut off in sections, with the butt end still in the ground. One of the employees was at the boom control station, which was located to the side of the lower portion of the boom. The load line was wrapped around the pole. When the employee put tension on the load line, the turret mounting bolts for the boom sheared, causing the boom to separate from the truck. The operator tried to jump clear, but his foot apparently caught on a portion of the boom. He fell head first to the ground, and his hard hat fell off during the fall. His head struck the new pole, which was lying on the ground. He died of severe head injuries.

Accident: 200260305 - Electric Shock - Contact With Overhead Line Thru Load Line
A power line crew was installing an overhead power line in a rural area. One of the power line workers was using a winch attached to a digger-derrick positioned under the line to pull the last phase conductor of the line up to the crossarm of a utility pole. The end of the conductor somehow twisted, causing it to point in a vertical position. The conductor went beneath the insulating blanket covering a conductor on a nearby energized line and contacted the energized line. This energized the digger-derrick, electrocuting an employee leaning against it.
