Abstract: At approximately 11:50 a.m. on March 30, 2102, Employee # 1 was working with a work crew installing a wooden electrical power pole (#1567252E). Some equipment used in the task were a backhoe used to dig the hole and a boom truck crane consisting of a hoist line to lift the power pole and a claw at the tip to steady the pole while being placed it inside the excavation. While back filling the excavation with the electric pole set in place, a Southern California Edison employee, Worker #2, climbed the electric pole to release a choked sling around the pole. While doing so, a thirteen pound shackle used as part of the rigging in lifting the electrical pole was accidentally dropped approximately 20 feet and hit Employee #1 on top of his head. He spent five nights at LAC/USC Medical Center because of a fractured vertebra.
