Abstract: Employee #1 was working on a scissor lift under a 16 ft 3 in. ceiling. He and a coworker on another scissor lift were removing insulated ceiling panels approximately 3 ft wide and 15 ft to 18 ft long and attached to the ceiling by 3/8 in. threaded rod. Employee #1 did not secure himself properly to the 3/8 in. threaded rod. He looped his lanyard around the rod and then clipped the hook on the lanyard itself. His coworker let the other scissor lift down. Employee #1 continued to push and pull on the panel and it broke loose, falling 16 ft 3 in. to the ground and pulling him to the floor, causing injury. The lanyard had slipped past the end bracket of the threaded rod.
