Abstract: Employee #1 was employed as a roofer on a commercial construction site. Employee #1 and a coworker, leased employees, were working on a 4:12 pitched roof with their controlling employer. They were organizing materials and rolling out felt in preparation for the application of the roofing material. Fall protection consisted of safety belts with safety lines tied to beams inside open skylights near the peak of the roof. It was rainy and stormy. As Employee #1 was moving the anchor point of his safety line in order to move across the roof, he slipped on the plywood sheeting, fell to his back, and started sliding downward. His new rain gear added to the slide. Since his safety line was not anchored, Employee #1 fell over the eave approximately 28 ft to the ground, fracturing his ankle and injuring his back. Inadequate fall protection led to alleged violations against the controlling employer.
