Abstract: Employee #1, a grip for Werts Films, was working from the rafters in the lighting grid approximately 35 ft above the stage. Employee #2 was working from a scissor lift, below Employee #1. Employee #1 climbed over the catwalk guardrail to prepare the lines/lamps that were to be rigged above the stage floor. As employee #1 stepped onto the grid, he also stepped on a loose 2 in. by 4 in. piece of debris, causing him to lose his balance and fall through the grid. He fell onto the scissor-lift platform directly below (approximately 10 to 15 ft) and crashed into Employee #2. Employee #1 was not wearing any ppe. The employees were lowered to the ground and removed to a local hospital for treatment. Employee #1 was hospitalized; Employee #2 was treated and released.
