Abstract: At approximately 1:20 a.m. on March 20, 2013, Employee #1, a carpenter, was going to evaluate a scaffold that would be unassembled. A crew had removed a piece of plywood over a skylight. The opened skylight did not have temporary railings, toe boards or covering. Employee #1 entered the area, carrying plywood in front of him that obscured his vision. He placed the plywood down and walked onto the open skylight. Employee #1 fell through the unguarded skylight and struck the floor, sustaining a fractured spine and heel. Emergency medical personnel were summoned. Employee #1 was transported to a medical center, where he was treated and then hospitalized.
