The employee was pulling plywood from the middle of the roof while walking backward. He fell into an opening measuring 4 ft by 4 ft that was intended for a skylight. He fell approximately 20 ft to the concrete floor. The employee was transported to Holy Cross Hospital in Mission Hills, and was hospitalized for eight days. He fractured his check bones, wrist and hip, and dislocated his left arm. The employer did not provide fall protection.
