Abstract: On July 24, 2010, Employee #1, a chief lighting technician of Big Adventure, was working at a location shoot, which was a circus set placed in a parking lot behind a Best Buy on Los Feliz Boulevard. He walked down steps of the gaffer's trailer, which consisted of 6 risers, and his shoestring caught on the stairs. He twisted his left foot, which caused him to fall to the ground and strike the back of his head. Employee #1 did not report the incident to anyone in management or to the set medic. After leaving work, he went to a friend's house, where he experienced severe headaches. He was transported to Community Hospital of Long Beach and then was transferred to Long Beach Memorial Hospital, where he was hospitalized for treatment of skull and brain injuries. The employer was cited for failing to report the serious accident within eight hours (Regulatory:342(a)) and for not having stair rails on the stairway (General: 3214(a)).
