Abstract: At approximately 1:00 p.m. on October 6, 2004, Employee #1 and Employee #2, working on a construction site located at a Ralph's Supermarket in Pasadena CA, were positioned approximately thirteen ft above the ground on the elevated work platform of a scissor lift. They were dismantling ceiling wires and pulling off wood beams at the interior north wall of the site. About twenty minutes into the work process, Employee #1 was attempting to gain height to cut a ceiling wire with bolt cutters by standing on the mid-rail when he slipped and fell to the concrete floor. Employee #1 was transported to Huntington Memorial Hospital and admitted the same day, at 2:18 p.m. He sustained a laceration of the abdominal wall, punctures in his head and hands, and a fracture of his left wrist. After undergoing two operations, he was discharged on October 9, 2004, at 12:35 p.m. Equipment Information and Measurements: A Central City Enterprises employee confirmed that the scissor lift involved with the accident is the number 2 scissor lift, a model year 2000 JLG 2033E3 Model 2033-E3, serial number 0200056781 SL-300-2.
