Abstract: At approximately 11:30 a.m. on November 10, 2002, Employee #1, a 59-year-old, was attempting to close a 700-pound iron sliding gate by hand. For some reason, the gate rolled past its stopper and came off the track. As a result, the gate fell on Employee #1, pinning him under the gate. Emergency services were contacted and Employee #1 was transported to the Arrowhead Regional Medical Center in Colton, California. He was hospitalized and treated for his injuries, which included: a chest injury, several broken ribs, and a broken collar bone. Five days later he was transferred to the Kindred Rehabilitation Hospital in Westminster, California, where he remained for fifteen days.
