Abstract: Employee #1 was loading a trailer with skids of truck parts using a Hyster E50B forklift (serial #B108V11582F). He was approximately 14 ft into the trailer along the left side from the entrance when the trailer bed and side walls separated. The rivets holding the trailer bed and side walls were sheared, causing the bed and walls to separate under the weight of Employee #1 and the forklift. The truck bed collapsed, dropping the employee onto the forklift. Employee #1 suffered lower back bruises and soreness. Employee #1 was trained in forklift operation except for the use of seat belts, which was not required by the employer.
