Abstract: At approximately 2:00 p.m., on February 4, 2002, Employee #1, a temporary maintenance helper for a low income housing authority for the city of Los Angeles, and two coworkers, were manually picking up trash in a 20,000 square foot storage yard and transferring the trash to a large industrial trash bin. The site consisted of three 10,000 square foot buildings, materials receiving, fleet maintenance and construction. All three buildings were separate entities within the housing authority. Employee #1 left his assigned work area, went to the fleet maintenance building and took a 5000-capacity Toyota forklift, Serial Number 79742. He drove back to his assigned work area on the forklift. He lost control and hit a 1999 GMC C7500 flat bed truck. Employee #1 sustained a compound fracture of the left arm above the elbow. He was treated at the scene by the Los Angeles Fire Department Paramedics and transferred to Kaiser Permanente hospital. Employee #1 was hospitalized for several days and had surgery to the left arm. Employee #1 was not trained in the operation of the forklift. The causal factors of the accident were lack of security, giving access to the forklift keys, and lack of training.
