Forklifts, also known as powered industrial trucks, are specialized vehicles that carry, push, pull, lift, load, unload, stack, or tier material of varied sizes, shapes, and weights. OSHA estimates that about a million forklifts are used by about 1.5 million employees and that forklift accidents account for 100 deaths and 95,000 injuries each year. There are extensive regulations for forklift operations and training in the Powered Industrial Truck standard at 29 CFR 1910.178.
