Lifting devices and other material restrained appropriately (strapped) in the delivery vehicle may acquire potential energy during transport. The action of releasing the restraint may convert any acquired the potential energy to kinetic energy, thereby causing the lifting device to move. Personnel need to be aware of the possibility for movement based on released kinetic energy during the unloading preparation and assume a safe body position.

Communicate with vendors and contractors that best delivery practices would include: 1) chocking the wheels touching the delivery vehicle bed, minimizing the potential for moving after the strapping is released; 2) having a second person to assist with loading and unloading of equipment; 3) always to be aware of their body placement, dont place their body in the pathway of moving equipment for which they have no control; and 4) consider a different transportation vehicle and restraining system.
