Loading trucks, trailers, and railroad cars with powered industrial trucks.
(1) Wheel stops or other positive protection must be provided to prevent railroad cars from moving during loading or unloading.
(2) Fixed jacks may be necessary to support a semi-trailer and prevent up-ending during loading or unloading if the trailer is not coupled to a tractor.

(a) Trucks or trailers are secured to the loading dock with a mechanical system that prevents movement away from the dock during loading, unloading, and boarding.
(b) All of the mechanical equipment is installed, maintained, and used as recommended by the manufacturer.
(c) Any damaged mechanical equipment is removed from service immediately and is not used to secure trucks and trailers.
(4) The flooring of trucks, trailers, and railroad cars must be checked for breaks and weakness before use.
