Workers should not work in an unprotected trench that is 5 feet deep or more. The type of protection installed may be sloping or benching, trench box or shield and steadying.
How deep can trenches be without protection?Protective systems for trench safety include sloping, shoring, shielding, and benching. They are used when soil conditions and the depth of the trench present a hazard to workers.
Although only required for excavations deeper than five feet, it's a best practice to provide some form of stabilization in all trenches.
Trenches 5 feet (1.5 meters) deep or greater require a protective system unless the excavation is made entirely in stable rock. If less than 5 feet deep, a competent person may determine that a protective system is not required.
