Shoring & Trenching

All excavations or trenches 4 feet or greater in depth shall be appropriately benched, shored, or sloped according to the procedures and requirements set forth in OSHA's Excavation standard, 29 CFR 1926.650, .651, and .652.

Excavations or trenches 20 feet deep or greater must have a protective system designed by a registered professional engineer.

For regulations regarding proper shoring and trenching, see the EHS Shoring & Trenching Manual.

A Cease & Desist Order will be issued by the AHJ against any job being performed in an improperly-shored trench.
