For which trench depth does federal OSHA require a protective system to be used?

Federal OSHA regulations state that a protective system is required for trenches that are greater than 5 feet in depth. This requirement is crucial because as trench depth increases, so does the risk of cave-ins. Trench-related hazards can be significant, leading to serious injuries or fatalities if proper precautions are not taken.

To safeguard workers, protective systems such as trench boxes, shoring, or sloping are mandated for these deeper excavations. The standards aim to ensure that employers take the necessary steps to create a safe working environment, thereby minimizing the likelihood of accidents associated with trench work. Consequently, the requirement for a protective system above this depth emphasizes the necessity for additional safety measures where risks are elevated.
