Shoring is required in the context of trenching operations primarily to prevent the collapse of the walls, ensuring the safety of workers who may be working in or near the trench. The specific depth at which shoring becomes necessary is dependent on regulations established by organizations like OSHA (Occupational Safety and Health Administration).

In most scenarios, shoring is mandated when a trench is deeper than 48 inches. This is because trenches that reach this depth significantly increase the risk of cave-ins, which can be fatal. The requirement for shoring at this depth serves to protect workers by providing structural support to the trench walls, thereby minimizing the potential for accidents.

Other options like depths over 36, 60, or 72 inches are either not consistent with the current regulatory guidelines or represent thresholds where additional safety measures may be considered rather than the specific requirement for shoring. Understanding this regulation is key for anyone involved in excavation work, as it highlights the critical importance of safety practices in preventing trench-related incidents.
