For trenches five feet deep or more, what safety measure is required?

Explanation:
Deep trenches pose a serious cave-in risk, so when a trench is five feet deep or more, you must install a protective system to keep the walls from collapsing. This protective system—shoring, sloping, or benching—directly controls soil pressure and creates a stable, safe space for workers. The system must be designed for the specific soil type and depth, installed before entry, and routinely inspected by a competent person, with checks after changes in conditions like weather. In short, the required safety measure is a protective system to prevent cave-ins.
