A trench is specifically classified as a narrow excavation that is deeper than it is wide, where the depth is typically at least 5 feet. This definition aligns with safety regulations, as the potential hazards associated with deeper excavations require specific safety measures to be implemented.

When the depth reaches 5 feet or more, the risk of cave-ins and the stability of the surrounding soil become significant factors that must be addressed to protect workers. Consequently, once an excavation meets or exceeds this depth, it is categorized as a trench, necessitating the use of protective systems such as trench boxes or shoring to ensure the safety of workers.

Understanding this classification is crucial for ensuring adherence to safety regulations and for implementing the right protective measures during excavation work. While shallower excavations may also pose risks, the demarcation at 5 feet is vital for aligning with industry standards regarding trench safety.
