What is the definition of a trench?

A trench is defined as a narrow underground excavation that is deeper than it is wide. This definition distinguishes trenches from other types of excavations by emphasizing their depth in relation to their width. According to OSHA standards, a trench typically has a width of 15 feet or less and a depth that makes it significantly deeper than wide, which is critical for safety considerations in construction. Understanding this definition is essential for identifying potential hazards associated with trenching, such as cave-ins, and for implementing appropriate safety measures such as shoring or sloping to protect workers. Such knowledge is vital in the construction industry where trench work is common and can be hazardous if not properly managed.
