What is the definition of a trench?

The definition of a trench is an excavation that is deeper than it is wide. This characteristic is crucial for distinguishing trenches from other types of excavations, which can be broader without presenting the same safety hazards. The depth-to-width ratio is important in construction and safety contexts because it affects the stability of the sides of the excavation and consequently the risk of collapse. Understanding this definition helps in implementing the necessary safety measures, such as shoring, to protect workers who may be at risk of being buried or injured in the event of a trench collapse.

In contrast, the options that suggest differing measurements, such as a specific width or depth, do not accurately capture the defining characteristic of a trench and overlook the critical aspect of its geometry relevant to safety regulations and practices.
