Trenching and Excavation Safety

A trench is defined as a narrow excavation (in relation to its length) made below the surface of the ground. In general, the depth of a trench is greater than its width, but the width of a trench (measured at the bottom) is not greater than 15 feet (4.6 m). What are the dangers of trenching and excavation

Engineering controls—for example benching, battering or shoring the sides of the excavation to reduce the risk of the ground collapsing. If risk remains you must minimise it by implementing administrative controls, so far as is reasonably practicable. For example, install warning signs near the excavation site.

Excavation Methods Encyclopedia

Before any excavation is begun, the site must be located. Techniques used to find a site may include remote sensing (for example, by aerial photography), soil surveys, and walk-through or surface surveys. The digging of shovel tests, augured core samples and, less commonly, trenches may also be used to locate archaeological sites.
