For a trench to require shoring, it must be deeper than how many feet?

• A. 5 ft (1.5 m)
• B. 6 ft (1.8 m)
• C. 8 ft (2.4 m)
• D. 10 ft (3.1 m)

Answer: (A)

A trench typically requires shoring when it exceeds a depth of 5 feet. This guideline is established to ensure the safety of workers and to prevent potential collapses, which can be particularly hazardous in deeper excavations. The presence of soil materials and groundwater conditions can exacerbate the risk of trench failure, so regulations emphasize shoring as a critical safety measure once this depth is surpassed. Therefore, when trenches are deeper than 5 feet, appropriate shoring techniques must be employed to protect workers from cave-ins or other related hazards.
