How far should material excavated from trenches be placed away from the edge of the trench?

• A. 2 ft (0.6 m)
• B. 3 ft (0.9 m)
• C. 4 ft (1.2 m)
• D. 5 ft (1.5 m)

Answer: (A)

The recommended distance for placing excavated material away from the edge of a trench is 2 feet (0.6 meters). This guideline is grounded in safety practices designed to prevent cave-ins and falls, as well as to maintain the stability of the trench walls. Keeping the material at a specified distance helps ensure that the weight of the excavated soil does not exert undue pressure on the trench sides, which could lead to collapse. Additionally, by adhering to this distance, workers can move around the site safely without the risk of tripping over the excavated material or having it inadvertently fall back into the trench. This practice also aids in providing a clear work area for further operation and maintenance activities.
