What is the minimum distance from the edge of the spoils to the edge of the trench?

• A. 6 feet
• B. 2 feet
• C. 18 inches
• D. 10 feet

Answer: (B)

Two feet. In trench safety, spoil piles need a buffer from the trench edge so the trench wall isn’t destabilized by the weight or movement of the excavated material, and so workers have room to move and access ladders or shoring. Two feet provides the minimum safe distance; more (like six or ten feet) isn’t necessary as a requirement, and less (eighteen inches) isn’t enough to prevent a potential cave-in or interference with safe operations.
