During excavation, how far from the trench edge should excavated spoils be deposited?

• A. 1 ft
• B. 2 ft
• C. 3 ft
• D. 4 ft

Answer: (B)

Keeping excavated spoils at a safe distance from the trench edge is a key safety measure to prevent the trench from being undermined and to protect workers from falling debris. If spoil piles sit too close, their weight and any movement can push on the trench wall or cause material to slide back into the trench, increasing the risk of a cave-in or injury. Providing a buffer—typically at least two feet—creates space for safe work, reduces the chance of material spilling into the trench, and gives room for workers to move and for equipment to operate without encroaching on the edge. Two feet is the common minimum distance used in excavation safety; in unstable soils or under heavy vibration, more distance may be required, but two feet is the standard baseline.
