When dealing with unstable spoil piles, which practice helps prevent collapse?

• A. Remove all safety measures and proceed.
• B. Keep a safe distance, assess slope stability, use spotter, and stabilize the pile if required.
• C. Move spoil piles without assessment.
• D. Add more material to the pile to stabilize it.

Answer: (B)

Unstable spoil piles require proactive safety steps to avoid a collapse. The best practice is to stay well clear of the edge, continuously assess the pile’s slope and movement, have a spotter watching for signs of instability, and take stabilization actions if needed. Keeping a safe distance reduces exposure to a potential slide. Assessing slope stability helps identify if the pile is over-steepened or showing movement so you can intervene before a collapse occurs. A spotter provides real-time warnings and helps coordinate safe actions, especially when heavy equipment is nearby. If the pile needs stabilization, apply appropriate measures such as shaping the pile to safer angles, benching, removing unstable material, or other stabilization steps before proceeding. This combination minimizes risk and protects workers. Other options ignore safety, proceed without evaluating the pile, or would add material without addressing stability, all of which can increase the chance of a collapse.
