If loose material is observed on high wall, what should be done?

• A. It must be stripped from a safe distance
• B. Do nothing
• C. Burn off
• D. Spray water

Answer: (A)

Loose material on a high wall is a serious rockfall hazard. The safest action is to strip away that loose material from a safe distance using appropriate equipment. Removing it from a distance reduces the chance of a sudden fall injuring workers or damaging equipment and helps keep the slope stable. Spraying water might help with dust but does not address the actual hazard of loose rock. Do nothing leaves the danger present, and burning off could ignite material or destabilize the face. So, actively removing the loose material from a safe distance is the correct approach.
