When loose material or trees are observed on exposed wall area, what should be done?

• A. A safe means of scaling the wall shall be provided and loose material removed before any further work is performed in the area.
• B. Place warning signs only
• C. Evacuate the area and stop work completely
• D. Do nothing

Answer: (A)

Hazard recognition and immediate control of loose material on an exposed wall is the key idea. When you see loose rock or trees, the risk is rockfalls or a wall collapse that can injure workers. The safest course is to provide a safe method for scaling the wall and remove the loose material before any further work continues. This directly addresses the danger by stabilizing the area so it’s safe to proceed. Merely putting up warning signs doesn’t remove the hazard, and stopping work entirely isn’t required if the hazard can be controlled by removal and stabilization. Doing nothing would leave workers at risk.
