What must be done if hazardous overhanging walls and other unsafe ground conditions are not corrected promptly?

• A. The areas must be barricaded or posted
• B. The areas must be sealed off with concrete
• C. The areas must be flooded
• D. The areas must be sprayed with warning paint

Answer: (A)

When there are hazardous overhanging walls or other unsafe ground conditions that aren’t corrected right away, the immediate priority is to keep people out of reach of the danger. Barricading or posting the area provides a clear, physical and visible boundary that prevents access until the hazard is resolved. This approach directly reduces the risk of someone entering a unstable zone and getting injured from a collapse or ground failure. The barricade acts as a protective barrier, while posted warnings alert workers to the danger and reinforce the boundary. Other options don’t offer the same level of protection or practicality. Sealing the area with concrete isn’t an immediate, feasible fix for an unstable face or overhang and would not stop access in the meantime. Flooding the area can create additional hazards and doesn’t address the stability issue. Spraying warning paint doesn’t stop people from entering the hazard zone and can wear away or be ignored, leaving the danger unmitigated.
