What should be done if there are unsafe high walls?

If there are unsafe high walls, the most effective action is to correct the situation immediately or barricade off the area. This is vital for safety because high walls in surface mining can present significant hazards, such as rock falls or collapses, that pose risks to workers' safety. Taking immediate corrective action ensures that the risk is eliminated as soon as possible, preventing accidents and maintaining a safe working environment.

Barricading off the area serves as an additional precaution. It acts as a physical barrier to keep workers away from the danger zone until a proper solution can be implemented. This approach aligns with best safety practices by prioritizing the health and safety of all personnel involved.

Monitoring unsafe conditions, reporting to a foreman, or leaving the walls as they are does not adequately address the immediate risk and could lead to serious consequences, making proactive measures essential in managing hazardous situations.
