If a roof hazard is detected, what is the appropriate action?

• A. Continue work with caution.
• B. Ignore until a formal inspection.
• C. Stop work, evacuate if necessary, apply rock support or retreat per plan, notify supervisor.
• D. Move workers to a different area without addressing hazard.

Answer: (C)

The action is about immediate hazard control and clear communication when a roof hazard is detected. Stop work right away, evacuate if necessary according to site procedures, apply rock support or retreat per the plan, and notify the supervisor. This sequence quickly isolates the danger, secures the area, and gets a qualified review to implement the planned controls, which is essential for preventing a roof-related incident.

Continuing with caution still leaves workers exposed to a sudden roof collapse or rock fall. Waiting for a formal inspection delays risk mitigation, and moving workers elsewhere without addressing the hazard doesn’t reduce the danger.
