Who must inspect a dump or stockpile on the surface of a mine that has been inactive for more than 4 hours?

• A. The open pit shift boss
• B. A designated safety officer
• C. A qualified team of engineers
• D. Any site worker

Answer: (A)

The correct answer is that the open pit shift boss is responsible for inspecting a dump or stockpile on the surface of a mine that has been inactive for more than 4 hours. This requirement is grounded in safety regulations and operational protocols designed to ensure that potentially hazardous conditions are monitored and addressed promptly.

The open pit shift boss has the authority and training to recognize and respond to safety issues that may arise in the mine environment. This role typically involves overseeing workers, ensuring compliance with safety regulations, and managing the overall safety of the area, including any dumps or stockpiles. By conducting inspections, the shift boss helps to prevent accidents related to unstable ground conditions or other hazards that could develop during periods of inactivity.

The other choices do not fulfill the specific responsibility assigned to the shift boss in this context. A designated safety officer may have a role in broader safety oversight, but the immediate inspection duty falls under the jurisdiction of the shift boss. A qualified team of engineers and any site worker lack the direct oversight and operational responsibilities specific to the shift boss role in this situation.
