Which regulation applies to the clearance required for moving supplies?

The regulation specifying that clearance must be no less than 24 inches is foundational for ensuring safe movement and accessibility when transporting supplies. This requirement is designed to prevent accidents and facilitate efficient operations within the mine. Proper clearance helps avoid potential obstructions that could inhibit safety or create hazards for workers navigating the area.

While other options may present different perspectives, they do not prioritize safety protocols or successful operational standards in the mining environment. The 24-inch clearance is particularly critical in narrow passages or areas where equipment and personnel are working closely together. By adhering to this clearance requirement, mines can significantly reduce risks associated with supply delivery and movement, ensuring a safer workplace for everyone involved.
