What clearance must be maintained from the furthest projection of moving equipment when using shelter holes for storage?

The clearance that must be maintained from the furthest projection of moving equipment when using shelter holes for storage is 40 inches. This requirement is important for safety reasons, as it ensures that personnel and equipment are kept at a safe distance from potential hazards associated with moving equipment. Maintaining a clearance of 40 inches helps prevent accidents and injuries that could occur if workers or stored materials come into contact with equipment that is in operation or moving. This distance is based on best practices in mine safety and regulations designed to protect workers in potentially hazardous environments.
