When requesting a clearance, an employee needs to provide limits of which of the following?

When requesting a clearance, providing clearance limits is crucial because it defines the specific geographical boundaries within which the work will occur. This ensures the safety of workers and trains in the area by establishing a clear demarcation for activities that might interrupt regular operations. The clearance limits are intended to communicate the scope of the work environment and help maintain safety protocols that protect personnel and equipment.

Operating hours, budget restrictions, and material availability are important considerations in railway operations, but they do not directly pertain to the specific area where work will take place. Therefore, they do not fulfill the requirement to outline the limits required for a clearance request, making the specification of clearance limits the essential information needed in this context.
