Where worksite protection is primarily applied by the Network Control Officer, the correct and accurate location of the worksite is critical in ensuring the safety of workers and rail traffic.

Where worksite protection is primarily applied in the field, the importance of the Protection Officer identifying the worksite location to the Network Control Officer is reduced, due to the application of mandated safety measures. The location and application of the safety measures in the field are in this case more important. The Network Control Officer must understand how the application of safety measures affects rail traffic movement.
