Prior to removing blocking devices on a signal leading to an OOS track, what is the first action a dispatcher must take?

The first action a dispatcher must take before removing blocking devices on a signal leading to an Out of Service (OOS) track is to conduct a job briefing with the Rail Worker In Charge (RWIC). This step is crucial because it ensures that all individuals involved, particularly those who will be working in or near the OOS area, are fully aware of the current situation and agreed upon procedures.

The job briefing helps to confirm that everyone understands their roles, the risks involved, and that safety protocols are being followed before any actions that could lead to train movements or exposure to hazards are taken. Engaging in such communication promotes teamwork and ensures that safety is the priority, particularly in complex situations where multiple parties might be involved.

Taking this proactive measure minimizes the risk of accidents or miscommunication, thereby securing the safety of both the workers and the train operations.
