Under an ERP, who would the mine coordinate with during an emergency?

• A. Internal supervisors only.
• B. The miners' union only.
• C. The control room operator only.
• D. Emergency services through liaison.

Answer: (D)

In an ERP, the mine coordinates with emergency services through a designated liaison. This person acts as the single point of contact to relay on-site conditions, hazards, casualty status, and resource needs to external responders such as police, fire, ambulance, and mine rescue teams, and to coordinate their arrival and handover to on-site incident command. The liaison keeps actions synchronized so external and internal responders don’t duplicate efforts or issue conflicting instructions. On-site supervisors, the control room, or unions may be involved in the response, but the official channel for external emergency coordination is through the liaison to emergency services.
