At which type of incident should an accountability system be established?

• A. All incidents
• B. Large incidents
• C. High-risk incidents
• D. Routine incidents

Answer: (A)

A personnel accountability system is essential at every incident. It ensures the Incident Commander can track who is on scene, where each person is operating, and their safety status, so a rapid rescue or safety action can be taken if needed. Standards require accountability from the moment responders arrive and to maintain it throughout operations, regardless of incident size or risk level, because conditions can change quickly. Even routine or small incidents benefit from a simple check-in/check-out process to keep the roster accurate and prevent gaps in safety. Therefore, establish accountability at all incidents from the outset and maintain it as operations unfold.
