What should be requested at the occurrence of tactical benchmarks in the system of accountability?

When tactical benchmarks are achieved during an incident, a Personnel Accountability Report (PAR) is crucial for ensuring the safety and accountability of personnel on the scene. A PAR serves as a systematic way to track the status and location of firefighters and other personnel, especially in environments where visibility and communication may be compromised.

Requesting a PAR allows incident commanders to confirm that all team members are accounted for and safe, particularly after a significant event or operational milestone in the emergency response. This process is vital for identifying whether any personnel may be lost, trapped, or in need of assistance, thereby enhancing overall safety and optimizing resource allocation in the heat of the moment.

While the other options may have their respective roles in the incident management process, they do not directly address the critical need for accountability and safety verification that a PAR provides at benchmarks during operations.
