When operating in a dangerous building, PARs should be conducted at intervals not to exceed how many minutes?

Conducting Personnel Accountability Reports (PARs) at intervals not to exceed 20 minutes is essential for ensuring the safety of all personnel operating in a dangerous building. This practice is critical because it allows incident commanders to assess the location and status of firefighters, helping to ensure that no one is missing or trapped.

The 20-minute interval is a guideline that balances operational needs and safety. It provides sufficient time for firefighters to perform their tasks while also allowing for regular check-ins to maintain accountability in potentially chaotic environments. Such frequent assessments help in making timely decisions regarding resource allocation, potential evacuations, or adjustments to fire suppression tactics based on the evolving conditions within the structure. Keeping this interval in mind enhances situational awareness and reinforces a culture of safety within the firefighting team.

While longer intervals may seem less demanding, they could pose significant risks if an emergency situation arises within the building, as accountability for personnel would lag and jeopardize safety. This is why the 20-minute maximum limit is widely accepted as a best practice in incident command protocols.
