Firefighting operations are high-risk environments where personnel face immediate and changing hazards. A core principle of managing these emergencies is maintaining continuous situational awareness of every responder operating on the scene. Strict procedures are necessary to ensure that no individual is lost or injured during an incident involving rapidly evolving conditions. The primary mechanism for upholding this safety standard is a systematic roll call process confirming the status and location of all assigned teams.
Defining the Personnel Accountability Report
The Personnel Accountability Report (PAR) is a formal, procedural roll call used to confirm that all assigned personnel are physically present, accounted for, and safe. This report is a specific communication requirement within the Incident Command System, not an informal check. The goal of a PAR is to provide the Incident Commander (IC) with an accurate, real-time snapshot of the number and well-being of all responders operating at an emergency scene. It ensures every individual’s safety status is verified at predetermined intervals or following specific events.
The Importance of Personnel Tracking
Tracking every firefighter is necessary due to the high-hazard environments they operate within. Firefighters often work in atmospheres classified as Immediately Dangerous to Life or Health (IDLH), where conditions like extreme heat, toxic smoke, and oxygen deficiency pose an immediate threat. Limited visibility and rapid environmental changes increase the risk of disorientation, separation from a crew, or becoming trapped. Personnel tracking is driven by the potential for structural collapse, flashover, or other catastrophic events that can quickly compromise a safe working area. This accountability system underpins all operational decisions made by the Incident Commander.
Standard Triggers for Initiating a PAR Check
The Incident Commander calls for a PAR check following specific events or conditions that indicate a potential change in the risk level for personnel. These triggers ensure accountability is re-established immediately after high-risk moments or at regular intervals.
- Change in Operational Mode: When operations shift, such as moving from an aggressive interior attack (offensive) to an exterior water application (defensive).
- Report of a Mayday or Missing Person: Any report that a firefighter is missing, trapped, or in distress requires an immediate full accountability check.
- Significant Hazardous Event: Events like an explosion, unexpected flashover, or a confirmed structural collapse mandate an immediate PAR to check the status of personnel in the affected zone.
- Time Interval Benchmark: Accountability checks are commonly required every 20 to 30 minutes of elapsed time to ensure continuous monitoring.
- Tactical Benchmarks: Completion of a major tactical goal, such as the fire being reported “under control” or the primary search of a structure being declared complete, also triggers a formal report.
The Mechanics of Conducting a PAR Check
Executing a PAR check follows a specific, hierarchical chain of communication to maintain order on the radio channels. The process begins when the Incident Commander announces the PAR request to all operating units on the fireground. This request is then relayed down the command structure to the various Divisions or Group Supervisors managing specific sectors of the incident.
Company Officers visually account for every member before transmitting their report. The formal radio traffic must confirm three pieces of information: the unit’s designation, the number of personnel, and their confirmed status. This tiered communication ensures that accountability is verified at the lowest level before being reported up the chain to the IC.
Essential Accountability Systems Supporting PAR
Personnel tracking is supported by physical, non-radio systems that maintain accountability between mandatory radio checks. The most common manual method is the “Passport” or “Tag” system, utilizing plastic Personnel Accountability Tags (PATs). These tags are secured to a firefighter’s helmet and contain their name and unit designation.
Upon entering a high-risk area, a firefighter’s tag is collected and placed onto a central accountability board. Modern systems also utilize Self-Contained Breathing Apparatus (SCBA) telemetry integrated into the air pack. This technology transmits real-time data, such as air pressure, battery status, and Personal Alert Safety System (PASS) alarm activation, directly to the Incident Commander’s monitoring device.
Emergency Procedures When PAR is Incomplete
An incomplete or failed PAR check immediately elevates the incident status. If a Company Officer cannot account for crew members, or if a unit fails to respond, the Incident Commander must immediately declare a “Mayday.” This declaration signals a loss of personnel accountability and requires all other fireground traffic to cease, dedicating the radio channel to the emergency.
The immediate consequence is the activation and deployment of the Rapid Intervention Team (RIT), a crew staged for firefighter rescue. The RIT is deployed to the last known location of the missing personnel to initiate a search and rescue operation. An incomplete PAR is an immediate trigger for high-risk rescue actions aimed at recovering the unaccounted-for member.
