Which of the following is NOT one of the three personnel accountability systems?

The personnel accountability systems are crucial for ensuring the safety of firefighters and other emergency responders during operations. There are generally three recognized types of personnel accountability systems: the passport system, SCBA tags, and various computer-based electronic systems.

The passport system typically involves the physical tracking of personnel by using a tag or badge that is checked in and out at the command post. SCBA tags serve a similar purpose, specifically tracking the movement and status of individuals assigned to use self-contained breathing apparatus. Computer-based electronic systems offer a more modern approach to accountability, utilizing technology to monitor personnel location and status efficiently.

An incident report system, while vital for documenting events and assessing outcomes of incidents, does not function as an accountability system during active firefighting or emergency response. It is more focused on logging activities for later review rather than providing real-time accountability of personnel on the scene. Therefore, it is not classified as one of the primary systems used to ensure personnel are accounted for during operations. This distinction highlights the key function of accountability systems in maintaining safety and coordination in emergency situations.
