• A. ICS
• B. Personnel Accountability System
• C. IDLH
• D. Inverter

Answer: (B)

Identifying which emergency responders are working on an incident scene is managed through a Personnel Accountability System. This system records who has arrived at the scene, where they are, what assignment they have, and their current status. The goal is to maintain up-to-date awareness of every responder’s location and duty so that supervisors can quickly determine who is on scene, who is assigned to critical tasks, and who may be in danger or missing. At the scene, responders check in, and supervisors compile regular accountability reports (PARs) that roll up into the incident command structure. This keeps everyone informed as units rotate, ensuring rapid intervention if someone becomes trapped or unable to respond. While the Incident Command System provides the overall framework for managing an incident, the specific method for tracking personnel on the scene is the Personnel Accountability System. The other terms are unrelated to this specific function—IDLH refers to hazardous atmospheres, and an inverter is a device with no role in incident accountability.
