ATF teams for fire-cause determination on large-scale incidents typically comprise about how many agents?

• A. 5
• B. 10
• C. 20
• D. 15

Answer: (D)

When a fire is large and complex, ATF assigns a substantial Fire-Cause Team to thoroughly determine origin and cause, coordinate with other agencies, and manage evidence and scene safety. About 15 agents is the typical size because that allows enough investigators to cover multiple areas of the scene, run parallel interviews and evidence collection, and still have specialists for accelerants, reconstruction, and documentation. With roughly this many personnel, you can maintain a clear chain of custody, support labs and the medical examiner, and keep the investigation progressing without overloading any one role. Smaller teams—such as five—would lack sufficient coverage for a broad area, while ten could be tight for a complex, multi-area ignition search, and twenty would often exceed what's routinely deployed for standard large-scale incidents. Fifteen strikes a practical balance and is the common benchmark for large-fire investigations.
