Who should participate in post-incident debriefings?

• A. The general public.
• B. External community volunteers.
• C. Supervisors, responders, and relevant agencies.
• D. Only the lead investigator.

Answer: (C)

Post-incident debriefings are a collaborative review where those who directed the response and those who carried it out come together with the relevant agencies to evaluate what happened and how to improve next time. The best participants are supervisors, responders, and relevant agencies because they bring the full range of perspectives needed to understand decisions, actions, and coordination across units. Supervisors provide the command and policy context, responders share on-the-ground observations about tactics, timing, and safety, and relevant agencies ensure all involved agencies’ viewpoints are heard and that interagency procedures are aligned. This collective input helps identify gaps, refine protocols, and strengthen future responses.

Including the general public isn’t appropriate due to security and confidentiality concerns. External community volunteers aren’t typically part of this internal learning process for similar reasons, and having only the lead investigator would limit the debrief to a single viewpoint, missing operational and interagency insights that are essential for comprehensive improvement.
