Which of the following describes when a debrief should occur?

• A. After an incident
• B. During an incident
• C. Before an incident
• D. Never

Answer: (A)

Debriefs are most effective after an incident has concluded. Once the situation is contained and data, logs, and evidence are available, participants can calmly recount what happened, why decisions were made, and what outcomes resulted. This timing reduces memory bias and allows for a comprehensive, accurate discussion of both strengths and areas for improvement, so procedures and training can be refined for the future. Debriefing during an incident is risky because information is still evolving and stress can distort memories, making it hard to identify lessons clearly. Debriefing before an incident doesn’t fit because there’s nothing real to review yet, and “never” isn’t appropriate because learning from actual events is a standard practice.
