Interview for Understanding, Not Confirmation

Know the hazard

Team: Safety Workers. Topic: Incident Learning.

An incident interview should help us understand the work as the person experienced it. Start by explaining the purpose, who will receive the information, and any limits on confidentiality. Do not promise secrecy that the company cannot maintain. Ask the person to describe the task from the last point they remember clearly. Give them time to speak before presenting photographs, theories, or other witness accounts that might influence their recollection.

Use the controls

Use open questions about conditions and decisions. Ask what information was available, what they expected to happen, and what made the chosen method seem workable. Avoid questions that contain the desired answer, such as asking why they ignored an obvious rule. A person may not have seen the condition that now looks clear in a photograph. Record important wording accurately, separate your interpretation, and invite the witness to correct factual mistakes in your summary.

Work within the safe plan

End by asking what else should be examined and what would make the task safer. Do not require someone to diagnose a technical failure beyond their knowledge. Keep separate interviews separate until accounts are documented, and check discrepancies against other evidence rather than assuming dishonesty. Provide a route for later additions because details may return after the first conversation. A useful interview respects the person while still testing facts carefully; respectful listening and rigorous investigation belong together.

Discuss with the crew

Two witnesses give different estimates of when an alarm began.

Question: Does a difference prove someone is lying?
Answer guidance: No. Memory, position, distraction, and time estimates can differ.

Question: What evidence could help?
Answer guidance: Alarm logs, synchronized equipment records, and independently documented accounts.

Prepare, act, and follow up

Leader preparation: Prepare a private interview location and neutral opening question.

Put it into practice: Practice replacing three leading questions with neutral questions about work conditions.

Supervisor follow-up: Review interview summaries for assumptions presented as facts.
