What is the typical sequence of actions in an incident investigation after a safety event?

• A. Interview witnesses, secure the scene, identify root causes, collect evidence, and report.
• B. Secure the scene, collect evidence, interview witnesses, identify root causes, implement corrective actions, and report.
• C. Report first, then collect evidence, then interview witnesses.
• D. Immediately publish a report.

Answer: (B)

The sequence emphasizes preserving evidence and building the investigation step by step so findings are accurate and actionable. Start by securing the scene to prevent further harm and to stop loss or tampering of evidence. This protection sets the foundation for reliable data collection. Next, gather evidence—photos, measurements, logs, equipment, surveillance footage, and any physical items. Collecting evidence in a controlled, orderly way protects its integrity and creates a solid factual basis for analysis. Then interview witnesses, once the scene is secure and key materials are documented. Interviews help fill in timelines and clarify how events unfolded, but they’re more reliable after physical evidence is secured and recorded. With the evidence and accounts in hand, identify the root causes of the incident. This analysis goes beyond symptoms to determine why the event occurred, focusing on deficiencies in systems, processes, or controls. After pinpointing root causes, implement corrective actions to prevent recurrence. These actions should address the underlying issues uncovered during analysis and be tracked for effectiveness. Finally, report the investigation findings, actions taken, and recommendations. A formal report communicates what happened, why it happened, and how the organization will prevent future incidents. Other sequences tend to move too quickly to interviews or reporting before evidence is secured and analyzed, which can compromise objectivity and accuracy.
