Workplace incident investigation checklist

Use the investigation findings to develop specific, measurable corrective actions that address both immediate and root causes. For each identified hazard or system failure, create actions that eliminate or control the risk. The checklist’s structured format helps you link each corrective action directly to investigation findings. Prioritize actions based on severity and likelihood of recurrence, and assign clear responsibility with reasonable deadlines for implementation.

Document all perspectives without showing bias toward any particular account. Note specific points of agreement and disagreement between witnesses. Consider factors that might affect perception such as viewing angle, lighting, or distance from the incident. Sometimes conflicting accounts reveal important details that a single perspective might miss. The investigation team should analyze these differences to develop the most accurate understanding of what occurred.

Apply the same thorough approach you would for an actual injury. Near-misses are valuable learning opportunities without the associated harm. Document what happened, what could have happened, and what prevented the worst outcome. The checklist helps you identify the barriers that worked and those that failed. Investigating near-misses often reveals hazards before they cause injuries, making them essential for proactive safety management.

Document the violations objectively as factors contributing to the incident without using accusatory language. Focus on the system that allowed the violation to occur rather than individual blame. Consider whether procedures were clear, training was adequate, and compliance was regularly monitored. The checklist aids you in separating intentional violations from those caused by confusion, inadequate resources, or production pressure.
