The safety investigation process is a formal process for investigating a workplace incident, including a fatality, injury, illness, or close call. This enables you to discover hazards in business operations and drawbacks in health and safety programs. With the learnings from the investigation, you can implement appropriate corrective and preventive actions to avoid future incidents. While conducting the safety investigation process, the team should do a Root Cause Analysis (RCA) of the incident to ensure the real reason is identified and controls put in place to prevent its recurrence.
