The situation

What has happened

On 30 August a visitor was found walking unescorted between the depot office and the vehicle compound at the Rockhampton depot. The event was recorded in the WHS Incident and Hazard Register, the visitor was escorted out and the security officer was told within 24 hours. The customer has now asked for a formal administrative inquiry into how it happened and whether the escort requirement in the Security Policy is being followed at that site. Marcus Thorne has appointed you as inquiry officer with Tom Whitlock as adviser. The visitor register, the key and access card register, the site induction records and the staff involved are available to you.

Your brief. Conduct a fair, evidence based administrative inquiry that establishes what happened, why the escort requirement failed, whether the policy and procedure are adequate, and what corrective actions are recommended, and report to the General Manager in a form suitable for the customer.

What to look for

Evidence guide

Look for terms of reference approved before evidence gathering, interviews conducted and recorded fairly with the person told the purpose, findings that rest on the evidence collected, a clear separation of fact from opinion, corrective actions that address root cause rather than blame and a report that protects personal details while giving the customer what it asked for.

The student's evidence summary lists every record they created or changed in the systems named above, their notes and the tasks they ticked. Verify it against the deliverables and your own assessment tool.
