I posted this in the OHS Forum but didn't get much traction so I am posting it here. During a CB audit of an ISO 9001/OHSAS 18001 certified construction company, a Minor NC was raised because: the internal audit records showed that the company's Safety Supervisor was part of the team that audited the operational controls at the construction project sites. The team composed of the Lead Internal Auditor, appointed internal auditors and the Safety Supervisor. According to the CB auditor, having the Safety Supervisor as part of the team violates the requirement that "Auditors shall not audit their own work." We appealed that the Safety Supervisor only acted as a technical resource person of the audit team and did not perform the actual audit. Each construction project site has at least two (2) Safety Officers assigned to ensure operational controls are established and implemented. These Safety Officers report to the Safety Supervisor. Was the finding of the CB auditor valid? What's your take on this?
