Internal HSQE Audits

ISO 9001:2015 Clause 9.2 · ISO 14001:2015 Clause 9.2 · ISO 45001:2018 Clause 9.2 — Internal audit programme

Procedure overview
A M Water Services operates an internal audit programme that verifies every section of the IMS is implemented, effective, and conforms to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. The HSQE Consultant programmes audits with frequency set on importance of activity and previous audit results — minimum once per IMS section per audit cycle, more frequent for high-risk areas or sections with prior non-conformances. Each audit is performed by a qualified auditor who is independent of the area being audited (Sean Ashton for most audits as external HSQE Consultant; rotation to other competent auditors where the consultant has been involved in design of the area). Findings that don't comply with planned arrangements raise non-conformances; root causes are identified, corrective actions are agreed with the auditee, completion is tracked to closure, and effectiveness is verified before close-out. The audit programme outputs feed the Management Review (SOP 6.4) and Continual Improvement (SOP 7.2) cycles. Records are retained per SOP 4.7.

Auditor independence and audit-frequency rules
Independence: An auditor must not audit work for which they are also responsible (have authored, designed, supervised or implemented). Where Sean Ashton has been involved in drafting the area being audited (e.g. authoring a policy or RAMS), the audit of that area is delegated to a different competent auditor: rotation between the Director (MD) acting as auditor for HSQE-consultant-authored content, an external peer reviewer, or a client's auditor where contractual arrangements permit. Frequency: Minimum once per IMS section per audit cycle; high-risk operational sections (RAMS implementation, COSHH, work-at-height, confined space, asbestos) audited at least twice per cycle. Sections with an open major non-conformance or two open minor non-conformances move to quarterly until cleared. The audit cycle is annual; the rolling programme is reviewed at every Management Review.
