Document Control

ISO 9001:2015 Clause 7.5 · ISO 14001:2015 Clause 7.5 · ISO 45001:2018 Clause 7.5 — Documented information; control of documents of internal and external origin

Procedure overview
A M Water Services controls two distinct document populations: internal documents — manuals, policies, SOPs, appendices, registers and forms produced and owned by AMWS — and external documents — ISO standards, BSI standards, regulatory codes of practice, water-industry specifications and client documents. Internal documents are produced by the HSQE Consultant in the AMWS format (document reference, issue number, issue date), reviewed and approved by the Directors, uploaded to the controlled IMS portal, and recorded in the Master Document & Record Index. External documents are tracked for currency through subscription services or periodic checks; superseded versions are removed from circulation and the index is updated. The IMS portal is the master source for all controlled documents (per MAN_01); printed copies are uncontrolled and must be checked against the portal before use. Records are retained per SOP 4.7.

Single source of truth — the IMS portal
The IMS portal at amwaterservices.onyxoperations.co.uk is the master source for every controlled internal document. Printed or downloaded copies are uncontrolled — they may be out of date the moment they leave the portal. Where a controlled document must be used in the field (e.g. a method statement on a tablet, a COSHH sheet on a van), the version reference shown on the document must be checked against the portal before use. Obsolete versions retained for archive purposes are clearly marked "OBSOLETE — FOR REFERENCE ONLY" and segregated from current documents on the portal under the relevant document's change-log table. The Master Document & Record Index is the single canonical list of all current controlled documents and their current issue numbers; if it disagrees with what's on the portal, the index wins and the portal is corrected.
