Internal / external context, interested parties, scope of OH&S management system
Clause 4 is the foundational Annex SL clause that establishes the organisation's context — the internal and external issues that affect the OH&S management system, the interested parties (workers, contractors, regulators, communities, customers, suppliers), and the scope boundary that defines what the system covers. The clause is unique to the post-2015 Annex SL structure and is the entry point for ISO 45001 implementation.
Clause 4 forces the organisation to articulate its strategic OH&S context — the regulatory environment, the worker demographics, the contractor exposure, the community proximity, the cultural maturity. Organisations that take Clause 4 seriously build OH&S programmes calibrated to their actual situation rather than generic templates. Those that treat it as a checkbox build systems that don't reflect reality.
Clause 4 sets the strategic frame for every other ISO 45001 clause. Cl.5 leadership and Cl.6 planning both refer back to the context established here. Cl.4.4 specifically requires the OH&S management system to be established, implemented, maintained, and continually improved in accordance with the requirements of the standard — meaning Cl.4 is the integration anchor for the entire MS.
A focused 6-step methodology calibrated to deliver context of the organisation as a working capability — not a documented compliance artefact.
Per Cl.4.1, document organisational structure, governance, culture (Hudson maturity), capabilities, resources, knowledge; identify internal factors affecting OH&S outcomes.
Per Cl.4.1, document regulatory environment (Factory Act / OSHA / EU Directive / COMAH), political, economic, social, technological, legal factors; identify external risks and opportunities.
Per Cl.4.2, map interested parties — workers, contractors, regulators, community, customers, suppliers, investors; document needs and expectations per AA1000SES.
Per Cl.4.3, define OH&S management system boundary, activities, products / services covered; document any exclusions with justification; align with ISO 45001 Annex A guidance.
Per Cl.4.4, establish process approach, PDCA cycle, integration with other management systems via Annex SL; document in OH&S MS manual or equivalent.
Annually re-assess context, interested parties, and scope as part of management review per Cl.9.3; update when internal / external context changes materially.

We can scope this element implementation against your facility, regulatory context, and existing management-system maturity — and integrate it with the other ISO 45001 — Occupational Health & Safety Management System elements you already operate.
