ISO 45001:2018 is the international standard for occupational health and safety management systems. It replaced OHSAS 18001 and follows the Annex SL structure shared by ISO 9001 and ISO 14001 — making integration across quality, environment, and safety straightforward.
Clause 4 (Context) is where most audits find their first nonconformity. Clause 5 (Leadership) requires demonstrable top management commitment. Clause 6 (Planning) requires documented risk assessments. Clause 8 (Operation) covers day-to-day controls. Clause 9 (Performance Evaluation) mandates monitoring and internal audit. Clause 10 (Improvement) closes the loop with CAPA. See our [evidence collection guide](/guides/iso-45001-evidence-collection-guide).
