ISO 45001:2018 Occupational Health and Safety Management System — Clause Reference 2026

ISO 45001:2018 is the international standard for Occupational Health and Safety (OHS) management systems. Published by the International Organization for Standardization (ISO) in March 2018, it replaced OHSAS 18001 and follows the Annex SL high-level structure common to other ISO management system standards (ISO 9001, ISO 14001). The standard provides a framework for organizations to proactively improve OHS performance, prevent work-related injury and ill health, and provide safe and healthy workplaces. This dataset is a structured reference summary of clauses 4 through 10, covering Context of the Organization, Leadership, Planning, Support, Operation, Performance Evaluation, and Improvement. Each record maps the clause number and title to a brief statement of intent, a summary of key requirements, and the corresponding Plan-Do-Check-Act (PDCA) phase. The dataset is intended to support OHS professionals, auditors, consultants, and software developers in navigating the standard's structure quickly. This is a reference summary only — it is not a reproduction of the ISO 45001:2018 standard text, which is copyrighted by ISO. Clause titles and structural descriptions are derived from publicly available summaries, Annex SL documentation, and established interpretive guidance. Users should always verify requirements against the official ISO 45001:2018 publication obtained from ISO or an authorized national standards body (e.g., BSI, ANSI, SAI Global). Clause intent and requirement summaries in this dataset represent common professional interpretation and not the authoritative normative text. Dataset covers 30 clause and subclause entries spanning the normative body of the standard. Related standards include ISO 45002:2023 (implementation guidelines), ISO 45003:2021 (psychological safety), and ISO 45004:2021 (performance evaluation). The Annex SL structure means clauses 4–10 are structurally aligned with ISO 9001:2015 and ISO 14001:2015, enabling integrated management systems.
