Full title and description

ISO 45001:2018 — Occupational health and safety management systems — Requirements with guidance for use. An international management‑system standard that specifies requirements and guidance to help organizations establish, implement, maintain and continually improve an occupational health and safety (OH&S) management system to prevent work‑related injury and ill health and to proactively improve OH&S performance.

Abstract

ISO 45001:2018 defines a risk‑based framework (aligned with the ISO high‑level structure and PDCA — Plan‑Do‑Check‑Act) placing emphasis on leadership, worker participation and the context of the organization. It requires hazard identification, assessment and controls, legal and other requirements management, objective setting and continual improvement of OH&S performance. The standard is intended to be applicable across sectors and organization sizes.

Scope

ISO 45001:2018 specifies requirements for an occupational health and safety (OH&S) management system and provides guidance for its use so organizations can provide safe and healthy workplaces by preventing work‑related injury and ill health, eliminating hazards and minimizing OH&S risks (including system deficiencies), and proactively improving OH&S performance. It is intended to be applicable to any organization regardless of size, type or sector.

Key topics and requirements

• Context of the organization: identify internal/external issues and interested parties that affect OH&S management.
• Leadership and worker participation: top management accountability and active worker consultation and participation.
• Risk‑based thinking and hazard identification: assess hazards, determine OH&S risks and opportunities, and establish controls.
• Legal and other requirements: identify, access and maintain compliance obligations.
• Planning and objectives: set OH&S objectives, plan actions to achieve them and address risks and opportunities.
• Support and competence: resources, training, awareness, communication and documented information.
• Operational controls and emergency preparedness: implement controls, manage change and prepare for emergencies.
• Performance evaluation: monitoring, measurement, internal audit and management review.
• Improvement: incident investigation, corrective actions, continual improvement of the OH&S management system.
• Integration and alignment: designed for integration with other ISO management system standards (e.g., ISO 9001, ISO 14001) through the common high‑level structure.

Typical use and users

Organizations of any size and sector implement ISO 45001 to manage workplace health and safety — especially in higher‑risk sectors such as construction, manufacturing, mining, oil & gas, transportation and healthcare. Primary users include corporate leadership, OH&S managers, safety professionals, internal and external auditors, certification bodies and consultants. Organizations may implement the standard with or without seeking third‑party certification.

Related standards

Key related documents and standards include OHSAS 18001 (the predecessor now superseded by ISO 45001), ISO 45002:2023 (general guidelines for implementing ISO 45001), ISO 45003:2021 (guidance on psychosocial risk management), the 2024 Amendment ISO 45001:2018/Amd 1:2024 (climate action changes), and other management‑system standards such as ISO 9001 and ISO 14001 for integrated management approaches.

Q: What does it cover?

A: It covers the full OH&S management‑system cycle: context, leadership and worker participation, planning, support, operation, performance evaluation and improvement — with requirements for hazard identification, risk assessment and control, legal compliance, objectives and continual improvement.

Q: Who typically uses it?

A: Organizations of any size and sector (notably high‑risk industries such as construction, manufacturing, mining and healthcare), OH&S professionals, managers, internal/external auditors, certification bodies and consultants. Organizations can implement it for best practice or pursue third‑party certification.

Q: Is it current or superseded?

A: ISO 45001:2018 is the current international OH&S management system standard.

The standard is subject to periodic review and work on future revisions is ongoing.

Q: Is it part of a series?

A: Yes — ISO 45001 is supported by related guidance and normative documents (for example ISO 45002:2023 for implementation guidance and ISO 45003:2021 for psychosocial risk guidance), plus national adoptions and amendments that together form the ISO family of OH&S documents.
