Occupational Health & Safety Management
International standard for occupational health and safety management systems. Provides a framework for managing OH&S risks, preventing work-related injury and ill health, and promoting safe workplaces.
ISO 45001 is the international standard for occupational health and safety management systems, replacing OHSAS 18001 globally. It establishes a proactive framework for preventing work-related injury and ill health, managing OH&S risks and opportunities, and promoting safe and healthy workplaces.
A key distinction from OHSAS 18001 is ISO 45001's emphasis on worker participation, the integration of OH&S into organisational strategy, and the explicit requirement for top management leadership. The Annex SL structure enables seamless integration with ISO 9001 and ISO 14001.
ACI-certified ISO 45001 auditors are equipped to assess OH&S management system design and effectiveness, evaluate hazard elimination and risk-reduction controls, and review worker participation mechanisms.
