The core purpose of ISO 45001 is to prevent work-related injuries, illnesses, and fatalities by fostering a proactive approach to occupational health and safety. It aims to create safer work environments by requiring organizations to systematically identify and control hazards, such as unsafe machinery, ergonomic risks, or psychosocial stressors, before they cause harm. By emphasizing risk-based thinking and worker participation, the standard ensures that safety measures are practical and tailored to specific workplace conditions, protecting employees, contractors, and visitors.

Beyond safety, ISO 45001 seeks to enhance organizational resilience and efficiency by reducing workplace incidents and their associated costs, such as medical expenses, downtime, or legal liabilities. The standard promotes a culture of continual improvement, encouraging organizations to regularly evaluate and refine their safety practices to adapt to changing conditions, new technologies, or regulatory updates.

The ISO 45001 standard is an internationally recognized framework for occupational health and safety management systems (OHSMS), designed to help organizations proactively manage workplace health and safety risks. Published in 2018 by the International Organization for Standardization (ISO), ISO 45001:2018 replaced OHSAS 18001 and aligns with the high-level structure of other ISO standards, such as ISO 9001 and ISO 14001, facilitating integration. It applies to organizations of all sizes and sectors, from construction to office environments, and emphasizes worker participation, risk prevention, and compliance with legal and regulatory requirements. By providing a systematic approach to identifying hazards, assessing risks, and implementing controls, ISO 45001 helps organizations create safer workplaces and reduce occupational injuries and illnesses.

ISO 45001 is structured around 10 clauses, focusing on leadership commitment, worker involvement, and continual improvement. Key requirements include identifying workplace hazards and assessing risks (clause 6.1), establishing operational controls (clause 8.1), and preparing for emergencies (clause 8.2). The standard mandates active consultation with workers (clause 5.4) and requires organizations to monitor performance through audits and reviews (clauses 9.2 and 9.3).
