Comparative analysis between ISO 45001 (OHS) and ISO 9001 (QMS). Focus, stakeholders, risk assessment, operational controls, and integrated management system strategy.
ISO 45001 and ISO 9001 are the two most complementary management system standards for industrial and service organizations. ISO 9001:2015 establishes requirements for a quality management system (QMS) focused on customer satisfaction. ISO 45001:2018 establishes requirements for an occupational health and safety management system (OHSMS) focused on preventing work-related injuries and illnesses. Both share the High-Level Structure, facilitating their integration.
ISO 45001 and ISO 9001 are the pillars of any integrated management system (IMS) in industrial organizations. ISO 9001 ensures what you produce meets customer requirements; ISO 45001 ensures the process to produce it does not endanger anyone's life. Thanks to the shared High-Level Structure, integration is natural: management review, internal audit program, nonconformity management, and document control are unified.
Yes, and it is the most recommended practice. Both standards share the High-Level Structure (clauses 4-10 identical in structure), allowing unification of: integrated policy, objectives, management review, internal audits, nonconformity management, and corrective actions. The result is a more efficient system with less documentation burden.
Yes. OHSAS 18001 was withdrawn in March 2021. ISO 45001:2018 is its official successor and the only current certifiable international OHS standard. Key differences: ISO 45001 requires active worker participation, adopts the High-Level Structure for integration, and has a stronger focus on organizational context and leadership.
