ISO 45001:2018 Occupational Health & Safety Management System

ISO 45001 is an internationally recognized standard for occupational health and safety management systems (OHSMS). It provides a framework for organizations to proactively manage and improve their occupational health and safety performance, ensuring the well-being and safety of their employees and stakeholders.


ISO 45001 was developed to replace the previous standard, OHSAS 18001, and aligns with other widely adopted management system standards, such as ISO 9001 (quality management) and ISO 14001 (environmental management).


The key principles of ISO 45001 include:


  1. Hazard Identification and Risk Assessment: Organizations are required to systematically identify and assess occupational health and safety hazards, evaluate associated risks, and implement appropriate control measures to mitigate those risks.
  2. Legal Compliance: Compliance with applicable health and safety laws, regulations, and other requirements is an integral part of ISO 45001. Organizations must establish processes to monitor and ensure compliance with relevant legal obligations including Title 8.
  3. Objectives and Targets: Establishing measurable objectives and targets is essential to drive continual improvement in occupational health and safety performance. These objectives should be consistent with the organization’s policy and take into account legal requirements and industry best practices.
  4. Employee Participation: ISO 45001 emphasizes the importance of engaging and involving employees at all levels in the development, implementation, and continuous improvement of the OHSMS through participation and consultation. This includes communication and the provision of relevant training and resources.
  5. Performance Evaluation: Regular monitoring, measurement, and evaluation of occupational health and safety performance are crucial to identify areas for improvement and ensure that control measures remain effective. Incident investigation and analysis are also important for learning from past incidents and preventing future occurrences.
  6. Management Review: Top management plays a critical role in driving the success of the OHSMS. Regular management reviews are conducted to evaluate the system’s performance, assess the effectiveness of control measures, and make informed decisions for improvement.


Implementing ISO 45001 helps organizations create a safe and healthy work environment, prevent work-related injuries and illnesses, and reduce the risk of accidents and incidents. It demonstrates a commitment to employee well-being, legal compliance, and continuous improvement in occupational health and safety management.


ISO 45001 certification is achieved through an independent audit by a certification body. It provides external validation of an organization’s conformity to the standard and its ability to effectively manage occupational health and safety.


By adopting ISO 45001, organizations can enhance their reputation, gain a competitive advantage, and build trust among employees, customers, regulators, and other stakeholders. It also helps organizations meet legal requirements, reduce costs associated with accidents and incidents, and improve overall organizational performance.
