ISO 45001:2018 is an international standard that specifies the requirements for an occupational health and safety (OH&S) management system. This standard aims to help organizations provide a safe and healthy workplace by preventing work-related injury and ill health, as well as by proactively improving its OH&S performance.

Here are some key elements and requirements of ISO 45001:2018:

2. **Leadership and Worker Participation**: Top management is responsible for the effectiveness of the OH&S management system and must demonstrate leadership and commitment to OH&S. Worker participation is also emphasized to ensure that workers are involved in the development, implementation, and continual improvement of the OH&S management system.

3. **Planning**: Organizations must identify and assess OH&S risks and opportunities, establish OH&S objectives and plans to achieve them, and integrate the OH&S management system into the organization’s overall business processes.

4. **Support**: This section covers the resources, competence, awareness, communication, and documented information required to support the OH&S management system.

5. **Operation**: This involves implementing the planned actions, controlling the OH&S risks, and managing the processes needed to achieve the OH&S objectives.

6. **Performance Evaluation**: Organizations must monitor, measure, analyze, and evaluate their OH&S performance, and take necessary actions to achieve continual improvement.

7. **Improvement**: This section emphasizes the need for continual improvement of the OH&S management system’s suitability, adequacy, and effectiveness.
