OHSAS 18001 was a British standard that outlined the requirements for an Occupational Health and Safety Management System (OHSMS). It provided a framework for managing occupational health and safety risks and improving performance. It was replaced by the new international standard ISO 45001:2018, which was published in March 2018.
ISO 45001 is an international standard that replaces OHSAS 18001 as the primary standard for occupational health and safety management systems. ISO 45001 provides a more holistic and systematic approach to managing occupational health and safety risks, emphasizing the need for leadership commitment, participation of workers, and the integration of the OHSMS into the overall business processes. It also includes a stronger emphasis on the prevention of injury and ill health, as well as the continuous improvement of the OHSMS.
Some of the key differences between OHSAS 18001 and ISO 45001 include:
- Scope: ISO 45001 applies to all types of organizations, regardless of their size, sector, or nature of the work, whereas OHSAS 18001 was primarily aimed at manufacturing and service organizations.
- Context of the organization: ISO 45001 requires organizations to consider the internal and external context in which they operate, including the needs and expectations of interested parties and the impact of their activities on the environment, whereas OHSAS 18001 did not have such a requirement.
- Leadership and worker participation: ISO 45001 places a stronger emphasis on leadership commitment and the participation of workers in the development and implementation of the OHSMS, whereas OHSAS 18001 did not specify such requirements.
- Risk-based approach: ISO 45001 requires organizations to take a risk-based approach to managing occupational health and safety risks, whereas OHSAS 18001 only required a hazard-based approach.
- Performance evaluation: ISO 45001 requires organizations to monitor, measure, analyze, and evaluate the performance of the OHSMS, whereas OHSAS 18001 did not provide specific requirements for performance evaluation.
Overall, ISO 45001 is a more comprehensive and modern standard that provides a framework for managing occupational health and safety risks and improving performance in a more integrated and systematic way.
