OHSAS 18001, Occupational Health and Safety Assessment Series (officially BS OHSAS 18001), was a British Standard for occupational health and safety management systems.

Compliance with it enabled organizations to demonstrate that they had a system in place for occupational health and safety.

BSI cancelled BS OHSAS 18001 to adopt ISO 45001 as BS ISO 45001. ISO 45001 was published in March 2018 by the International Organization for Standardization.

Organizations that are certified to BS OHSAS 18001 were able to migrate to ISO 45001 by March 2021 to retain a recognized certification

ISO 45001
For organizations that are serious about improving employee safety, reducing workplace risks and creating better, safer working conditions, there’s ISO 45001.

According to the International Labour Organization, more than 7 600 people die from work-related accidents or diseases every single day. That’s why an ISO committee of occupational health & safety experts set to work to develop an International Standard with the potential to save almost three million lives each year. Structured in a similar way to other ISO management systems, the approach will be familiar to users of standards such as ISO 14001 or ISO 9001. ISO 45001 builds on the success of earlier international standards in this area such as OHSAS 18001, the International Labour Organization’s ILO-OSH Guidelines, various national standards and the ILO’s international labour standards and conventions.
