Manage OH&S risks with OHSAS 18001.

OHSAS 18001 was developed to help organisations better manage hazards in the workplace. Attention is now shifting from OHSAS 18001 to ISO 45001, the new international standard for occupational health and safety.

OHSAS 18001:2007 was developed in response to demand for a recognisable health and safety management system standard that could be externally assessed and certified.

With OH&S management extending to global organisations and complex supply chains, an international standard was needed to ensure a consistent approach for workers worldwide. The new international OH&S standard, ISO 45001:2018, was published on 12 March 2018 with organisations certified to OHSAS 18001 given a three-year migration period from the date of publication.

ISO 45001 combines the technical strength of existing OH&S standards, including OHSAS 18001, with the high-level structure of other international standards like ISO 9001 (Quality) and ISO 14001 (Environment) to make it easier to integrate into higher-level business management systems.
