The importance of “health” has now been given greater emphasis.

OHSAS 18001 now refers to itself as a standard, not a specification, or document, as in the earlier edition. This reflects the increasing adoption of OHSAS 18001 as the basis for national standards on occupational health and safety management systems.

Significant improvement in alignment with ISO 14001:2004 throughout the standard,
and improved compatibility with ISO 9001:2000.

It is now considered that such “damage” is not directly related to occupational health and safety management, which is the purpose of this OHSAS Standard, and that it is included in the field of asset management. Instead, the risk of such damage having an effect on occupational health and safety should be identified through the organization’s risk assessment process, and be controlled through the application of appropriate risk controls.

Management of change is now more explicitly addressed.

A new clause on the Evaluation of compliance has been introduced, as per ISO 14001:2004

OHSAS 18001 has been changed to become ISO 45001

ISO 45001:2016 is the new international standard for occupational health and safety (OHS) management systems and has replaced the existing OHSAS 18001:2007 standard.
