WHAT ARE THE MAJOR DIFFERENCES BETWEEN OHSAS 18001 AND ISO 45001?

There are many differences, but the main change is that ISO 45001 concentrates on the interaction between an organization and its business environment while OHSAS 18001 was focused on managing OH&S hazards and other internal issues. But the standards also diverge in many other ways:

• ISO 45001 is process-based – OHSAS 18001 is procedure-based
• ISO 45001 is dynamic in all clauses – OHSAS 18001 is not
• ISO 45001 considers both risk and opportunities – OHSAS 18001 deals exclusively with risk
• ISO 45001 includes the views of interested parties – OHSAS 18001 does not

These points represent a significant shift in the way health and safety management is perceived. OH&S is no longer treated as a “stand alone”, but must be viewed within the perspective of running a sound and sustainable organization. That being said, although the two standards differ in their approach, a management system established in accordance with OHSAS 18001 will be a solid platform for migrating to ISO 45001.
