ISO45001 and OHSAS18001: Updates & Key Changes

ISO45001 is the currently unpublished safety management systems standard that has been developed to replace the current OHSAS 18001 standard. The revised standard brings with it a range of changes, updates and a new approach to OHSAS management systems. The ISO45001 revision was approved and the first draft published back in 2014 and it is now nearly time for ISO45001 to be formally published with the new standard currently being expected to be published early 2018.


What is changing in ISO45001?

What this revision of the safety standard aims to do is to draw the safety management system closer to an organisations core operational processes. By further integrating the safety system to the organisations core activities ISO45001 aims to establish a strong safety culture. The newer version of the safety standard also asks for leadership from management across all levels and pushes consultation with those affected by the systems including employees and contractors as well.


What does this mean for my current OHSAS 18001 certification?

As ISO45001 is superseding OHSAS 18001 if your business is currently certified to OHSAS 18001 you will need to transition your certification to the new standard. The good news here is ISO45001 shares a majority of it’s framework with both AS/NZS4801 and OHSAS18001 so if your business is certified to or familiar with either of these standards the transition will be smoother. The new standard also follows the same Annex SL structure as the ISO9001:2015 and ISO14001:2015 revisions for ease of integration with your existing systems.

The final version of the standard is yet to be published but the new standard will include an additional focus on top management buy-in and safety culture that organisations can work towards creating in anticipation of the final publication;


  • Worker participation
  • Continual improvement
  • Hierarchy of control
  • Risk management (and emergency management)
  • Compliance status
  • Contractors, procurement and outsourcing


Keep an eye on our blog posts and emails for more information on the transition as the publication of the revised standard is finalised.
