ISO 45001, the world’s most anticipated standard for workplace health and safety (WHS) systems was published on 12 March 2018. This new Occupational Health and Safety (OHS) Management System standard is aligned with ISO 9001:2015 (Quality Management System) and ISO 14001:2015(Environment Management System) which have been designed based on High Level Structure (HLS). ISO 45001:2018 has been designed as an international standard which has been published by International Organisation for Standardisation (ISO) to replace the existing standards such as OHSAS 18001:2007.
In developing the standard, consideration has been given to the content of other international standards (such as OHSAS 18001 or the International Labour Organisation’s “ILO–OSH Guidelines”) and national standards (such as AS/NZS 4801), as well as to the ILO’s International Labour standards and conventions (ILSs).
OHSAS 18001 and most likely AS/NZS 4801:2001 will be withdrawn after the publication of ISO 45001. Organisations that are currently certified to OHSAS 18001 and/or AS/NZS 4801 will have a three-year window to upgrade their existing certificate to ISO 45001.
So, if your organisation is considering implementing this new standard, a useful starting point is to complete a gap assessment. It will help you understand which areas you already meet and where you will need to implement new approaches or activity to address the requirements. If your organisation is already certified to AS/NZS 4801:2001 and/or OHSAS 18001:2007, the gap assessment will also help you to understand the gaps and how to address them to upgrade your existing OHS system to a ISO 45001 compliant one.
Implementing an ISO 45001-based OH&S management system will enable an organisation to improve its OH&S performance by
There are many minor differences in the content of ISO 45001 compared to OHSAS 18001 and AS/NZS 4801, but the major differences can be summarised as:

As there is a three-year transition period for replacing OHSAS 18001 and AS/NZS 4801 with ISO 45001, if you are already certified to the current OHS standard, it is good timing for upgrading your system to ISO 45001, but if you have not achieved any OHS certificate so far, you can design your OHS management system based on the high-level structure and get certified to ISO 45001:2018 as soon as certification bodies become authorised to issue the ISO 45001:2018 certificate.
As a best practice approach, you may follow the following step-by-step phases.
We have designed our exclusive gap assessment tool which provides you not only the gaps and the area where you need to improve but also numerical and graphical analysis of your current compliance score and how you can increase your compliance level.
Please fill out the Questionnaire or contact us if you need our hands to assist you in developing and establishing your management system in compliance with the requirements of ISO 45001:2018 standard. We also offer a gap assessment service to find out how close you are to your ISO 45001:2018 certificate.
