ISO 45001 | Health & Safety Certification | NQA | NQA

ISO 45001, the replacement of OHSAS 18001, has now reached Draft International Standard 2 (DIS 2) status.

Please note: ISO 45001 delayed - read more here.

WHAT IS ISO 45001?

ISO 45001 is the future replacement to OHSAS 18001 and will become the ISO standard for Occupational Health and Safety Management Systems (OHSMS).

Not only will the standard supercede OHSAS 18001, it will make integration with other management systems simpler than ever before; because it shares the new common structure defined by Annex SL, it is directly aligned with the 2015 versions of ISO 9001 and ISO 14001. 

You can find more information about migrating to ISO 45001 in the briefing note HERE.


If you have certification to OHSAS 18001 you will need to migrate to ISO 45001 to maintain the validity of certification.

ISO 45001 is expected to be published in the first half of 2018, so there is plenty of time to plan the migration.

We will keep you informed of significant changes and updates but don't expect to have detailed plans until the Final Draft Standard has been published. 


Because ISO 45001 has to be agreed globally, do you think it will be a 'watered down' version of OHSAS 18001? No – it is a new standard using an established structure based on an effective management model, it is designed to be used as part of a business management system.

Legislation registers / Aspects and Impacts Registers: Is there a minimum requirement for what they must contain? No – the contents will be based on the business activity, geographical location and local /national enforcement requirements. Each organisation is unique.

If we adopt the new standard now (before we are able to migrate) will the organisation still be able to meet the requirements of OHSAS 18001 and hence maintain certification? The clause by clause requirements for the existing OHSAS 18001 are established and can be used for registration – the draft 45001 standard is not approved but there will be common elements, however as the draft ISO standard is still subject to potential change – to be sure, use what is currently approved- OHSAS 18001. Refinements can be made without compromising the integrity of an existing 18001 system.


We have published a video briefing from Charles Corrie the Secretary of OHSAS Project Group. He explains:

  • Why an ISO standard is being developed
  • The process and timescales (potentially published in 2017)
  • Three new concepts being introduced
  • The potential impact on organizations with OHSAS 18001 certification.
