Migrating from OHSAS18001

The deadline for migrating from OHSAS18001:2007 to ISO45001:2018 is March 2021, although certified companies are encouraged to plan for an earlier migration. ISO45001 represents a root and branch overhaul of the previous document and brings the structure of the H&S standard in line with all other recently updated standards, including ISO9001 and ISO14001. 

The following are the main changes arising from the new standard (although there are numerous other changes throughout the document). If you are planning for migration or if you would like more information on what is involved, contact us and we would be happy to meet with you to explain the requirements, and the migration process in detail.


Context of the organization

This is a new requirement in ISO45001 and includes identifying the internal and external issues that could affect your ability to achieve your H&S objectives. Once identified, you must determine the risks and opportunities associated with these issues with a view to deciding where further work is required to address risk or realise opportunity.

The second key element of this new requirement is to identify the interested parties relevant to your management system and then determine their needs and expectations. Again, you need to assess your controls and decide where further work is required.


The new standard puts even greater emphasis on the accountability, responsibility and involvement of top management in the management system. 

Participation and consultation

The requirements relating to participation and consultation of workers are greatly enhanced in ISO45001 and mechanisms must be put in place to ensure participation and consultation takes place across a wide range of areas including context, policy, roles/responsibilities, compliance with legal/other obligations, procurement/contractor control, competence and communication.

Contractor control

There are tighter controls required in relation to contractors and outsourced processes.


There are changes to the communications requirements, including what is to be communicated and how. For example, diversity aspects (gender, literacy, culture etc.) and the views of interested parties must be considered when establishing communications processes.
