Organizations using OHSAS 18001:2007 are recommended to take the following actions for the migration to ISO 45001:2018 from OHSAS 18001:2007:
i) Obtain a copy of ISO 45001 (or a copy of the earlier Final Draft International Standard if early planning and adaptation is preferred).
ii) Identify the gaps in the OHSMS which need to be addressed to meet any new requirements.
iii) Develop an implementation plan.
iv) Ensure that any new competence needs are met and create awareness for all parties that have an impact on the effectiveness of the OHSMS.
v) Update the existing OHSMS to meet the new requirements and provide verification of its effectiveness.
vi) Where applicable, liaise with their Certification Body for migration arrangements.
