Migration to ISO 45001 Organizations Using OHSAS 18001:2007

For any organisation, the degree of change necessary will be dependent upon the maturity and effectiveness of the current management system and organisational structure and practices. Therefore, an impact analysis/gap assessment is strongly recommended in order to identify realistic resource and time implications.

Organizations using OHSAS 18001:2007 are recommended to take the following actions:

  • Obtain a copy of ISO 45001 (or a copy of the earlier Final Draft International Standard if early planning and adaptation is preferred).

  • Identify the gaps in the OHSMS which need to be addressed to meet any new requirements.

  • Develop an implementation plan.

  • Ensure that any new competence needs are met and create awareness for all parties that have an impact on the effectiveness of the OHSMS.

  • Update the existing OHSMS to meet the new requirements and provide verification of its effectiveness.

  • Where applicable, liaise with their Certification Body for migration arrangements.

NOTE: Users should be aware that technical changes can occur in the development of a standard following the Draft International Standard (DIS) or later draft stage document before the International Standard (IS). While organizations can start their preparations at the DIS or later draft stage document before the IS, significant changes to the OHSMS should not be implemented until the technical content is finalized, i.e. either at the Final Draft International Standard (FDIS) stage, or when the standard is published. ISOCert does not provide any consultancy services. This information is merely a guideline for organisations on what to expect and how to plan for the migration.
