ISO 45001 Implementation in 33-steps


A valuable aid to your developing a viable OHSMS Project Plan - to aid you start on time, finish on time and leave nothing vital out.

The ISO 45001:2018 Implementation Model developed by deGRANDSON Global

The 33 Steps to ISO 45001 Implementation is the model we have developed for implementing an Occupational Health & Safety Management System (OHSMS) to meet the requirements of ISO 45001:2018 and to securing accredited Certification.

It is the foundation on which our Lead Implementer Course and OHSMS Transition Course are built.

So where does it come from?

Path to ISO 45001 Certification

The International Standards Organisation (ISO) has published one standard only that focuses on developing and implementing an organization's OHSMS. But it divides into two parts:

  • The OH&S Management System Standard, ISO 45001:2018:  This standard is the specification for an OHSMS. It specifies the requirements of an OH&S management system for organizations seeking to establish implement and maintain a framework for the occupational health and safety of workers and others who can be affected by its activities. And to promote and protect their physical and mental health.
  • ISO 45001:2018, Annex A: Guidance on the use of this document. We mention this Annex to the Standard separately as it is often ignored and the very useful guidance it contains not studied.

To help make sense of it all from an OHSMS Implementer/Project Manager’s viewpoint we have developed the 33-Step Infographic that you can see above.
