The purpose of the Stage One audit is to assess the organization’s readiness for certification. This stage includes reviewing environmental documentation and policies, verifying understanding of ISO 45001:2018 requirements, and confirming their initial implementation, while identifying any gaps that need to be addressed before moving to the next stage.

In this stage, the on-site audit is conducted, where auditors review the actual implementation of the environmental management system within the organization and verify full compliance with ISO 45001:2018 requirements. If no major nonconformities are found, or after they are closed, a recommendation is made to grant the certification.
