Certification Process
1
Application & Review
Submit your application. CAS reviews your organisation's scope, personnel, sites, and activities to prepare a detailed audit time calculation and formal commercial proposal.
2
Stage 1 — Document Review
On-site or remote review of your management system documentation, readiness assessment, and confirmation of Stage 2 audit scope and plan.
3
Stage 2 — On-site Audit
Full on-site audit of the implemented management system against the standard's requirements. Findings are reported; nonconformities must be closed before certification.
4
Certification Decision
CAS's independent certification committee reviews the audit findings and issues the certificate. The certificate is valid for 3 years.
5
Surveillance & Recertification
Annual surveillance audits (~1/3 of initial audit time) maintain certification. Recertification audit (~2/3 of initial time) is conducted before certificate expiry to renew for a further 3 years.
Audit Time: ISO 45001 audits include mandatory on-site shift coverage. Per IAF MD 5:2023, at least one shift inside and one outside regular hours must be audited in the first certification cycle.
Frequently Asked Questions
Yes. ISO 45001 explicitly requires organisations to manage OH&S risks from contractors and subcontractors performing work under the organisation's control.
Partially. Per IAF MD 5:2023, process control and OH&S risk control cannot be audited remotely — on-site auditing remains mandatory for these elements.
ISO 45001:2018 fully replaces OHSAS 18001. All OHSAS 18001 certificates have expired. CAS supports transition and upgrade audits.
