ISO 45001 2-Stage Registration Audit

ISO 45001 requires a 2-stage registration audit to become a certified organization. The registration process can be a bit confusing, especially with the various audits and interchangeable language. The 2 stage registration audit is an external audit performed by a third party.  If both Stage 1 and Stage 2 audits are successful, then an organization will be certified to ISO 45001. The goal of a Stage 1 Audit is to determine an organization’s preparedness for their Stage 2 Certification Audit. The Stage 2 Audit assesses the implementation and success of the organization’s ISO 45001 management system.

Stage 1 (Readiness Review) Audit:

The Stage 1 Readiness Review, as the name states, is the first stage in the certification audit process. Its goal is to determine if the organization is able to move on to the Stage 2 Certification Audit. During stage 1 the registrar will review the requirements of the management system, including: documented information, evaluate the client’s site specific conditions, and talk to personnel. The auditor will review the organization’s scope and gather information on the processes and operations, equipment, levels of control, and any statutory or regulatory requirements. The auditor is looking to make sure that objectives are being met and key performance indicators, or occupational and safety aspects, are defined and understood. Both internal audits and management reviews will be evaluated to make sure they are being performed adequately along with the implementation of the management system to determine if the organization is ready to move forward with the Stage 2 Certification Audit.

The documented expectations of the Stage 1 Audit are: 

  1.   Organization’s OH&S scope (4.3)   
  2.   OH&S policy and objectives (5.2)
  3.   Roles and responsibility (5.3)

Worker involvement  

  1.   Planning for OH&S objectives (6.2.2)
  2.   Legal and other requirements (6.2.2) 
  3.   Inventory of risks and hazards (6.1.1 &

Other areas that may be monitored are context of the organization (4.1) and interested parties (4.2).

A Stage 1 Audit usually takes place in one or two days. This audit is almost always onsite, but when an organization has more than one location the audit may occur at their head office. After the Stage 1 audit is complete, planning for Stage 2 may begin. This includes reviewing the allocation of resources and details for the next phase of the audit. Documented information will be given to the organization to allow them to fix any nonconformances that may arise in the final audit.

Stage 2 (Certification) Audit:

The purpose of the Stage 2 Audit is to confirm a company’s occupational health and safety management system is fully compliant with ISO 45001:2018. One to two months following the Stage 1 audit, the certification body will return to audit your entire OHSMS. The CB will analyze each process within your organization for compliance with ISO 45001. This includes such things as customer requirements, and legal and organizational requirements. The length of the Stage 2 audit is determined by the size of the organization, number of sites, and the functions included within the system.

The Stage 2 Audit will include:

  • Evaluating the documented information to ensure that the management system conforms with all standard requirements
  • Report how well the occupational health and safety management system complies with the organization’s occupational health and safety manual and procedures
  • Evaluation of internal audits, management review and management responsibility for the organization’s policies
  • Report all nonconformances so that they can be assessed further.
  • Create the surveillance plan for the organization and choose dates for the first surveillance visit in the following months.

If the Certification Body does not discover any serious nonconformances, the organization’s management system(s) will be certified.

Surveillance Audits

The Certification Body performs surveillance audits once per year during the issued certificate validity. Surveillance audits are performed and documented in an analogical way like the certification audit. Lead auditors shall elaborate the surveillance audit report within 14 days from the realization of surveillance audit.

Transfer of accredited certification

Transfer of accredited certification means appreciation of existing and valid management system certificate awarded by other accredited certification body for the purposes of certificate.
