Standard owner:

BSI British Standards Institution


What does the standard OHSAS 18001 cover?

The standard OHSAS 18001 defines the requirements for a certifiable occupational health and safety (OH&S) management system of an organisation. These requirements include, but are not limited to:

  • The organisation has established a suitable occupational health and safety management system, including mechanisms for organising occupational health and safety in the company, assessment of hazards and risks in occupational health and safety, self-assessment of occupational health and safety performance, identification and control of preventive and corrective action in occupational health and safety, and continuous improvement of occupational health and safety services.
  • The organisation analyses and considers the occupational health and safety requirements of its customers and the requirements of the applicable codes and standards.
  • The certified organisation defines the processes, roles and responsibilities required to ensure occupational health and safety, and ensures regular surveillance to meet the specific requirements of the standard, legal requirements, and requirements of the German Institutions for Statutory Accident Insurance and Prevention, as well as customer- and industry-specific occupational health and safety requirements.

  • What does “certification” and/or the issue of a certification mark for OHSAS 18001 by TÜV SÜD Management Service GmbH mean?
    • The customer has submitted to voluntary assessment (audit) according to defined criteria (certification standard).
    • A certificate and/or the authorisation to use a certification mark is only issued if the assessment (audit) does not reveal any major nonconformities with the requirements of the certification standard.
    • The certificates and/or certification marks are valid for a restricted period of time. Interested parties can check the validity of individual certificates in the certificate database of TÜV SÜD Management Service GmbH.
    • To maintain certificate validity, the certificate holder must annually complete an announced audit with a positive result.
    • Unannounced audits are possible in specific cases.
  • How do we audit?

    Independent and qualified experts (auditors) apply the following auditing techniques:

    • Document review:
      Evaluation of the organisation's provisions and/or documentation to ensure compliance with all occupational health and safety requirements according to the standard and other requirements (particularly legal requirements).

    • On-site-audit
      Verification that the above requirements are effectively implemented in practice in the form of interviews and on-site inspection at the customer's premises. Random checks on site of processes and situations on the basis of records, such as the availability of documentation of hazard assessment, job and role profiles, induction and instruction records, test reports, inspection and audit reports, minutes of meetings, training and qualification certificates, investigation reports of accidents, near-misses and unsafe situations, documentation of defined objectives and the resulting improvement projects.
  • What is beyond the scope of certification according to OHSAS 18001?
    • Certification according to OHSAS 18001 does not constitute product certification. Certification thus does not provide any direct statements on the safety of a product or service of the certified customer. Certification according to OHSAS 18001 does not mean that the company manufactures products or provides services of higher quality.
    • Certification according to OHSAS 18001 does not ensure in each specific case that all relevant statutory, regulatory or other - e.g. industry or customer specific - occupational health and safety requirements are met, even though this is one of the key objectives of the occupational health and safety management system.
