The OHSAS 18001 occupational health and safety (OH&S) management systems standard provides your organization with a structured framework that can help meet your OH&S legal and policy requirements, control your OH&S risks, minimize workplace-related injuries and illnesses, continually improve overall OH&S performance and demonstrate conformity to the requirements of the standard.

The OHSAS 18001 standard is compatible with other management systems standards such as ISO 9001 and ISO 14001 and can be easily integrated with existing quality, environmental or other management systems to obtain process efficiencies.

Benefits of Certification

The benefits of a well implemented, independently audited OHSAS program include:

  • Increased awareness of OH&S hazards, risks and control measures at all levels resulting in improved conformity to requirements
  • Improved risk management through clear identification of hazards and mitigation of potential risks through planned monitoring, measurement and control measures
  • Demonstrated commitment to safeguarding the health and safety of employees, contractors, customers and others in the workplace, with the potential for improved reputation within the community and stronger stakeholder relationships
  • Reduced costs resulting from decreased down-time from fewer injuries and illnesses, and reduced legal fees, penalties, workplace insurance premiums and worker compensation costs
  • Potential for increased business opportunities with the added credibility of independent third-party certification

Certification Process

The NSF-ISR OHSAS management systems certification process involves these steps:

  1. Application, Proposal and Contract
    Your company submits an application, NSF-ISR makes a proposal and you sign a contract (master agreement).
  2. Audit Team Assignment
    NSF-ISR assigns an audit team.
  3. Documentation Review
    We perform a document review for the management system and issue a report of conformance or nonconformance. (This is usually done in conjunction with the Stage 1 audit but may also be done separately.)
  4. Stage 1 Audit (On-Site Readiness Review)
    We review the level of implementation of your core OH&S management system requirements and verify the readiness of the system to undergo the Stage 2 audit.
  5. Stage 2 Audit (Certification Audit)
    Our audit team conducts a comprehensive on-site audit to verify conformity to the OHSAS 18001 or other OH&S management systems standard.
  6. Independent Internal Review
    An NSF-ISR certification board reviewer verifies that all components of the certification process were performed as per procedures, that the audit covered all the requirements of the standard and that the report and associated documentation accurately reflect the level of implementation based on the recorded observations, before making the final certification/recertification decision.
  7. Notification of Registration
    We notify your organization in writing, issue the certificate and publish the certification in our online listings.
  8. Surveillance Audits
    NSF-ISR performs semiannual or annual surveillance audits to verify that the management system is maintained and continues to meet requirements.
  9. Reassessment
    NSF-ISR performs a reassessment audit every third year in accordance with requirements.
