Workforce health and safety continues to be a challenge worldwide. Over 370 million accidents occur on the job annually and over 2.78 million people die each year as a result of work-related activities.

An occupational health and safety (OH&S) management systems standard provides your organization with a structured framework that can help foster a safe and healthy work environment, minimize workplace-related injuries and illnesses, meet your OH&S legal and policy requirements, control your OH&S risks and continually improve overall OH&S performance.

ISO 45001:2018 is the new ISO occupational health and safety standard which will take the place of the current standard, OHSAS 18001, in spring 2018. Once ISO 45001 is published, companies certified to OHSAS 18001 have three years to migrate their certification to ISO 45001.

Whether you are seeking new certification or wish to upgrade to ISO 45001, our team of seasoned professionals can add value to your business.

Benefits of Certification

By adopting ISO 45001:2018 an organization is able to:

  • Improve worker health and safety
  • Reduce long- and short-term social and economic costs associated with health issues and lost work days
  • Improve worker and customer satisfaction
  • Demonstrate corporate responsibility and meet supply chain requirements
  • Protect brand reputation
  • Improve risk management through clear identification of hazards and mitigation of potential risks through planned monitoring, measurement and control measures
  • Potentially increase business opportunities with the added credibility of independent third-party certification

Certification to international standards establishes credibility and demonstrates your product or service meets customer expectations. In some sectors or industries, third-party independent certification is a legal or contractual requirement.

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 45001 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 Certification
    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.

ISO 45001:2018 Migration

As of March 2018, ISO 45001 is the new international standard for occupational health and safety (OH&S), providing a framework for managing the prevention of death, work-related injury and ill health, with the intended outcome of improving and providing a safe and healthy workplace for workers and persons under an organization’s control.

ISO 45001:2018, Occupational health and safety management systems takes into account other international standards in this area, such as OHSAS 18001, which ISO 45001 replaces. The standard is intended to help organizations, regardless of size or industry, in designing systems to proactively prevent injury and ill health.

In order to help organizations understand the new standard, NSF-ISR has developed resources to simplify the process:
