ISO & OHSAS

ISO and OHSAS Certified Management Systems

The International Organization for Standardization (ISO) and the Occupational Health and Safety Assessment Series (OHSAS) Project Group have created environmental, health and safety management system (EHS) standards.

ISO and OHSAS Management Systems

The International Organization for Standardization (ISO) and the Occupational Health and Safety Assessment Series (OHSAS). Project Group have created environmental, health and safety management system (EHS) standards for facilities seeking to improve their EHS performance.
Organizations may obtain ISO or OHSAS certification demonstrating that their EHS management systems meet third-party standards.

Important provisions of ISO and OHSAS management systems

Both ISO and OHSAS management system standards create a framework for organizations to create their own management systems.
ISO and OHSAS do not set specific EHS performance criteria as a requirement for certification.

Instead, the management systems create a culture in which organizations set their own standards, monitor their EHS performance, and then improve their performance after reviewing and evaluating their performance.

Why implement an ISO or OHSAS management system?

Implementing an ISO- or OHSAS-certified EHS management system can:

  • Reduce costs
  • Increase EHS performance
  • Mitigate the potential for environmental, health and safety incidents
  • Boost your corporate image

Because ISO- or OHSAS- certified management systems are generally verified by third-parties, customers, regulators, and the public can be assured that you value your environmental and occupational health and safety responsibilities.

ISO- and OHSAS- certified management systems are also important because the EHS regulatory landscape is frequently changing. By deploying a management system, you can systematically track regulatory development and ensure that your organization stays on top of regulatory changes and avoids penalties, negative publicity, litigation, and lost productivity.

Importance of implementing a regulatory watch on ISO and OHSAS standards

ISO and OHSAS revise their standards over time to improve and clarify the requirements. Additionally, ISO is drafting an occupational health and safety management system standard, ISO 45001, which is intended to replace OHSAS 18001.

OHSAS intends to withdraw its standard, if ISO 45001 satisfies OHSAS’ criteria. ISO 14001 is currently under review as well.
