ISO 45001:2018 is a globally recognized certification that sets the benchmark for occupational health and safety (OH&S) management systems. Applicable to organizations of all sizes and types, it emphasizes the importance of creating a safe and healthy work environment. This standard not only focuses on the organization itself but also considers the broader supply chain, ensuring that contractors, suppliers, and other external workers are included in its safety management scope.

Key Features

  • Provides a framework for OH&S management systems to prevent work-related injuries and illnesses.
  • Integrates other aspects of health and safety, such as worker wellness and well-being.
  • Addresses various factors that might result in illness, injury, or even death.


To achieve this certification, organizations undergo a rigorous two-stage audit process, evaluating workplace conditions, practices, and hazard identification. ISO does not issue certifications or conduct conformity assessments. Instead, ISO certified third-party entities, carry out ISO audits. These external auditors evaluate businesses and their operations to ensure compliance with standards and an unbiased assessment.

Duration and Renewal

The certification remains valid for three years, subject to yearly partial audits to ensure ongoing compliance. At the end of this term, organizations can undergo a comprehensive audit process for recertification, which is more detailed than interim annual audits. Furthermore, to ensure its global relevance, ISO standards, including ISO 45001, undergo a systematic review every five years.

Impact and Significance

ISO 45001:2018 enables organizations to provide safer workplaces, reducing risks and enhancing overall health and well-being. It covers various aspects, from ensuring the availability of necessary work equipment to establishing emergency protocols and managing incidents. The standard aims to involve top management in ensuring a safe and healthy environment for both employees and visitors.
