Q: Does ISO 45001 involve certification?

Yes, organizations can get certified to ISO 45001 by third-party certification bodies. Certification validates that an organization has implemented the standard properly and has a compliant OH&S management system in place. However, companies implementing ISO 45001 can choose whether they want to go through a certification process or not. As with other ISO management system standards, some organizations choose to implement the standard in order to benefit from the best practice it contains, while others also want to get certified to reassure customers and clients. Many certification bodies are accredited, which means that an accreditation body has provided independent confirmation of their competence. This may bring an additional layer of confidence for stakeholders.
