ISO 45001 is an international standard for health and safety at work developed by national and international standards committees independent of government. Introduced in March 2018, it’s replacing the current standard (BS OHSAS 18001) which will be withdrawn. ISO 45001:2018 specifies requirements for an occupational health and safety (OH&S) management system, and gives guidance for its use, to enable organizations to provide safe and healthy workplaces by preventing work-related injury and ill health, as well as by proactively improving its OH&S performance.
