Background on ISO PC 283 Occupational Health and Safety Management Systems

The International Organization for Standardization (ISO) has developed an international standard setting out requirements for establishing, implementing and maintaining an occupational health and safety management system.  This standard, ISO 45001, Occupational health and safety management systems – Requirements with guidance for use, specifies requirements for organizations to use for implementing a management system to help them in providing a safe and healthy workplace and preventing injury and ill health to their workers.  

ISO 45001 is a specification standard that is intended to be used for third-party certification.  It is anticipated that ISO 45001 will replace OHSAS 18001:2007. 

This standard was developed by ISO Project Committee (PC) 283.  For more information about PC283, click here

The standard development bodies from over  60 countries participating in this standard development effort.  In addition, several Liaison Organizations participated in the development of this standard, including the International Labor Organization (ILO).

Like other ISO management system standard, including ISO 9001 (for quality management systems) and ISO 14001 (for environmental managements systems, ISO 45001 was developed using the high-level structure set out in Annex SL of Part 1 of the ISO Directives so that organizations would be able to merge their management systems.
