For organizations operating in the UK
BS OHSAS 18001:2007 Occupational health and safety management systems. Requirements specifies requirement for an occupational health and safety (OH&S) management system, to enable an organization to control its OH&S risks and improve its performance.
It does not state specific OH&S performance criteria, nor does it give detailed specifications for the design of a management system, which is given in BS 8800:2004. BS OHSAS 18001:2007 is the UK implementation of OHSAS and has the status of a British Standard.
BS OHSAS 18001:2007 implements, as a British Standard, OHSAS 18001:2007, which supersedes OHSAS 18001:1999 but remains current until 01 July 2009.
There have been a number of significant changes to the standard since the first edition was published in 1999.
The changes reflect the widespread use and experience of the standard in more than 80 countries, and by approximately 16,000 certified organizations
Principal amongst the changes are much greater emphasis on "health" rather than just "safety", and significantly improved alignment to BS EN ISO 14001:2004 (to enable organizations to develop "integrated management systems").
