British Standards Institute BS 1996 Occupational Health and Safety Management System Guide, which was issued in 8800 by 8800, is the first health and safety standard to be a guide. However, this standard did not constitute a basis for the certification studies of the organizations. Thereafter, other organizations have issued standards such as occupational health and safety. These standards were basically using BS XNUMX standards, but their content and application were different.

A study was initiated with the participation of independent audit companies and certification bodies to eliminate these differences. The aim is to prepare a health and safety standard that will be accepted internationally. At the end of the work done in 1999 OHSAS 18001 Occupational Health and Safety Management System The standard was uncovered.
