Occupational Health and Safety Management System (OHSMS) is a modern safety production management model that emerged internationally in the late 1980s. It is called "management method in the post-industrial era" together with ISO9000 and ISO14000 standard systems. The main reason for the emergence of occupational health and safety management system is the requirement of enterprise development. With the expansion of enterprise scale and the improvement of production intensification, higher requirements are put forward for enterprise quality management and business model. Enterprises must adopt modern management models to make all production and operation activities, including safety production management, scientific, standardized and legal.
