The occupational safety and health management system should first aim at implementing the OHS policy of enterprises, and then ensure that this policy can be effectively implemented. It is not only organically combined with the overall management function of the enterprise, but also a dynamic self-adjustment and perfect management system, involving all activities of OHS. It requires the planning, organization, implementation, inspection, monitoring and other activities in OHS management of enterprises to be centralized, summarized and decomposed, and transformed into corresponding documented objectives, procedures and operation documents.
