The dual prevention mechanism is to construct two firewalls to prevent production safety accidents. The first is to manage the risk, through the qualitative and quantitative methods to the risk of numerical expression, and according to the level from high to low in order to divide into major risk, large risk, general risk and low risk, so that enterprises combined with the size of the risk of reasonable deployment of resources, hierarchical hierarchical management and control of the different levels of risk.
The second course is to cure the hidden danger, investigate the lack, loopholes and risk control failure links in the process of risk control, rectify these failure links, and dynamically control the risk. Safety risk classification and control and hidden trouble investigation and management **** with the construction of a dual mechanism to prevent accidents, constituting two protective barriers, effectively curbing the occurrence of serious accidents.
