Construction Theory and Practical Exploration of the Dual Prevention Mechanism
To clarify the basic theory of the dual prevention mechanism and form a set of practical and effective construction methods and procedures,methods such as literature analysis,qualitative analysis,speculative analysis,and model construc-tion are used to distinguish the key concepts of the dual prevention mechanism(risk points,hazards,risks,and accident hazards),analyze their internal logical relationships,and construct a logical relationship model.On this basis,this study summarizes the general methods and procedures for constructing a dual prevention mechanism.The analysis results show that hazards can be divided into root hazards and state hazards.Threat events are the actual manifestations of potential state haz-ards,and the core of risk control is to prevent potential state hazards from evolving into near miss.In the process of identif-ying hazards,the root hazards and state hazards are subdivided into 2 types and 5 manifestations,respectively,and there should be a one-to-one correspondence between accident hazards and control measures;The construction program of the du-al prevention mechanism is divided into 5 stages,including 16 work contents and 13 output results.
