Abstract: In order to solve the problem that relevant concepts of safety risk classification control are not unified and confusion used in actual work safety, the connotation and definition of six basic concepts, including hazard, accident potential, cause of the accident, accident category, hazardous and harmful factors and safety risk, were summarized and clarified based on comparative analysis of relevant domestic standards and scholars' opinions. Then the interrelationship between concepts was discussed and the conceptual relationship diagram of safety risk classification control was proposed. Finally, based on basic concepts and safety management, a full-time safety risk control model based on key time points was established which clarified relationships between safety risk management and accident potential investigation and control, accident prevention and emergency response. The accident control system of "5E" countermeasures was constructed which clarified the relationship between accident prevention, risk assessment and emergency management. The results show that basic concepts are the basis of safety risk classification management and control, and that the relationship among safety risk management and control, accident potential investigation and control, accident prevention, risk assessment and emergency response is related to the implementation effect of safety risk classification control, which should be clarified and standardized.

Key words: hazard, accident potential, hazardous and harmful factors, safety risk control, accident potential investigation and treatment, accident prevention, emergency
