Study on the Identification, Risk Evaluation and Control of the Dangerous and Harmful Factors of Power Enterprise Database

As an important part of the energy industry, power generation enterprises have complex production process and environment, and many hazard risk factors. The importance of its safety management has gradually become a consensus. Compared with traditional safety management methods, risk pre control emphasizes the planning of prevention and control in advance. Its theoretical basis is to comprehensively and systematically identify and evaluate all hazards and harmful factors. In order to determine the main risk sources and harmful factors, clarify the management focus and direction, formulate more targeted and advanced management measures, prevent the development of hidden dangers and accidents caused by improper risk control, and realize intrinsic safety. “4M ” mainly comes from the theory of “safety management of human, machine, media and 4m elements” put forward by Japanese scholar Shigeru nishima. Under the guidance of 4m barrier theory, power enterprises have formed a set of risk pre control models for identifying, evaluating and formulating measures, and established “operation activity risk”, “maintenance operation activity risk” and “regional environmental risk”, “Equipment”, “failure risk” and “management risk” are five standard basic risk databases. The standard basic risk database identifies hazards, hazards and eco-environmental factors, comprehensively analyzes and evaluates hazard consequences, occurrence possibility, hazard degree and accident type, and puts forward corresponding control measures and behavior standards.
