Study On Safety Risk Assessment And Early Warningof Chemical Enterprises In B City

With the development of social and economic transformation in the new period,our country safety accident frequency fell steadily throughout,in total have decreased significantly,but the major workplace accidents still happen and exist hidden dangers,and chemical industry as a complex hazards,high-risk technical personnel are gathering places,has become the main base to prevent and contain the social risks.Based on the chemical enterprise safety production risk analysis of the key factors and the cause of typical safety accident category,with major hazards identification as the breakthrough point,the safety in production as the ultimate goal,and connecting with the actual sampling survey data and 5 mle analysis,in accordance with the "man,machine,material,method,ring,pipe" thinking mode,building B,the chemical enterprise safety risk assessment index system.At the same time,the cooperative game model is used to calculate the combined weights by using multiple methods of weight calculation.The framework of enterprise risk classification is determined by using system analysis method and expert scoring comparison for reference,and the classification model is verified by sample survey data.The overall analysis according to the classification standard can reflect the actual production and operation of the industry to a certain extent.In the risk assessment index system frame based on calculation results and risk value,reference percentile sorting method B,chemical enterprise safety risk early warning model is established,using the example of comprehensive early warning index,the quantitative analysis and numerical reflect intuitive,carried out in accordance with the set alarm limit the overall division,can effectively simulate the area chemical enterprise production safety risk.Finally,according to the problems reflected by data calculation and sampling survey,relevant Suggestions and opinions are put forward for different subjects,which is of guiding significance for augmented reality.
