Study On The Evolution Law And Prevention And Control Measures Of Major Chemical Accidents In Cities

City is a complex with highly concentrated political,economic,cultural,technological,and educational activities.In recent years,China's old political,social and economic structure has undergone tremendous changes,the speed of urbanization has gradually accelerated,and the nature of society is also undergoing transformation.These changes have brought a series of contradictions and conflicts.The urban disaster prevention and resistance ability is relatively backward.The occurrence of urbanization accidents has a direct impact on the city as a whole,which will not only cause casualties,but also cause casualties Economic loss will also affect the living order of urban residents,endanger their mental health,and reduce their sense of security.This is extremely unfavorable for the construction of safe city and safe China.The development law of urban chemical accidents is related to how to deal with and establish the prevention and control system,which is related to the economic development and the construction of a stable and harmonious society.This article mainly uses the literature research method to read a large number of materials and literature to understand the current status and development direction of urban chemical accident research at home and abroad.Starting from related theories,analyze the nature and characteristics of major urban chemical accidents.By analyzing the safety status of urban chemical industry and the causes of major urban chemical accidents,finding out the coupling relationship of risk factors during the occurrence and development of accidents,in-depth analysis of the development and evolution of major urban chemical accidents,and discovering the overall impact of major urban chemical accidents on the city through case analysis Hazards,it has been discovered that urban chemical companies have deficiencies and weaknesses from top to bottom,including the neglect of safety culture training,oversight of potential safety hazards,and lack of emergency response capabilities.Based on the analysis of the causes of major chemical accidents in the city,the law of development and evolution,and the response to accidents,measures to prevent accidents and control the development and evolution of accidents are proposed from the perspective of the government,enterprises,media,and the public,including the soundness of various laws and regulations Measures such as strengthening of supervision and inspection,strengthening of safety culture construction,and strengthening the timeliness of response after accidents,etc.,to build a major chemical industry in the city The accident prevention and control system can effectively prevent the occurrence of urban major chemical accidents,reduce the loss and impact of urban major chemical accidents,create a favorable social environment for the safe development of urban chemical enterprises,enhance the competitiveness of urban chemical enterprises,realize emergency management,and create a harmonious and stable urban public safety environment.
