Recently, the Security Committee of the State Council issued an urgent notice calling for the earnest implementation of General Secretary Xi Jinping's directive spirit on Jiangsu Xiangshui Tianjiayi Chemical Co., Ltd. & ldquo; 3 & middot; 21 & rdquo; especially major accidents, and the deployment of further improving current work safety and resolutely preventing and curbing major and extraordinary accidents. The notification requires risk assessment of all chemical industrial parks to eliminate major potential hazards in a timely manner.
Yang Ting, secretary-general of the CPCI Park Working Committee, said that the safety risk assessment of the chemical industry park is mainly based on the current situation assessment of the chemical industry park, taking into account the future development planning. Safety evaluation units should fully identify existing or potential dangerous and harmful factors, conduct qualitative and quantitative analysis, confirm the controlled degree of safety risks, and put forward suggestions for safety production and environmental safety of chemical industry parks on the basis of comprehensive understanding of the overall development plan, industrial positioning and development status of chemical industry parks, mastering the overall layout of chemical industry parks, enterprise distribution and surrounding environment. Measures to prevent accidents, control risks, reduce accident losses and impacts.
It is reported that China has long required safety risk assessment of chemical industry parks, including:
The general situation of economic and social development is the comprehensive economy, economic structure, industrial structure, regional location, resources, population and medical condition of the area where the chemical industry park is located; the surrounding environment, the distribution of residential areas, schools, markets, hospitals and other personnel-intensive places and key facilities within 5 km of the chemical industry park, and the distribution of the permanent residents in the concentrated area; That is, the geographical location and natural conditions of the chemical industry park; the planning situation, including the overall planning, industrial positioning and industrial characteristics of the chemical industry park, land use planning and enterprise distribution; the basic situation of the chemical industry enterprises, including the name, location and area of the chemical industry enterprises in the chemical industry park, the connection of upstream and downstream products among enterprises, the concentration of non-chemical enterprises and civil enterprises in the chemical industry park. Distribution of facilities, distribution of major hazard sources of hazardous chemicals, enterprises involved in major hazard sources in chemical park and their distribution, grade and monitoring measures of major hazard sources, centralized monitoring of major hazard sources in chemical park, emergency rescue preparedness, production safety accident records, including general analysis of hazardous chemical accidents and other accidents in chemical park in recent five years, etc. Transportation, including hazardous chemicals transportation pipelines in chemical parks, enterprises engaged in hazardous chemicals transportation in chemical parks and their vehicles and employees, as well as hazardous chemicals transportation routes and the types, quantities and flows of major hazardous chemicals transported in chemical parks; current situation and planning of public supporting facilities; current situation of safety production management, etc. Aspect.
In the evaluation, emphasis is laid on five aspects.
One is the safety risk assessment of Chemical Park location. Mainly from the industrial orientation, industrial structure, nature and development direction of chemical industry enterprises in the chemical industry park, this paper analyses whether the construction of chemical industry park is consistent with the requirements of economic and social development planning and industrial development planning in the region, evaluates the possible impact of chemical industry park on the safety of personnel-intensive sites, important facilities and environmentally sensitive targets around the chemical industry park, and identifies the surrounding environment of the chemical industry park. The influence of natural conditions on the safety production of chemical industry parks is discussed, and the corresponding countermeasures are put forward.
Second, the overall layout of Chemical Industry Park safety risk assessment. Based on the industrial characteristics, division of main functional areas, enterprise distribution, upstream and downstream industrial chains, logistics transportation and natural conditions of chemical industry parks, the shortcomings and unreasonableness of regional planning, general layout planning and land use planning of chemical industry parks are analyzed, and suggestions for layout adjustment are put forward. The industrial selection, restriction (control) type of enterprises to be introduced into the planning and construction zones are proposed. Propose planning proposals for enterprise distribution and logistics transportation.
Thirdly, risk assessment of safety correlation among established enterprises in chemical industry park. Focusing on the enterprises involved in the key supervision of hazardous chemicals, hazardous processes and major hazard sources of hazardous chemicals in chemical industry parks, this paper mainly adopts quantitative analysis method to analyze the possible interaction of fire, explosion, poisoning and other accidents on adjacent enterprises and regions, to analyze the possibility of causing serial accidents, and to determine individual and social risk values and their risks. Acceptance. At the same time, according to its dangerous characteristics and dangerous degree, the key prevention and control objectives of chemical industry park are determined, and the countermeasures to effectively reduce the overall danger of the region are put forward.
Fourthly, risk assessment of public engineering facilities and logistics transportation safety in chemical park. Focusing on the safety and conformity of municipal and public engineering facilities in chemical industry park, the problems and shortcomings of water supply, power supply, heating, gas supply, communication, sewage treatment, solid waste treatment, wharf, railway, hazardous chemicals pipeline, public pipe corridor and road transportation are analyzed, and corresponding improvement measures are put forward.
Fifth, the assessment of safety management and emergency response capability of chemical industry park. According to the development plan, existing scale and industrial characteristics of chemical industry park, this paper analyses the matching between the establishment of safety management organization and the allocation of safety management personnel, the effectiveness of safety management measures and implementation, evaluates the establishment and operation of emergency rescue plan, emergency material reserve, emergency rescue team and rapid emergency response mechanism in chemical industry park, and analyses chemical industry park. The existing problems and deficiencies in safety management and emergency management in the district are put forward, and suggestions and measures for improvement and strengthening are put forward.
Yang Ting emphasized that the risk assessment of chemical industry park is a dynamic analysis process based on the point, line and area risks of enterprises in the park, not a once-and-for-all work. The key of chemical industry park is to establish a dynamic management and control system based on risk assessment, so that the risk of the park can be dynamically assessed regularly according to the change of risk sources in the chemical industry park, and based on risk. Dynamic evaluation results are used to establish dynamic and accurate safety inspection plan, hidden danger investigation plan, emergency drill plan, safety supervision, emergency management and other work, so as to truly establish a risk-based dynamic management and control system of chemical industry park.
