Research And Implementation Of Dynamic Monitoring System For Oil Tank Area Major Hazard Installations Based On The GIS

Oil products is a kind of hazardous and combustible materials with the properties of flammable and explosive, volatile, highly flowable, thermally expansive, easily electrostatic and toxic. Almost oil tank area is the major hazard installations and is also the important supervision object of work safety. By integration of safety supervision features such as risk assessment, monitoring and warning, safety management and emergency rescue, a major hazard dynamic monitoring system has been developed to provide service and support for scientific management and continuous improvement of work safety, which integrates data acquisition, analysis, expression together.The paper has analyzed the risk factors for physicochemical properties of chemical materials, tanks, managerial personnel and operating personnel, as well as the cause and the kinds of the accidents happened in tank area. Based on harmful hazard analysis, a security monitoring system based on geographic information system(GIS) for oil tank was developed by optimizing the accident consequence model and the quantitative risk assessment method. In this system, the GIS spatial analysis technology was firstly adopted to accomplish the geographic elements datumization of tank area, with mathematical models such as heavy accident result simulation Analysis, Personal Risk Calculation,as well as AHP-Fuzzy Comprehensive Evaluation applied, the system can achieve many security management and emergency decision functions. The project application had shown that the system did well in monitoring and pre-warning, evaluation of safety class, heavy accident result simulation analysis and decision-making of emergency rescue for tank area.
