Risk assessment of anti-explosion safety for group buildings outside the major hazards of hazardous chemicals
In order to accurately and quickly identify the anti-explosion safety risk of the group buildings outside the plant boundary of the major hazards,firstly,based on the urban disaster risk system theory and disaster risk management concept,an anti-explosion safety risk assessment index system of group buildings was established.The four assessment dimensions include explosive hazard,explosive vulnerability,anti-explosion safety capacity and anti-explosion response capacity.Secondly,an anti-explosion safety risk assessment model based on the extension connection cloud is constructed.It eliminates the uncertainty generated by the cross-fertilization of multiple risk information and realizes the quantitative assessment of the anti-explosion safety risk level of group buildings.Finally,in order to verify the effectiveness of the assessment methodology,the assessment process is applied to group buildings outside the major hazards of explosives-type hazardous chemicals in a city.The results show that the method can quickly and effectively assess the level of anti-explosion safety risk of group buildings.The method reliably and intuitively reflects the anti-explosion deficiencies of group buildings.It provides decision-making support for the anti-explosion safety planning and construction of group buildings outside major hazards enterprises.
