Research On Inherent Safety Analysis And Improvement On Tiger Beach Liquefied Petroleum Gas Station

Liquefied petroleum gas station is a high fire risk area in the city,in the event of fire explosion accident will cause casualties and property losses.At present,the research of liquefied petroleum gas station safety assessment is less,a widely recognised of methods and standards is lack.In order to ensure the healthy development of the liquefied petroleum gas stations in our country,reduce serious consequences of fire accident,in this paper,through research on the influence factors of affect liquefied petroleum gas station safty,build safety assessment system of liquefied petroleum gas station,adopt safety engineering technology for evaluation,used in Tiger Beach liquid gas station safety assessment,it has very realistic significance for liquefied petroleum gas station safety assessment.This paper make full use at the characteristics that fault tree analysis can easy to find the relationships of all levels,establishing safety assessment system of liquefied petroleum gas station.Combines analytic hierarchy process(ahp)and fault tree analysis method,constructs the first level of liquefied petroleum gas evaluation index system.it is the ignition source,fuel and oxidizer.To avoid the fault tree to solve the complex problem of minimum cut sets and minimization algorithm,to ensure the effectiveness of the liquefied petroleum gas station essential safety evaluation index.Using multilevel extension assessment method to evaluate the security of liquefied petroleum gas station and risk level.Through the evaluation example,this article proposed liquefied petroleum gas station safety assessment methods to liquefied petroleum gas station security level to make objective evaluation,use area to describe the safety degree of the system,and improve the accuracy of the safety evaluation conclusions.According to the results of multi-level extension evaluation,analyzes the key factors of fire risk,puts forward some measures and Suggestions to further improve the level of liquefied petroleum gas station intrinsically security.It has a certain application value for safety assessment work and daily safety management work of liquefied petroleum gas station.
