Fault Tree Analysis of the Storage Tanks in the Chemical Industry

Storage tanks of chemical industry often reserve many hazardous substances, the fire, explosion and leakage accident of them often leads to great damage to property and casualty. Fault tree analysis is an important method for safety analysis, it has many advantages on the chemical industry storage tank analysis. This paper studies the features of chemical tanks and the fault tree method, analysis the harmful factors of the tanks systematically. Then take an fire and explosion accident of tank for example to analysis, including: draws fault tree, sets quantitative analysis, calculate the probability and critical importance degree, propose appropriate measures for accident prevention. Finally summarized the advantages of the fault tree analysis in safety analysis of the chemical industry tanks, and the need for improvement.
