The fire and explosion index method developed by Dow Chemical Company was employed to analyze and assess the hazard associated with the VDF storage tank unit.Quantitative evaluation of the fire and explosion risk index for the VDF storage tank unit was conducted both before and after implementing safety compensation measures.The results revealed that prior to implementing safety compensation measures,the danger level of the VDF storage tank unit was classified as Ⅴ,whereas it decreased to a level of Ⅱ following implementation of these measures.According to the safety compensation index system of Dow Chemical,a projection pursuit evaluation model based on genetic algorithm was established,including 24 evaluation indexes from 3 dimensions of process,material isolation and fire control,and the corresponding evaluation criteria were formulated.The research results show that computer control,other process risk analysis,standard operating procedures(SOP)and other indicators have a great impact on the target layer.Based on the evaluation results,several suggestions are put forward to improve the unit safety level.
