DOW火灾爆炸指数评价法在油库中的应用

为了客观地评价油库的安全性，采用DOW(道)化学公司火灾爆炸指数评价法来确定物质、设备及工艺装置等存在的潜在危险性，定量计算火灾爆炸可能导致的危害程度和停产损失，是一种有效的手段。介绍了DOW火灾爆炸指数评价法的原理、评价程序及计算步骤。该评价法是一种识别和筛选油库重大危险源的有效工具，可为更深层次的油库安全评价定量分析提供可靠的依据。

Application of Method of Evaluation of DOW's Index of Fire Explosion in a Oil Tank Farm

In order to evaluate objectively the safety of a oil tank farm, a method fo r evaluating the DOW's Index of fire explosion is put forward and its principle and evaluation procedure are discussed. It can quantitatively calculate the extent of risk and economic loss due to the accidents. Thus lar ge vessels in a oil tank farm are evaluated reasonably,also,it can provide a scientific basis for prediction o f fire of oil tank farm and daily management of a oil tank farm. Moreover,it is found that the method is available to screen hazard sources in order to make preparation for the deeply quantitative analysis of safety eval uation of oil tank farm. In this paper,the principle of risk assessment is discussed theoretically.
