摘　　要：基于液氯储运过程中的安全现状分析和事故统计,结合挪威船级社的定量风险分析软件SAFETI(Software forAssessment of Flammable,Explosive and Toxic Impacts),分析了氯气的危险特性以及液氯储运过程中因泄漏而导致的毒害危险性,归纳出了液氯储运过程中可能发生的各种泄漏事故类型;并运用SAFETI软件对某液氯槽车发生泄漏后的毒性危害后果及风险进行定量评价,建立具针对性的评价模型,模拟预测事故后果及风险,取得了液氯泄漏毒害事故危害程度和范围及造成的个人风险和社会风险的计算机模拟图表及报告等,对预测、预防液氯泄漏毒害事故以及减少事故造成的人员伤亡和财产损失具有工程应用价值.Based on the analysis of safety status and the statistic of accidents in the storage and transportation of liquefied chlorine, the hazard characteristics of chlorine and the poison fatalness caused by the leakage in the storage and transportation of liquefied chlorine are analyzed, with the quantitative risk-analyzing software SAFETI （ Software for Assessment of Flammable, Explosive and Toxic Impacts） in the DNV being adopted. Then, the types of leakage accidents that may happen in the storage and transportation of liquefied chlorine are summed up, and a quantitative assessment for the toxic consequence and risk in a liquefied chlorine tanker leakage is carried out using SAFETI, with the relevant assessment models being established. By the proposed models, the consequences and risks of accidents are forecasted and simulated, and the hazard degree and rang, as well as the individual risk and societal risk caused by the accidents are simulated in the form of graphs and reports, which helps forecast and prevent leakage accidents in practice and helps reduce personnel casualty and property loss.
