摘　　要：液氯在运输和储存过程中存在泄漏的危险性,一旦发生泄漏可能导致包括人员中毒、死亡和环境破坏等一系列灾害的发生。本文针对上述各种灾害的具体发生条件及其危险性进行了分析,提出运用事故情景分析对液氯泄漏进行定量风险评价,识别具有最高风险的事故情景,并对一典型场所进行详细的后果分析,得出半数致死浓度(LC50)的危害半径。The liquefied chlorine has risk associated with leak in the traffic and storage process. The leak of liquefied chlorine can induce disasters including poisoning, death and environmental disruption, etc. In this paper, occurring condition and risk of those disasters were analyzed. A method using accident scenarios analysis for the quantitative risk assessment on liquefied chlorine was developed, and the highest-risk scenarios were identified. It was processed for detail consequence analysis in a typical scene, and the damage radius of median lethal concentration（LC50） was calulated.
