Abstract:

Based on the analysis of safety status and the statistic of accidents in the storage and transportation of lique-fled 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 leak-age accidents in practice and helps reduce personnel casualty and property loss.

Key words: liquefied chlorine leakage, toxic hazard, quantitative assessment model, SAFETI, individual risk, so-cietal risk
