Safety Management Plan through Offsite Risk Assessment during Tank Terminal Construction

Objectives : In order to conduct the quantitative risk assessment for hazardous chemical storage facilities at the tank terminal in the port area, the entire risk assessment process was performed in according to the guidances of the Korea Ministry of Environment.Methods : The risk of the facility was derived by the worst-case scenario, alternative scenario, and then evaluated by KORA program. The countermeasures of the risk were suggested by the concept of LOPA.Results and Discussion : Focusing on the worst case scenario and alternative scenario among the scenario having effet to offsite, risk can be reduced to satisfy regulation by applying measures of passive, active, and managerial.Conclusions : According to the result of risk assessment on benzene storage tank and tank lorry when port construction, the amount of storage inside the tank has a significant impact on the offsite. It is necessary to organize the risk of benzene, and comprehensive management of tank terminal storage facilities.
