Development of HAZ-RAM for reducing HAZMAT transportation accident

The accident of HAZMAT causes not only physical damage but also secondary accidents which makes negative effects in regional environment and society. Thus, based on a particular management system in HAZMAT transportation, it is necessary to prevent accidents and to minimize secondary damages. According to the accident data, the causes of accidents are human factor(62.8%), physical factor(9.9%), other factors(23.1%) and unknown factors(4.2%). Especially the most accidents related with human factor are caused by neglect of management and surveillance. In this study to minimize the risk caused by human factor, HT-RAM(Hazmat Transportation Risk Assessment Matrix) was developed using current RAM(Risk Assessment Matrix). For developing HT-RAM effectively, the following 3 factors are also considered. First, the type of HAZMAT accident is defined and classified. Secondly, the severity and the frequency are analyzed by accident type. Finally, the plan for management in transportation was suggested to reduce the risk and accident. In the future, HAZ-RAM developed in this research is applied to the HAZMAT transportation management system, it will reduce not only traffic accident but also the secondary damage caused by the accident.
