Development of Emergency Response Procedures Based on Scenarios of Urban Railroad Incidents-Focused on Fire Accidents

Abstract

Urban Railroad has been constantly exposed to the risk of accidents because of uncertain system of railroad safety in Korea. The Korea government enacted a law, railroad safety Act, for each railroad operating company to make the Standard Operation Procedures (SOP) to reduce the magnitude of fatality and injury in the case of emergency, including responsibility and obligation. This study, in the beginning, has established emergency response scenarios to build the effective SOP through the analysis of railroad accident's distinguishable remarks. Then, emergency response procedures are developed based on the emergency response scenario. Activity-action diagrams are suggested to make a consecutive procedure for the emergency response. Each activity consists of a bundle of actions by emergency response personnel. Finally, a case study has been performed for a fire accident in tunnel of urban rail transit.
