N2  - Although safety accidents such as suicides and falls have disappeared since screen doors were installed to prevent safety accidents involving passengers falling onto tracks or colliding with trains, another safety accident has occurred owing frequent failures of screen doors. To prevent and mitigate these accidents, failure data for screen doors (2016-2018) operated on Korean urban railway platforms were divided into 8 categories and 36 types of failures. This study presents the importance of breakdowns by evaluating the severity with Failure Modes and Effects Analysis (FMEA) using the data derived earlier, and established preventive measures and countermeasures against failure using the Bow-tie methodology. For the Bow-tie methodology, preventive measures are established to remove and mitigate causes of failure in accordance with ALARP(As Low As Reasonably Practicable) for hazards so that the screen doors could operate safely. The results of the analysis in this study will be contributed to improve maintenance work, prevent safety accidents, and improve safely of screen doors. © 2020 The Korean Society for Railway.
