Safety assessment of gas lines crossings under railways

Abstract

The article provides an assessment of safety of train passengers when implementing accident scenarios related to depressurization of main gas line at a railway crossing. The analysis of the assessment results for the number of victims including those killed among train passengers obtained by the methodology in the industry regulatory documents has been made. This analysis of the assessment results for social risk of death of train passengers has revealed some sections of gas lines, which do not comply with the requirements of regulatory documents without additional safety measures. Some technical solutions have been proposed to reduce the risk of passenger death.
