The Safety Risk Model (SRM) is a quantitative representation of the potential accidents resulting from the operation and maintenance of the GB rail network. It comprises a total of 120 individual models, each representing a type of hazardous event. A hazardous event is defined as an event or an incident that has the potential to result in injuries or fatalities.
The SRM is, where possible, populated using data from the rail industry’s safety related incident data taken from safety management information system (SMIS). The SRM also includes predictions of the risk contribution from low frequency but potentially high consequence accidents for which there is little or no relevant data available. Where little data exists the model makes significant use of structured expert judgement from technical specialists to populate the model.
The SRM-Risk Profile Bulletin
The results of the SRM are published in the Risk Profile Bulletin. The current version is version 7, published in August 2011. To access this document please visit the RSSB: Rail Risk Portal by clicking on image to the right, where the full version of the RPB can be downloaded electronically.
The SRM-Risk Profile Tool
The SRM -RPT is a risk management tool for industry stakeholders, and is used to quantify the significant causes and consequences associated with each of the 120 identified hazardous events. This enables users to identify key areas of risk associated with their operations and to prioritise their investment in safety, using a risk based approach.
The YDS Safety Risk Model
The Safety Risk Model (SRM) currently covers the operation and maintenance of the mainline railway, including stations, reflecting the requirements at the time the model was developed more than ten years ago.
The Yards, Depots & Sidings (YD&S) project involves extending the scope of the SRM, to incorporate the risk from hazardous events in YD&S sites away from the operational railway. This means that accident frequency and consequence data will be available for YD&S sites for companies to use to help improve their understanding and management of risk on these sites.
