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 template tool 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 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 results of the SRM are published in the Risk Profile Bulletin. The current version is version 6, published in June 2009. 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.
