Safety Risk Model - Risk Profile Bulletin (SRM-RPB)

The Safety Risk Model - Risk Profile Bulletin (SRM-RPB) contains risk information and risk profiles derived from the Safety Risk Model.

On this page you will find an overview of the SRM-RPB and the latest version, currently version 8.

An archive of previous Risk Profile Bulletins is also available.

What is the Risk Profile Bulletin

The SRM-RPB is supported by a range of tools and spreadsheets to help users customise the SRM output to support their particular needs which might include the Safety Risk Model - Risk Profile Bulletin (SRM-RPB) contains risk information and risk profiles derived from the Safety Risk Model.
 
The SRM-RPB is available to download as both an Adobe Acrobat file and MS Excel spreadsheets. The main body of the SRM-RPB sets out:
  • The objective of the Safety Risk Model
  • System boundaries - what the SRM-RPB covers and doesn't cover
  • Changes from previous versions of the SRM-RPB          
  • The total risk results for the GB Mainline Railway
  • Overall risk profiles
  • Details of the HLOS requirements - Passenger and staff safety metrics
  • Detailed risk profiles by accident and person types
 
This this is supported by a suite of tables in the appendices which contain:
  • The frequency, consequence and risk estimates for each hazardous event
  • The frequency and risk contributions for all precursors leading to each hazardous event 
  • A breakdown of risk into key risk areas and selected risk groupings 
  • Details of any key assumptions used in calculating individual risk along with a summary of the calculations for each person type
  • Details of the modeling approach implemented in that version of the SRM
  •  A list of all the assumptions and definitions related to the analysis

 

Why Should I use it?

The SRM-RPB is supported by a range of tools and spreadsheets to help users customise the SRM output to support their particular needs which might include:
  • As Low as Reasonable Practicable (ALARP) assessments and wider business cost benefit analyses of potential or changed control measures. Such assessments and analyses might relate to industry wide investment decisions:
  • Local decisions by transport operators
  • Revision of Group Standards
  • Prioritising areas for research on the railway.
    • Support to transport operators to help undertake suitable and sufficient assessment of the risk from their operations:
  • Identification and prioritisation of issues for monitoring and audit
  • Developing priorities for the Strategic Safety Plan (SSP).
  • The risk estimates presented can be used to support particular risk assessments and for judging how the risk relating to particular operations compares with and contributes to the system-wide risk.

    Risk Profile Bulletin Version 8 - Version Update History

    v8.0: Full SRM update including remodelled hazardous events and data refreshed to 30th September 2013.

    v8.1: Partial update of suicide and trespass hazardous events to take into account new information about specific incidents (see below). The model structure and data cut-off point were unchanged from v8.0.

    In 2013/14, BTP made more information about railway fatalities available to the industry as a result of the enhanced co-operation effected by the National Suicide Prevention Strategy Group.  BTP provided additional information dating back to 2009/10, which has enabled the industry to update the classification of a number of fatalities. 

    Further information on the suicide/trespass data reclassification is available in the Annual Safety Performance Report 2013/14.  Further information on v8.0/v8.1 remodelling is available in the Risk Profile Bulletin.
