Use of a Generic Hazard List to Support the Development of Re-Usable Safety Arguments in the Rail Industry

Abstract The paper describes an ongoing research project to produce tools and guidance to support the rail industry in undertaking engineering safety management activity in accordance and clear compliance with the requirements of the European railway regulation for the ‘Common Safety Method on Risk Evaluation and Assessment’ (CSM on RE&A) [6]. A key aspect of this work is the development of generic hazard lists to support: ii Demonstrable application of the CSM on RE&A.iii Use of the process to support the consistent management and transfer of hazards between different parties involved in a significant change project relating to rolling stock. The research project has developed a draft generic hazard list for rolling stock hazards. This followed a review of several hazard lists produced by manufacturers and operators. This hazard list is being used as a consistent basis for risk assessment and management processes that are performed under the framework. RSSB has identified the ‘Codes of Practice’ (eg in Railway Group Standards, and European standards) that form part of the ‘System Definition’ or that provide mitigation of the risk of certain causes of the generic hazards in accordance with the framework. Using a generic system definition various mappings are being produced from the ‘System Definition’, to causes of the hazards, to the safety requirements. The intent is for these mappings to support a template approach to application of the CSM with fragments of the argument being able to be re-used and adapted over time as successive projects prove their validity. This will ensure the safety work is both cost effective and suitable controls and their importance are appropriately identified.
