Generic hazard list
A critical aspect of risk assessment is the systematic and comprehensive identification of hazards. A generic hazard list, used as a starting point to hazard identification, makes it less likely that hazards are missed.
New technology has brought many benefits to the GB rail industry, but at the same time it increases the complexity of processes and standards to assure its safe introduction. If the safety management of change is not managed effectively, then it can lead to significant costs and delays, as key safety issues can emerge late in the project lifecycle, requiring costly fixes or creating the inability to demonstrate safety. If the identification of hazards is done in a bespoke manner for each project, considerable effort may be required, and may repeat work done elsewhere. In addition, key hazards may be missed.
Research project T955 “Hazard Analysis and Risk Assessment for Rail Projects” developed an initial list of hazards for rolling stock that were compiled from the hazard lists used by three major train manufacturers.
Further work is planned that will extend this list to cover hazards resulting from the entire railway system. Ultimately it will become possible to link safety requirements in standards to hazards.
