The railway safety legislation in Norway was Updated 2006 and one of the major changes is that EN 50126 became mandatory for all new or significantly modified infrastructure projects. Although the hazard log is a central element in the EN 50126 safety management philosophy, the guidance provided within the standard on its practical implementation is very limited. Additionally, the requirements are formulated on a high-level only. Projects and organizations are therefore subjected to a trial-and-error process in order to arrive at a worthwhile and workable level during the initial phase of implementing the hazard log. The hazard log is, according to this EN standard, supposed to constitute the basis for the ongoing risk management. Additional requirements regarding the hazard log are found in subsequent phases of the RAMS (Reliability Availability Maintainability and Safety) lifecycle. Throughout the time-period of establishing the format of the hazard log and defining the type and extent of information to be entered into it, a number of difficulties were encountered. This paper discusses challenges and practical solutions adapted regarding implementation of a hazard log in a large railway infrastructure project.
