Hazard identification is most important in safety activity. But hazard identification is vague and wide extent, error(mistake) happens to safety activity. This paper defined breakdown that hazard by Systematic failure and Random failure. So, for the specification example, show that can achieve systematic analysis and management. This method is recommanded in EN50129. Applied this method to railway signal system in this paper.
열차제어시스템 안전성활동 프로세스에 대한 연구(매뉴얼기반)

The primary purpose of the safety management is to prevent the loss of lives or physical damages arising from potential hazards in the railway signaling system. Since such potential hazards may occur at any time during the system life-cycle from design and development to maintenance safety management activities have to be continuously taken in the course of the system life-cycle. In this paper presented for Safety Activity Process. (Phase Methods Documentation)

In this study it is researched to the hazard analysis phase which is the core phase of the safety life cycle carried out by various systems in Korea. At present diverse methods are utilized when the hazard analysis is performed. With the basis of these V&V activities are carried out. In this study using FMEA which is one of the representative methods of the hazard analysis, the effective and viable result is derived. Also, it establishes the systematic base of the further phases of the safety life cycle such as the Hazard log, V&V, and the safety case.
