A Study on Identification of Hazards for Their Tracking and Management

안전성활동의 추적성을 위한 초기 위험원 도출 기법에 대한 연구

The primary purpose of the safety management is to prevent the loss of lives or physical damages arising from potential hazards in the railroad 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. The identification of potential hazards is the early step of the safety management. However, such identification activities have to be continued during the system life cycle. Further, they have to be closely linked with system functions to prevent functional problems. This study provides a systematic approach to identification of potential hazards for their tracking and management during the system life cycle to assure the identification and definition of the most appropriate hazards.
