FTA-FMEA-based validity verification techniques for safety standards
E-mail:
Scientific and technological advances have yielded a plethora of benefits, but the associated risks have increased as well. Although numerous safety standards have been established for various applications, these standards have not been adequately verified. In this study, a method is proposed for prioritizing safety standard priorities on the basis of minimal cut sets. In addition, safety standards obtained through fault tree analysis are applied to the breakdown modes and accident cause removal methods of failure mode and effects analysis to develop a validity verification method for safety standard sets. The developed method was applied to a gas-boiler exhaust system as a case study, and the validity of the safety standard sets and improvements in the safety standards were verified on the basis of the established safety standard priorities.
