AcciMap기법을 활용한 수소충전소 가스누출 사고의 원인 비교 분석

초록

Hydrogen energy is a promising clean energy source, but safety concerns regarding hydrogen gas incidents challenge its widespread adoption. Understanding accident causation through systematic analysis is essential for developing effective preventive strategies. This study applies AcciMap methodology to investigate a hydrogen refueling station incident and proposes a systems-based accident analysis framework. The AcciMap analysis of an actual high-pressure hydrogen refueling station incident systematically examined contributing factors across organizational levels. Compared to the official investigation report, the AcciMap model identified more extensive organizational and regulatory deficiencies, including insufficient maintenance protocols. The analysis identified 20 contributing factors with corresponding safety recommendations. The findings demonstrate that AcciMap methodology enables comprehensive, multi-layered accident causation analysis. This research suggests that systems-based analysis tools can significantly enhance safety management in hydrogen infrastructure development and operation.
