연구목적: 본 연구에서는 국외 선진 조사기구의 운영현황을 조사하고 착안점 도출을 통해 우리나라 조사기구가 나아가야 할 방향을 고찰하고자 한다. 연구방법: 미국, 일본, 스웨덴 등 선진 조사기구의 설립배경, 조직구성, 주요업무 및 기능, 사고조사 절차 등 조직 운영 현황과 기능을 조사하였다. 연구결과: 첫째 모든 조사기구들의 설립 목적과 기능은 유사 재난·사고의 재발방지를 위함이며, 원인조사, 법·제도·정책 등의 개선권고, 권고사항에 대한 이행점검 등을 주요업무로 하고 있다. 둘째, 중립적 입장에서 공정한 조사가 가능하도록 부처 소속이 아닌 대통령 직속의 독립기구로 운영하고 있다. 셋째, 조사결과의 전문성을 인정받을 수 있는 권위를 보유하고 있다. 즉, 전문성 축적이 가능한 상시 전문인력 확보를 통한 상설조직으로 운영하고 있으며, 심층조사와 수준높은 권고안 마련을 통해 조사결과에 대한 권위를 확보하고 있다. 결론: 국외 재난조사 기구는 국가적 요구와 사회적 재난 갈등을 해소하기 위해, 원인조사의 공정성, 정확성과 전문성을 강화함과 동시에 독립성을 확보하고, 대규모 재난시 국가 차원의 신속한 사고조사 운영실태를 총괄·조정하기 위하여 조직의 위상을 확보하고 있다. 유사재난·사고의 악순환이 반복되는 것을 방지하기 위해서 우리나라는 부처별로 분산된 조사 기능을 효율적으로 연계할 필요가 있다. 또한, 다수부처와 관련된 재난·사고 발생 시 국가차원에서 총괄·조정 및 컨트롤타워를 구성·운영할 수 있도록 제도적인 개선이 필요하다.

Recently, various engineering approaches have been widely used in the accident investigation field to identify the cause of the accident and to predict damage by accident. Computational analysis is the most commonly used method of accident investigation technique. This technique is mainly used to identify the mechanism of the accident generation and to determine the cause when it is difficult to reproduce the situation at the time of the accident or when it is impossible to perform a reproduction experiment. In this study, The computational fluid dynamics analysis for nitrogen asphyxiation accident generated by defect of building structural between diffusion outlet and cooling tower was performed to determine the inflow path of the suffocation gas, death possibility by concentration of suffocation gas and predicted the time of death due to the accident using 3D modeling and FLACS program. We can quantify diffusion concentration of asphyxiation gas and predict mechanism of death occurrence by accident and evaluate the consequence Analysis through this study. In the future, This method can be widely used in the field of gas safety by improving the reliability and validity of the analysis.

Objectives: This study was conducted to determine firefighters' work-related accident rate and investigate the factors affecting their on-site safety. Methods: We developed a web-based self-reported questionnaire designed to inquire into firefighters' work-related accident experience and the factors (4M; Man, Machine, Media, Management) affecting firefighters' on-site safety. We distributed questionnaires to all members of firefighting organizations in South Korea by e-mail and 9,149 were returned, resulting in a response rate of 23.1%. Results: Fifteen point seven percent of the respondents reported work-related injuries within the past one year, and 35.1% answered that current accident investigation reports are not helpful for preventing the same accident from recurring. Among the 4M factors, the one most affecting firefighters' on-site safety in the order of priority is the Man factor, followed by Machine, Media, and Management. However, the results from detailed sub-categorical factors showed some differences. 'Lack of human resources', one of the Management factors, was the most influential (70.3%), followed by 'worn-out equipment' under the Machine factor (67.2%). The viewpoint of elements of the Man factor including 'forgetting instructions' and 'fatigue and illness' were significantly different according to firefighters' rank. The higher the firefighter's rank, the more they answered 'forgetting instructions,' while the opposite was the case for 'fatigue and disease'. Conclusions: The present firefighters' accident investigation report needs to be improved, and the 4M method could prove very useful. In addition, it is necessary to set up a proper firefighters' accident investigation and prevention system.

A Recently elevator accidents were occurred and increased due to carelessness of user and violent behavior. The accident of door detachment in elevator platform by electronic motor scooter show a example of safety concerns and insensibility for safety awareness. In this report, we review the cause of accident of door detachment in elevator platform by electronic motor scooter, and show some suggestions of preventing from the safety concerns about this case.

In this paper, the elemental components and improving purpose in advanced safety management system are reviewed to cope with a railway fire accident. And a considering procedure(V-cycle) of long-term plan for railway fire safety improvement is proposed. For the purpose of preventing recurrence of accident, items which have to be considered in the course of accident investigation and cause analysis are presented according to the stage of investigation activity.

지하사고가 발생할 경우 신속하게 원인을 파악하고 인적, 물적 피해를 줄여야 한다. 지하사고조사위원회는 발생한 사고의 원인을 규명하고 이후 동일한 사고가 발생하지 않도록 대응방안을 마련하는 역할을 한다. 그러나 지하사고조사위원회 운영 기간이 최소 6개월에서 최대 9개월까지 활동할 수 있도록 법에 명시되어 있어 실질적으로 동시간대에 추진 중인 건설 사업에서 사고조사보고서를 인용하고 검토를 통해 자체사업에 반영하기에 어려워 보인다. 본 연구에서는 기존에 3개월이 소요되던 자료수집과 분석을 최대 1개월 이내로 단축시킬 수 있도록 현장에 출동하여 자료를 수집하고 디지털트윈으로 구현하고 제공함으로써 지하사고조사위원회가 의사결정을 신속하게 할 수 있는 기술개발 전략을 수립해보고자 했다. 연구결과 5개 기술개발 분야인 지상 데이터 수집·전송기술, 지상안전 데이터 생성기술, 디지털트윈 기반 지하안전 분석·가시화 기술, 디지털트윈 기반 지오앰뷸런스 구축·운영 기술, 디지털트윈 기반 지오앰뷸런스 표준화 및 법제도 연구를 도출할 수 있었다. 제시된 기술이 개발된다면 기존대비 신속한 의사결정을 통해 사고현장을 줄이는데 기여할 수 있을 것으로 보인다.

Most human-error case of accident database is written by various description and expression because accident database is produced by two or more person. And extracted information by searching of database varies in researcher's judgment criteria and the capability. Furthermore, much time and effort are required to examine manually information related to the human error from each accident case. Accordingly, it is difficult to explore objectively the accidents relevant to the human-error from the accident data base which is accumulated enormously. In this study, to solve these problems, it was developed an searchig method which is not influenced by researcher's judgment criteria and capability. For this, human-error keywords were extracted from a Japanese-English dictionary to examine objectively the accident case related to human-error in data base. This searching method by the human-error keywords can be applicable in most accident databases, although a database will be accumulated in future. Also, using the searching technique of this research, knowledge obtained by searching result can be compared with other research's results by the same method. Although the number of accident case increasese, searching results from database have the objectivity because it is not necessary to modify the based searching method or change the human-error keywords. However, as subject of future investigation, it would be necessary that the extension and investigation on human-error keywords improve and the technique to enhance searching accuracy would be modified.

Cause of Bucheon LPG refueling station accident could not be clearly verified because of opposite talking of men reponsible for the accident the accident, damaged by BLEVE and fire, and no systematic fire investigation. After two and half years, recently first judgement has been carried out. But competitive arguement is going on and first leak point of massive LPG will not be clearly identified with evidences acquired by now. This accident gave us many instructions and advices. Specially, massive LPG leak can result in pool fire and safety of underground-installed storage tank is proved by no damage in the strong BLEVE.
