건설현장에서 도로개설, 터널굴착, 시가지 고층건물 지하굴착 등으로 화약류의 사용은 날로 증가되고 있으며, 이로 인한 화약류의 사고도 비례하여 증가하고 있어 점차 사회문제화 되고 있다. 본 연구에서는 이미 개발된 발파사고의 분석에 필요한 사고조사표와 이를 이용하여 발파사고를 체계적으로 분석한 FTA기법 분석에서 발파사고 중 가장 많은 비율을 차지하는 인적원인에 대한 체크리스트를 개발하였으며, 이를 이용한 현장에서의 적용에 대한분석을 실시하였다. 그 결과 발파작업 중 가장 힘들고 불편한 공정인 장전작업에서 가장 많은 오류가 발생하였으므로 이에 대한 개선 작업에 관심을 기울여야 할 것으로 생각된다.

This paper investigates the construction equipment accidents by time. Construction sites are unique with many different hazardous conditions which cause accidents. According to the Occupational Safety and Health Administration (OSHA), accidents related to construction equipment are one of the most leading causes of fatal injuries in the construction industry. While there have been many studies investigating the equipment-related accidents, few research studies provided in-depth analyses about the time that accidents frequently occurred. By using the OSHA accidents data collected between 1997 and 2012, this paper analyzed the accidents data by time, equipment type including excavator, backhoe, dozer, and crane, accident cause, and injury class. The analyses revealed that the time window with most accidents was between 13:00 and 13:59. In terms of the injury class, the time windows with the highest numbers of equipment accidents were between 13:00 and 13:59 and between 11:00 and 11:59 for fatality and hospitalization, respectively. For the accident causes, equipment operator's error was the highest number of accident causes. It is expected that findings from the analyses can be used to more strategically develop management plans and guidelines to prevent accidents related to construction equipment to practitioners.

The safety accident is one of the formidable issues in construction field, and in order to prevent safety accident, contractors perform safety education, safety control document, meeting with labors, and safety instruction in construction phase. However, safety accident is occurred continuously, it is needed to analyze which factors are affected to safety accident. day of the week, daily construction cost, and daily work task were selected as those factors. The result in this research represented that those factors were not considered as an critical one in safety accident. Because of approach limitation to safety accident, only two case studies were collected. If more safety accident cases are gathered in future study, it will clarify the cause of safety accident and will prevent safety accident.

The study has suggested a way to minimize safety accidents found in on-site firefighting activity by analyzing firefighters' [investigation report on accidents to on-sie workers]. The study result is described as follows. First, the result of [investigation report on on-site workers] shows that while accidents are found to most frequently have occurred to low-ranking firefighting officers such as Sobangsa and Sobanggyo and firefighting officers with career of less than 5 years, fire-extinguishing activity proved to be the most prone to accidents in the category of activity. Second, analysis performed to identify variance between injury extent and area based on cause of accident shows statistically significant variance. In addition, the result of verifying difference in cause of accident based on category of activity shows significant difference with 'falling over and sliding' being the highly likely cause of accident in fire containment and rescue activities and 'reckless move' being highly likely case of accident in emergency activities. Third, the result of verifying factors behind the extent of injury done to on-site workers shows that when accident is caused by 'incomplete behavior', it was found that the extent of injury is substantial. It was also found that rescue activity is accompanied by substantial extent of injury. As a solution to this, the study suggested ways to establish, extend and operate safety-specific curriculum for entrants, develop materials regarding risk prognosis training and explicate training-related regulations, set up safety management measure for a single squad team, upgrade performance of private protection equipment, institutionalize SOP by on-site activity stage, materialize and activate swift rescue team and increase objectivity and proficiency of safety accident investigation.

선박 시스템은 복잡하고 고도화되어 있으며, 각 요소 간 업무연관성이 굉장히 높다 보니 관련된 사고를 예방하기 위해서는 사고를 분석할 때 사고의 직접적 원인을 찾아 제거하는 전통적인 순차적 접근방법에 더하여 전반적이고 통합적인 시스템의 측면에서 접근할 필요가 있다. 이에 본 연구에서는 전통적인 사고분석 기법과는 다른 STAMP 방법론을 사용하여 선박에서 발생한 화재사고를 분석한다. 이 분석을 통해 선박 내 화재를 예방하기 위한 안전 요구 사항, 부적절한 결정과 조치, 상황, 장비 결함 및 사고분석 결과에서 도출된 권고 사항을 포함한 다양한 요소를 검토한다. STAMP를 이용한 사고 예방에 대한 종합적인 접근을 통해 선박이라는 전체 시스템 내에서 구성 요소 수준에서 대안 평가를 제시하고, 단순한 사고분석 뿐만 아니라 사고 예방 및 위험 평가에도 체계적으로 활용하고자 한다.

The purpose of this study is to attempt a systems approach to press injuries using Fault Tree Analysis. Three major techniques were used: Industrial Accident Dynamics (IAD) by which accident analysis can be made, Fault Tree Analysis (FTA) by which quantification of accident analysis can be made, Computerized Algorithm by which minimal cut set to accident can be identified. A survey has been made of ninety two cases of press injuries from seven industrial firms. All cases of the accident are analyzed using the three techniques. According to the analysis, lack of safety knowledge and improper scaffold seem to be the primal cause of accident. Comparisons of the accident causes to actual accident reports (National Institute of Labor Science) demonstrates that the FTA is a powerful tool for industrial accident prevention. On the basis of this result, some countermeasures are discussed.

The frequency of car accidents is very high at the intersection. Because of the state of a traffic signal, quarrels happen after accidents. At night many cars run away after causing an accident. In this case, accident analyses have been conducted by investigating evidences such as eyewitness accounts, tire tracks, fragments of the car or collision traces of the car. But these evidences that don't have enough objectivity cause an error in judgment. In the paper, when traffic accidents happen, the traffic accident detection system that stands on the basis of images and sounds detects traffic accidents to acquire abundant evidences. And, this system transmits 10 seconds images to the traffic center through the wired net and stores images to the Smart Media Card. This can be applied to various ways such as accident management, accident DB construction, urgent rescue after awaring the accident, accident detection in tunnel and in inclement weather.

The objective of this study is to develop qualification analysis preliminary frame for railway personal injury accident. In this research, we develop accident scenarios to analyze systematically and evaluate quantitatively fatality accident scenarios for railway personal. The accident scenario analysis first identifies the hazardous events and explains the hazardous conditions that surround the accident and cause railway accidents. This method includes a feasibility test, a clustering process and a pattering process for a clearer understanding of the accident situation. Since this method enables an accident scenario analysis to be performed systematically as well as objectively, this method is useful in building better accident prevention strategies. Therefore, this study could serve to reduce railway accidents and could be an effective tool for a hazard analysis.

본 연구는 화학물질 운송 화학사고를 대상으로 각 연도별 사고현황, 사고유형, 사고원인 등의 화학사고 특성을 분석하였다. 그 결과 77건의 운송 화학사고 중 74건이 유 누출 유형에 의한 사고였으며, 사고 원인으로는 41건이 교통사고에 의한 화학사고였다. 또한, 사고다발 화학물질 조사에서는 46건의 사고가 유해화학물질에 의한 사고인 것으로 조사되었다. 화학물질 운송 화학사고의 예방 및 대응을 위해서는 화학물질 유 누출과 화학물질의 운송 교통사고에 의한 화학사고에 대한 예방책의 보완이 필요하며, 운송 화학사고가 발생되었을 경우 방재가 시스템적으로 신속히 이루어질 수 있도록 범국가적이고 체계적인 화학물질 운송안전 시스템을 구축하여 화학물질 운송에 적용하는 것이 필요하다.
