  • Forklift truck is one of the dangerous machines which causes the fatal accidents most frequently. The causes of fatalities by forklift from 2008 to 2011 were analyzed. Crushing the operator when tipping over or falling off a truck were the major causes of death in this study. The purpose of this study is to show measures from the engineering point of view to prevent the forklift truck accidents. In order for that, the domestic requirement for forklift safety was compared with those of foreign and international standards. The manufacturers' opinion was also collected regarding to improve the forklift safety. Several measures were suggested in order to prevent fatalities caused by forklift.

  • Mobile scaffold is used as a work platform in construction sites. According to industrial accident data, 10 fatalities occur annually on average due to falling from mobile scaffold in construction sites. To prevent such fatal accidents, safety standards must be improved by analyzing the causes of fatal accidents related to mobile scaffold. Accordingly, we analyzed domestic and international safety standards for mobile scaffold and analyzed the fatalities (117 persons) caused by mobile scaffold accidents in domestic construction sites during 2011-2020 and found that fall, overturn, and collapse accounted for 88% (103 persons), 10.3% (12 persons), and 1.7% (2 persons) of fatalities, respectively. The main causes of fatal accidents were found to be non-installation or insufficient installation of safety rails and outriggers and incorrect sequence of work. Based on the analysis results, we proposed strategies for improving the safety standards, such as the use of advanced guard rails and wheel-attached outriggers, to enhance the safety and field applicability of the mobile scaffold. Technology development and improvements in the safety standards for the use of mobile scaffold will aid in the prevention of fatal accidents caused by mobile scaffold.

  • 우리나라의 도로는 종류별로 관리주체가 서로 다르다. 고속국도는 한국도로공사, 일반국도는 건설교통부, 지방도는 광역자치단체, 시 군도는 기초자치단체에서 건설 관리 및 운영 책임을 맡고 있다. 본 연구에서는 이렇듯 관리주체가 다른 우리나라의 도로에서 발생하고 있는 교통사고발생 추세를 도로종류별로 분석하는데 목적이 있다. 이를 위해 과거로부터 축적된 도로종류별 교통사고건수, 사망자수, 부상자수의 자료를 기반으로 사고위험을 단순건수, 도로연장 당 건수, 그리고 대 km당 건수로 비교하였다. 그 결과 단순 건수에 의한 비교에서는 도시부 도로가 전 부문에서 가장 위험하고 고속국도는 전 부문에서 가장 안전한 것으로 분석되었다. 그러나 1km당 발생건수는 일반국도가 가장 위험하고 지방도가 가장 안전한 것으로 분석되었다. 교통사고 발생률을 가장 객관적으로 비교할 수 있는 지표인 10만 차량 대 km당 비교에서는 일반국도가 가장 위험하고, 고속국도가 상대적으로 안전한 것으로 분석되었다. 한편, 도로종류별 사망자수 추세를 설명하는 시계열 분석모형을 개발한 결과 고속국도, 지방도, 도시부도로의 경우 AR(1)모형이 추세를 잘 설명 할 수 있는 것으로 분석되었고, 일반국도의 경우 ARIMA(2, 3, 0)모형이 추세를 설명할 수 있는 것으로 분석되었다. 이러한 모형은 장래 교통안전계획의 목표치를 수립하거나 평가하는데 근거자료로 활용될 수 있을 것으로 보인다.

  • As accident rate have been reduced into half since 2005, no train accident fatality occurred in recent year. Level crossing accident also been reduced that no more than 5 fatalities occurred every year. As a result 98% of accident fatalities occurred in station and track. So railway station safety measures are more and more important but only few research have been done on railway station safety. In this study status on safety measures on railway stations are reviewed and basic research have been done based on expert interview for the development of new safety measures.

  • Though the probability of tunnel fire accident is very low, but critical fatalities are expected when it occurred. In this study the effect of critical safety parameters on tunnel fire accident are examined using probabilistic technique. Fire detection time, smoke spread velocity, passenger escape velocity, flash-over time, and emergency service arrival time are considered. In order to estimate the uncertainties of input parameters Monte Carlo simulation are used, and fatalities for each assumed accident scenarios are obtained as results. For the efficiency of iterative calculation PRA(Probabilistic Risk Analysis) code is developed in this study. As a result fire detection have large effect.

  • Airbag systems have improved the occupant safety in reducing the injuries of driver and passenger during collisions. They have occasionally caused fatalities; especially to small occupant and children. Recent airbag related fatalities of children have raised serious concerns on how to evaluate the safety of children in various crash environments. This paper present the development of the 3-year-old human model. Child human model is composed of skin, skeleton and joints. The positions of joint and mass properties of body segments are calculated from ARB(Ariticulated Rigid Body) program GEBOD. To verify the developed human model, ROM simulation and OOP simulations are conducted.

  • This paper describes a study to determine proper escape way interval for the design phase of single bored double track tunnel. Among many methods which determine escape way interval, we choose a QRA(Quantitative Risk Analysis) method. But a different method must be chosen differ from other country because of special design situation of Korea. So, it is necessary to develop a method which considers a special design condition of Korea. Because fire accidents of railway tunnel are a rare event, simulated situation can be produced by CFD simulation and evacuation analysis simulation. However, it is generally difficult to estimate of fatalities from these methods, so a concept of FED is introduced to estimate of fatalities. Quantification process provides effective results for practical design stage and the result were employed in design.

  • Everybody may be vulnerable to fires depending on the time, place, and circumstances. Fire statistics show that the occurrence of fire death depends not only on the severity of a fire itself, but also largely on the conditions of occupants such as physical functions, the environment around occupants, and the type of facility where are fire occurs. The review of fire safety from the viewpoint of vulnerable populations does not simply mean additional special attention and care only to high risk groups, but instead it means significant review of fire safety design and systems for all people from a more universal standpoint. Therefore, in order to examine the strategies of a fire death-reduction program, safety measures suitable for the relevant high-risk groups considering the type of vulnerable person, the type of fire, and the type of building in residential occupancies. Solutions will require strenuous multilateral effort and flexibility.
