부산항 'A' 터미널에서 발생한 지난 3년간의 사고 데이터를 분석하여 어떤 장비가 가장 많이 사고를 발생하였고 어떤 위험점이 가장 높은지를 위험성 평가기법으로 알아보고, 이러한 사고를 미연에 방지하기 위한 방안을 보우타이 기법을 활용하여 제시하고자 한다. 실증자료를 분석한 결과 터미널 내의 이동장비 중 야드 트랙터의 충돌사고가 가장 높은 것으로 나타났다. 안전한 부산항을 만들기 위하여 우리는 가장 먼저 야드 트랙터의 충돌사고 예방법 (Control measure)과 사고 발생 시 대처방안 (Recovery measure)을 철저히 준비하여 사고를 미연에 방지하여야 할 것이다. 본 연구의 결과는 관련 실무에 다양한 시사점을 제공하였다.

Static-electricity-induced fires and explosions persistently occur every year, averaging approximately 80 and 20 cases annually according to fire statistics provided by the National Fire Agency and industrial accident statistics provided by the Ministry of Employment and Labor, respectively. Despite the relatively low probabilities of these accidents, their potential risks are high. Consequently, effective risk assessment methodologies and accident investigation strategies are essential for efficiently managing static-electricity hazards in fire- and explosion-prone areas. Accordingly, this study aimed to identify the causal variables essential for accident investigations, thereby facilitating risk assessments and the implementation of effective recurrence prevention measures to mitigate static-electricity hazards in fire-and explosion-prone regions. To this end, industrial accident statistics recorded over the past decade (2012 to 2021) by the Ministry of Employment and Labor were analyzed to identify major fire and explosion incidents and related industrial accidents wherein static electricity was identified as a potential ignition source. Subsequently, relevant investigation reports (63 cases) were thoroughly analyzed. Based on the results of this analysis, existing electrostatic fire and explosion risk assessment techniques were refined and augmented. Moreover, factors essential for investigating electrostatic fire and explosion disasters were delineated, and the primary causal variables necessary for effective risk assessments and scientific investigations were derived.

Great concerns on geotechnical risk & hazard assessment have increased due to human and economic damage by natural disasters with recent global climate changes. In this paper, geotechnical problems in particular, landslide which is interested in European countries and North America, were mainly discussed. For these, 18 key topics on geotechnical risk and hazards which had been discussed at the LARAM 2008 workshop in Italy were analyzed after grouping by subjects. Main topic contents consisted of applications such as field measurement, early warning systems, uncertainty analysis of parameters using radar, optical data and statistical theory and so on.

This paper presents a study on the assessment of electrical fire hazards by electric circuits with leakage. The hazards are evaluated with the energy supplied by earth-leakage currents which flow in the circuits simulating the actual circuit of domestic premises. Also, operating time and current of ELB are measured by an experimental approach. A common specification of ELB used in this paper has a sensitivity of 30[mA] for leakage current working on the current-balance principle. Total charges and energy of leakage currents are calculated quantitatively by a theoretical approach and compared with the results obtained from experiments.

안전과 관련된 CNS/ATM 시스템의 개발은 안전 평가 활동을 필요로 한다. 안전 평가에는 기능 위험 평가를 포함하며, 이는 시스템의 위험한 상황을 감소시키기 위한 시스템 안전 요구사항을 도출하는데 영향을 끼친다. 본 논문은 A-SMGCS에 대한 기능 위험 평가에 대한 사례 연구를 수행하였다. 이를 위해 관련연구인 Eurocontrol과 EMMA에서 수행한 연구를 분석하였으며 Eurocontrol 및 EMMA의 기능 위험 평가 체계를 통합하였다. FHA(functional hazard assessment) 범위뿐만 아니라 FHA를 위한 여러 가정 사항들을 인천국제공항에 대해서 정의하였다. 29개의 위험원이 식별되었고, 각각에 대해 심각도가 평가되었다. 그리고 위험원에 대한 노출빈도와 안전 목적이 이벤트 트리 분석 방법을 사용하여 분석되었다. 본 연구 결과와 EMMA의 결과에 대한 차이를 분석하였으며 또한 본 연구에서의 평가 결과에 대해서도 검토 하였다.

Railway works on or near the line, or trackside works, typically have high potential of accidents, as the works have to be frequently performed during the train operation. In order to reduce the risks associated with the railway trackside works effectively, a systematic risk assessment must be performed considering the hazards that contribute to the accidents. In this study, hazards are identified for railway trackside works by analysing data from Korea Railroad for accidents that have occurred between the year of 2000 and 2006. The hazard list produced in this study is expected to be effectively used for the risk assessment of the trackside works.

This paper addresses issues encountered in using the ISO and national standard codes to assess the hazards of whole-body vibration and repeat shocks. Their assessment methods are given in ISO 2631-1 (1974, 1985, 1997) and BS 6841 (1987) that are now available to us. Two standard codes can yield unfortunately different assessment results even for a single measured vibration signal. Possible reasons for such different results are pointed out and, furthermore, related questions that should be re-examined in the future are raised in this paper.

This objective of safety assessment is to determine the acceptability of risks of hazards, or the coping measures, if not acceptable, by identifying and quantifying the risks potentially involved in incidents, with the information of new technology and the disasterous cases.

The risk management case is an organization's formal arrangement to ensure the safety of its work activity within risk management system. It allows an organization to demonstrate its capability in achieving its safety objectives and in meeting regulatory requirements. This paper presents how the safety assessments are described, prepared and maintained to meet the criteria specified by the upcoming safety regulations. We propose the elements of risk management system that include arrangements for the ongoing identification of hazards, assessment of risks and the implementation of necessary control measures.
