In risk assessment, there are several methods such as Safety Review, Checklist, FMEA(Failure Mode and Effect Analysis), FTA(Fault Tree Analysis), ETA (Event Tree Analysis) etc, however, the level of accident is indentified by the probability of accident and severity resulting from accident which used widely in assessing accidents and disasters. In this paper, the risk assessment method to decide the level of risk will be introduced by using severity, frequency and detection according to accident theory.

To prevent cargo accidents by repeated loads, a continuous monitoring for securing rope or additional safety measures are needed, but most of prevention measures have been conducted only by operator's own experience not a quantitative assessment. Hence, the Load-Displacement curve and approximation formula of securing rope were drawn in this research for a quantitative assessment and simplified measurement on a tension of securing rope using a tensiometer. Moreover, a com parison was conducted between m easuring tension and calculated tension on securing rope with portable tensiometer, 'Load-Displacement' approximation formula. The calculated tension of securing rope is obtained 153.3kfg using the formula and that result has not much difference with initial tension 150.0kgf. Lastly, an analysis of the characteristics of various ropes was suggested to enhance the reliability about quantitative assessment of securing rope's tension through further research.

Background: The purpose of the work is to develop a system that allows processing of information for analysis and industrial risk management, to monitor the level of industrial safety and to perform necessary measures aimed at the prevention of accidents, casualties, and development of professional diseases for effective management of industrial safety at hazardous industrial sites. Methods: Risk assessment of accidents and incidents is based on expert evaluations. Based on the lists of criteria parameters and their possible values, provided by the experts, a unified information and analytical database is compiled, which is included in the final interrogation questionnaires. Risk assessment of industrial injuries and occupational diseases is based on statistical methods. Results: The result of the research is the creation of Guidelines for risk management on hazardous industrial sites of the Republic of Kazakhstan. The Guidelines determine the directions and methods of complex assessment of the state of industrial safety and labor protection and they could be applied as methodological basis at the development of preventive measures for emergencies, casualties, and incidents at hazardous industrial sites. Conclusion: Implementation of the information-analytical system of risk level assessment allows to analyze the state of risk of a possible accident at industrial sites, make valid management decisions aimed at the prevention of emergencies, and monitor the effectiveness of accident prevention measures.

Fuel cell powered unmanned aerial vehicles (UAV) are globally being developed for various application according to hydrogen roadmap. However, safety standards for hydrogen fuel cell for UAV have not been established. Therefore, in this study, we derive safety data based on risk assessment to develop safety standards for fuel cells for UAV. We use fault tree analysis method which is broadly used in hydrogen facilities as a risk assessment tool. We set hydrogen leaks and fires as top events and derived the basic events. Safety data for the basic events were derived by quoting overseas safety standards related to fuel cells. The safety data will be used for developing fuel cell inspection standard according to Act on Hydrogen Economy Promotion and Hydrogen Safety Management.

Korea enacted the occupational safety and health law in order to prevent industrial accidents in 1981. Led by ministry of labor, occupational safety and health support services policy has been built through government-affiliated organizations, research institutions and academic research. Korea's accident rate has remained at 0.7% for last 10 years despite continuous efforts over the last 30 years. These results means that the occupational safety and health support services policy conducted by the government have reached their limits. Therefore, the necessity of assessment about occupational safety and health support services policy is proposed. The main objective of this study, through the IPA analysis, is to grasp the point of worker's needs about occupational safety and health support services policy and to help formulate the efficient policy.

Subcontracting business than the contracting business in shipbuilding industry is a lot of hazardous job and highly accident because of highly work intensity. In order to prevent the accidents, there is a need to analyze characteristic. of shipbuilding, to apply measures of risk assessment. In this paper, I suggested an improvement of the risk assessment through the actual condition research in shipbuilding industry. In the research method, I analysed accidents occurred until 2011-2013. Carried out the actual site survey while two weeks in May 2014. As a result, 1) The main pattern were caught-in or between, fall on the high level according to analyzed accidents. 2) To apply the weight show clear of magnitude for risk assessment. 3) Risk estimation of risk assessment is desirable to be quantization by accidents analysis, and to be greater than or equal to 4 steps.

조선소에서 데크 크레인은 지상에 설치된 타워 크레인이나 해상 크레인을 사용하여 리프팅 설치 방법에 의해 선박에 탑재된다. 데크 크레인의 두 점 리프팅 설치 작업 시에는 임시 고정 지그 등을 사용하는데, 안전한 리프팅 작업을 위해서는 고정 지그의 형상 및 설치 위치를 고려한 리프팅 안전성 평가가 선행되어야 한다. 본 연구에서는 데크 크레인 및 고정 지그에 해당하는 유한요소해석 모델을 각각 생성하고, 리프팅 반력 및 경계 조건을 적용한 구조 해석을 수행하여 리프팅 설치 작업에 대한 안전성을 평가하였다. 본 연구에서 제시한 안전성 평가 방법은 다양한 데크 크레인의 리프팅 설치 작업 시에 보다 안전한 리프팅 작업 가이드를 제공할 수 있는 해석적 툴로 활용될 수 있다.
