산업발전과 신제품 개발에 따른 연구업무의 중요성이 증가함에 따라 실험실의 수행 업무도 복잡 다양해져 새로운 형태의 잠재위험 요소가 증가되고 있다 실험실의 위험요소는 기계·물리적, 화학적 및 생물학적 위험이 있으며, 주로 화재·폭발, 중독 둥 실험실 사고에 따른 인명손실이 발생되고 있어 실험실 사고예방을 위한 자율적인 실험실 안전관리를 위한 노력이 필요하다. 또한, 실험실에서 사용되는 각종 유해화학물질, 설비 및 기기사용에 따른 위험성 등 실험실의 안전보건에 관한 관심이 고조되고 있다.(중략)

본 논문에서는 지역별로 발생 양상이 다른 사회재난의 종합적 위험분석을 위한 정보활용 방안 및 전략을 제안한다. 사회재난은 재난유형이 매우 다양하며, 각기 다른 발생 및 전파양상을 가지고 있어 전문성을 기반으로 관계하고 있는 개별부처에서 각각 관리되고 있다. 재난이 발생 후 대응, 수습 및 복구에 이르는 활동은 대표적인 현장대응 부처인 행정안전부, 경찰청, 소방청 등에서 주로 담당하고 있으나, 예방 및 대비 활동은 각 부처에서 개별법령에 의한 제도 및 정책에 의해 위험요소를 저감하기 위한 활동으로 진행된다. 예를 들어 화학사고의 경우 화학사고예방관리계획서, 장외영향평가, 화재는 방화지구, 화재경계지구, 산불은 산불취약지수 등 각각의 물리적 매커니즘을 적정히 고려하는 이론적 근거의 의해 사전에 그 위험을 평가하고 있으나 재난관리 예방을 담당하는 부처에 까지 연속성을 가지고 그 결과들이 적극적으로 활용되고 있지 못하고 있다. 이에 본 연구에서는 각 부처에서 개별법령에 의해 평가되는 공신력 있는 자료들의 융합적 해석에 근거한 종합위험 평가 개념을 정립하고 실제 활용 가능성에 대해 논하고자 한다.

화학물질을 대량 취급하는 사업장은 화재$\cdot$폭발 및 독성물질 누출 사고가 발생할 경우 사고의 영향이 사업장 내부는 물론 인근 주민과 주변 환경에까지 영향을 미칠 수 있기 때문에 무엇보다도 사고의 예방이 중요하나 일반적으로 공정설비의 규모가 크고, 운전$\cdot$변경 성능유지$\cdot$보수 등에 있어 고도의 전문성이 필요하며, 사고의 위험요인이 다양하기 때문에 타 산업에 비해 안전성 확보가 어려운 실정이다［1］.(중략)

This research was performed to propose domestic standard for design and management of flexible hose by analyzing chlorine leak caused by breakage of the hose in Ulsan, 2018. The leak had multiple causes but this paper focuses on analyzing the cause of breakage of flexible hose, the direct cause. According to the analysis, flexible hose that the company of the accident used for chlorine transfer was inappropriate in several aspects including material and wall thickness. And even pressure test had been conducted below operating pressure. Upon investigation on five companies that handle chlorine in Ulsan, four companies were using inappropriate flexible hose for chlorine transfer. Since there is no domestic standard for the design of flexible hose for chlorine transfer at present, it is hard to examine its design adequacy. Design standard of flexible hose used in chlorine transfer that is applicable domestically is proposed based on this research. It will contribute to the reduction in risk of breakage of the hose if the proposed standard could be applied in design and examination of flexible hose.

Chemical accidents are systematically managed by the Chemicals Control Act. However, the definition and case studies of violent incidents by hazardous chemical substances need to be adequately organized. In this study, we focused on suggesting improvement directions of the legal and institutional system to prevent the violent incidents of hazardous chemical substances by studying the problems of current legislation and drawing up implications through domestic and foreign cases. The suggestions for improvement are as follows: 1) Strengthening prevention through amendment of laws (1) Selection of the competent department; 2) Enforcing regulations on online and offline commerce (1) Setting personal purchase amount; and 3) Increasing public awareness and public education (1) Improvement of the continuous system through the Chemical Evaluation Committee.

The causes of accidents occurring in chemical plants vary, but 96% of industrial accidents occurring worldwide are caused by workers' unsafe behavior. The International Labour Organization (ILO) has announced 20 elements of workers' anxiety-warning behaviors that occur on multiple occasions at industrial sites in order to warn them of the risk of accidents caused by workers' anxiety-driven behavior, and to prevent industrial accidents, workers' anxiety-driven behavior should be controlled under stress In this study, major types of unsafe behavior were analyzed on the basis of information on the accident investigation history of domestic workspaces in order to find out how workers can manage their unsafe behavior. Based on the results of the analysis of the major anxiety war behavior, the root cause of causing anxiety war behavior was analyzed using the Swiss Cheese Model, and each root cause management method was proposed.

Currently chemical plant risk have been issued by occurring frequent accidents. Accidents can be generally composed of fire, explosion, release in chemical plant. In case of fire and explosion, accident victims are occurred immediately after accident but release accident, late emergency response cause damage to worker. Especially, there are many victims by late emergency response against chemical exposure to skin. In case of chemical exposure to skin, irreversible damage like death, blindness, burn can be prevented by washing immediately. Safety shower can provide the cleaning for chemical exposure to eye, skin. Most of chemical plants are built in 1980s so equipment become superannuated. In this reason, safety shower also cannot operate normally in emergency situation. Therefor safety shower should be managed by installation and management guideline. This study perform the establishment guideline for safety shower installation and inspection to increase the reliability.

Chemicals are widely used throughout society, and usage is expected to increase in the future. As a result, various accidents related to chemicals and dangerous substances are occurring, and the frequency of occurrence is expected to continue to increase. Thus, it is expected that this study will present problems and improvement directions through analysis of each associated agency's accident report and management system, and improve the research input system to increase efficiency in collecting and statistical calculation of chemical and hazardous accident.

Based on the cases of fire and explosion accident in the chemical reactor, thr problems of preventive measures installed in the chemical reactor were analyzed. The chemical reactors produce a variety of chemicals and install rupture disk to relieve the pressure that rises sharply in the event of a runaway reaction. In order to maintain the function of the rupture disk, the emissions was allowed to be discharged into the atmosphere, resulting in fire and explosion accidents. As a way to improve this, safety instrumented system based on the safety integrity level(SIL3) was applied as a preventive measures for chemical reactor. Two emergency shur-off valves are installed in series on pipe dropping raw materials for chemical reactor so that the supply of raw materials can be cut off even if only one of the two emergency shut-off valves is operated during the runaway reaction. The automatic on/off valve is installed in parallel in the supply pipe of the reaction inhibitor so that the reaction inhibitor can be injected even if only one valve is opened at the time of the runaway reaction.
