Behind the growth of the chemical industry which is a cornerstone of the Korean economy, dozens of hazardous and noxious chemical accidents occur every year, resulting in enormous casualties and environmental damages. Many cases among chemical accidents are caused by the carelessness of workers in handling facilities such as hydrochloric acid and hydrofluoric acid, and the aging of handling facilities. In order to mitigate the damage by such chemical accidents, a safety system for preventing atmospheric diffusion of hazardous and xoxious chemicals in dike was proposed. The atmospheric diffusion prevention safety system consists of leak detection phase, alarm and measurement phase, suppression and blocking phase. Through the proposed the atmospheric diffusion prevention safety system, the need for 2nd chemical accident prevention such as atmospheric diffusion in dike can be posed.

Recently, due to global warming, the trend shows an increase in number of lightning strikes which increase risk regarding industry infrastructures. Especially in case where the lightning strikes infrastructures including refinery, petorchemical plant facilities or storage tanks, it can cause power failures, electrical machine malfunction and damage which can lead to fire explosion and multiple calamities. Therefore, detailed case studies must be conducted through a systematic research regarding lightning strike accidents in order to understand its mechanism and devise preventive measures. This paper aims to study cases of explosion regarding waste water storage tanks in refineries and petrochemical plants in order to analyze its root cause and provide preventive measures for avoiding lightning related incidents.

한국에서는 석유화학 산업의 역사가 30년 이상이 되어 잠재적인 사고의 위험 가능성이 높아지고 있다. 지금까지의 석유화학 산업에서의 전통적인 위험성 평가와 시스템의 제어는 기계적인 결함에만 중점을 두었기 때문에 인간의 행동을 제어하는 것은 간과하여 왔다. 비록 자동화 기술가 제어기술의 발전이 필요함에도 불구하고 인간의 의사 결정 요소는 석유화학 산업에서 사고를 예방하는데 필수적이다. 대부분의 심각한 사고는 부적절한 인간의 행동과 안정장치의 기계적인 결함이 동시에 존재할 경우에 발생한다. A-HRA(Advanced Reliability Analyzer) 소프트 웨어는 석유화학 플랜트 내에서의 인적오류 확률을 분석하고 사고 데이터를 축적하기 위하여 개발되었다. A-HRA 프로그램을 이용하여 1960년대 이후부터 최근 까지 한국의 석유화학 산업에서 발생하여온 인적오류 사고 데이터를 입력하고 사고마다의 근본원인과 수행영향인자를 분석하였다. 이 본문에서는 Root cause Aanlysis을 통한 결과와 PIF(Performance Influencing Factor) 평가 결과를 보여준다. 이 분석 결과는 석유화학 산업의 안전을 극대화 시키면서도 인적오류 제어를 통하여 안전비용을 최저화 시킬 수 있는 대책을 제시할 것이다.

Each country tries to prevent major industrial accidents at industrial sites, such as fire and explosion as well as poisoning incidents, and regulation of the management of chemicals is being enhanced in all sectors. In particular, in the case of laboratories, a variety of chemicals have been developed and handled in accordance with the development of science and technology. On the other hand, the accident probability at laboratories is higher than at industrial sites, because many different kinds of chemicals are handled in the laboratory but in very small amounts and chemical, physical, and biological studies have been carried out in limited spaces. Recently, the accident probability at laboratories was found to be higher as convergence/integration studies were carried out beyond the academic arena. Therefore, in this study, a survey of chemical management was conducted to prevent accidents due to chemicals targeting the laboratory safety coordinator using the FGI (focus group interview) method. The building plan of a chemical management system was suggested based on the results of the survey.

The purpose of this study is to minimize damage of chemical accidents through the appropriation analysis of evacuation facility position focused on Ulsan metropolitan city. For analysis, informations such as pollutant release and transfer registers(PRTR), population census, and evacuation facilities were used. After then, damage assessment of chemical accidents, accessibility and appropriation of evacuation facilities were analyzed. Damage of chemical accidents is high in around 5km of industrial complex there is dense of chemical facility and population. Evacuation facilities were mainly situated in hazard area of chemical accidents, but accessibility of evacuation facilities was vulnerable in chemical plant neighborhood. Therefore, safety check of deteriorated plants is important for prevention of chemical accidents. Also, effective evacuation plan considering capacity and scale of evacuation facilities will be established.

The major aim of this study was to provide information on the chemical accidents that occurred in laboratories over the last 3 years. The total incidence of laboratory chemical accidents was 30 cases; 25 cases occurred at educational institutions. Most accidents (19 cases) occurred due to spills and leaks. The main cause of the accidents analyzed was worker carelessness (21 cases). Twenty-two accidents were related to hazardous chemical substances. In addition, general chemical substances as well as waste liquid contributed 26% to the incidents related to the laboratory. Among the 22 hazardous chemical substances involved in laboratory chemical accident, 67% of accident substances were accident preparedness substances.

화학물질은 현대문명에 필수적이다. 산업용 원료, 신소재, 섬유, 의약품, 농약 등 화학물질의 사용용도는 광범위하고 그 유용성은 무궁무진하다. 하지만, 언제부터인가 화학물질 유해성(有害性)이라는 용어에 익숙해지고 있다. 화학물질은 분해에 장시간이 소요되어 인체 또는 환경에 잔류하고 장기적으로는 각종 질병을 일으키기도 한다.

Objectives: Based on the results of a chemical substance emissions survey, we investigated characteristics of chemical emissions in industrial complexes and used them as basic data for chemical management. Methods: The emissions and characteristics of chemicals by major industrial complexes from 2011 to 2015 were analyzed using the Pollutant Release and Transfer Register homepage. To understand the status of chemical accidents for major chemicals emitted from the industrial complexes, the Chemistry Safety Clearing-house system of the National Institute of Chemical Safety was used. Results: Emissions from the top five industrial complexes accounted for about 30% of total chemical emissions. The chemical emission was the highest in the order of Ulsan Mipo Industrial Complex and Okpo Industrial Complex. The main chemicals emitted were xylene, ethylbenzene, ethyl acetate, toluene, dichloromethane, and others. Carcinogen emissions differed by industrial complex, but ethylbenzene and dichloromethane were the major chemicals for this type of emissions. Conclusion: Recently, the use and emission of chemicals have been continuously increasing. A chemical management plan should be prepared considering the characteristics of industrial complexes and chemical substance emissions.

Major accidents such as typhoon, tsunami, and chemical accidents have been continuously occurred. In this environment, Technical Commitment (TC) related to disaster management part in the International Organization for Standardization (ISO) concentrates their efforts to enact the business continuous management in emergency situation for international standard. As a result of TC223, four international standards are enacted in 2011, 2012. In the Korean industrial standard, two international standard (ISO22300, ISO22301) out of four standards were enacted in 2012. This study analyzes a recent trend and proposes a method activating of international societal security standard for chemical accidents. Disaster certificate system for developing disaster safety industry is suggested. We hope each related organization could develop our disaster safety management policy and research based on this study.
