지난 60년간 일본, 한국, 중국은 물론이고 아시아에서의 공정 산업은 크게 성장했다. 그 발전과정에서 다양한 사고들을 겪고 극복해내는 과정이 있었으며, 최근 한국의 화학물질관리법을 포함하여 안전 기술 및 안전 관리에 많은 진전 또한 있었다. 이 발표의 서두에서는 한국의 공정산업의 역사적 발전에 대해 뒤돌아보며 당면 과제들에 대한 논의를 전개하고자 한다. 장기적인 경제발전의 일환으로 중화학공업 육성을 표방하며, 초기 단계에 정부주도의 적극적인 산업 발전 계획을 수립해 산업의 성장을 주도하였으며, 1990년대에는 어려움을 극복하기 위해 시장 중심의 구조 조정이 도입되었다. 지난 30년 동안 한국사회에서는 가스 폭발, 건물 붕괴, 화물 및 여객선의 사고를 비롯한 치명적인 사고들이 있었다. 이러한 사고 후에는 필연적으로 안전 정책 및 법률에 중요한 발전이 있었는데, 가장 최근의 것은 2012년 유독 가스 배출 사고 이후 화학물질관리법(Chemical Control Act)을 시행한 것이다. 또한 앞으로 20년간 (2036 년까지) 다양한 구성요소의 수준을 정량화할 수 있는 지속 가능성 개념에 대한 강한 요구가 있음은 주지의 사실이다. 지속 가능성의 새로운 패러다임은 에너지, 경제 및 환경의 전통적인 구성 요소로 구성된다. 더불어 지속 가능성은 안전, 보안 및 세계화(globalization)를 다루어야 한다. 미래의 지속 가능성 개념은 이러한 6가지 구성 요소 모두를 하나의 기능으로 정량적으로 통합할 것이다. 특히 이 작업에 대한 강력한 리더십은 화학 공정 산업에서 절대적으로 부족한 현실이기에, 이러한 기능의 통합과 특화된 교육 및 훈련에 대해 한국의 사례와 해외에서의 글로벌 응용 프로그램에 대란 논의를 통해 본 발표는 향후의 발전방향과 비전에 대해 논의하고자 한다.

Owing to the increase of chemical usage, ordinary people are frequently exposed to chemicals and chemical products. Thus, demand on emergency response to chemical accidents is rapidly increasing. Also, as new chemicals continue to be introduced to the market, information system on chemicals need to be consistently updated. Under the circumstances, the MOE(Ministry of Environment) has established a comprehensive 24-hour web-based CEIS(Chemical accident Emergency response Information System) which contains more various material information for wider range of users from governmental organization to the general public.

Objectives: Chemical accidents cause extensive human and environmental damage. Therefore, it is important to prepare measures to prevent their recurrence and minimize future damage through accident investigation. To this end, it is necessary to identify the accident occurrence process and analyze the extent of damage. In this study, the development process and damage range of actual chemical leakage accidents were analyzed using CFD. Methods: For application to actual chemical leakage accidents using FLACS codes specialized for chemical dispersion simulation among CFD codes, release rate calculation and 3D geometry were created, and scenarios for simulation were derived. Results: The development process of the accident and the dispersion behavior of materials were analyzed considering the influencing factors at the time of the accident. In addition, to confirm the validity of the results, we compared the results of the actual damage impact investigation and the simulation analysis results. As a result, both showed similar damage impact ranges. Conclusions: The FLACS code allows the detailed analysis of the simulated dispersion process and concentration of substances similar to real ones. Therefore, it is judged that the analysis method using CFD simulation can be usefully applied as a chemical accident investigation technique.

화학물질은 제조 사용 폐기 등 전 과정에서 다양한 경로를 통하여 인체와 환경에 치명적 재난을 가져올 잠재력을 가지고 있으므로 사업장 내부뿐만 아니라 Off-site의 영향까지 사전 예측하여 관리하는 종합적인 화학사고 예방제도의 도입과 관련 연구 필요성이 제기되고 있다. 즉 기존의 단면적, 정성적이며 기술적 측면, 인허가를 위한 예방 중심, 설비 중심의 화학사고 대응 방식에서 포괄적, 적극적, 생산적, 정량적이며, 인문 사회학적, 다차원적 방식으로 확대가 반드시 이루어져야 한다.

Purpose: In this study, the characteristics of hazardous chemical transport vehicle accidents during the last six years from 2014 to 2019 was analyzed. This study is to prevent chemical transport accidents. Method: Using statistics from the Ministry of Environment, chemical transport vehicle accidents were classified into accident type, accident cause and vehicle type. Result: Of the total 506 cases chemical accidents, 105 cases were caused by transport vehicle. More than 20 percent of total accidents were reported. Most of the accidents were caused by spill·leak. The main causes of the accident were traffic accidents(49 cases) and management negligence(29 cases). This was more than 74% of all transport vehicle accidents. By vehicle type, 57 cases(54%) were most common in tank lorries, followed by trucks (39 cases, 37%) and trailers (9 cases, 9%). Conclusion: In order to prevent accident of transport vehicle, thorough inspection of the transport vehicle is required and safe operation of the driver. In addition, the government needs to expand real-time monitoring of transport vehicles and comprehensively manage different systems by the relevant ministries.

After the hydrogen fluoride leak in Gumi in 2012, the government has been systemizing the disaster management system, such as responding to and managing chemical accidents. In particular, the Ministry of the Interior and Safety (MOIS) is in charge of evacuation of residents following chemical accidents based on the Framework Act on Management of Disaster and Safety. In this study, an application plan was presented to support and utilize the decision-making support for evacuation of residents after a chemical accident using the chemical accident investigation equipment of the National Disaster Management Research Institute (NDMI). In the equipment operation system for scientific information collection due to chemical accidents, the roles and purpose of use of long/short distance measurement equipment were presented according to regular and emergency situations. Using the data acquired through long/short distance measurement equipment, it can be used as basic data for resident evacuation decision-making by monitoring whether chemicals are detected in an emergency and managing data on detected substances by company in a regular situation. As a result of measuring chemical substances in order to verify on-site usability by equipment only for the regular operation system, it was confirmed that real-time detection of chemical substances is possible with long distance measuring equipment. In addition, it was confirmed that it was necessary to check the measurable distance and range of the equipment in the future. In the case of short distance measurement equipment, hydrocarbon-based substances were mainly detected, and it was confirmed that it was measured at a higher level in Ulsan-Mipo National Industrial Complex than in Onsan National Industrial Complex. It is expected that it can be used as basic data to support decision-making in the event of chemical accidents through continuous data construction in the future.

In the trend of increasing awareness of chemical accidents, hazardous chemical transport vehicle accidents are occurring every year. In this study, we analyzed improvement of accident prevention and countermeasures through statistical analysis of hazardous chemical transport vehicle accidents. A total of 383 chemical accidents between January 2014 and December 2017 were analyzed. During this period, number of transportation accidents was 83 cases, accounting for 21.67% of total chemical accidents. In the current system, despite the direct handling of hazardous chemical, it is out of regulation of damage prediction unlike the workplace. In order to effectively respond to actual accident, information on damage prediction is required and should be shared with related ministry. And it should be developed to real-time monitoring of hazardous chemical transport vehicle through integrated control tower.
