국내에서 다양한 규모와 종류의 화학사고가 지속 발생 중이며 이 중 초동대응 실패로 피해가 확산되는 경우도 발생하면서 이에 따른 화학사고 대응능력 향상에 대한 요구가 생기게 되었다. 그러나 이는 코로나 이전의 상황이며 2020년 이후에는 코로나 19로 인한 사회 여러 분야의 변화로 새로운 개념과 방법으로서 화학사고 대비와 안전에 있어 중요하게 고려할 사항이 생기게 되었다. 화학사고와 같은 특수 상황에 대비하여, 국가적으로 코로나 19 상황 하에서의 재난의료대응 인력에 대한 해당 재난 유형에 대한 교육훈련 프로그램 및 정책이 제공되어야 하며, 재난의료대응기관에서는 현장구조자 및 응급의료진 등 재난의료대응 전문 인력의 양성을 위한 코로나 19와 같은 신종 감염병을 대비한 상황 하에서의 지침 마련, 시스템 보완, 사전 교육이 시행되어야 한다.

This study the effect of pyrolysis products ABC dry chemical and of monoammonium phosphate on wood surface. When the pyrolysis product was removed from the wood surface, monoammonium phosphate was removed due to the high viscosity of the transparent pyrolysis product, but the ABC dry chemical was removed in a lump form. Thermal analysis showed that the pyrolysis characteristics of each sample were similar but the weight of pyrolysis residue was 55.9% for ABC dry chemical and 25.2% for monoammonium phosphate. The additives added to the ABC dry chemical also affect the weight of the pyrolysis residue and the fire protection effect of metaphosphoric acid.

Natech risk is a type of complex disasters that natural hazards trigger technological disaster or industrial accidents. Research on Natech risk has been started from the mid-1990s in European countries and the Unites States, and drawn much more attention after the Fukushima nuclear accident caused by the 2011 East Japan earthquake. While early studies on Natech risk have focused on the causal natural hazards and possibility to occur, and the resulting spill of hazardous materials from the perspective of science and engineering, the recent research interests lie on effective Natech risk management. Especially, emphasizing the difference of Natech risk management from traditional disaster management, issues of uncertainty management, integration between natural disaster and technological disaster, and responsibility, has been drawn attention. In Korea, Natech risk has not been introduced as a research topic. Although some regulatory improvements have been made in nuclear safety and chemical Substance management after the Fukushima disaster, the potential impact of natural hazards in these areas has not been considered yet. It is necessary to raise the issues of Natech risk management in research and policy areas through active discussion and interdisciplinary approaches.

In Chemical, Biological, Radiological and Nuclear (CBRN) disaster, integrated and optimized equipment package including stretcher, isolation unit, patient monitoring and treatment equipment is essential to achieve proper treatment and prevent secondary contamination. The purpose of this study was to evaluate the efficiency and ease of use of integrated CBRN disaster equipment package for disaster medical response. This study was a randomized crossover study using a manikin simulation for emergency medical technitian (EMT). All participants used the existing devices and prototype of integrated CBRN disaster equipment package alternately. Efficiency was measured by time from vital sign change to detection or treatment application. Ease was use was measured by questionnaires for each patient monitor, stretcher care and isolation unit. 12 EMTs were enrolled. hypoxia-detection time of integrated equipment group was significantly shorter than existing equipment group (4.9 s (3.8-3.9) vs 3.5 s (2.5-3.9), p < 0.05). There was decreasing tendency of ECG change detection and facial mask oxygen supply but no statistical significance was observed. Overall satisfaction of patient monitoring device in integrated equipment group was significantly higher than existing devices (4(3.5-5) vs 3(3-3), p < 0.05). The use of integrated CBRN disaster equipment package shortened the hypoxia detection time and improved usability of vital sign monitor compared to existing devices.

Flammable liquids residues in fire debris and pyrolysis products of flammable materials were analyzed by using Gas detecting tube, Gas Chromatograph/Mass Spectrometers (GC/MS), and Pyrolyzer. Comparison studies between chemical components detected in debris fired with and without Flammable liquids were performed. Though Flammable liquids were not present in debris, Gas detecting tube colors were also changed. Chemical components produced from conventional combustions were different from those produced from pyrolysis. Due to the difference of the reaction conditions between combustions and pyrolysis, different chemical products were produced. Petrochemical products of PVC wood-linoleum block could produce ignitable chemicals, such as toluene, ethylbenzene, undecane, and dodecane. So, for better fire investigation more consideration of those chemicals will be porformed.

As the domestic chemical industry continues to develop, handling and transportation of chemicals increases every year. Road freight in Korea accounts for more than 90%, and most of the chemical transportation is done through roads. These chemical vehicles can lead to major accidents if accidents occur. Transportation vehicles are likely to cause water pollution and soil pollution, which are factors of environmental damage, as well as traffic accidents that are the primary damage. In this work, we write a scenario for hydrogen chloride gas leakage by setting Banpo IC and Seocho IC sections as research areas, and use the ALOHA program to measure the predicted distance and analyze the time when hydrogen chloride gas reached according to the distance. In addition, risk assessment using population density was carried out for areas of damage caused by time using GIS. This suggests the need for prevention and countermeasures in areas of damage.
