산업재해를 방지하고 사고시에 적절한 대책을 마련하기 위해서는 각 위험설비와 위험물질로부터 발생할 수 있는 사고유형, 발생가능성 및 피해를 객관적인 단위로 평가하는 정략적 위험성평가가 수행되어야 하며, 이러한 정량적 평가를 수행하기 위해서는 신뢰도 데이터베이스가 필수적이다. 따라서, 본 연구에서는 사업장에서 설비 및 기기에 대한 신뢰도 데이터베이스를 구축하기 위해서 신뢰도 데이터 수집 및 분석체계구축, 자료 입력 및 분석 소프트웨어를 개발하여 구축된 자료를 토대로 정량적 위험성 평가에 활용할 수 있는 방법론을 제시하였다.

The bottom of dikes must be kept impermeable to control hazardous chemicals spilled from storage tanks. Currently, insufficient related chemical control laws lead to a possibility to spread through the bottom. Generally, due to the high cost of installation and periodical maintenance, many businesses prefer to install the bottom with general concrete. But, since the impermeability of concrete is dependent on the kind of materials and chemical reaction, all concrete cannot be considered as impermeable material. Thus, it is necessary to make the installation standards of the dike bottom clear in order to avoid the argument over the impermeability and prevent the chemical accident. This study has suggested the standards of impermeable concrete by conducting 7-day exposure test to crude oil with the pilot dikes. The results have showed that the standards have the better impermeable performance compared with the germany standard, which have been penetrated at the maximum penetration depth of 1.9 cm. This study is expected to contribute to both the risk reduction of penetrating into the bottom and the cost reduction of spending to make the bottom of dikes impermeable.

최근 지속 가능한 개발과 유해화학물질의 국제적 규제를 목표로 한 바젤협약, Agenda 21, POP 의정서 등 여러종류의 국제협약이 진행되고 있으며, 환경규제는 점차 무역규제 형태로 나타날 전망이다. 특히, 화학산업의 경우 이러한 국제협약에 우선적으로 큰 영향을 받을 것이다. 따라서 국내외 환경규제에 대비하기 위하여 오염원에 대한 원천적인 제거와 오염물질을 감량시킬 수 있는 청정기술의 개발 및 도입이 시급하다. 환경친화적 기술개발을 바탕으로 국제 경쟁력의 우위를 유지 또는 선점하기 위하여 우리나라도 환경정책을 선진화하고 환경기술 개발을 촉진시켜 특히 화학산업의 경쟁력을 꾸준히 높여나가야 할 것이다. 본 연구에서는 화학산업과 관련된 국내외 환경규제와 유해화학물질의 관리현황을 살펴보고 화학산업의 발전을 위한 청정기술 개발의 방향을 고찰하고자 한다.

Although it is suggested that risk -based management plan is needed to manage air pollution effectively, we have no resources enough to evaluate all aspects of substances and set priorities. So we need to develop a logical and easy risk-based priority setting method. However, it if impossible that only one generic system that is consistent with all the use is developed. In this study, we proposed a human health risk based priority-setting method for hazardous air pollutants, and ranked priorities for this method. First of all, after investigating previous chemical ranking and scoring systems, we chose appropriate indicators and logics to goal of this study and made a chemical priority ranking method using these. As results, final scores in priority ranking method were derived for 25 substances, and ethylene oxide, acrylonitrile and vinyl chloride were included in high ranks. In addition, same substances were highly ranked when using default values like when using no default, but the scores of hydrofluoric acid and ryan and compounds were sensitive to default values. This study could be important that priorities were set including toxicity type and quality and local inherent exposure conditions and we can set area-specific management guidelines and survey plans as a screening tool.

Thermal behavior of bromphenols was investigated by direct pyrolysis at high temperature. The thermal degradation products formed by the pyrolysis of mono-bromophenols (o-, m-, and p-) were identified by gas chromatography-mass spectrometry. During the pyrolysis reactions, several kinds of dioxins and furans were produced, and the relative ratio of pyro-products was dependent on the substituted position of bromine in phenolic structure due to the effect of symmetry and steric hindrance. The formation of dioxins can be explained by the phenoxy radical addition and Br atom elimination at an ortho-carbon site on phenolic structure. On the other hand, the formation of furans can be explained by the ortho-ortho carbon coupling of phenoxy radicals at unsubstituted sites to form o, o'-dihydroxydiphenyl intermediate via its keto-tautomer, followed by $H_2O$ elimination. The pyrolysis temperature has also a substantial effect on the dimerized products quantities but little effect on the type of pyro-products. Moreover, the formation mechanism of pyro-products was suggested on the basis of products identified.

유해화학물질 누출사고 시 피해 예상지역의 주민안전 확보를 위해 국내에서는 캐나다의 ERG를 기반으로 한 방호활동거리를 활용하고 있다. 그러나 국가별 지형적인 특성이나 기상조건 등이 상이하여 신뢰성 있는 대응에는 한계를 보여 왔다. 본 연구에서는 국내 특정 석유화학공단을 대상으로 지형자료, 기상조건 등을 반영한 AERMOD 모델링 분석을 통해 방호활동거리가 계절별, 지형별로 다소 차이가 있음을 알 수 있었다.

Objectives: To ensure that employers handling petroleum compounds understand whether petroleum-based UVCB (unknown or variable composition, complex reaction products, or biological materials) substances contain hazardous substances and comply with the Occupational Safety and Health Act, petroleum-based UVCB substances were analyzed and the results from samples were compared with MSDS (Material Safety Data Sheet) contents. Methods: Twenty-one petroleum samples were analyzed using GC-MS (Gas Chromatography-Mass Spectrometry), targeting ten volatile organic compounds regulated by the Occupational Safety and Health Act. Results: The target chemicals were detected in 13 out of 21 samples. All 13 samples were in the naphtha (low boiling point naphthas (gasolines)) group. There were also naphtha group samples containing 2% benzene. Some naphtha samples used as solvents contained about 1% benzene. Conclusions: This study shows that naphtha group petroleum substances contain hazardous chemicals in many cases. In particular, if benzene, n-hexane, and toluene with low occupational exposure limits are contained above the limit concentration. Such information should be delivered in the article on MSDS legal regulations.

The significance of gas sensors has been emphasized in various industries and applications, owing to the growing significance of environmental, social, and governance (ESG) management in corporate operations. In particular, the monitoring of hazardous gas leakages and detection of fugitive emissions have recently garnered significant attention across several industrial sectors. As industrial workplaces evolve to ensure the safety of their working environments and reduce greenhouse gas emissions, the demand for high-performance gas sensors in industrial sectors dealing with toxic substances is on the rise. However, conventional gas-sensing systems have limitations in monitoring fugitive gas leakages at both critical and subcritical concentrations in complex environments. To overcome these difficulties, recent studies in the field of gas sensors have employed techniques such as mobile robotic olfaction, remote optical sensing, chemical grid sensing, and remote acoustic sensing. This review highlights the significant progress made in various technologies that have enabled accurate and real-time mapping of gas distribution and localization of hazardous gas sources. These recent advancements in gas-sensing technology have shed light on the future role of gas-detection systems in industrial safety.

Recently, the use of hazardous chemicals has been continuously increasing. Therefore, the international trade volume is growing and chemical accidents have increased. Nowadays, the safety awareness of the public has increased. As a result, the management and supervision of hazardous chemicals have been strengthened. However, the port policy of Korea has focused on increasing the volume of cargo through facility development. Thus, the port management of hazardous chemicals has been relatively neglected. For national economic growth and society, the port management of hazardous chemicals should be considered to efficiently ensure safety and economic growth. Therefore, this study assumed scenarios where hazardous materials were moved in a dangerous container, not only on appropriate wharfs but also in ports that were close to a big city. The BTX substances were selected among the toxic chemicals with large import and export volumes, and the risk distance and damage effects were predicted using various risk assessment programs. It is expected that this could be used to improve a port safety management system and could be utilized to determine the safety distance in case of an accident.
