The systems in Korea regarding manufacture, storage, transport and use of hazardous materials are regulated by the related laws and ordinances. The number of accident from hazardous materials has recently decreased but the size of accident has increased according to the hazardous substances are greatly consumed and delivered. The results of analysis showed that most of accidents are caused by human problems and occurred frequently at unauthorized facilities. It is suggested that workers should be trained more and the strict regulation on unauthorized facilities is needed to reduce the accidents caused by hazardous materials.

Chemical products have had an favorable influence on our everyday life, and contributed very much to the development of human culture. According to the rapid change of industry and the development of scientific technique the using chemical products are increasing more and more. Chemical products can have any hazardous property such as flammability or explosiveness. There are occurring many accidents in the international trade due to the different classification and labelling of chemicals produced in various countries. The main purpose of this work is the development of global standard test methods for the chemicals, and the classification and labelling in building block approach by means of the basic technical data. Oxidizing solids, combustible solids, spontaneously combustible materials, water-prohibitive materials, flammable liquids, self-reactive materials and oxidizing liquids have been tested. The results have been classified according to the hazard material safety regulation and the UN regulation, and summarized in a data-base.

Many countries are managing the transportation of hazardous materials under the specific provisions especially, as well as use, storage and management, because of their high risks. For the purpose of the revision of rail safety law for the safe transportation of hazardous materials, amount and kind of hazardous materials transported by rail in Korea are analysed and the standards of classification of hazardous materials are compared in domestic and abroad. There are lots of benefits for national rail safety law to implement an international law because our country's geographic location is convenient to connect the continent and to across the border. It is suggested that implementing a classification and test methods of hazardous materials enable to use internationally for the preparation of rail transportation to be increased.

Recently, there are so many studies related safety of railway vehicle. But these studies are focused on the passenger car, metro system and high speed train. However, the leakage of hazardous materials may contaminate the environment and cause terrible damage to the ecology, even the human and properties. And so, Safety and security have been already established in many countries, currently they are investing lots of money on the development of technology to prevent accidents. Therefore it is necessary to make a systematic plan and develop safety specifications. In this study, we compared between domestic and international general oil tank car safety regulations for the hazardous materials, and prepare the basic for the making of systematic safety plans and safety regulations for the transport of hazardous materials by tank car.

Objectives: The major objectives of this study are to review the issues surrounding trade secret claims in the Chemicals Control Act and Amendment on Occupational Safety and Health Act(1917-227) and to propose a way of improving the reliability of chemical information in MSDSs, labels and National Chemical Survey results. Materials: To review the issues on trade secret claims, we made an analysis frame which was divided into three steps: Value and Problem Recognition; New Regulation Design; and Enforcement and Amendment. We then compared Korean issues with issues from the United States' Hazard Communication Standard and Emergency Planning & Community Right-to-Know Act, Canada's Workplace Hazardous Materials Information System and Hazardous Materials Information Review Act and the European Union's Regulation on Classification, Labelling and Packaging of substances and Mixtures. Results: The stage of right-to-know development in Korea has passed the Value and Problem Recognition phase, so efforts are needed to elaborately design new regulation. Conclusions: We recommend two ways to improve right-to-know in Korea. First, strict examination of the quality of documents for trade secret claims is very important. Second, trade secrets should be limited to less-hazardous substances.

Objective: This study inspected incident cases, legal control levels, and GHS(Globally Harmonized System of Classification and Labeling of Chemicals) classification results of strong acids such as hydrogen fluoride, hydrogen chloride, nitric acid, and sulfuric acid, which have been responsible for many recent chemical accidents. As a result, it is deemed necessary for legal control levels of these strong acids to be revised and GHS classification be managed nation-wide. Methods: This study inspected incident cases and legal control levels for strong acids such as hydrogen fluoride, hydrogen chloride, nitric acid, and sulfuric acid. The study analyzed and compared chemical information status and GHS classification results. Results: There were 76 domestic incidents involving strongly acidic hazardous materials over the five years between 2007 and 2011. They include 37 leakage incidents(46.7%) within a workplace, 30 leakage incidents(39.5%) during transportation, and nine leakage incidents(13.8%) following an explosion. The strongly acidic materials in question are defined and controlled as toxic chemicals according to the classes of Substances Requiring Preparation for Accidents, Managed Hazardous Substance, Hazardous Chemical(corrosive) as set forth under the Enforcement Decree of the Toxic Chemicals Control Act and Rules on Occupational Safety and Health Standards of Occupational Safety and Health Act. Among them, nitric acid is solely controlled as a class 6 hazardous material, oxidizing liquid, under the Hazardous Chemicals Control Act. The classification results of the EU ECHA(European Chemicals Agency) CLP(Commission Regulation(EC) No. 790/2009 of 10 August 2009, for the purposes of its adaptation to technical and scientific progress, Regulation(EC) No 1272/2008 of the European Parliament and of the Council on classification, labeling and packaging of substances and mixtures) and NIER (National Institute of Environmental Research) are almost identical for the three chemicals, with the exception of sulfuric acid. Much of the classification information of NITE (National Institute of Technology and Evaluation) and KOSHA(Korea Occupational Safety and Health Agency, KOSHA) is the same. NIER provides 12(41.4%) out of 29 classifications, as does KOSHA.

Objectives: This study was conducted in order to evaluate the limitations of the regulations on the safety and health standards for special management materials(SMM) under the Industrial Safety and Health Act in Korea. Methods: Hazardous chemicals management systems in Germany(Hazardous Substances Ordinance), the UK(Control of Substances Hazardous to Health Regulations), Japan(Ordinance on Prevention of Hazards due to Specified Chemical Substances) and Korea(Regulation of Occupational Safety and Health Standards, ROSHS) were investigated and compared in terms of 14 items. Results: Among the 14 items, we eventually found seven items which should be amended: 1) definition and scope, 2) general duties clause, 3) principles of management, 4) preventive measures, 5) control measures, 6) risk assessment, and 7) record keeping. The principal limitations of Korean regulations in comparison with those of other countries were that there were no preventive measures such as substitution, and no principles of good practices for the control of exposure to SMM. In terms of control measures, there were no regulations on suitable workplace design, reducing the number of exposed workers, reducing the level and duration of exposure, and reducing the quantity of hazardous substances in ROSHS. Conclusions: Based on the results of this study, ROSHS should be complemented with preventive measures and the principles of management related to SMM. According to the suggestions, an employer who deals with SMM should preferably consider the possibility of substitution and perform substitution so far as is reasonably practicable.

In this study, we investigated the main characteristics of off-gas generated from melting process and off-gas treatment system operation example to provide some primary data for commercial vitrification facility design. The purpose of vitrification facility operation is to treat hazardous materials in the radioactive wastes and harmful off-gas containing a variety of chemical species generated in the glass melting process. Constructing and operating vitrification facility essentially need to be licensed through safety analysis; it is very important to treat radionuclide and hazardous materials below the legal environment emissions regulation level. We must accurately understand the characteristics of off-gas and apply an appropriate off-gas treatment process accordingly. Thus, to design the appropriate off-gas treatment there must be a wide range of elements taken into account such as characteristics of waste and melter, regulation guidance of off-gas, characteristics of generated off-gas and off-gas treatment system performance assessment.
