The emergency response modeling system CARIS has been developed at CCSM (Center for Chemical Safety Management), NIER (National Institute of Environmental Research) to track and predict dispersion of hazardous chemicals for the environmental decision support in case of accidents at chemical or petroleum companies in Korea. The main objective of CARIS is to support making decision by rapidly providing the key information on the efficient emergency response of hazardous chemical accidents for effective approaches to risk management. In particular, the integrated modeling system in CARIS consisting of a real-time numerical weather forecasting model and air pollution dispersion model is supplemented for the diffusion forecasts of hazardous chemicals, covering a wide range of scales and applications for atmospheric information. In this paper, we introduced the overview of components of CARIS and described the operational modeling system and its configurations of coupling/integration in CARIS. Some examples of the operational modeling system is presented and discussed for the real-time risk assessments of hazardous chemicals.

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.

It is not an exaggeration to say that modern chemicals take a leading place in our life, and people live with the chemicals, having a huge impact on their daily life. The chemical industry in South Korea, ranked seventh in the world, is one of the key industries that are forming greater part of Korean economy. The actual state of the chemical industries, however, is that over 14 tons of hazardous chemicals are being discharged annually and threaten people's lives with a lack of knowledge of its potential danger. In this way, not only beneficial to us, some of these substances, All chemicals, but also present a threat fundamentally our living environment to hazards to human health and the environment, accidents such chemicals, unlike accidents general understanding the scale of damage and propagation velocity has a complex very difficult risk profile, that can occur during deployment of an accident type is also very diverse. Is the actual situation of public concern against harmful chemicals management's is amplified by the chemical accident in the wake such accidents, government and corporate and reactive system and management system prior to the chemical accident the need for communication to exchange ideas with each other between residents, providing information is important. Therefore, the government departments and corporations, which manage variety of chemicals, ought to contribute toward a development of national security by rigid control over the Hazardous chemicals.

With a rapid growth of domestic industry in korea, now about 25,000 kinds of chemicals are being distributed, and it has been known that just about 15% of them has toxic substances. Recently, South Koreans have an anxiety about the stability and accidents of chemicals because chemical accidents like Gumi hydrofluoric acid accident have occurred. The U.S. has adopted the systems like EPCRA (Emergency Planning and Community Right-to-Know Act), TRI (Toxic Release Inventory) and TSCA (Toxic Substances Control Act), and is also managing the hazardous chemicals by providing the information about them to its people and site workers. Japan's Ministry of Health, Labor and Welfare also has adopted J-CHECK system and is implementing it to let Japanese people know the information of safety of chemicals about REACH. However, the Korean government has a difficult situation to mediate the different idea with the Korean industry to make lower statute of Pre-legislation registration & evaluation of chemicals that will be implemented and Chemical Material Control Association that is being implemented. Especially city and country areas located in the industrial areas need political improvement focusing on vulnerable area through the check about current situation of hazardous chemicals of jurisdiction and management method, but the information about the management situation of small scale work places is insufficient. Therefore this study set up the urgent management area in Ansan Smart Hub through NFPA code according to the types of accident and dander characteristics of each chemical being used in the companies that have less than 50 workers and deal with chemicals located in Ansan Smart Hub in Gyeonggi-do.

Objectives: This study was conducted in order to ascertain the important factors for SMEs in managing the risks of chemicals and to suggest a government role in strengthening the responsibility of small and medium enterprises(SMEs) as employers. Methods: About 100 enterprises were surveyed in Incheon. A questionnaire for employers and walk-through surveys by occupational hygienists were performed at each enterprise. Results: The results showed that most employers thought chemicals were not hazardous but chemical management was needed. When employers determine how to manage chemicals, they rely heavily on personal experience and rather less on information from the government or experts. However, if employers think the chemicals are hazardous, they do more to manage the chemicals. Conclusions: When employers think chemicals are hazardous, risk assessment would be an effective tool to control chemical hazards in SMEs. Employers' position on chemical hazards is very important. Since the government is the initiator, it is the government who develops messages for SMEs, such as "Chemicals are hazardous and management can reduce the risk of chemicals." Governmental messages can play an invaluable role in strengthening the responsibility of SME employers to manage chemical hazards.

Chemical accidents are increasing day by day as the industry develops. To prevent such chemical accidents, Korea enacted the Chemicals Control Act. Through these laws, systematic management of chemical substances began. There are various positions in the companies. hazardous chemical supervisors, equipment and technical human, operators and employees. Chemicals-related education for each position should be provided. As a result of the survey, hazardous chemical supervisors and equipment and technical human liked the overall content of the Chemicals Control Act and the education subject on safety management standards for facilities. Conversely, the operators liked the course on how to wear personal protective equipment. The employees preferred subjects such as classification of chemical substances and prevention of chemical accidents. Currently, various modular textbooks are widely available. Rather than general education, it is necessary to select and provide customized subjects that are preferred and interested according to the position. Then it will be more effective in understanding harzardous chemical substances and in preventing chemical accidents.
