The chemical industry treats a huge quantity of hazardous and harmful flammable liquids, combustible gases and toxic materials. Therefore, there is a high potential for fires, conflagrations, explosions and toxic leaks. To minimize the possibility of such hazards, the Korean government has been enforcing an EPP (Emergency Preparedness Plan) in accordance with the Toxic Chemicals Controls Act since 1996. However, 70% of the targeted small and medium-sized enterprises are struggling with the independent implementation of EPP, and 30% of the EPP grades being used are not amenable to approval and further application. As a result, we have developed a web-based emergency preparedness plan system. The main purpose of the program is to provide a safety management system to each facility in order to enable accidents to be prevented and accidents to be immediately controlled. The program also helps government or related agencies to control a number of accidents that occur in small companies throughout the entire country.
