ABSTRACT

The number of chemical accidents involving nitric acid continues has increased for the last three years. As nitric acid is strongly toxic, an appropriate dike surrounding a storage tank must be installed to prevent the release of toxic chemicals. In installing a dike, it is important to consider the capacity of a storage tank and minimize the surface area within a dike. By using Off-site Risk Assessment modeling program (KORA), this study conducted an evaluation of EPRG-2 dispersion distance from dikes that are installed in compliance with the Dangerous Substance Control Act and the Chemicals Control Act. The results indicate that the requirement of maintaining a distance of 1.5 m or more between a dike and a tank is effective in reducing the possible affected areas. Also, it is proposed to establish uniform standards for dike facilities through collaboration among the governmental ministries.
