ABSTRACT

According to the data on chemical accidents for the last three years, chemical accidents involving nitric acid have been continuously increasing in Korea. The proper management to minimize the damage of the accidents is necessary because of a strong toxicity of nitric acid. The previous research suggested the distance of 1.5 m between a dike and a storage tank to reduce the end point of ERPG-2 assuming the maximum spill from a storage tank of nitric acid estimated by the KORA program. However, the distance of 1.5 m was determined merely by focusing on retaining the whole nitric acid spilled from the tank without considering additional safety factors, and needs to be reduced considering that the spilled nitric acid could drain quickly into a waste water treatment plant right after being detected. The findings of this study suggest that the reduced distance of 0.5 m could reduce the end point of ERPG-2 and thus need to be adopted as a standard of dike installation.
