Chemicals are essential for modern society, and more than 15 million kinds of chemicals are commercially used all over the world. Among them, the number of kinds of chemicals circulating in Korea reaches approximately 43,000 or above. It was shown that damage and frequency of occurrence of chemical accidents was at a high level according to an increase in the amount of chemicals used and circulated. According to statistical data provided in Chemistry Safety Clearing-house established by National Institute of Chemical Safety, the number of chemical accidents occurring in Korea for the last 10 years (2005~2014) was found to be 297. Among them, the number of spillage accidents was 230, and accounted for 77%. And with regard to substances which caused accidents, it was shown that accidents most frequently occurred due to hydrochloric acid, being followed by sulfuric acid and nitric acid. This study suggested a scheme of reducing damage and analyzing a threat zone when hydrochloric acid spilled for hydrochloric acid storage facility in acid regeneration process where spent acid was regenerated by using as a key raw material the hydrochloric acid that accounted for a high portion among substances which caused chemical accidents. In order to suggest countermeasures for minimizing damage, threat distance according to spillage accident from hydrochloric acid storage facility was analyzed depending on area of pool by using ALOHA 5.4.5 program. Furthermore, threat distance was analyzed by using KORA-ver1.0.0.12 program before․after hydrochloric acid storage facility was sealed tightly. According to the results of analysis, in case of reducing the area of spilled pool from 80 m2 to 27 m2, the threat zone decreased by 83m from ERPG-2(20 ppm) 213 m to 130 m. And it was possible to verify that the threat zone decreased by 139.9 m from ERPG-2 198.6 m to 58.7 m before·after being sealed tightly. When hydrochloric acid storage facility was sealed tightly, it was shown that the threat distance was minimum. However, it is thought proper to minimize the threat distance by minimizing the area of dike considering safety such as facilities and wall corrosion and suffocation due to hydrochloric acid vapor. It is expected that the results of this study will be utilized for minimizing damage to local residents and protected facilities located within the threat distance in case of spillage accident at hydrochloric acid storage facility.
