염화수소 누출에 따른 소방계획서 개선방안

This study aims to propose an improvement of fire safety management plans for buildings, such as apartment complexes and schools, within a 10 km radius of industrial complexes. It utilizes an off-site consequence analysis program to reflect the toxic impact on national industrial complexes and surrounding areas. The ALOHA program was utilized to analyze the impact of toxicity due to a hydrogen chloride leak, a hazardous material. The results showed that the area with AEGL-2 and above ranged from 3.1 km to 10 km, the AEGL-3 area ranged from 1.9 km to 7.3 km. The ASET was measured to be between 3 and 24 minutes. Due to the impact of toxicity, it is necessary to prepare fire safety management plans for buildings, such as apartment complexes and schools that are within a 10 km radius from industrial complexes. These safety plans incorporate the hydrogen chloride risk assessment results, ASET, weather conditions, and coordination with the local community.
