Abstract

The domestic gas detector installation standards applied to gas detectors, which are one of the facilities that can prevent accidents such as fire, explosion, and leakage that can cause serious industrial accidents, do not take into account the behavioral characteristics of hazardous chemicals in the atmosphere. It can be seen that the technical basis is insufficient because the standard is applied. Therefore, in this study, the size of the leak hole for each facility mainly used in chemical plants and the diffusion distance according to the concentration of interest of hazardous chemicals were analyzed, and based on this, the optimal installation distance for gas detectors for each material was suggested. Using the method presented in this study, more economical and effective gas detector installation can be expected, and furthermore, it can be expected to help prevent serious industrial accidents.

중대산업사고를 일으킬 수 있는 화재, 폭발, 누출과 같은 사고를 사전에 예방할 수 있는 설비 중 하나인 가스감지기에 적용하고 있는 국내 가스감지기 설치 기준은 유해화학물질의 대기 중 거동 특성을 고려하지 않은 설치 기준을 적용하고 있어 그 기술적 근거가 부족하다고 볼 수 있다. 따라서 본 연구에서는 화학공장에서 주로 사용하는 설비별 누출공의 크기와 유해화학물질의 관심 농도에 따른 확산 거리를 분석, 이를 토대로 하여 물질 별 가스감지기 최적 설치거리를 제시하였다. 본 연구에서 제시한 방법을 이용하여 보다 경제적이고 효과적인 가스감지기 설치를 기대할 수 있으며, 나아가 중대산업사고를 예방하는데 도움이 될 것으로 기대할 수 있다.
