Abstract

In this study, we investigated whether the evacuation time according to the exit installation standards specified in the building code during a food factory fire is compatible with the evacuation time based on the performance-based design specified by the fire department, in order to determine if evacuation safety is ensured. We used the Pathfinder program to confirm the evacuation time, and experimented with three scenarios for exit installation standards towards the outside of the building: 60m, 80m, and 100m. The target building in the experiment corresponded to the building code's exit installation standard of 100m from each dwelling. The experimental results showed tt in the cases of 80m and 100m, ASET exceeded RSET, indicating tt evacuation safety was not ensured, while in the case of 60m, evacuation safety was maintained. Through this study, it was confirmed tt even when the exit installation standards towards the outside of the building are met, evacuation safety may not be guaranteed.

이 연구는 식품공장에서 건축법 제39조(건축물 바깥쪽으로의 출구 설치), 건축물의 피난·방화구조 등의 기준에 관한 규칙 제11조(건축물 바깥쪽으로의 출구의 설치기준)을 기준에 따라 각 거실로부터 60m, 80m, 100m거리에 출구를 설치했을 때 소방청에서 명시한 소방청 고시 행정규칙인 '소방시설 등의 성능위주설계 방법 및 기준'의 [별표 1]에서 제시하는 화재 및 피난 시뮬레이션의 시나리오 작성 기준 중 W3인 최악의 상황으로 4분(240초)이내에 피난을 성공하여 피난 안전성 평가를 진행하였다. 피난시뮬레이션을 위해 미국 Thunder사의 Pathfinder프로그램을 사용하였다. 본 연구 대상 건축물은 내화구조로 각 거실로부터 100m거리 이내에 출구가 설치되면 건축법에 만족하는 건물이었지만 실험 결과 각 거실로부터 60m거리에 출구가 있을때만 피난 안전성이 지켜졌으며, 80m, 100m거리에 출구를 설치했을 경우 피난안전성이 지켜지지 않고 피난에 실패하는 재실자가 발생하였다. 본 연구에서는 출구 설치기준이 각 거실로부터 100m일 때 비해 60m일 때 피난 소요시간이 47.5%나 줄어들 수 있다는 큰 연구성과를 보여주었다.
