Abstract

다중이용시설중 노래방의 경우 대부분이 지하에 위치하거나 혹은 지상에 있더라도 무창층의 밀실 구조를 가지는 구조적 특성 때문에 화재발생시 연기에 질식될 수 있는 위험성이 매우 크다. 본 연구에서는 노래방의 화재 위험성 분석을 위하여 재건축이 진행중인 지역의 실제 노래방을 대상으로 실규모 화재실험을 수행하였다. 실험결과 화재가 발생된 방의 경우 화재발생후 약 5분후에 산소농도는 13.99% 까지 감소하며, 일산화탄소는 0.58%가 발생하였다. 특히 화재가 발생한 옆 방의 경우 화재발생 약 8분후 일산화탄소가 1%이상으로 측정됨으로써 직접적인 화염의 확산보다 방음재의 불완전연소에 의한 일산화탄소등 유독가스에 의한 질식이 더 위험할 수 있음을 확인하였다. 따라서 밀폐된 노래방 화재시 신속한 초동조치가 없을 경우 3분 정도에 인접 공간으로 치명적인 독성 가스가 도달되어 많은 인명피해를 발생시키게 된다. Karaoke is the structural feature that it is located underground or composed of no window layer secret room even over the ground so that it has quite high risk of airway obstruction due to smoke at the fire. In this study, a real scale fire test was performed for actual karaokes at the zone under reconstruction. The results showed that oxygen concentration of the room at which fire occurred decreased to 13.99% around 5 minutes later, and 0.58% of carbon monoxide was generated. Especially, 0.8% or more of carbon monoxide was measured in the room next to it around 8 minutes after fire occurrence. Thus, it was found that air way obstruction would probably occur due to toxic gas such as carbon monoxide by incomplete combustion of sound proofing material rather than flame spread by fire re-spread. Consequently, fatal toxic smoke reaches the surrounding space in around 3 minutes without quick early measures at the fire of sealed room so that many causalities result.
