Abstract

The number of large and complex buildings is growing and they are usually concentrated in metropolitan cities. There is a possibility in such buildings that a small accident can expand to a massive disaster since their scale and complexity. To deal with this issue, a research on gas sensors which can detect multiple gases and early-warning systems has been conducted. Proper criteria or standards are necessary for effective application and operation of such sensor-based disaster monitoring system. In this study, we have proposed the alarm criteria of concentration of hazardous gases for the detection and the alarm release. For each alarm level, systematic disaster response plans consist of responsive actions and information delivery have been prepared. These disaster monitoring criteria can help the detection of hazardous gas-related disaster in the early stage of accident and the provision of appropriate emergency responses.

대도시 내에 밀집하여 증가하고 있는 대형 복합 건축물은 그 규모와 복잡성으로 인해 유해가스 관련 사고발생시 대형 재난으로의 확대 가능성이 상존한다. 이에 대한 대응책으로, 다종의 유해가스를 감지하는 복합 가스 센서와 이로부터 수집한 정보를 활용한 조기 경보 시스템이 연구되고 있다. 이와 같은 센서 기반 재난 전조 감시 시스템의 효과적인 적용과 운영을 위해서는 적합한 기준이 먼저 마련되어야 한다. 본 연구에서는 유해가스의 감지와 조기 경보 발령을 위한 경보 기준 농도를 제시하고, 각 경보 단계별로 대응 활동과 정보 전파 등 재난 대응 체계를 제안하였다. 재난 감시 기준을 통해 유해가스 관련사고 발생 시 조기에 위험을 감지하여 사고의 경과에 따라 효과적인 대응을 이끌어 낼 수 있다.
