Abstract

In this research, the fire mistaken dispatch records for the past 11 years have been analyzed by using a statistic technique. Fire mistaken dispatch occurred yearly average $48,371{\pm}5,763$ time at 95 % confidence level. This is 1.2 times more than the dispatch for extinguishing the fire. Fire mistaken dispatch has been increased mainly by malfunctioning alarm among other various reasons and the reason of mistaken dispatch is different depending on the population of the region. In big cities, the burning smell accounts for the most of mistaken dispatch but in rural areas, the garbage incineration is the major reason for mistaken dispatch. As a result of calculating the mean time between fire mistaken dispatches (MTBFmd) by region, MTBFmd of Daejeon is 20.61 hr/time and its reliability is 95.26 % at t=1 hr. On the other hand, the MTBFmd of Gyeonggi is 0.58 hr/time and its reliability is 17.91 % at t=1 hr.

과거 11년간의 국내 화재 오인출동 자료를 통계적 기법을 활용하여 분석하였다. 오인출동은 95 % 신뢰수준에서 연평균 $48,371{\pm}5,763$건이 발생하였고, 이는 화재진압을 위한 출동보다 약 1.2배 높은 수준이다. 여러 원인 중 경보오동작에 의한 오인출동이 증가하고 있으며, 오인출동의 원인은 시 도별 인구수에 따라 다른 양상을 보이는데 대도시에서는 타는 냄새에 의한 오인출동이 많은 반면 농어촌에서는 쓰레기 소각에 의한 오인출동이 많았다. 지역별 평균오인출동간격을 계산한 결과 대전은 20.61 hr/회로 t=1 hr 일 때 95.26 %의 신뢰도를 보이는 반면, 경기도의 경우 평균오인출동간격은 0.58 hr/회로 t=1 hr 일 때 신뢰도가 17.91 %에 불과하였다.
