In this study, we drew identification techniques of cigarette fires through the cases analyses of the combustion characteristics, the combustion time, the combustion temperature, the combustion test of smoldering materials and the reappearance experiments of cigarette fires. To initiate fires by cigarette fire, the conditions of oxygen supply, combustible materials must be satisfied. On the other hand, fires were not spreaded easily under the insufficient combustion conditions.

The cigarette holds more than 10 percents of the entire fire accidents despite the number of smokers rapidly decreases every year. The purpose of this study is to examine the ignition characteristics of cigarette by experimentation. This study analyzed the cases of fires inferred that they were caused by cigarette in Incheon during 2006. As the representative ignition materials, corrugated board, gasoline, lacquer thinner, tarpaulin, flexible PVC sheet, and poly ethylene were tested. In this experimentation, the corrugated board was ignited by cigarette. However gasoline, lacquer thinner, tarpaulin, flexible PVC sheet, and poly ethylene were seldom ignited. Meanwhile most fire investigators have argued that oils and tents were ignited by cigarette, but this study experimentally proved that such an argument might be ungrounded.

In order to find out the environment vulnerable to cigarette fire in which smoldering fire grows into flame fire, a cigarette combustion test and numerical analysis were performed using fallen leaves of P. densiflora and Q. variabilis. Tests were repeated five times on 2,304 conditions with four cases of fuel moisture content, six cases of velocity, two cases of cigaret location against direction of the wind, three cases of cigaret location against fallen leaves, two species of thickness of cigaret, two cases of slope conditions and two cases of fragileness of fallen leaves. Cigaret fire's flammability to the fallen leaves was monitored by analyzing heat transfer process using CFD (Computational Fluid Dynamic) under the most optimal condition through an ignition test on 2,304 conditions. The result of a cigaret fire ignition test for fallen leaves, found ignition in 197 conditions out of 2,304 conditions representing 8.6% while 13 conditions representing approximately 0.6% saw ignition across five repeated tests. The result of CFD analysis, the temperature of the bottom of fallen leaves was reached on self-ignition and pilot-ignition temperature.

담뱃불로 인한 화재는 사망과 부상 등 인명피해와 개인적인 재산피해뿐만 아니라 화재진압 비용의 증가와 공동체 재산의 손실, 소방관들의 생명까지 위태롭게 하는 공공적 피해도 크다. 본 조사에서는 최근 5년간(2007-20112)의 통계자료를 통해 본 결과 담배꽁초로 인한 화재가 연평균 6,419 건으로 전체 화재의 13.9%를 차지하고 있으며, 인명피해는 연평균 사망 109 명, 재산피해는 연평균 7,022백만원의 피해가 매년 발생하였다. 따라서 담뱃불 화재의 위험성을 알릴 수 있는 교육체계와 언론매체를 통한 지속적인 홍보 및 대국민 계도가 필요하며, 이로 인하여 담뱃불화재에 대한 피해를 최소화 하여야 할 것으로 판단된다.
