오늘날의 산업사회는 새로운 화학물질의 개발과 합성 등으로 화학공업도 대형화, 다양화 되어가고 있으며, 모든 부분에서의 에너지 사용량이 증대하여 가연성물질을 대량으로 수송, 저장하는 기회가 많아짐에 따라 착화원이 존재하지 않음에도 자연발화가 원인이 되어 화재, 폭발을 일으키는 사고가 발생하고 있다. 또한 위험성이 잠재적이기 때문에 소홀하게 다루기 쉬워 큰 피해를 초래하는 경우가 있다. (중략)

화재의 원인과 확산과정을 과학적으로 설명하는 화재 감식분석에 있어 예방과 피해를 최소화하기 위해 화재 감식분석기법은 계속 변화되고 있으며 또한 이에 대한 과제가 증가되고 있는 추세이다. 따라서 본 연구에서는 화재감식에서 기초적이고 필수적인 화재성격판단과 연소흔적 판단, 발화원의 판단에 대해서 서술하고 이에 대한 향후 과제를 제시하였다.

자연발화란 어떤 물질이 공기 중에 노출되어 외부의 화염, 불티, 고온체와의 접촉 등에 의한 출화가 아닌 그 물질 고유의 성질로 스스로 발열반응을 일으키고 온도상승을 일으켜 마침내 발화하는 현상을 말하며 다음과 같은 것이 있다.

The purpose of this study is to check the fire origin and cause of the fire by observing the shape of the flame propagation in air-conditioner indoor unit through the fire tests. We supposed that the flame is spread from the surroundings to the top of the air-conditioner and ignited on top of the air-conditioner with n-heptane. And then repeated this experiment twice under the same conditions. After the ignition, refrigerant filled in air-conditioner and lubricating oil exploded with large explosion and flame having high temperature and pressure belched out rapidly due to bursting refrigerant pipe linked air-conditioner between 734 seconds and 559 seconds. After result of checking the combustion residue we found that almost all of that was lost except a part of the evaporator, motor and metal. The position of short-circuit traces of wiring for the air-conditioner ignited itself is similar to that of fire damage by external flame. Therefore, we verified that it is not certain to determine the ignition cause and point by only the shape of the combustion residues.

The AP/HTPB composite propellant is a common choice for solid rocket propulsion. The externally heated rocket via fires, for instance, can cause the energetic substance to ignite, and this may lead to a thermal runaway event marked by a severe explosion. In order to develop preventive measures to reduce the possibility of such accidents in propulsion systems, we investigate the ignition and initiation properties of AP/HTPB propellant.

Based on the analysis of the actual passenger vehicle fire cases for recent four years (2010~2013), the passenger vehicle fire is increasing annually. Main root cause was analyzed as an electric problem as a 39%. Vehicle fire case by electric problem was mainly caused by use of Non-genuine part. Vehicle fire case by mechanical problem was mainly caused by various oil system maintenance. Vehicle fire case by smoking material was mainly caused by cigarette and disposal lighter. And external fire transition issue and towing mistake fire cases was also confirmed.

Electric mosquito repellent mats can be ignited by damage of cables, partial disconnection, overload. tracking and so on. In this study, we examined the structure of mosquito repellent mat, positive temperature coefficient(PTC) thermistor, used for heating element and phenomenological characteristics of remains, obtained on the scene of fires. After reappearance ignition test of PTC thermistors, we did comparison analysis them. And we could confine that the feature of heating plate and the shape of bursting were same.

Purpose: As corn oil is semi-drying oil, it has more double bonds than non-drying oil and is easier to combine with oxygen. In addition, among the causes of spontaneous ignition, accidents caused by oil-soaked cloths due to oxidative heat are gradually increasing. Therefore, the purpose of this study is to understand the characteristics of spontaneous combustion according to the number of towels and the amount of corn oil at 65℃. Method: After setting the test temperature to 65℃, 25ml, 50ml, 75ml of corn oil per towel was sprayed. The central temperature of the sample rises above the set temperature. It was determined, and when the central temperature of the sample became similar to the set temperature, it was determined as non-igniting. Result: After evenly distributing 25ml of corn oil per towel, as a result of the experiment, 5 towels did not ignite, and 10 and 15 towels ignited. Also, as a result of an experiment using 50ml and 75ml of corn oil per towel, spontaneous ignition occurred when the number of towels was 5, 10, or 15 sheets. Conclusion: Even a small amount can cause a fire if the conditions for spontaneous ignition are met.
