인화성액체는 공장가동에 필요한 연료, 생산과정에서 사용되는 세척제$\cdot$용제, 원료 등 거의 모든 화학공업에서 광범위하게 사용되고 있다. 인화성 액체는 소방법에서 제4류로, 산업안전보건법에서는 인화성물질로, 선박안전법에서는 선적액체 위험물 중 인화성액체 물질로 각각 구분되어 제조, 저장, 취급, 운반, 이송시 지정수량과 저장, 취급방법의 규제 등으로 엄격히 관리되고 있는 실정이다. (중략)

인화성 액체는 소방법상의 4류 위험물로 분류되며 공업용 연료, 세척, 용제 등의 원료로서 그 사용빈도, 취급, 저장되는 양이 타 위험물에 비하여 매우 많을 뿐 아니라 그 종류도 다양하며 화학공업 분야에서 광범위한 사용이 이루어지고 있다. 이러한 대부분의 인화성 액체는 낮은 B.P. 빠른 증발속도, 저인화점의 물리적 특성으로 가연성 증기의 형성이 용이하고 화재 및 폭발의 위험성과 다량의 유독성 증기의 발생 위험이 존재하고 있다. (중략)

화학물질의 분류 및 표시의 국제표준화시스템(GHS)을 조기에 구축하고 국내에 사용하는 화학물질을 보다 안전하게 제조, 저장 및 운송하기 위하여 위험물안전관리법과 GHS시험 방법으로 다양한 인화성액체 시험을 실시하여 이들의 결과에 대한 연관성을 도출하고, 국내 실정에 적합한 국제표준화 시험방법을 선택가능방식(Building Block Approach)으로 제시하고자 한다. 위험물의 80%를 차지하는 인화성액체의 분류에 필요한 시험은 인화점이 가장 중요한 요소지만, 도료류와 같은 혼합물은 가연성액체량과 GHS-연소지속성에 따라 위험물/비위험물로 분류될 수 있다. 도료류는 두 시험의 분류결과가 대부분 비슷하게 나타나 GHS-연소지속성시험을 선택가능방식을 통해 우리나라에 적합하게 도입하는 것이 바람직 할 것으로 보인다.

The neural networks were able to be used by analyze fire source with the optical characteristics of smoke particles. The neural networks were learned the optical characteristics for three types test fire (paper, wood, flammable liquid). These test fires which were adopted in this study were also used to performance test of smoke detector according to UL268. A smoke chamber which was able to detect light extinction and scattering simultaneously was created. The optical characteristics of smoke particles were measured by the smoke chamber. And the results were used to input data for the neural networks. The neural networks distinguished the fire source accurately for paper fire, wood fire or flammable liquid fire. The neural networks distinguished accurately the combined fire source such as paper-wood fire, paper-flammable liquid fire or wood-flammable liquid fire.

Flammable liquids residues in fire debris and pyrolysis products of flammable materials were analyzed by using Gas detecting tube, Gas Chromatograph/Mass Spectrometers (GC/MS), and Pyrolyzer. Comparison studies between chemical components detected in debris fired with and without Flammable liquids were performed. Though Flammable liquids were not present in debris, Gas detecting tube colors were also changed. Chemical components produced from conventional combustions were different from those produced from pyrolysis. Due to the difference of the reaction conditions between combustions and pyrolysis, different chemical products were produced. Petrochemical products of PVC wood-linoleum block could produce ignitable chemicals, such as toluene, ethylbenzene, undecane, and dodecane. So, for better fire investigation more consideration of those chemicals will be porformed.

This study examined the growth characteristics and carbonization pattern when a fire occurs due to a flammable liquid sprinkled on a vinyl floor. When acetone was sprinkled on a floor, the flame reached its peak in approximately 0.2 s after it was ignited. The lower part of the flame showed a laminar pattern while the upper part showed a turbulent pattern. The pattern showed a turbulent pattern and generated white smoke. The combustion completed floor surface showed carbonization of a dim pore pattern. In the case of benzene, an intense flame was formed in approximately 0.6 s after ignition. The flame length was measured to be approximately 50 mm. When the flame became weak, a significant amount of black smoke was generated due to incomplete combustion. The combustion completed floor surface showed carbonization of a pour pattern and splash pattern. In the case of alcohol, an intense flame was formed in approximately 1.1 s after ignition. In addition, the depth of carbonization was significant where the flammable liquid was collected and a trace of carbonization was observed at the boundary of the flow path of the flammable liquid.

With the development of the chemical industry, related accidents frequently occur, and fire and explosion accidents account for a large proportion. In order to prevent fire and explosion accidents, places that handle flammable liquids are classified according to the Korean Industrial Standards (KSC IEC60079-10-1) in accordance with the relevant laws. The same applies to laboratories dealing with flammable liquids. This paper verified the applicability of the procedure for classifying explosion hazard areas according to the Korean Industrial Standards when flammable liquid release from the laboratory to form an evaporative pool, and also verified the effect of a change in ventilation speed on the release characteristics. Through this, it was found that it was difficult to apply the criteria for the classification of places at risk of explosion according to the Korean Industrial Standards, and special safety measures should be prepared.

The effect of washing fingerprints deposited on glass that were contaminated with a flammable liquid (gasoline, kerosene, diesel, and thinner) was studied by washing with hexane or heptane. The fingerprints were visualized using fuming cyanoacrylate, followed by basic yellow 40 staining. After comparing the washing effect, by dividing one fingerprint into four sections, it was confirmed that the ridge detail was damaged by dissolving the fingerprints in flammable liquid. As a result of washing fingerprints contaminated with flammable liquids using hexane or heptane, fingerprints contaminated with gasoline, kerosene, and thinner did not show a washing effect because the ridge detail was damaged at the time of contamination, and only fingerprints contaminated with diesel exhibited improved ridge detail quality. Because hexane and heptane washing damage the ridge detail, it was found that fingerprints contaminated with gasoline, kerosene, and thinner were better enhanced directly without the washing process. In addition, it was found that the amount of the washing solvent and contact time should be minimized when washing fingerprints contaminated with diesel.
