In this study, we focus on early detection of fire caused by 'flammable liquid', which is a source of fire, and securing of the 'Golden Hour' to collect and analyze evidences. An experiment was conducted by applying a certain amount of oil, thinner, gasoline, diesel and kerosene to be ignited artificially. Three methods of extinguishing the fire were used. The first was water, the second, fire extinguishers, and the third, natural extinguishing without any artificial extinguishing method. The reaction and detection of liquid residues were measured by a gas sampler and gas chromatography (GC/MS) over time after extinguishing the fire and collecting the evidences. The results confirm the possibility of extracting reactions with the gas sampler and GC/MS from the flammable evidences over time.
