Detection of fire accelerants is the process that a fire investigator uses to determine if fire accelerants were used at a fire scene. This process involves a combination of both field work and laboratory analysis by fire investigators and chemists. In order for a positive identification of a fire accelerant to occur both field work and laboratory analysis must take place. This is because when a fire accelerant is used only ignitable liquid residues (ILRs) remain at the scene. It is the chemists job to identify these ILRs and the investigators job to determine if they were used as fire accelerants or just present at the scene under normal circumstances. ==Fire accelerant vs. ignitable liquid== It is common for the words fire accelerant and ignitable liquid to be used synonymously. It is important to understand that an ignitable liquid is a liquid that will readily ignite when exposed to an ignition source, while a fire accelerant is a material that is used to increase the rate of combustion for materials that do not readily burn. Ignitable liquids are not always fire accelerants, they may just be present at the scene under normal circumstances.〔 Gasoline is the most common fire accelerant used 〔 but it could also be present at a scene as an ignitable liquid due to gasoline being a common fuel. Although ignitable liquids are the most common fire accelerants it is possible to have other chemicals being used as a fire accelerant. Gases such as propane or natural gas could also be used to accelerate a fire. Detecting the use of a fire accelerant at a crime scene can be the difference between classifying a fire as accidental or as an arson. Once a case is determined to be an arson, the detection of fire accelerants will hold strong evidentiary value which the prosecutor can use during the trial should someone be charged. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Detection of fire accelerants」の詳細全文を読む スポンサード リンク
