Hydrocarbon accelerants
Websearch for traces of accelerants that could have been used to start a fire. These include: gasoline, kerosene, diesel, heating oils, alcohols, and mineral and white spirits. Samples of debris from fires are routinely analyzed for traces of hydrocarbon accelerants. Mass spectrometery is used to identify and elimi- WebIn a fire atmosphere produced by the burning of common woods, it is relatively easy to detect the presence of hydrocarbon accelerants; however, a fire atmosphere produced by burning synthetic materials that contain many hydrocarbon compounds creates a complex background chromatogram from which it is difficult to identify accelerant components.

WebThis review first mentions ASTM's system in classifying fire accelerants into light petroleum distillates, gasoline, medium petroleum distillates, kerosene, heavy petroleum distillates, and unclassified compounds. Chromatograms with well-resolved n-alkane homolog patterns are most recognizable. WebWhen hydrocarbons burn, they tend to cause physical damage and distinct dark-coloured patterns (see photograph above). Accelerants with high vapour pressures, such as alcohol, acetone, and paint thinner, tend to ‘flash and scorch’ surfaces. Therefore, they cause less physical damage and more superficial scorching.
WebMany so-called accelerants are hydrocarbon-based fuels, sometimes more realistically referred to as petroleum distillates: gasoline, diesel fuel, kerosene, turpentine, butane, … WebA highly flammable, blended liquid composed of more than 300 volatile hydrocarbon compounds manufactured from the fractionation or distillation of petroleum. Gasoline is the most commonly identified ignitable liquid accelerant reported by American forensic laboratories. Its principal use is as a fuel in spark ignited, internal combustion engines.
