Hydrocarbon accelerants
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. 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.
