Standard Test Method for Ignitable Liquid Residues in Extracts from Fire Debris Samples by Gas Chromatography-Mass Spectrometry

Importancia y uso:

4.1 The identification of an ignitable liquid residue in samples from a fire scene can support the field investigator’s opinion regarding the origin, fuel load, and incendiary nature of the fire.

4.1.1 The identification of an ignitable liquid residue in a fire scene does not necessarily lead to the conclusion that a fire was incendiary in nature. Further investigation can reveal a legitimate reason for the presence of ignitable liquid residues.

4.1.2 Because of the volatility of ignitable liquids and variations in sampling techniques, the absence of detectable quantities of ignitable liquid residues does not necessarily lead to the conclusion that ignitable liquids were not present at the fire scene.

4.2 Materials normally found in a building, upon exposure to the heat of a fire, will form pyrolysis and combustion products. Extracted ion profiling and identification of specific compounds or classes of compounds described herein can facilitate the identification of an ignitable liquid in the extract by reducing interference by components generated as products of pyrolysis.
