Standard Practice for Separation of Ignitable Liquid Residues from Fire Debris Samples by Solvent Extraction



Want this as a site license?


1.1 This practice covers the procedure for removing small quantities of ignitable liquid residue from samples of fire debris using solvent to extract the residue.

1.2 This practice is suitable for extracting ignitable liquid residues over a wide range of concentrations.

1.3 Alternate separation and concentration procedures are listed in the referenced documents (Practices E1388, E1412, E1413, E2154, and E3189).

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Significance and Use

4.1 This practice is useful for preparing extracts from fire debris for subsequent analysis by gas chromatography-mass spectrometry (see Test Method E1618).

4.2 This practice is useful to reduce potential fractionation during separation, such as when attempting to distinguish between various grades of fuel oil.

4.3 This practice is particularly useful for extraction from nonporous surfaces such as glass, or the interior of burned containers. It is also well suited to the extraction of ignitable liquid residues from samples that are not amenable to extraction using Practice E1412.

4.4 This practice lacks specificity to separate and isolate ignitable liquids from interfering compounds present in the fire debris.

4.5 This practice is not suitable for the extraction of extremely volatile compounds and ignitable liquids (for example, acetone, butane, ethanol, propane, some cigarette lighter fluids), which could evaporate during the concentration step.

4.6 This is a destructive technique. Whenever possible, this technique should only be used when a representative portion of the sample can be preserved for reanalysis. Those portions of the sample subjected to this procedure could be unsuitable for resampling. If sample spoliation is an issue, a nondestructive extraction technique (for example, Practices E1412, E2154) should be used prior to this technique.
