Standard Practice for Sampling of Headspace Vapors from Fire Debris Samples

SIGNIFICANCE AND USE
This procedure is particularly useful for screening fire debris samples to determine relative ignitable liquid concentrations and possible ignitable liquid class prior to extraction with other techniques.
This practice is useful when volatile oxygenated products such as alcohols or lacquer thinners are suspected.
This practice is the least sensitive of the sample preparation techniques and may not detect quantities of less than 10 μL of petroleum product.
Because this separation takes place in a closed container, the sample remains in approximately the same condition in which it was submitted. Repeat and interlaboratory analyses are therefore possible.
Due to variables in the debris sample condition prior to headspace sampling, complete reproducibility of chromatograms may be difficult to obtain.
4.5.1 To obtain greater reproducibility, use one of the separation procedures which results in a solution of the flammable or combustible liquid residue (see Practices E 1385, E 1386, E 1412, and E 1413.)
High concentrations of highly volatile compounds may swamp the headspace, inhibiting the recovery of less volatile components.
SCOPE
1.1 This practice covers the procedure for removing small quantities of ignitable liguid residue from samples of fire debris by sampling the headspace of the debris container.
1.2 Separation and concentration procedures are listed in the referenced documents. (See Practices E1385, E1386, E1412, and E1413.)
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
