The Fire Debris database contains chromatographic data and information from fire debris samples that are truly representative of samples that would be encountered in casework. In addition, the ground truth (presence or absence of ignitable liquid residue) is known for each sample. Records consist of examples containing exclusively burned substrate materials as well as mixtures of burned substrates and ignitable liquid residues. Samples in the Fire Debris database are composed of ignitable liquid and substrate contributions that are represented in the ILRC and Substrate databases. NCFS prepares and analyzes samples in accordance with standard forensic test methods.
