 NIJ and Jensen Hughes: Advancing the Forensic Analysis of Ignitable Liquid Fuel Fires

              The reported study by the Jensen Hughes engineering firm evaluated the differences in fire dynamics and fire damage between ignitable liquid fuel fires in open-burning and enclosed scenarios, with and without furnishings.
Abstract
              This study provides fire investigators new methods and guidelines for conducting calcination depth measurements and analyzing heat impact on gypsum wallboard relative to fire patterns. The study findings increase the likelihood of positive ignitable liquid residue (ILR) identification on typical building materials (composite furniture materials, plywood, vinyl, and carpet/pad). The procedure used enables investigators to assess objectively burn patterns on various flooring materials in order to determine whether the source of the pattern is the burning of flammable liquid or other combustible materials, such as furniture or plastic toys. The procedure used provides a means to measure the calcinations depth of gypsum wallboard for pattern analysis to aid in fire origin determination and fire impact severity. The results of this study have been incorporated into the Society of Fire Protection Engineers (SFPE) Handbook of Fire Protection Engineering (5th edition, 2016) and the National Fire Protection Association (NFPA 921 Guide for Fire and Explosion Investigations (2017).
