Success Story: Advancing the Forensic Analysis of Ignitable Liquid Fuel Fires

February 2018

Overview

Investigating fires with “liquid fuel” is particularly challenging, as the combustion of building materials often conceals the presence of the fuel. JENSEN HUGHES, led by Dr. Daniel Gottuk, evaluated the differences in fire dynamics and fire damage between ignitable liquid fuel fires in open-burning and enclosed scenarios, with and without furnishings. Full-scale testing was conducted to identify optimum sampling locations within fire patterns to identify ignitable liquid residue (ILR). The study provides fire investigators with new methods and guidelines for conducting calcination depth measurements and analyzing heat impact on gypsum wallboard (sheetrock) relative to fire patterns.

“Dr. Gottuk’s work has reduced the number of inaccurate arson determinations based on low burns and holes in the floor. It has even played a role in reversing some wrongful convictions based on the misconception that ignitable liquids burn holes in floors.”
