  • Forensic Analysis of Fire Debris Residues
    INDIANAPOLIS-MARION COUNTY FORENSIC SERVICES AGENCY Doctor Dennis J. Nicholas Institute of Forensic Science 40 SOUTH ALABAMA STREET INDIANAPOLIS, INDIANA 46204 PHONE (317) 327-3670 FAX (317) 327-3607 EVIDENCE SUBMISSION GUIDELINE #4 FORENSIC ANALYSIS OF FIRE DEBRIS RESIDUES INTRODUCTION A fire investigation is an unenviable task. The devastation, charred debris, collapsed structures, water soaked ashes, together with the smoke and stench, makes the task uninviting and seemingly impossible. The basic role of an investigator at a fire scene is twofold: firstly to determine the origin of the fire (the site where the fire began), and secondly to examine closely the site of origin to try and determine what it was that caused a fire to start at or around that location. An examination would typically begin by trying to gain an overall impression of the site and the fire damage; this could be done at ground level or from an elevated position. From this, one might proceed to an examination of the materials present, the fuel load, and the state of the debris at various places. Fire debris is a general term used to define the materials collected from a fire scene for laboratory examination. When a fire investigator suspects that a fire might have been deliberately set using accelerants such as ignitable liquids, it is possible to collect and analyze fire debris to see if such products are present. Combustion requires three elements — heat, oxygen, and fuel. Fire will be extinguished when any one of these three elements is absent. Fire does not burn solids or liquids (in general), but rather the gases formed above them.

  • Residues of Fire Accelerant Chemicals Volume I: Risk
    RESIDUES OF FIRE ACCELERANT CHEMICALS VOLUME I: RISK ASSESSMENT Prepared for: Intermountain Region USDA Forest Service Ogden, UT By: Headquarters: 8000 Westpark Drive, Suite 400 McLean, VA 22102 October 16, 2002 Abstract This report summarizes the results of quantitative human health and ecological risk assessments of chemical residues in the environment from the use of a variety of accelerants to ignite prescribed burns. On a per-unit basis for each ignition method, no risks were identified for human health, nor for general wildlife species. However, consideration should be given at the planning stage to protecting sensitive aquatic species in small watersheds that have limited potential for diluting residue chemicals that may run off or erode to surface water.

Askim and Kenneth S. Suslick* 15 16 DOI: 10.1039/x0xx00000x A linear (1x36) colorimetric sensor array has been integrated with a pre-oxidation technique for detection and identification of a variety of fuels and post-combustion residues. The pre-oxidation method permits the conversion of fuel 17 www.rsc.org/ 18 vapor into more detectable species and therefore greatly enhances the sensitivity of the sensor array. The pre-oxidation 19 technique used a packed tube of chromic acid on an oxide support and was optimized in terms of the support and 20 concentration. Excellent batch to batch reproducibility was observed for preparation and use of the disposable pre- 21 oxidation tubes. Twenty automotive fuels including gasolines and diesel from five gasoline retailers were individually 22 identifiable with no confusions or misclassifications in quintuplicate trials.

  • F-500 Project
    Introduction This project was undertaken to address concerns encountered in the field by fire investigators and Accelerant Detection Canine Teams in relation to the potential of ignitable liquid “masking” properties of certain fire suppression additives. As modern fire suppression tactics evolve, certain chemical additives are commonly being introduced into the extinguishment phase of fire department operations. The introduction of these chemical additives present a concern to the fire investigation community relative to their potential affect on the forensic investigation of a fires cause, where factors relative to the fires ignition and spread may rely on the identification or confirmation of ignitable liquid residues as often relied upon to identify the use of an accelerant in an intentionally set fire. Today’s fire and arson investigators have many resources available to them to better pinpoint the origin and cause of a fire. One of those resources includes the use of a certified accelerant detection K9 team. This team is a valuable tool in identifying the presence of ignitable liquids through the use of their keen olfactory senses. For detection to be possible the K9 Team, much like the forencic laboratory Analyst, rely on the presence of ignitable liquid vapor residue in or on substrate materials left after a fire occurs. The concern over the use of a suppression additive focuses on its potential to mask or chemically alter the ignitable liquid to a state K9 Shadow making a positive indication which would inhibit the canine or crime laboratory from for ignitable liquid in Arson Bureau test identifying the presence of the original ignitable liquid in facility.

  • High-Performance Ceramic/Epoxy Composite Adhesives Enabled by Rational Ceramic Bandgaps J
    www.nature.com/scientificreports OPEN High-performance ceramic/epoxy composite adhesives enabled by rational ceramic bandgaps J. B. Hu High over-all properties, including low dielectric loss, high breakdown strength, high mechanical shock strength, high thermal conductivity and high weight stability, are very difcult to simultaneously achieve in electrical-insulation applicable cured potting-adhesive materials. To deal with this challenge, in this work, we have designed and fabricated a series of epoxy based composite potting-adhesives flled with low-cost and high-performance inorganic micro-particles including alpha-silica, alpha- alumina and alpha-SiC. Combination employment of high-molecular-weight and low-molecular-weight epoxy resins as matrices has been made. Heat-induced curing or crosslink of resin matrices has been carried out. Large band gap of silica fller has endowed the cured composite with high breakdown strength and ageing breakdown strength, and meanwhile relatively high deformation trait of silica has led to high shock strength of cured composite. Silica fller has been found to be superior to other two fllers, namely, optimal over-all properties such as dielectric, breakdown, mechanical and thermal features have been obtained in silica flled cured composite. High breakdown strength of ~48 MV m−1 and shock strength of ~9950 J m−2 have been achieved in silica loaded composite. This work might open up the way for large-scale fabrication of promising epoxy-based hybrid potting-adhesives. Recently, potting adhesive materials with promising electrical, mechanical and thermal properties have triggered general attention and research interest in the feld of fabricating aerospace applicable special power supplies1.

Common accelerants include petrol, kerosene, diesel fuel etc. and when found at a fire scene without logical explanation, can be proof of intent and preparation - thus good evidence to suggest arson. The use of canines to aid the detection of accelerant in a fire investigation was first proposed in the early 1980’s in the US State of Connecticut. Canines had been used successfully in the US for some time in drug detection and bomb detection and a feasibility study conducted on canines’ ability to detect accelerant suggested success in this area also. On 1st May 1986, a training program was initiated as part of a joint effort between three agencies; the Bureau of Alcohol, Tobacco and Firearms (BATF), the Connecticut State Police (CSP) and New Haven State’s Attorney Generals Office. A black female Labrador retriever, “Mattie” was obtained from the Guide Dog Foundation and was trained by the CSP. In the first 38-day period Mattie was trained to detect various odours associated with flammable liquids. As the training progressed, Mattie was able to detect these odours at very low levels, and tests proved that she could identify 17 different odours.
