Practical Fire and Arson Investigation - CRC Press BookFire Science Reviews. December , Cite as. Fire investigators have historically relied upon damage as a means to conclude where a fire originated. The concept of fire patterns for this review has been broken into four components that better assist in evaluating their effectiveness in determining an area of origin. The first component evaluated is the ability to assess the varying degree of fire damage along the surfaces of the compartment and contents. Next, the ability to identify clusters of damage was evaluated. Interpretation of the causal factors for the generation of the fire patterns was next appraised.
Practical Applications of Hydrocarbon and Photoionization Detection Units in Arson Investigations
The use of investigative field equipment at crime scenes is an invaluable tool to investigators providing that the equipment is reliable and accurate. At an arson scene, investigators are already at a disadvantage given the nature of the crime. In most circumstances, not only may the evidence be destroyed, but the entire scene may be compromised by smoke, fire, pressurized water and untold personnel from responding emergency agencies. If any one specialized crime scene field investigator needed additional equipment to help locate and interpret evidence at a crime scene, one could argue that an Arson Investigator would be that one. Specialized equipment and portable resources at a fire scene is not a new philosophy. Canines have long been specially trained and used in searching for signs of accelerants and ignitable liquid residues at fire scenes.
