Practical Fire and Arson Investigation (2nd ed.)
The CVFI program is governed by the official guidelines published in the application packet. This webpage is designed to be a digest of those policies and procedures. The CVFI exam is given only in conjunction with an approved vehicle fire investigation course. It is NOT available by proctor. The primary reference source for exam questions is NFPA The exam consists of 75 random questions from a pool maintained by the National Certification Board. The examination session is closed book and limited to two hours.

The essence of the investigation of fire and explosion incidents is embodied in the use of the scientific method, which has traditionally been used in the physical sciences and it forms the basis for legitimate scientific and engineering investigations. The combustion and fire sciences involve complex phenomena, and the advancement of these sciences has helped to build a technical foundation for the discipline. The challenge for the fire investigator is the practical application of fundamental knowledge to the investigation of fires. Such fundamental knowledge can be exploited through the development of models to overcome some of the complexities of the combustion phenomena that limit practical application. Mathematical fire modeling provides the fire investigator with tools for the testing of hypotheses associated with the origin and cause of a particular fire event.
Fire 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.
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.
