This textbook for the fire and law enforcement investigator, prosecutor, and fire protection professional provides a thorough understanding of fire dynamics, describing and illustrating a totally new systematic approach for reconstructing fire scenes. The approach applies the following principles of fire protection engineering along with forensic and behavioral science: identifiable fire pattern damage, human factors, physical forensic evidence of human activity, and application of the scientific method based upon relevant scientific principles and research. Using historical fire cases, the authors provide new lessons and insight into the ignition, growth, development, and outcome of those fires.
