Explosions & Arson Investigation

This topic covers the forensic investigation of explosions and arson, important for understanding fire-related crimes and terrorist activities, relevant to Zambian tertiary education in forensic science and security studies. You will learn the differences between low and high explosives, the combustion process in fires, and the critical task of locating the point of origin or bomb seat. The module details evidence collection protocols for explosive residues and fire debris, using appropriate containers to prevent loss. Analytical schemes are presented, including preliminary color tests (e.g., diphenylamine) and confirmatory instrumental methods like chromatography and spectroscopy for explosives. For fire debris, techniques such as passive headspace absorption and GC/MS are explained. This knowledge equips Zambian university and college students for roles in bomb disposal units, fire investigation teams, and forensic laboratories, contributing to national security and public safety. Mastering this content is essential for passing examinations and handling complex, high-stakes investigations in your professional future.
