    Essentials – Forensic Science Explosives

    DefinitionForensic Explosives Science is the study, detection, identification, analysis and legal interpretation of explosive materials.
    Types of Explosives1. Primary: e.g., Lead azide
    2. Secondary: e.g., TNT, C-4, Semtex
    3. Tertiary (blasting agents): e.g., Ammonium nitrate
    DetectionTechniques include trace detection, bulk detection, and canine detection. Advanced tech involves x-ray diffraction and neutron activation analysis.
    Collection/SamplingPrimarily involves swabbing technique and vacuuming for trace explosive residue collection.
    AnalysisTechniques include spectroscopic methods (FTIR, Raman), chromatographic (GC-MS), and elemental analysis (ICP-MS, XRF).
    Important SkillsAttention to detail, knowledge of chemistry & explosive materials, understanding of legal procedures, lab analysis skills etc.
    Relevant Laws/RegulationsVarious laws/regulations govern the use, transportation, and disposal of explosives, and the subsequent handling of the evidence. E.g., ATF regulations in the U.S.
