10.5 Nature, Types and Examination of Explosives

The nature: the rapid-energy release (the blast's mechanics: the pressure wave, the fragmentation, the thermal). The types: the low (the propellants — the deflagration) vs the high (the detonation — the TNT, RDX, the ANFO-and-IED world); the military vs the improvised (the IED — the modern asymmetry's weapon — the LAW5508-IHL world's face); the initiators (the detonators, the fuses). The examination: the scene's discipline (the post-blast's faces — 10.6); the residues' chemistry (the swabs-and-debris — the explosive's identification by the lab's instruments); the device's reconstruction (the container, the initiation, the triggering — the bomber's signature).
