10.6 Evidence Collection Techniques in Post Blast Investigation

1. The scene's securing (the secondary devices' danger — the safety's priority; the perimeter).2. The documentation (the photography, the mapping — the blast's seat's location).3. The seat's excavation (the crater's-and-debris's systematic removal — the layers' sifting).4. The collection (the device's fragments — the container's pieces, the wiring, the power sources, the triggering's components; the residues' swabs; the comparatives — the controls).5. The victims'-and-witnesses' faces (the injuries' pattern — the blast's position; the witnesses' accounts).6. The reconstruction-and-the lab (the device's nature-and-source; the explosive's identification — the maker's-and-method's inference).
