  1. IMPROVISED EXPLOSIVE DEVICES (IED)

  2. Definition An IED is a device, assembled by an organization or an individual in contravention to the existing rules of Law of Nation adopting unconventional or semi-conventional methods of assembling a standard device, ammunition/explosives or commercial, with a criminal/anti-national intention. The design of an IED will depend on the lethality of a bomb

  3. IED • The effects of an IED explosion are not standard and predictable • The effects will vary in each case, depending on : • Components • Quality of explosive • Casing • Quantity of splinters

  4. Components of an IED • Explosives • Detonator • Power Source (Battery) • Initiation Mechanism (Switch)

  5. Switch + Explosive & Detonator Battery - Components of an IED…

  6. Briefcase Bomb with Mechanism

  7. Initiation Mechanism The switch is a mechanism incorporated to ensure initiation of an IED in a predetermined pattern so as to ensure success in destroying the target in a well deliberated manner.

  8. Chain of Detonation Flame Producer Booster Flame Carrier Main Charge Detonation Wave Carrier (Cordtex) Detonator 1 2 3 4 5 6

  9. Explosive and its Accessories A. Flame Producer : Match fuse, Match box, Igniter safety fuse striker B. Flame Carrier : Safety fuse C. Detonator : Safety Fuse Mercury Fulminate ASA Mixture Base Charge (CE)

  10. Explosive and its Accessories… D. Detonation Wave Carrier(Primacord) • Length : 150 m • Explosive : PETN • Deto. Vel. : 6000 to 8000 m/s E. Booster : To boost up the detonation waves • CE Powder : Brown • GC Powder : White F. Main Filling

  11. Fuse Burning Cordtex Safety Fuse Delay Fuse Detonator Explosive Accessories

  12. Initiation Mechanism The switches can either be classified as Electrical, Mechanical & Miscellaneous. Types of Initiation Mechanism • Anti-handling • Delay • Ambient • Command

  13. Types of Initiation Mechanism… Anti-handling • Pressure • Pressure release • Pull • Pull/release • Tilt • Anti-penetration • Lift • Pendulum • Tension Delay • Mechanical Timer • Clock/Watch • Quartz Watch • Electronic Timer • Pyrotechnics • Thermal • Electro Chemical • Chemical • Expanding seeds

  14. Types of Initiation Mechanism… Command • Car remote • Cordless Bell • FM Radio • Command Wire • Aero Modeling Ambient • Temperature • Smoke/Gas • Sound • IR Rays • Proximity • Humidity • X Rays • Light

  15. Questioning Technique • What time the bomb will explode ? • Where is the bomb located ? • What type of bomb is ? • How will we get rid of the bomb ? • What is your good name ? • Why have you kept the bomb ? • Where are you speaking from ?

  16. Search Rules & Technique of an IED • Search Rules • Search Technique • What to look for ? (Tell Tale Sign) • Points to remember • Action on locating IED

  17. Search Rules & Technique Search Rules • Don’t touch or handle suspicious object • Don’t assume only one device is planted • Use maximum two persons per room or for all area up to 250 Sq. ft. • Use Searches in alternate room

  18. Search Rules & Technique… Search Rules • Give rest after every 10 min. • Never use searches more than necessary • Clearly mark the area searched • Trust nothing and assume nothingsafe

  19. Search Rules & Technique… Search Techniques • Obtain maximum information about the device • Listen before entering a room • Be careful about booby trap, at the door itself and also throughout the search • Make a visual survey of the entire area of the room

  20. Search Rules & Technique… Search Techniques • Divide the area while carrying out Search : • Waist level • Eye level • Ceiling level • Above Ceiling level

  21. Search Rules & Technique Search Techniques • Search back to back by two persons, meet in center and go back again • Rest after each Search • Mark the Searched area • Report about the area and suspected object • Ask for help from expert

  22. Search Rules & Technique What to look for ? (Tell Tale Sign) • Recently disturbed area • Saw dust, Brick dust, Wood chips • Greasy Paper Wrappings • Out of place object • Disturbed Carpenter • Tin foils

  23. Search Rules & Technique What to look for ? (Tell Tale Sign) • Partly open window/door/drawers • Fresh plaster/Cement • Loose Electric Fittings • Fish-line, dirty ropes, electric wire • Cut vegetation

  24. Search Rules & Technique What to look for ? (Tell Tale Sign) • Military container of explosive • Dirty foot prints • Scratched or new paint • New brick work/plaster

  25. Search Rules & Technique Points to Remember • Don’t touch or remove the packet • Don’t open with hands or puncture • Don’t submerge in water • Don’t accept identification mark on the face value • Don’t bring suspect bomb to police station

  26. Search Rules & Technique Points to Remember • Don’t open unless duty bound • Evacuate the people to a safe area • Don’t use radio • Open all doors and windows • Don’t be a Dead Hero

  27. Scooter Bomb found at Bombay in March,1993

  28. Search Rules & Technique Action on locating an IED • Buttress : It’s an action of putting sand bags near the object to protect • Baffling: It’s an action of putting mattress etc. to minimise damage due to blast and fragments • Venting : It’s an action of opening all doors and windows of the room.
