1 1 IMPROVISED EXPLOSIVE DEVICES (IED)

2 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 3 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 IED

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

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

6 6 Briefcase Bomb with Mechanism

7 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 8 Chain of Detonation Main Charge BoosterBooster Detonation Wave Carrier (Cordtex) Detonator Flame Carrier Flame Producer

9 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 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 11 Explosive Accessories Fuse Burning Delay FuseDetonator Safety FuseCordtex

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

13 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 14 Types of Initiation Mechanism… Ambient Temperature Smoke/Gas Sound IR Rays Proximity Humidity X Rays Light Command Car remote Cordless Bell FM Radio Command Wire Aero Modeling

15 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 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

21 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 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 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 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 25 Search Rules & Technique Points to Remember Dont touch or remove the packet Dont open with hands or puncture Dont submerge in water Dont accept identification mark on the face value Dont bring suspect bomb to police station

26 26 Search Rules & Technique Points to Remember Dont open unless duty bound Evacuate the people to a safe area Dont use radio Open all doors and windows Dont be a Dead Hero

27 27 Scooter Bomb found at Bombay in March,1993

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