Introduction to Explosive Recognition

2



The use of metal detectors and visual searches of persons and carried bags at schools and public buildings has been aimed at reducing the introduction of weapons into these buildings. The success of these efforts have forced the conversion to explosives which are not readily detected by metal detectors or visual searches. These explosives can be set off by a number of different devices from a simple fuse to timed electronic detonators, cell phones or suicide switches.

5



Detonators

• The term detonator and blasting cap are interchangeable. Detonator is a term used by the commercial manufacturers and blasting cap is a term used by the military.

• The net explosive charge in detonators is usually no more than a few grams

6



• Electric Detonators consist of a small cylindrical shell containing a high explosive that is initiated when an electric current is sent to thru a bridge wire initiating the initiating charge and sympathetically detonating the base charge.

Detonators

• Non Electric Detonator is designed to detonated from the spit of flame provided by a safety fuse of other flame producing device.

7



Detonators

• The Modular IED Training aid contains simulated electric detonators used in IEDs and are activated by light, motion, timer or remotely.

• The Explosive Recognition Training aid contains both the simulated electric and non-electric detonators; plastic shock tube and detonating cords

Modular IED Training KitTilt Motion Activated Detonator Assembly

This detonator assembly could be used in a package or briefcase bomb. The package would be placed in an area and activated by the arming switch. Any movement or tilting of the package would cause the mercury to close the circuit and the bomb would explode.

Commercial Explosives

• There are various mixtures and trade names are available in the commercial blasting industry

• Waste Gels (Slurries), Emulsions and the term Dynamite have all been used to categorize commercial explosives.

13



Dynamite

• Dynamite is one of the most widely used high explosives in blasting operations. Dynamites vary in their explosive content, strength and sensitivity

• Dynamite usually will be found in sticks or cylinder form and wrapped in buff, white or colored waxed paper. Their diameters and lengths also vary with manufactures

• The ATF list three different Dynamites: Straight, Ammonia and Semi Gelatin

14



Dynamite• Straight Dynamite has a sweet pungent odor

because of the Nitroglycerin (NG) content. Inhalation of the fumes will cause severe headaches. It is sensitive to shock and friction

• Ammonia Dynamite has a pungent sweet odor because of the slight NG content. It is less sensitive to shock and contains mostly ammonium nitrate.

• Gelatin Dynamite is soluble in water and varies from a thick liquid to a tough rubbery gelatinous substance. These are designed for wet blasting operations’

15



Dynamite• The Explosive Recognition Training aid

contains a simulated samples of three types of Dynamite.

• The Modular IED Training aid contains a simulated dynamite stick. One stick has a well for the detonator. Any of the detonator assemblies could be used with this simulant package.

Water Gels / Emulsions / Powers• Water Gel is an explosive that

contains a substantial amount of water, oxidizers and fuel plus a cross linking agent.

• Emulsions are explosive material that contain substantial amounts of oxidizers dissolved in water droplets surrounded by a fuel that is incapable of blending or mixing.

• Powders – black powder (saltpeter – potassium nitrate) formula was used as early as the 10 century by the Chinese. It is considered a blasting agent.

17



• Binary, or two components, explosives are blasting explosives that are formed by mixing two commercially manufactured prepackaged chemical ingredients (oxidizer and flammable liquids) which individually are not classified as explosives but which are mixed for a detonable mixture

• The Explosive Recognition Training aid contains simulated samples of binary explosive, water gels, emulsions and powders for hands-on training.

Binary Explosives

18



• The principle difference between military explosives and commercial explosives are that military explosive materials are designed for longer storage and contain no NG

• The velocities of military explosives are generally greater than their commercial counterparts

Military Explosives

19



• TNT is the most common military explosive. Used alone or as part of a composite explosive, is used widely as a booster, bursting or demolition charge.

• Amatol is a mixture of molten ammonium nitrate and TNT.

• PETN (Pentoerythrite Tetranitrate) is more sensitive to shock or fiction than TNT.

• RDX is one of the most powerful explosive.

• The war on terror and most recently the increased news coverage of bombings has made the use of the term Improvised Explosive Device (IED) a daily part of Law Enforcement’s vocabulary

• An IED simply stated is a homemade explosive (HME), concealed to prevent its being detected and designed to detonate at a predetermine time to kill or destroy property.

• The IED Training kit is designed to increase awareness of security personnel to IEDs made from normal items used on a daily basis

IED Components

• Power Supply

• Detonator

• Explosive Main Charge

• Sensor (switches/times)

Both the Modular IED Training and Explosive Reognition Training kits have samples of IED components

This lunch box looks like ones you see everyday. It contains a sandwich, a small thermos, a can of soda and a small container of Pringles. However, the soda can is filled with smokeless powder and has a fuse that can be light to detonate the powder. The Pringles and thermos contains plastic explosive, a detonator, battery and suicide switch. The sandwich is a block of plastic explosive, detonator, battery and switch in a plastic bag and wrapped in aluminum foil. This quantity of explosive would cause a large amount of damage or injuries.
