What are the components of an explosive device?
An IED has five components: a switch (activator), an initiator (fuse), container (body), charge (explosive), and a power source (battery).
What is used to detect IED?
Most common detection methods are: portable single-energy x-ray systems; • non-linear junction detectors (NLJD). Portable single-energy x-ray systems are used to determine the construction of the found IED.
What is the importance of improvised explosive device?
An Improvised Explosive Device (IED) is a bomb. IEDs are designed to destroy or damage personnel or property. In some cases, they are used to target, distract, disrupt or delay first responders. This tactic may be used to facilitate another type of attack.
Why is it important to study explosives?
The accurate determination of the composition of explosives is very important because variation in composition affects the stability, sensitivity, ignitability, and efficiency of performance of these materials.
What are the 5 correct elements of cages?
Although IEDs can vary widely in shape and size, there are five components common to all IEDs which consist of the switch, the initiator, the main charge, the power source and the container.
What are the main characteristics of explosion?
In general, an explosive has four basic characteristics: (1) It is a chemical compound or mixture ignited by heat, shock, impact, friction, or a combination of these conditions; (2) Upon ignition, it decom- poses rapidly in a detonation; (3) There is a rapid release of heat and large quantities of high-pressure gases …
What are the five 5 types of explosions?
- 1.1 Astronomical.
- 1.2 Chemical.
- 1.3 Electrical and magnetic.
- 1.4 Mechanical and vapor.
- 1.5 Nuclear.
Why is explosive detection important?
Stopping terrorist from using explosives to destroy lives, property, and our sense of security requires vigilance; expertise of both personnel and bomb sniffing dogs; and reliable equipment and systems. Trace detection systems play a critical role in the security screening of individuals, cargo, and checked baggage.
What is the feature of the explosive trace detection machine?
Explosives trace detectors (ETD) are explosive detection equipment able to detect explosives of small magnitude. The detection is accomplished by sampling non-visible “trace” amounts of particulates. Devices similar to ETDs are also used to detect narcotics.
What are some examples of explosive substances?
Examples of explosive and potentially explosive chemicals include:
- Compounds containing the functional groups azide, acetylide, diazo, nitroso, haloamine, peroxide, and ozonide.
- Di- and Tri-nitro compounds.
- Peroxide forming compounds.
- Picric acid (dry)
- 2,4-Dinitrophenylhydrazine (dry)
- Benzoyl peroxide (dry)
What 3 items make up explosive ordnance?
Explosive Ordnance (EO) All munitions containing explosives, nuclear fission or fusion materials and biological and chemical agents.
What are the different types of explosives and their characteristics?
explosive, any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. There are three fundamental types: mechanical, nuclear, and chemical. A mechanical explosive is one that depends on a physical reaction, such as overloading a container with compressed air.
What are three characteristics of all explosions?
What are three characteristics of all explosions? The three characteristics are a large release of energy, production of quickly expanding gas molecules, and a rapid reaction rate.
What is explosive detection device?
Explosive detection is a non-destructive inspection process to determine whether a container contains explosive material. Explosive detection is commonly used at airports, ports and for border control.
