Improvised explosive devices (IEDs) are easy to assemble, homemade explosives, made by unauthorised persons and/or placed in an improvised way
2
. They are composed of at least five key components:
a switch, a power source, an initiator, a container and an explosive charge
What are the 4 components of an IED?
IEDs generally have four main components as shown in Figure 1. These components can be remembered using the acronym, PIES:
a power supply, an initiator, an explosive, and a switch
.
What are the 3 main types of IED?
Common forms of VOIED include the
under-vehicle IED (UVIED), improvised landmines, and mail bombs
.
What is the 5 25 rule IED?
The 5-and-25 refers to
distances to “clear” any time a patrol or vehicle stops
. Soldiers should look out for anything suspicious within a five-meter radius if they’re in a vehicle; if their vehicles stop, they should clear a 25-meter perimeter around the vehicles.
What are the main components of a IED?
IEDs consist of a variety of components that include an
initiator, switch, main charge, power source, and a container
. IEDs may be surrounded by or packed with additional materials or “enhancements” such as nails, glass, or metal frag- ments designed to increase the amount of shrapnel propelled by the explosion.
How are IED detected?
Since most of the IEDs have the ferromagnetic properties, the magnetic field produced around the body by the IED can be detected by
3-axis fluxgate sensor array system
. … In order to reduce the effects of the Earth’s magnetic field, the total gradient contraction was used to detect the IEDs.
What is ied in school?
Introduction to Engineering Design
(IED) is a high school level course that is appropriate for students who are interested in design and engineering. … IED gives students the opportunity to develop skills and understanding of course concepts through activity-, project-, and problem-based (APPB) learning.
What is the most powerful explosive material?
One of the most powerful explosive chemicals known to us is
PETN
, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
What is the most unstable explosive?
Nitroglycerin
is the most dangerous and unstable explosive know to man.
What is used to wash off explosive residue?
Explosive residue can be removed by repeated washings with
soap and water
.
What is a command IED?
improvised explosive devices
Command-initiated IEDs are detonated through human interaction with the triggering mechanism. Typically, a receiver on the explosive triggers detonation when an electronic impulse is sent over a wire circuit or via wireless signal.
What is IED in electrical?
An acronym for
Intelligent Electronic Device
. An IED, as it relates to the protection and power system automation industry, is a device that performs electrical protection functions, advanced local control intelligence, has the ability to monitor processes and can communicate directly to a SCADA system.
What is Army 5 C’s?
In their first week of training, Soldiers are taught the “5 Cs” of encountering a roadside bomb. If a suspicious item is found, Soldiers are taught to:
confirm, clear, call, cordon and control
.
Which component of an IED creates an electrical charge?
The power source such as a Battery
of an IED creates an electrical charge.
What is on an explosive hazard 9 line report?
a. Gather and record information in a standard 9-line Explosive Hazard Spot Report format. (1) Line 1
: Date and time of the fall, impact, or finding of the UXO/IED item(s)
. (2) Line 2: The exact location of item(s) grid coordinate (8-digit minimum) including landmarks, reference points, or street addresses.
Which sensor is used for bomb detection?
Nanomaterial-based chemiresistive-gas sensor
is an important explosives detection method due to the small device size, low energy consumption, high and rapid response (Senesac and Thundat, 2008; Che et al., 2010; Chen et al., 2010; Engel et al., 2010; Zu et al., 2013; Guo et al., 2014).
