C. Short Answer Questions:
1. Describe the components of an IED. How is an IED different from conventional explosives?
Ans: Components of an IED (Improvised Explosive Device). An IED is a homemade bomb constructed and deployed in unconventional ways.
It usually consists of the following components:
(i) Power Source: Provides the necessary energy to detonate the device. Examples include batteries or other electrical sources.
(ii) Initiator: This triggers the main explosive charge. Examples include blasting caps, fuses, or even pressure plates.
(iii) Explosive Charge: The main explosive material that causes the blast. Examples include TNT, RDX, or homemade explosives.
(iv) Switch: A device that controls the firing sequence. It can be a pressure plate, timer, remote control, or trip wire.
(v) Enhancements: Materials like nails, glass, or scrap metal added to increase the destructive force of the blast, causing fragmentation and causing more severe injuries.
An IED different from conventional explosives in the following ways:
| IED | Conventional Explosives |
| Typically homemade, using unconventional materials. | Manufactured in controlled environments, using standardized materials. |
| IEDs use readily available materials and can be assembled with various explosive and non-explosive parts | While conventional explosives have standardized military or commercial components. |
| IEDs are assembled in an improvised manner, often using household items, military ammunition, or commercially available substances. | Conventional explosives are manufactured in controlled industrial settings using specialized techniques and materials. |
| IEDs are relatively cheap and easy to construct, making them accessible to a wide range of individuals and organizations. | Conventional explosives are more expensive and require specialized knowledge and equipment to manufacture and deploy. |
| IEDs can be triggered in multiple ways (remotely, pressure, or timed) | Strictly regulated and handled by trained personnel. |

Ans: Traffic police personnel wear clothes or jackets that reflect light primarily for visibility and safety. These reflective uniforms are designed to catch the light from vehicle headlights, making the personnel easily noticeable even from a distance, especially in low-light or night conditions.
Purpose of Reflective Uniforms:
(i) Enhanced Visibility: Reflective materials, like reflective tape or fabrics, reflect light back to the source, making the wearer stand out against a dark background. This is especially important when directing traffic or patrolling in areas with limited or poor lighting.
(ii) Reduced Risk of Accidents: By increasing visibility, reflective uniforms help drivers and other individuals spot the wearer from a distance, giving them more time to react and avoid collisions.
(iii) Psychological Effects: The visibility of reflective uniforms also conveys a sense of authority and professionalism, which can be reassuring to the public and deter potential threats.
(iv) Identifiable Authority: The uniform signifies authority and order, helping in better control of traffic and managing crowds.
Security Guards Who Should Wear Reflective Uniforms:
(i) Traffic and Parking Security Guards: To manage traffic flow and direct vehicles, especially at night or in low-visibility conditions.
