A:

Protective barriers function primarily by preventing and reducing the injury caused by projectile weapons. The object of these protective barriers is to mitigate the effect of the projectile. Natural barriers are usually designed to resist the impact of falling objects. They are composed of stone, dirt, rock, gravel, brick, steel, brick, and stone. Structural barriers are composed of concrete or cement, metal, masonry, stone, and reinforced concrete (Gibler et al., 2018). The type of materials used to construct and maintain structural barriers varies by state. Protective barriers to ensure public health and safety are designed to prevent or minimize health hazards to the people who occupy and use the site and prevent or minimize the spread of disease, illness, or injury to the people who use and occupy the site. Examples include walls, fences, and barriers on the grounds and building boundaries. Structural barriers include all structures built upon the ground to protect or isolate persons or property from harm or prevent damage by natural or human-made events (Gibler et al., 2018).Natural protective barriers are large bodies of water, or areas on land, that serve as barriers to flooding or other natural events, or provide a natural barrier to erosion. They include ponds, lakes, rivers, canals, or other water bodies (Liu et al., 2017). Natural barriers used to protect a highway include embankments and banks, retaining walls, roads, bridges, culverts, ditches, gates, and other structures that provide natural barriers to floodwaters or other roadway threats. Active barriers and passive structural barriers often overlap. If the barriers do not overlap, the passive structural barrier should be considered the barrier that prevents injury. A passive structural barrier is a physical barrier that remains for as long as the storm surge exceeds it and does not reduce height significantly (Liu et al., 2017).On the other hand, a structural barrier is a building or tower that will increase in height and height at an increased rate. Active structural barriers are barriers that have been developed to remove them. Passive structural barriers are barriers that have been developed for the intention of preventing access to them (Liu et al., 2017). One of the disadvantages of a medium-security facility is that it is considered a deterrent and cannot be made more secure. The main advantage of a medium-security facility is that it is relatively safe, and therefore offers a greater chance of the detainee gaining immunity from prosecution (Liu et al., 2017).

The protective barrier is the physical barrier established and maintained as the natural barrier within the property, within the structure, or within the building for any purpose of protection, property protection, or protection of life. The protective barrier is a fence, wall, or fence line that encloses the property, the structure, or the building and is maintained to prevent entry by persons who are not authorized to enter. Protective barriers can be found in buildings and other structures such as bridges and fences, and vehicles. These barriers should be used at intersections and other vital junctions to reduce the risk of accidents or traffic congestion, causing a crash (Fennelly, 2020).The passive structural barriers are barriers that are not part of a building’s foundation. These barriers are typically made of wood, concrete, or steel and are designed to prevent the building’s foundation from moving during earthquakes. The active structural barriers are part of a building’s foundation and are designed to move during earthquakes (Spaeth & Belle, 2019). These barriers can be made of concrete, brick, or steel. The active intervention of the person in charge of building the barrier; passive barriers, on the other hand, are meant to be built without the person in charge having any knowledge of what is going on or being involved in building the barrier. Passive barriers are barriers that have no structural function. They are not used to keep people out of a building, but to prevent them from entering. Active structural barriers are those who have a structural function. They are used to keep people out of a building (Spaeth & Belle, 2019).The advantages of medium-security facility already have a protective barrier, but the protective barrier is not effective in preventing a specific threat. In such a situation, the most excellent approach is using a barrier that can effectively protect the entire facility. The security barriers used for medium-security facilities may have a lower degree of physical resistance to tampering. However, these barriers may not be self-closing or maybe more easily damaged by bolt breakage (Spaeth & Belle, 2019). The vulnerabilities may result from a relatively small number of passing through it or an open hole. The disadvantages of medium-security building, they want to have many windows and doors that can be closed to minimize exposure to external threats. The physical barrier can be achieved in a medium-security facility by introducing a metal gate placed at the security area entrance and has a high density. In this security area, access to security personnel is restricted. This security measure can be applied to all the security areas in the medium-security facility (Spaeth & Belle, 2019).
