Barriers Name: Institution: Barriers Purpose of the Chapter The purpose of the chapter is to explore different types of barriers and obstacles, their functions and importance, and the ease at which they operate and accommodate the changing needs in the environment. 2. Key Question at the Heart of this Chapter The key question at the heart of this chapter is whether barriers are effective in ensuring physical security or not.

3. Important information in the Chapter The writer makes the assertion that the key role of barriers is to protect against penetration by stealth and by force. Ideally, most barriers are designed to give people a difficult time when going in and give them an easier time while leaving. He, however, argues that physical barriers such as locks and bolts, in isolation may be ineffective in ensuring total physical security. It is for this reason that such barriers have to be reinforced by monitoring, for example, from security guards. In addition, the writer gives the functions of barriers as instruments for directing, delaying and defining but clearly emphasizes the ineffectiveness of barriers in preventing forced penetration into certain areas or premises. Key to the content of the information in this chapter is the importance of reinforcement of barriers to increase security and safety.

The writer also gives examples and the functionality of different barriers, which include magnetic and electro-magnetic doors, vehicle doors, revolving doors and mantraps. 4. Main Inferences in the Chapter The first significant conclusion that can be drawn from this chapter is that physical barriers, that are reinforced either by security guards, sensors, alarms or cameras among other monitory devices, increase the effectiveness of the function for which they are made for, which is to ensure security and safety. The writer also infers that in as much as some firms and organizations take state of the art security pre-cautionary measures, they should not do so to a level of instilling fear and panic in people. The writer also using the different examples of barriers gives the difference between the high cautions exercised in entering of buildings, but the relaxed measures put in place in the exiting of buildings.

5. Key Concept in the Chapter The key concept in this chapter is the establishment of the key functions of barriers, which are directing, defining and delaying-yet without back up from a dependable monitoring system, loose their effectiveness. At the same time, even with a robust barrier and monitoring system, forces such as natural occurrences may come in the way of effective running of barriers, and, therefore, increasing the chances of insecurity. 6. Main Assumptions The writer assumes that the audience will be able to capture the deep vocabularies used to explain technical ideas regarding barriers. The writer also assumes that the audience is one that entrusts their security to the presence of barrier and monitoring systems. 7.

Implications If people take seriously what the writer is saying, some significant implications include the knowledge that barriers can be effective in upholding safety and security, but that they should be reinforced using monitoring systems. At the same time, individuals should not entrust their lives to the protection of either, or the combination of both, but should also exercise due diligence in ensuring they are safe and secure on a personal level. Failure to accept the author’s message implies that one entrusts barriers fully to safeguard their lives and livelihoods, and this means a false sense of total security.
