Security Issues in Daily Life - Essay Example Airports serve as gateways for people to reach different places. Thousands of people go to the airport and work for the airport everyday that is why it is a must that airports are secured and safe. Airports are one of the places which practice heavy security inspection (FWAO, 2006). Every area of the airport has security inspections. Upon entrance, most airports will already have metal detectors and x-ray scanners for the baggage. Recent development in technology enables airport security to have a human scan similar to an x-ray baggage scan wherein all metals and explosives can be detected (TSA, 2008). Some of these scanners are the backscatter x-ray and Compton x-ray. After being thoroughly inspected, the airport passengers check-in their baggage. After checking in the baggage, passengers again undergo a more rigid inspection. Body search and metal detectors are again used (Airsafe). This is the last security inspection before leaving the airport. In the US, fingerprinting is now being practiced. They also use smartcard readers. Smartcard technology is an additional security device used in US airports to ensure all the passengers have a record in the system (FWAO, 2006). Together with the fingerprinting, they can name all the passengers and in case of attacks, they can trace the culprits using the finger prints. Aside from these security checkpoints, most airports are equipped with closed-circuit television (CCTV). These are being monitored all day round. Airport security personnel are very diverse. Some of the most common security personnel are the airport police, some local or area police, military men, police dogs and bomb specialists, and airport security. Aside from these security personnel, airports have immigration officers who check the identity of the entering passengers. All of these personnel work together ensuring the safety of the people inside the airport (Airsafe). According to TSA (2008), different

Construction Technology 2 - Essay Example Because the fire curves are modelled on the basis of design fires, the analysis becomes vulnerable to the difference between design fire parameters and the real fire situations that may occur. Furthermore, varying conditions and the global proliferation of standards for fire tests make it imperative that an approximate approach to different situations/standards, for structures (at sea and on land) be adopted. This work aims to analyse fire curves in terms of their vital components/features, simultaneously considering the critical levels at which these vital variables of the standard curves experience a change, with the associated consequences of such, regarding the effectiveness of fire curves at carrying out their function of fire resistance determination. A further look will be taken at the applicability of these curves at sea, with analysis involving a look at the means and extent to which these applications vary, in the approach associated with them. The level of fire resistance in structures (onshore) is generally assessed or analysed by the use of engineering fire design curves. Different types of fire curves and standards are adopted in various parts of the world. Different assumptions are also associated with these different curves. Technically speaking, fire curves are applied to determine the fire resistance rating of passive fire protection systems. This rating is a measure of the time over which a passive fire protection system can resist or withstand a standard fire protection test. Some of the most commonly used standard fire curves include the ISO-834 (BS 476 or DIN 4102), which are relevant to cellulosic structures. There are also the ASTM E119 and UL 1709(or Eurocode 1), applicable to hydrocarbon situations. Engineering design practice generally uses these curves in the context of design fire temperatures, which attempt to
