If you presently work at an airport doing security work you should immediately contact the United Federation LEOS-PBA to find out how we can help you and your co-officers improve your wages, benefits and working conditions under a United Federation LEOS-PBA union contract.
Airport security refers to the techniques and methods used in protecting passengers, staff and aircraft which use the airports from accidental malicious harm, crime and other threats.
Large numbers of people pass through airports everyday, this presents potential targets for terrorism and other forms of crime because of the number of people located in a particular location. Similarly, the high concentration of people on large airliners, the potential high death rate with attacks on aircraft, and the ability to use a hijacked airplane as a lethal weapon may provide an alluring target for terrorism, whether or not they succeed due their high profile nature following the various attacks and attempts around the globe in recent years.
Airport security attempts to prevent any threats or potentially dangerous situations from arising or entering the country. If airport security does succeed in this, then the chances of any dangerous situations, illegal items or threats entering into both aircraft, country or airport are greatly reduced. As such, airport security serves several purposes: To protect the airport and country from any threatening events, to reassure the traveling public that they are safe and to protect the country and their people.
Monte R. Belger of the U.S. Federal Aviation Administration notes "The goal of aviation security is to prevent harm to aircraft, passengers, and crew, as well as support national security and counter-terrorism policy."
Airport enforcement authority
While some countries may have an agency that protects all of their airports in other countries like the United States, the protection is controlled at the state or local level. The primary personnel will vary and can include:
A police force hired and dedicated to the airport i.e. the Irish Airport Police Service
A branch (substation) of the local police department stationed at the airport
Members of the local police department assigned to the airport as their normal patrol area
Members of a country's airport protection service
Police dog services for explosive detection, drug detection and other purposes
Other resources may include: Security guards Paramilitary forces Military forces
Process and equipment
Some incidents have been the result of travelers being permitted to carry either weapons or items that could be used as weapons on board aircraft so that they could hijack the plane. Travelers are screened by metal detectors. Explosive detection machines used include X-ray machines and explosives trace-detection portal machines (a.k.a. "puffer machines"). In the United States the TSA is working on new scanning machines that are still effective searching for objects that aren't allowed in the airplanes but that don't depict the passengers in a state of undress that some find embarrassing. Explosive detection machines can also be used for both carry on and checked baggage. These detect volatile compounds given off from explosives using gas chromatography.
A recent development is the controversial use of backscatter X-rays to detect hidden weapons and explosives on passengers. These devices, which use Compton scattering, require that the passenger stand close to a flat panel and produce a high resolution image. A technology released in Israel in early 2008 allows passengers to pass through metal detectors without removing their shoes, a process required as walk-though gate detectors are not reliable in detecting metal in shoes or on the lower body extremities. Alternately, the passengers step fully shoed onto a device which scans in under 1.2 seconds for objects as small as a razor blade. In some countries, specially trained individuals may engage passengers in a conversation to detect threats rather than solely relying on equipment to find threats.
Generally people are screened through airport security into areas where the exit gates to the aircraft are located. These areas are often called "secure", "sterile" and airside. Passengers are discharged from airliners into the sterile area so that they usually will not have to be re-screened if disembarking from a domestic flight; however they are still subject to search at any time. Airport food outlets have started using plastic glasses and utensils as opposed to glasses made out of glass and utensils made out of metal to reduce the usefulness of such items as weapons.
In the United States non-passengers were once allowed on the concourses to meet arriving friends or relatives at their gates, but this is now greatly restricted. Non-passengers must obtain a gate pass to enter the secure area of the airport. The most common reasons that a non-passenger may obtain a gate pass is to assist children and the elderly as well as for attending business meetings that take place in the secure area of the airport. In the United States, at least 24 hours notice is generally required for those planning to attend a business meeting inside the secure area of the airport.
