Airport security
Process and equipment
A police force hired and dedicated to the airport e.g. 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 Play media Some incidents have been the result of travelers carrying either weapons or items that could be used as weapons on board aircraft so that they can hijack the plane. Travelers are screened by metal detectors and/or millimeter wave scanners. 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 are not allowed in the airplanes but that do not 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.
