AN OVERVIEW OF PASSENGER SCREENING EQUIPMENT AND TECHNOLOGIES AT AIRPORTS
Airports are bustling hubs of activity that see a constant influx of travellers every day. However, with this massive footfall comes the looming threat of terrorism and other heinous crimes. An attack on an airport could potentially result in a catastrophic loss of life, given the sheer number of people in one place. As the aviation industry continues to grow globally, security concerns have become a top priority for regulatory bodies, governments, industry leaders, security professionals and most importantly, the flying public.
The field of airport security has undergone significant advancements in recent years to adapt to the constantly evolving global security threats. One area of focus has been the development and improvement of passenger screening equipment and technologies. The following are some of the major examples of equipment and technologies used for this purpose:
Metal Detectors: Metal detectors are frequently used to scan individuals for metallic objects, particularly weapons like guns or knives. These devices function by emitting a low-frequency electromagnetic field that passes through the body of the person being scanned. When this electromagnetic field is interrupted by a metallic object, the metal detector detects the disruption and alerts security personnel of the presence of the metal object. This method is highly effective at detecting metal objects, making it an essential tool for security and safety purposes in various settings.
Biometric Identification: Airports are utilizing biometric identification technology more frequently to authenticate the identity of travellers. This technology employs facial, fingerprint, or iris recognition to identify passengers and compare them to their travel documents. Its application is especially beneficial in reducing identity fraud and improving the efficiency of airport security checks. By utilizing facial recognition technology, biometric boarding gates authenticate the identity of travellers and enable them to board their flights. These gates scan the traveller’s face and compare it to their travel documents, resulting in a rapid and streamlined boarding procedure.
Advanced Imaging Technology (AIT): It is a security measure utilized in airports to screen travellers for hidden objects using either millimetre wave or backscatter X-ray technology. AIT serves as a less intrusive alternative to physical pat-downs, yet it raises apprehensions regarding privacy and health. To address privacy concerns, strict protocols have been implemented, including software that obscures identifiable features and immediate deletion of images after scanning. While AIT radiation exposure is negligible and poses no immediate harm, the possible health risks cannot be disregarded. For example, individuals with medical implants such as pacemakers may need to avoid AIT scans due to potential interference.
Explosive Trace Detection (ETD): The technology of ETD is utilized for the identification of minute amounts of explosives present on various surfaces like clothing, luggage, and other objects. ETD technology proves particularly beneficial in detecting the presence of explosive particles on hands and clothing, which may indicate a recent encounter with explosives. ETD applies different techniques to collect and examine samples from suspected surfaces carrying explosive residues. One of the most common methods is swabbing, where a small cotton swab is used to collect any minute particles or traces of explosive material from the surface, which is then analysed in an ETD instrument to detect the presence of explosive residue. Another technique used to collect samples is air sampling, where an ETD instrument draws air into it through a filter to trap any particles or traces of explosive material, which is then scrutinized to identify the presence of explosive residue.
