Airport screening is designed to detect threats and prohibited items, such as weapons, chemicals, and liquids. Screening equipment includes metal detectors, millimeter wave machines, backscatter X-ray scanners, and cabinet X-ray machines. While older body scanners may have shown detailed images of a person's body, including sensitive areas, newer machines use privacy protections, such as generic body outlines, to safeguard passenger privacy. Passengers with medical devices, bandages, or support appliances should inform TSA officers before screening and may be subject to additional screening procedures, such as pat-downs or X-ray screening of the device.

What You'll Learn
Metal detectors and full-body scanners
Metal detectors use magnetic fields to identify metal objects. When metal is present, the machine's magnetic field is reflected back, triggering an alert for the operator. These machines are sensitive enough to detect items such as belt buckles and watches but will ignore small amounts of metal, like buttons or earrings. Walk-through metal detectors (WTMD) are commonly used in airports as part of the security screening process.
Full-body scanners, also known as advanced imaging technology (AIT), use non-ionizing radiofrequency waves or X-rays to detect potential threats. Millimeter-wave scanners emit low-energy waves, similar to cell phone radiation, and capture the reflected energy. These scanners can detect both metallic and non-metallic items, including weapons and explosives. The scanners generate generic body outlines and indicate the location of any detected items. While older versions of these scanners raised privacy concerns by revealing detailed body images, newer machines now blur faces and use generic body outlines to protect passenger privacy.
If an individual has a bandage, compression sleeve, or dressing, prosthesis, cast, or support brace, they must inform the TSA officer before screening. These items may require additional screening, including inspection, handheld metal detector screening, and testing for any traces of explosives. Passengers may also request a private screening with a companion if needed.
It is important to note that TSA officers may also perform pat-downs as part of the security measures. These pat-downs can include inspections of sensitive areas, and officers use the back of their hands for these sensitive areas. Passengers may be asked to adjust their clothing during the pat-down, and officers will explain the procedure beforehand.

Informing TSA officers about bandages
It is important to inform TSA officers about any bandages, compression sleeves, or dressings before the screening begins. This is because these items are subject to additional screening procedures.
If you are wearing a bandage, you may be asked to conduct a self-pat-down of the area outside of your clothing. You may also be required to undergo a hand-held metal detector screening and a test of your hands for any trace of explosives. If you have a bandage that is bulky or covers a large area of your body, it is advisable to inform the TSA officer about it in advance, so they can guide you through the screening process.
TSA officers are trained to assist passengers with medical conditions or disabilities. Before the screening begins, inform the officer about any external medical devices, prostheses, casts, support braces, or slings you may be using. If you have a bandage that is attached to a medical device, you can still be screened without exposing it. However, if additional screening is required, you may be asked to conduct a self-pat-down of the device outside your clothing, and your hands may be tested for traces of explosives.
It is important to note that you have the right to request a private screening, where a companion of your choice can accompany you. A second officer of the same sex will always be present during private screenings. If you have any concerns or special requirements, it is advisable to contact the TSA ahead of time to make the necessary arrangements.
By following these guidelines and informing TSA officers about your bandages or medical conditions, you can ensure a smoother screening process and receive the assistance you may need during your travel journey.

Additional screening procedures
If you are wearing a bandage, compression sleeve, or dressing, you must inform a TSA officer before the screening begins. Your bandage will be subject to additional screening procedures, which may include:
- Inspection: A visual inspection of the bandage.
- Hand-held metal detector screening: A TSA officer will use a hand-held metal detector to scan the bandage for any metallic objects.
- Explosive trace detection: You may be asked to conduct a self-pat down of the bandage, and your hands will be tested for any traces of explosives.
- X-ray screening: If you are wearing a prosthesis, cast, support brace, or sling, you may voluntarily remove it and submit it for X-ray screening.
If you are travelling with medically necessary items, such as ice packs or gel packs, these may be presented at the screening checkpoint in any state (frozen, partially frozen, or melted). All items, including associated supplies such as IV bags, pumps, and syringes, must be screened before they are permitted into the secure area of the airport. TSA officers may test liquids for explosives or prohibited items. If they are unable to clear these items using screening technology, you may be asked to open them for vapor analysis.

Privacy concerns
Older versions of body scanners, which used backscatter technology, were known to generate detailed images of passengers' bodies, including sensitive areas like genitalia, breasts, and buttocks. This raised concerns about passenger privacy, as officers could view these images. In response, the Transportation Security Administration (TSA) implemented several measures to address these concerns. They introduced technology that blurs faces, softens images, and displays a generic body outline instead of a unique image. Additionally, they separated the officers viewing the images from those interacting with passengers and prevented scanners from saving or exporting images.
However, there have been reports of tens of thousands of scanner images being improperly saved and disseminated, raising doubts about the effectiveness of these privacy measures. Concerns have also been expressed about the potential health risks associated with ionizing radiation used in some screening equipment, although the amount of radiation exposure is said to be very low.
To protect their privacy, passengers can refuse to go through full-body scanners. In such cases, alternative screening protocols, such as a full-body pat-down, will be employed. Passengers with medical conditions or devices, such as bandages, casts, prosthetics, or catheters, should inform TSA officers before screening and may be subject to additional screening procedures like hand-held metal detector screening or explosive trace detection testing.
Overall, while airport screening procedures have evolved to address privacy concerns, the balance between security and privacy remains a delicate issue, and further improvements may be needed to fully protect passengers' privacy.

Health risks
Bandages are an essential medical supply for any first aid kit and can be used to treat a variety of different injuries. They are typically used to cover wounds to keep them clean, germ-free, and protected. This helps to prevent infections and further injury, and may also be more comfortable than leaving a wound uncovered.
However, there are some health risks associated with bandages that should be considered. Firstly, it is important to use the correct type of bandage for the specific injury and body part. An incorrect application of a bandage can potentially lead to further harm to the patient. For example, certain bandages are designed specifically for snake bites, and applying a bandage incorrectly in this situation could be dangerous. Similarly, pressure ulcers on the heels are often left open to dry, so applying a bandage in this case could be detrimental to the healing process.
Another potential health risk associated with bandages is the risk of infection. While bandages are intended to protect wounds from external influences, dirt, and bacteria, they must be changed regularly to maintain hygiene. It is recommended to change adhesive bandages daily or after they get wet. If a wound is taking an unusually long time to heal, it could be a sign of an underlying issue such as diabetes mellitus, an impaired immune system, or blood circulation problems, and a doctor should be consulted.
When travelling with a bandage, it is important to be aware of airport screening procedures. Bandages may be subject to additional screening, including inspection, hand-held metal detector screening, and testing for traces of explosives. This may include a pat-down procedure by a TSA officer, which will be conducted by an officer of the same sex. While the risk of health effects from airport screening equipment is very low, individuals with concerns about their medical condition can inform a TSA officer before screening begins and may be able to undergo alternative screening procedures.
