Traveling through airport security can be stressful and confusing. As you make your way through the security checkpoint, a TSA agent may randomly select you for additional screening. This screening includes a chemical test where the agent wipes your hands with a cloth or paper, and then places it in a machine for analysis.
If you’re wondering why the TSA is swabbing your hands, read on to learn the reasons behind this common security procedure.
If you’re short on time, here’s a quick answer: The TSA wipes travelers’ hands to test for explosive materials and ensure flight safety.
Testing for Traces of Explosives
The Transportation Security Administration (TSA) has implemented various security measures to ensure the safety of air travel. One of these measures involves testing passengers’ hands for traces of explosives.
This process, known as Explosive Trace Detection (ETD), is conducted using specialized machines designed to detect even the tiniest amounts of explosive materials.
How the ETD Machines Work
The ETD machines used by the TSA are highly sophisticated and sensitive devices. They work by collecting a sample from the passenger’s hands using a swab. This swab is then inserted into the machine, which analyzes the sample for the presence of explosive residue.
The machines use advanced technology, such as ion mobility spectrometry, to detect and identify any traces of explosives.
The ETD machines are calibrated to detect a wide range of explosive materials, including those commonly used in terrorism, such as nitroglycerin, TNT, and C-4. These machines are regularly tested and maintained to ensure accurate results.
Why Hands are Tested
Testing passengers’ hands for traces of explosives is an important part of the TSA’s security protocol. While it may seem unusual or inconvenient, this measure is crucial for preventing potential threats from boarding airplanes.
The hands of passengers come into contact with various surfaces, including luggage, personal belongings, and potentially explosive materials. By swabbing passengers’ hands, the TSA can identify any suspicious residue that may indicate the presence of explosives.
Moreover, testing hands is a non-invasive method that allows the TSA to quickly and discreetly screen a large number of passengers. It is a more efficient alternative to conducting extensive pat-downs or using invasive body scanners.
Common Materials Detected
The ETD machines used by the TSA can detect a wide range of materials that may be associated with explosives. Some common materials that can be detected include:
- Chemical explosives
- Residues from explosive devices
- Detonators and fuses
It is important to note that the presence of these materials does not necessarily mean that a passenger is carrying explosives. The machines are highly sensitive and can detect even trace amounts of residue.
In some cases, the detected residues may be harmless, such as residues from cleaning products or certain medications. However, the TSA takes every precaution to thoroughly investigate any positive results and ensure the safety of all passengers.

Ensuring Flight Safety
When it comes to air travel, safety is of utmost importance. The Transportation Security Administration (TSA) plays a crucial role in ensuring the safety of passengers and crew members onboard. One of the measures they employ is the practice of wiping passengers’ hands during the security screening process.
This seemingly simple action serves several important purposes.
Part of Overall Security Screening
Wiping passengers’ hands is just one part of the comprehensive security screening process implemented by the TSA. It is designed to detect any potential threats or prohibited items that may be present on a person’s hands.
By doing so, the TSA can identify any suspicious substances or residue that could pose a risk to the aircraft and its occupants.
During the screening, a TSA officer will use a swab to collect a sample from a passenger’s hands. This sample is then analyzed using specialized equipment to detect the presence of explosives or other dangerous substances.
This method enables the TSA to identify and prevent potential threats before they can harm the passengers and crew.
Deterring Would-Be Attackers
By incorporating hand-wiping into the security screening process, the TSA aims to deter individuals who may be planning to carry out an attack. The knowledge that their hands will be tested for traces of dangerous substances acts as a deterrent to potential attackers.
This additional layer of security helps to safeguard the entire aviation system.
Furthermore, the act of hand-wiping sends a strong message to would-be attackers that the TSA is proactive in its efforts to prevent any threats from entering the aircraft. This can discourage individuals from attempting to bring hazardous materials or weapons on board, as they are more likely to be caught during the screening process.
Reassuring the Public
Another important aspect of hand-wiping is its role in reassuring the traveling public. By witnessing the thoroughness of the security screening process, passengers can feel confident that every precaution is being taken to ensure their safety.
This helps to alleviate any concerns or anxieties they may have about flying.
The TSA’s commitment to employing innovative and effective security measures, such as hand-wiping, helps to maintain public trust in the aviation industry. It demonstrates that the authorities are actively working to stay one step ahead of potential threats, making air travel safer for everyone.
