What does it mean when a TSA agent rubs your hands?
Going through airport security can be a nerve-wracking experience for many of us. Especially when you are careful to follow the rules, like the liquids rule, and suddenly, a TSA agent approaches to rub your hands. This situation can raise questions, but what does this procedure actually mean? Let’s explore the reasons behind this unexpected check.
The reasons behind the hand rubbing
When the TSA agent rubs your hands, they are actually looking for traces of explosive materials. This procedure involves collecting small samples from your skin to test them in a device called a ion mobility spectrometer. If residues of substances like glycerin, nitroglycerin, or nitrates are detected, it may trigger a secondary check, but don’t worry, it doesn’t necessarily mean you’re in trouble.
Concerning positive results
A positive test for explosive substances can seem alarming, but it can often be explained by entirely mundane reasons. For instance, these substances are frequently found in cosmetics, soaps, or shampoos. If you used these products before passing through security, there may be traces left on your hands. Additionally, a simple mistake like not washing your hands properly after using the restroom can also cause a false alarm.
Items of concern
In addition to your hands, security agents may also examine other items in your possession. For example, if you have shoes that have come into contact with fertilizers or other similar materials, this can also trigger an alarm. Equipment such as golf clubs or hiking poles can also retain these residues, as they are often used in environments that might expose them to these substances.
How to avoid the rubdowns
To minimize the chances of this unwanted attention, there are a few simple precautions to take. When washing your hands, be sure to rinse them thoroughly, and consider using a hand sanitizer that does not contain glycerin. If you have been in areas where fertilizers have been used, a quick wipe of your shoes before reaching the airport can make all the difference. Ultimately, a secondary check is not a cause for anxiety, but just a minor inconvenience that requires a little patience and may prolong your time at the security desk.
Transition with humor
Think about it: this might be the only time in your life when having your hands rubbed has nothing to do with a romantic date! So the next time a TSA agent approaches you with swabs, take a deep breath and enjoy the “incredibly trivial” side of airport security.
