How next-gen airport scanners are ending the 100ml liquid rule


Imagine this: you wait in line to go through airport security, you hastily put your liquids in a clear plastic bag, and then you see it. Your expensive bottle of sunscreen is still in your carry-on and is now going in the trash before it’s even been opened. As you do the walk of shame to throw it away, you wonder if the pharmacy near the hotel stocks the same.

Travelers no longer have to worry; a new generation of airport scanners ends the sixteen-year ban on liquids over 100ml. Cutting-edge technology is already in place at Shannon Airport, which notably implemented the $2.7 million systems earlier this month.

Changing rules

Shannon is not alone, with other airports in the UK, Europe and North America set to roll out similar scanning equipment throughout the year. The equipment also scans laptops, phones and larger cameras, allowing them to stay inside carry-on baggage without being separated, simplifying the security process for travellers.

Heathrow Airport has been testing the equipment since 2019, with full deployment scheduled for December 1, 2022. Business tripCOO Chris Garton praised the new technology:

“This state-of-the-art kit will not only keep the airport safe with the latest technology, but also allow our future passengers to stay focused on their journey and spend less time preparing for security screening.”

The TSA has already spent $781.2 million on an order for more than 1,000 scanners, ready to go into service this summer. Talk to euro newsTSA Administrator David Pekoske called the move “an important step in improving aviation security,” adding:

“They provide our dedicated frontline officers with one of the best tools available to screen passengers’ carry-on baggage and also improve the passenger experience by allowing passengers to keep more items in their carry-on baggage during the journey. control process.

How do they work?

Using CT technology, the new scanners create a 3D x-ray of the contents of a bag, with security personnel able to check prohibited items in more detail. “Sophisticated algorithms” are used to detect weapons and explosives, an upgrade to current security equipment at airports.

The TSA website describes the new equipment as follows:

“CT technology enables better detection of threatening elements. Like existing CT technology used for checked baggage, the machines create such a clear picture of a bag’s contents that computers can automatically detect explosives, including liquids. Going forward, the goal is to keep laptops and 3-1-1 liquids inside the bag during checkpoint screening. According to current screening procedures for this technology, laptops are allowed to remain inside the bag for screening.

Restrictions on liquids have been in place since 2006, after a foiled terrorist plot to bomb several planes between the UK and North America. Currently, the maximum liquid allowance is 100ml, which must fit in a clear plastic bag and be presented separately at security.
