CHICAGO — You may get your hand swabbed the next time you take a flight out of O’Hare or Midway.
TSA security agents have been swabbing luggage for years for signs of explosives, and now they are going to start doing it to people.
The increased swabbing was ordered by Homeland Security Secretary Janet Napolitano as part of a suite of measures to improve airport security.
The swab contains a chemical that can detect traces of explosive materials.
The measure could take place when you check in, when you pass through security or at the boarding gate.
TSA is expanding the way it screens for explosives following the failed attempt to blow up a flight into Detroit on Christmas Day.
