Explosives Trace Detection

Innovation & Technology

Explosives Trace Detection (ETD) is technology used at security checkpoints around the country to screen carry-on baggage and passengers for traces of explosives. Officers may swab a piece of luggage or passenger hands and then use ETD technology to test for explosives. The swab is placed inside the ETD unit which analyzes the content for the presence of potential explosive residue.

TSA is expanding its use of ETD technology in airports as part of our layered approach to aviation security and to keep passengers safe.

Passengers may experience screening of their hands using an ETD swab at airports. This additional screening measure could take place at the security checkpoint, in the checkpoint queue, or boarding areas. To ensure the health of travelers, screening swabs are disposed of after each use. Since ETD is used on a random basis, passengers should not expect to see the same thing at every airport or each time they travel.
