Use of explosive detection tech to be expanded at US airports

8220;Explosive Trace Detection technology is a critical tool in our ability to stay ahead of evolving threats to aviation security,8221; said Transportation Security Administration TSA Acting Administrator Gale Rossides.

8220;Expanding the use of this technology at checkpoints and at departure gates greatly enhances security to keep the traveling public safe,8221; he said.

Since the Christmas Day failed attack TSA has increased its random use of ETD technology within security checkpoints to screen passengers8217; hands and carry-on luggage.

In addition,TSA piloted the use of ETD technology in both the checkpoint queue and boarding areas for two weeks at Raleigh-Durham International Airport,Hartsfield-Jackson Atlanta International Airport,Orlando International Airport,and Pitt-Greenville and Coastal Carolina Regional Airports in North Carolina,a statement said.

The TSA said passengers can now expect to see the increased random use of ETD technology in areas where screening is conducted such as security checkpoints as well as in the checkpoint queue,and boarding areas.

Officers may swab a piece of luggage or passengers8217; hands,then use ETD technology to test for explosives.

The swab is placed inside the ETD unit which analyses the content for the presence of potential explosive residue.
