Federal security workers in the US have started using hand-held scanners to inspect bottled carry-on liquids for explosives at some of the country's busiest airports, the government said today.
The Transportation Security Administration has finished testing the device at Miami International Airport and Newark Liberty International Airport.
Testing is ongoing in Los Angeles, Detroit and Las Vegas, said agency spokesman Nico Melendez. Testing begins in Boston tomorrow.
TSA expects to deploy about 200 of the devices at a number of airports around the US by October, Melendez said.
The technology, which detects explosive material in sealed bottles of liquid, is only used on passengers selected for secondary inspections before boarding.
