TSA announces influx of puffer machines at airports
WASHINGTON (AP) -- The busiest U.S. airports -- about 40 of them -- will have bomb-detection equipment known as "puffer machines" installed by spring, the Transportation Security Administration said Monday.
There are now 24 airports with the walkthrough machines, which puff air onto a person to dislodge tiny particles from skin and clothing. The machine sucks up the particles and then analyzes them for traces of explosives.
One of the biggest weaknesses in U.S. airport security has been the limited ability to detect bombs on passengers. Government screeners have relied largely on patdowns, which are unpopular, time-consuming and incomplete.
In contrast, a puffer machine takes 17 seconds to check a passenger and can analyze particles as small as one-billionth of a gram.
"It's more comprehensive and more accurate and it limits the number of patdowns," said TSA spokesman Darrin Kayser.
Puffer machines were installed Monday at Washington's Dulles International and Reagan National airports.
