Disintegration of sensitive information
WHITEMAN AIR FORCE BASE, Mo. -- Airman 1st Class Jonathon Crist, 509th Security Forces Squadron, assists with destroying documents in a disintegrator Oct 26. As waste is fed into the unit, it falls down a chute into a destruction chamber which contains a rotor with five knives mounted to it. The five rotating knives pass by two stationary bed knives and cut the waste smaller and smaller with each pass. The size of the final waste is determined by an interchangeable security screen. Once the waste is small enough to pass through the screen it drops out of the destruction chamber and is moved into a waste collection bin. (U.S. Air Force photo/Maj. Joe DellaVedova)
