Abstract
A process, and apparatus for practicing the process, for removing hazardous material collected on a cleanable HEPA filter in a manner which protects operating personnel from exposure to that hazardous material comprising use of a bag composed of high efficiency filter material, the bag being positioned within a vacuum container having a removable lid. The bag has an open top which extends out of the container during the cleaning operation, the container being closed by a removable lid. The system allows the lid to be removed and the bag sealed and extracted from the container without shutting off the vacuum generated flow of air.
