ABSTRACT:
A negative pressure method and apparatus for protection from airborne asbestos and other particulate contamination is disclosed, including an enclosure with doorways and decontamination chambers with an air intake through the decontamination chambers with at least one filtration unit flow connected with the enclosure, with a blower to pull air into the filtration unit and dispelling the filtered air to the atmosphere. A high volume air flow intake is maintained with a significant negative air pressure in the enclosure. A filtration device is provided with multiple entrance ports providing for a large flow of air through the body of the room together with individual entrance ports to receive the discharge from separate vacuum cleaners.
