发明名称 Negative air bag
摘要 A hazardous waste removal assembly includes a generally rectangular flexible bag having a front panel and a back panel joined at a lower portion of the bag to form a collection chamber. The bag is sealed such that it is impermeable to dust and other particulate matter. The assembly also includes at least one glove sleeve fashioned through the front panel of the bag to permit an operator to remove abestos from a segment of the enclosed conduit, while maintaining subatmospheric air pressure within the bag. A replacement air intake inlet valve is positioned on the front or back panel to permit the ingress of ambient air into the bag while concomitantly preventing egress of air or particulate contents out of the bag.
