System for facilitating safe transfer of hazardous material

摘要

A sealed system for facilitating the safe transfer of hazardous material through a port in the floor of a containment enclosure to an open topped storage container positionable in precise axial alignment below the port and supported on a lift cart for vertical movement toward and away from the port. The port is defined by a vertically depending flange or enclosure ring in the floor of the containment enclosure and is closeable by a seal cover within said containment enclosure positionable for sealing engagement with the periphery of the port. The port is also closed alternately by a sturdy plastic bag supported from a seal ring engageable in leak-proof sealed relation with the port and partially contained within the storage container supported on the lift cart. A succession of bags are positioned under the port, elevated into sealed relation with the port, filled, sealed shut, severed from the sealed port and lowered and removed for permanent storage.
