ABSTRACT:
A facility for providing a sealed work area to handle, manipulate and formulate materials which includes a walled enclosure having an interior periphery defining a work area. The enclosure includes an inlet port for allowing air to flow into the enclosure work area and an outlet port for allowing air to flow out of the enclosure work area. A replaceable liner is positioned within the enclosure work area in facing relationship with the interior periphery to further define the enclosure work area. The liner includes an inlet aperture in complementary sealed engagement with the inlet port and an outlet aperture in complementary sealed engagement with the outlet port. The liner is readily removable from the work area to be replaced with a second liner to facilitate decontamination of the work area. A blower causes air to flow through the inlet port into the enclosure work area and out of the enclosure work area through the outlet port.
