Abstract: A method for sealing a vent includes coupling a film including an adhesive surface to an applicator, applying the film onto the vent using the applicator adhering the adhesive surface to at least one of the vent and a portion of a structure surrounding the vent, and decoupling the film from the applicator during or after the applying the film. An applicator for applying a sealing film to a vent for sealing the vent includes a first elongate member, a second elongate member having a bore extending along its length and receiving the first member within the bore, where the first elongate member is longer than the second elongate member and where a first end portion of the first elongate member extends beyond a first end of the second elongate member and a second end portion of the first elongate member extends beyond a second end of the first elongate member, and where the second elongate member is rotatable to various orientations relative to the first elongate member about a longitudinal axis.

Abstract: A portable enclosure, easily erectable and collapsible, to provide environment control and prevent contaminants from being released from the enclosure. The enclosure provides a flexible envelope attached to the interior of the space defined by vertical and horizontal supports which can be erected and collapsed. When erected the enclosure functions as an anteroom and has removable panels in the sides and top. In use, the enclosure is sealed against a vertical or horizontal surface to be worked on and a panel from the side of the enclosure is opened and closed to provide access to the surface by the user. When collapsed the enclosure is a package approximately the size of an average golf club bag which is easily portable to another location. Ducting is provided to which negative pressure pumps are connected to maintain negative pressure within the enclosure and draw contaminants into the pump and then into a closed container.
