Abstract
An encapsulating system for abating and mitigating contamination from lead-based dust, particles and/or chips in a construction repair, renovation or removal operation and thereby minimizing exposure to lead-based hazardous materials is provided. The apparatus utilizes a framing mechanism supporting an encapsulator container or workbag adapted to surround and seal off a work-area encompassing a contaminated work-piece. The framing mechanism is typically adjustable poles or an adjustable frame apparatus having a plurality of height adjustable vertical legs. The flexible plastic encapsulating container is positioned and supported by the adjustable poles or frame. The container has at least one open-end for surrounding the contaminated work-piece, and the open-end of the container is adhered to the work-area and substantially surrounds and seals off the contaminated work-piece from the interior portions of the work site.
