ABSTRACT:
A method for isolating a work object to achieve a predetermined operational objective, the method including the steps of encapsulating at least a portion of the work object in a housing in a work position so as to establish a zone of isolation relative to the portion of the work object; releasibly interconnecting the housing and the portion of the work object so as selectively to maintain said zone of isolation for a period of time sufficient to achieve the predetermined operational objective; and occluding an area proximate to the housing to resist incursion into the area during the period of time. An apparatus for isolating a work object, the apparatus including a housing having an interior dimensioned to permit the housing to be disposed in a work position with the work object received in the interior of the housing; and means for retaining the housing in the work position.
