Abstract:
1. A process for removing particulate matter from a building structure, said building structure having floors, walls and ceilings with particulate matter contained therein, comprising the steps of: applying foam to a portion of said building structure having particulate matter therein to thoroughly isolate said particulate matter in said portion with said foam, said foam being chemically non-reactive with said particulate matter; removing said particulate matter from said portion of said building structure while said foam remains flowable and maintains isolation of said particulate matter; moving said foam-isolated particulate matter which has been removed toward a container while maintaining isolation of said particulate matter only by the presence of said foam on said particulate matter; placing said foam-isolated particulate matter which has been removed into a container; and sealing said container so as to continue isolation of said foam-isolated particulate matter, wherein neither a baffle nor a vacuum is necessary to prevent said particulate matter from becoming airborne during removal.
