A method of forming a safer and more secure containment for the removal or isolation of harmful and/or noxious particulate materials. The containment is formed using adhesive coated plastic sheeting to form an isolated enclosure. The adhesive holds the sheeting under negative pressure and is removable with minimal damage or transfer to wall and floor surfaces.
