主权项

1. A system capable of treating hydrogen fluoride-containing hazardous material, said system comprising: binding agent; carrying agent for carrying said binding agent to the area of the hazardous material, said carrying agent comprising a fabric carrying or made from said binding agent; a discharge chute capable of holding said fabric; and means for propelling said fabric to the site of the hazardous material from a safe distance therefrom such that the fabric comes in contact with at least a portion of said hazardous material and wherein said binding agent reduces the risk from said hazardous material, and wherein said binding agent comprising a cross-linked copolymer comprising acrylamide units and acrylate units.
