Abstract
Disclosed are methods for treating hazardous materials, such as those which result from an unwanted spill or leak, which comprise one or more of the steps or effects of: neutralizing the dispersed material; solidifying the dispersed material; immobilizing the material; and/or reducing the evolution of harmful or unwanted gaseous forms from the spillage, preferably using a binding agent which comprises a polyacrylate-polyacrylamide cross-linked copolymer.
Claims14
A composition for treating hazardous material containing acidic material comprising a binding agent and a carrying agent for delivering said binding agent to the hazardous material, said binding agent comprising at least one cross-linked copolymer comprising acrylamide units and acrylate units.
A system capable of treating acid-containing hazardous material, said system comprising binding agent and means for delivering said binding agent to the area of the hazardous material, said binding agent comprising a cross-linked copolymer comprising acrylamide units and acrylate units.
A system capable of treating acid-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.
A system for suppressing the spread of an acid-containing hazardous material, said system comprising:
- a container having an interior portion and an exterior side, said interior portion being adapted to receive a propellant;
- a propellant in fluid communication with said interior portion;
- a nozzle disposed on said exterior portion and in fluid communication with said interior portion;
- and
- a binding agent disposed within said interior portion or said nozzle.
