A method and apparatus for controlling a hazardous device

Abstract

A method of controlling a hazardous device comprising the steps of providing a combination of a barrage unit and a container for holding a liquid, the container being adapted to receive the barrage unit, the barrage unit comprising at least one pad, the pad comprising an absorbent fibrous material and an absorbent crystalline material; arranging the hazardous device and barrage unit in the container with the barrage unit at least partially covering the hazardous device; and, adding a liquid to the container so that the barrage unit absorbs the liquid.

1 . A method of controlling a hazardous device comprising the steps of:
 providing a combination of a barrage unit and a container for holding a liquid, the container being shaped as a bag adapted to receive the barrage unit, the barrage unit being shaped as a pouch for receiving the hazardous device, the pouch comprising first and second side walls, each side wall comprising a pad, each pad comprising an absorbent fibrous material and a superabsorbent polymer;   arranging the hazardous device and pouch shaped barrage unit in the container with the hazardous device with the pouch shaped barrage unit;   adding a liquid to the container so that the barrage unit absorbs the liquid.   
     
     
         2 . A method as claimed in  claim 1 , wherein each pad is sandwiched between first and second liner layers of a respective one of the first and second side walls. 
     
     
         3 . A method as claimed in  claim 1 , wherein the liquid is added to the container before the step of arranging the hazardous device and pouch shaped barrage unit in the container. 
     
     
         4 - 11 . (canceled) 
     
     
         12 . A method as claimed in  claim 1 , wherein the superabsorbent polymer is one or more polyacrylate or polyamide. 
     
     
         13 . A method as claimed in  claim 12 , wherein the one or more polyacrylate or polyamide is one or more polyacrylate salt or polyamide salt. 
     
     
         14 . A method as claimed in  claim 1 , wherein the fibrous material is a cellulosic material. 
     
     
         15 . A method as claimed in  claim 2 , wherein each of the liner layers comprises a hydrophilic material. 
     
     
         16 . An apparatus for controlling a hazardous device comprising:
 a pouch shaped barrage unit comprising first and second side walls, each sidewall comprising a pad, each pad comprising an absorbent fibrous material and a superabsorbent polymer; and   a container for holding a liquid, the container being dimensioned to receive the barrage unit.   
     
     
         17 - 20 . (canceled) 
     
     
         21 . A method as claimed in  claim 13 , wherein the one or more polyacrylate salt or polyamide salt is one or more polyacrylate metal salt or polyamide metal salt. 
     
     
         22 . A method as claimed in  claim 21 , wherein the metal of the one or more polyacrylate metal salt or polyamide metal salt is sodium or potassium. 
     
     
         23 . A method as claimed in  claim 14 , wherein the cellulosic material is pulp fibre. 
     
     
         24 . A method as claimed in  claim 15 , wherein the hydrophilic material is cotton. 
     
     
         25 . An apparatus as in  claim 16 , wherein each pad is sandwiched between first and second liner layers of a respective one of the first and second side walls. 
     
     
         26 . An apparatus as in  claim 25 , wherein each of the first and second liner layers comprises a hydrophilic material. 
     
     
         27 . An apparatus as in  claim 26 , wherein the hydrophilic material is cotton. 
     
     
         28 . An apparatus as in  claim 16 , wherein the superabsorbent polymer is one or more polyacrylate or polyamide. 
     
     
         29 . An apparatus as in  claim 28 , wherein the one or more polyacrylate or polyamide is one or more polyacrylate salt or polyamide salt. 
     
     
         30 . An apparatus as in  claim 29 , wherein the one or more polyacrylate salt or polyamide salt is one or more polyacrylate metal salt or polyamide metal salt. 
     
     
         31 . An apparatus as in  claim 30 , wherein the metal of the one or more polyacrylate metal salt or polyamide metal salt is sodium or potassium. 
     
     
         32 . An apparatus as in  claim 16 , wherein the absorbent fibrous material is a cellulosic material.
