A method and device for suppressing an electrical fire within an electrical wire carrying conduit. The device is a flexible receptacle containing an admixture of super absorbent polymer and water having substantially superior fire suppression and extinguishing properties that does not provide an electrically conductive environment. The receptacle is drawn though a conduit either before or after wires have been placed in the conduit, and the filled with the admixture. A sleeve may be placed over the receptacle to prevent breaching of the receptacle during installation. Once the receptacle and admixture is positioned within the conduit, should arcing or a buildup of heat occur, the receptacle will rupture and the admixture will cover the specific area. These particular properties and ratios of the admixture will enable electrical fires to be extinguished more rapidly and not flare back up. The admixture further encapsulates noxious and toxic gases associated with electrical fires.
