ABSTRACT:
A personal liquid chemical agent detector incorporating a sensor which changes resistance in response to contact with liquid, first and second switches which function as pins for attaching the detector to the wearer and as electrical switches, a battery, a resistor, and a detector and alarm circuit. A conductor incorporating a resin, conductive flakes and dye crystals selected which are solvent in selected chemical agents. A conductive paint incorporating a resin, conductive flakes a dye solution including one or more volatile solvents and a plasticizer. The invention overcomes the problem of requiring additional switches for manual testing of the detector and battery prior to use and for disconnecting the battery after use at times the detector is removed by the wearer. The invention further overcomes the problem of independent verification of detection by providing a conductor with concurrent electrical and visual appearance responses to selected chemical agents absorbed by the conductor.
