enclosing a pyrophoric workpiece in the chamber; sensing a chamber temperature within the chamber with a temperature sensor; sensing a chamber oxygen concentration within the chamber with an oxygen sensor; comparing the chamber temperature to a predetermined temperature and comparing the chamber oxygen concentration to a predetermined oxygen concentration; dispensing an antipyrophoric material onto the workpiece within the chamber if the chamber temperature meets or exceeds the predetermined temperature or if the chamber oxygen concentration meets or exceeds the predetermined oxygen concentration. ## Claims ### Claim 1 A method of using a fire suppression system, the method comprising: maintaining an inert atmosphere in a chamber; enclosing a pyrophoric workpiece in the chamber; sensing a chamber temperature within the chamber with a temperature sensor; sensing a chamber oxygen concentration within the chamber with an oxygen sensor; comparing the chamber temperature to a predetermined temperature and comparing the chamber oxygen concentration to a predetermined oxygen concentration; dispensing an antipyrophoric material onto the workpiece within the chamber if the chamber temperature meets or exceeds the predetermined temperature or if the chamber oxygen concentration meets or exceeds the predetermined oxygen concentration. ### Claim 2 (depends on 1) The method of claim 1, wherein the chamber is a glove box comprising viewing windows and a plurality of sealed glove ports positioned to enable user manipulation of the workpiece about a workspace within the chamber. ### Claim 3 (depends on 1) The method of claim 1, wherein maintaining the inert atmosphere in the chamber comprises supplying nitrogen to the chamber. ### Claim 4 (depends on 1) The method of claim 1, wherein the predetermined oxygen concentration is 15%. ### Claim 5 (depends on 1) The method of claim 1, wherein dispensing the antipyrophoric material onto the workpiece within the chamber comprises dispensing a magnesium oxide sand comprising an anticaking agent. ### Claim 6 (depends on 1) The method of claim 1, wherein dispensing the antipyrophoric material onto the workpiece within the chamber comprises at least one of: (a) creating a heat sink sufficient to reduce the predetermined temperature proximate the workpiece; and (b) creating an oxygen barrier surrounding the workpiece. ### Claim 7 (depends on 1) The method of claim 1, wherein dispensing the antipyrophoric material onto the workpiece within the chamber comprises dispensing the antipyrophoric material through a discharge nozzle in a granular sand to cover the workpiece in a substantially conical pile. ### Claim 8 (depends on 1) The method of claim 1, wherein dispensing the antipyrophoric material onto the workpiece within the chamber comprises dispensing the antipyrophoric material through a plurality of discharge nozzles in a granular sand to cover the workpiece in substantially conical overlapping piles. ### Claim 9 (depends on 1) The method of claim 1, wherein: maintaining the inert atmosphere in the chamber comprises supplying inert gas from a cabinet to the chamber through a gas emitter coupled to the chamber; the cabinet comprises a first walled compartment and a second walled compartment; the first walled compartment houses a plurality of fire suppression control systems comprising at least one of: electrical components coupled with the temperature sensor and the oxygen concentration sensor and the dispenser, and controls for at least one of (a) gas solenoids, (b) high pressure tank nozzles, and (c) the gas emitter coupled to the chamber; and the second walled compartment comprises high pressure gas components and solenoid and actuator systems. ### Claim 10 (depends on 9) The method of claim 9, further comprising supplying inert gas from the cabinet to a hopper containing the antipyrophoric material while the antipyrophoric material is dispensed onto the workpiece within the chamber. ### Claim 11 (depends on 1) The method of claim 1, wherein dispensing the antipyrophoric material onto the workpiece within the chamber comprises discharging the antipyrophoric material from a hopper attached to the chamber. ### Claim 12 (depends on 11) The method of claim 11, wherein dispensing the antipyrophoric material onto the workpiece within the chamber comprises remotely opening a valve between the hopper and the chamber. ### Claim 13 (depends on 12) The method of claim 12, wherein dispensing the antipyrophoric material onto the workpiece within the chamber comprises the temperature sensor and the oxygen concentration censor wirelessly communicating with a controller of the valve to remotely open the valve. ### Claim 14 (depends on 12) The method of claim 12, wherein dispensing the antipyrophoric material onto the workpiece within the chamber comprises gravity pulling the antipyrophoric material from the hopper through the valve to the chamber. ### Claim 15 (depends on 12) The method of claim 12, wherein remotely opening the valve comprises controlling a solenoid to open the valve.
