摘要： A process for converting post-explosion gases of an inhabitable level, low-oxygen ambient environment to a breathable mixture for human consumption comprises receiving a flow of post-explosion gas with oxygen, carbon dioxide, carbon monoxide, nitrogen, and methane. The oxygen, carbon monoxide, and carbon dioxide are removed from the from the flow of post-explosion gas to create both a mixture including oxygen, carbon monoxide, and carbon dioxide; and a residual stream including nitrogen and methane. The oxygen is removed from the mixture of oxygen, carbon monoxide, and carbon dioxide, and concentrated in a primary oxygen storage canister. The nitrogen is removed from the residual stream and stored in a nitrogen storage canister separate from the oxygen storage canister. The methane is vented back to the inhabitable level, low-oxygen ambient environment. The stored oxygen and nitrogen are metered through a breathing mask at a habitable level of 19-21% oxygen to a user.

摘要： A self-rescuer device comprises an intake pump that creates a gas stream. The gas stream enters a first sieve that separates carbon dioxide, carbon monoxide, and oxygen from the gas stream to create a mixture. The remaining gas stream flows to a second sieve that separates nitrogen from the remaining gas stream and vents the residual gas to outside of the self-rescuer device through a residual output. The separated mixture is directed to a gas processor separates the oxygen from the mixture. A nitrogen storage canister coupled to the separated output of the second sieve stores the separated nitrogen, and an oxygen storage canister coupled to the separated output of the first sieve stores and concentrates the separated oxygen until a purity threshold is met. Habitable nitrogen and oxygen are metered from their storage canisters and supplied to a user of the device through a breathing mask within an exterior mask shell.
