Abstract: An apparatus for affecting air includes a housing. The apparatus includes a treatment layer disposed in the housing for treating air. The apparatus includes a fan. The apparatus includes a gas powered motor mechanically engaged with the fan to operate the fan which forces the air through the treatment layer. The apparatus includes a compressed gas tank in fluid connection with the gas powered motor to provide gas to the motor to power the motor. A method for affecting air.

Abstract: A method for a miner in a mine to breathe in the mine having the steps of turning on an on off valve of a first air cylinder while in the mine so air flows from the first air cylinder connected to a first port of a connector to and through a third port of the connector and to a facemask on the miner's head. There is the step of the miner breathing air in the facemask from the third port. There is the step of connecting a second air cylinder to a second port of the connector. There is the step of turning on an on off valve of the second air cylinder while in the mine so air flows from the second air cylinder to and through the third port and to the facemask so the miner is breathing air in the facemask from the first and second air cylinders. There is the step of separating the first air cylinder from the first port while in the mine. A system for a miner in a mine to breathe in the mine.

Abstract: A change over station (COS) for persons in a hazardous environment includes a steel housing having only a single entrance door, a chamber, and an air lock portion. The COS includes a first elongate seat disposed in the chamber and a plurality of compressed air cylinders disposed in the seat. The COS includes plumbing connected to the air cylinders formed of gas lines and valves and an exhaust muffler including first, second and third air paths that provide air into the chamber. The third air path is door activated when the door is opened by a door activated switch. The COS includes a storage portion disposed in the housing having supplies, including water and SCSRs or SCBAs. A method for providing a protected environment to miners from a mine environment in a mine.

Abstract: A shelter to protect users from an external environment has an inner front module having an airlock and an outer front module which is slidingly attached to the inner front module. The shelter has an inner rear module and an outer rear module slidingly attached to the inner rear module. When the outer front module and the inner front module are in an extended state and the outer rear module and the inner rear module are in an extended state and the outer front module and outer rear module are attached, they form an airtight chamber in which users are protected from the external environment. A method for constructing a shelter to protect users from an external environment is also disclosed.

Abstract: An apparatus for cleaning air includes a housing having a chamber. The scrubber includes a carbon dioxide scrubber layer disposed in the chamber which claims carbon dioxide from air passing through the scrubber layer. The scrubber includes a forcing element which draws the air into the scrubber and forces the air through the scrubber layer which is powered without any electricity. A system for supporting a breathable environment for users. The system includes an enclosure. The system includes an air scrubber disposed in the enclosure which cleans carbon dioxide from air in the enclosure that is powered without any electricity. A method for cleaning carbon dioxide from air. The method includes the steps of flowing compressed air through a fluid driven motor to operate the motor without any electricity. There is the step of rotating a fan with the operating motor.
