Abstract
A breathing apparatus simulator unit (BASU) comprises a mouthpiece/noseclip subassembly and a cartridge subassembly. The mouthpiece/noseclip subassembly includes the same mouthpiece/noseclip subassembly that is utilized in an actual self-contained self-rescuer (SCSR) device. The cartridge subassembly comprises a container containing a reactionary material. The reactionary material reacts with at least one product of a user's exhalation to generate heat and resistance, thereby providing sensations to simulate the use of an actual SCSR.
Claims20
A breathing apparatus, comprising:
- a mouthpiece;
- a canister removably attached to the mouthpiece, the canister defining a first opening in direct fluid communication with the atmosphere, a second opening in fluid communication with the mouthpiece, and a flowpath extending between the first and second openings, the flow path providing fluid communication between the mouthpiece and the atmosphere;
- and
- a porous material substantially completely filling the canister and for reacting with at least one product of a user's exhalation to generate heat and resistance, thereby providing sensations to the user that simulate the use of an actual self-contained self-rescuer device, the porous material consisting of a non-hazardous material.

A breathing apparatus, comprising:
- a mouthpiece;
- a canister removably attached to the mouthpiece, the canister providing fluid communication between the atmosphere and the mouthpiece;
- and
- a non-hazardous means for generating heat and resistance in response to a user's exhalation to simulate the use of an actual self-contained self-rescuer device, the non-hazardous means being porous and substantially completely filling the canister.
