ABSTRACT:
A respirator, comprises, a housing having a wall with a sealable opening which is advantageously located in a cover of the housing. A chemical cartridge is disposed in the housing and it has a material capable of generating oxygen upon being started. A breathing tube is connected into the cartridge along with a breathing bag so that a person's respiratory gases may be directed into the cartridge to the bag and then back through the material of the cartridge which also advantageously retains the CO.sub.2 and enriches the respiratory gas with oxygen. A first starter is associated with the cartridge for starting the material so that it generates oxygen and a second control element is disposed in the container adjacent the sealable wall and it has a starting material therein which may be actuated to generate oxygen so as to provide an indication of whether the oxygen-generating material is operating properly and can perform its function.
