in lieu of typical operational systems. The invention contemplates the modification or replication of the oxygen generating canister of the operational OBA, converting it into a flow-through system of filtering layers and chemically converting, absorbing and reacting layers. Together the layers are affective to convert carbon monoxide to carbon dioxide and react with the carbon dioxide to form calcium carbonate. Alteration also is made to the breathing bags such that the supply of breathable air is communicated by tubular conduit from the simulated generator to the user, and the user's exhaled breath is directed into the bags to provide the inflation the bags need for realism in feel and appearance.
