Abstract
A mechanical apparatus for training is disclosed that reduces the flow of r or oxygen in an oxygen breathing apparatus (OBA) to simulate the effects of an empty oxygen canister. A timer mechanism is coupled to a butterfly valve in the air passageway of the OBA. After a preselected period of time that corresponds to the alarm setting on an operational OBA that signifies a low-oxygen status, the timer mechanism begins to wind the valve into its closed position.
