7.6 Functional testing
Before releasing the breathing apparatus for use, perform the functional testing
to ensure the integrity of the breathing apparatus and the correct function of the
second medium-pressure connector.
WARNING
Failure of the breathing apparatus to meet any of the standards or
parameters described in the functional tests indicates a system fault.
Do not release the breathing apparatus for use until the fault condition
is rectified.
NOTICE
Test the breathing apparatus in the normal operating position (vertical).
Connecting a decontamination air supply with the apparatus in a
horizontal position may activate the warning whistle of the breathing
apparatus. If this occurs, disconnect the decontamination air supply,
allow the system to fully vent and then reconnect with the breathing
apparatus in a vertical position.
1. Prepare the breathing apparatus and lung demand valve for use, but do not
connect a face mask. Carry out the leak test described in the functional
testing of the breathing apparatus (see the instructions for use supplied with
the breathing apparatus).
Continue with the remainder of the testing for inlet or combined connectors only.
2. Slowly and fully open the cylinder valve of the breathing apparatus.
3. Disconnect the protection cap from the inlet connector of the second
medium-pressure connector and connect the hose from the
decontamination air supply.
4. Open the valve of the decontamination air supply.
5. Close the cylinder valve of the breathing apparatus.
WARNING
Do not direct air flow from the outlet of the lung demand valve toward
the face, eyes or skin. Released air can cause serious injuries.
6. Activate an unobstructed air flow from the outlet of the lung demand valve
as follows:
a. Positive-pressure lung demand valve – Press the centre of rubber
cover.
b. Negative-pressure lung demand valve – Press and hold the centre of
the rubber cover.
7. The breathing apparatus pressure gauge reading will fall to zero pressure,
but decontamination air must continue to flow.
8. Switch off the air flow from the lung demand valve.
NOTICE
The warning whistle of the breathing apparatus must be silent.
9. Close the valve of the decontamination air supply then disconnect the
decontamination hose from the connection of the second medium-pressure
connector.
10. Following satisfactory testing, fit all protection caps and store the apparatus
ready for use.
