4.5.1.1 Alternative leak test
Carry out an alternative leak test if the lung demand valve remains connected to
the SCBA and the mask:
1. Close the cylinder valve.
2. Empty the system of all air by breathing and perform the leak test.
3. Re-open the cylinder valve.
4.5.2 Mask with other connections
The masks with PE, ESA, and RA-type connectors can be tested in two ways:
– with connected lung demand valve or respiratory filter
– without lung demand valve or respiratory filter. However, this test does not
include checking if the mask/lung demand valve or mask/respiratory filter
connection is tight.
4.5.3 With connected lung demand valve or respiratory filter
4.5.3.1 Mask with PE or RA-type connector
1. Screw the lung demand valve or respiratory filter into the connector until
they are tight. Have a second person check the tightness and correct
connection.
2. Close the medium-pressure hose with your thumb or close the filter opening
with the ball of your hand.
3. Inhale and hold your breath. There must be no noticeable air ingress,
otherwise check the mask fit. The exhaled air must be able to escape
without obstruction through the exhalation valve.
4. Repeat the seal test twice.
5. If necessary, connect the SCBA or the airline equipment.
4.5.3.2 Mask with ESA-type connector
1. Insert the lung demand valve into the connector or screw in the respiratory
filter until it fits tight.
2. To check that it fits tightly, twist and pull the lung demand valve. Have a
second person check the tightness and correct connection.
3. Close the medium-pressure hose with your thumb or close the filter opening
