19.50 Check and ensure the two inner mask non-return valves are in place and are seated correctly,
restow the face mask into its bag. Note: Do not attach neck loop to the retaining stud. This will
prevent the reflex seal becoming permanently distorted.
19.51 Fill out the BA tally – the pressure to be inserted is that noted in paragraph 19.43 above and
rounded down. i.e. 292 bar would be entered as 290 bar. Ensure that printed details on the BA
tally are clear and enter rank and name.
Note: if there is a leak as a result of the breathe down sequence above the wearer should operate
first breath button and repeat the ’A’ test ‘breathe down sequence’ from 19.32 above, paying
particular attention to correctly fitting the face mask onto the face and the adjustment of the head
harness. The straps should not be over tightened.
19.52 If the wearer continues to find a leak they should try another set and if there is still a leak they
should inform the OIC.
19.53 Extreme movement of the head may in some cases cause some leakage, but this should cease
once the head is returned to a more central position and/or the head movement is less severe. A
continuous leak that does not stop even when the head is in the central position is not
acceptable.
19.54 Anyone who consistently fails to get a seal with a range of standard issue face masks is to be
taken off the run and placed on light duties. OSG is to be informed as soon as possible, and will
arrange for a face fit test to be conducted and the issue of a personal issue face mask as
appropriate.
19.55 Replace Bodyguard key (if removed), check that the Bodyguard returns to the ‘battery charging’
icon.
19.56 Check if available, that the spare cylinder is correctly stowed and is within the hydraulic test date.
Note: for EDBA, check station stock.
19.57 Complete the BA log book for the BA set you are testing, record the exact pressure at the start of
the leak test and do not round down.
19.58 Please refer to the following policy numbers if BA set is fitted with radio communications.
• Policy number 516 - Entel HT981 fireground radio and Savox interface equipment
(B.A.R.I.E.).
• Policy number 592 - Breathing apparatus radio interface equipment (B.A.R.I.E.).
• Policy number 593 - Entel HT981 intrinsically safe fireground radio.
20 PSS 7000 ‘B’ test
Note: Before conducting ‘B’ test don Nitrile gloves and consider respiratory protection following
operational or real fire training use.
Frequency
20.1 A ’B’ test is to be carried out on a BA set:
(a) On receipt at station (carried out when replacement BA set is unwrapped for use).
(b) After any use (including 28 day test).
20.2 Check the front of the BA log book for the ‘do not use after’ date to ensure the BA set is still
within its certified test date and ensure this date corresponds to that on the Bodyguard display
(see 20.54).
