(2) Inspect the high pressure relief valve for damage. a) Ensure the relief valve is not damaged and that the relief valve ports are not showing. b) If damaged, remove the SCBA from service. (3) Push the quick connect coupling onto the cylinder valve adapter until an audible snap is heard. The handgrip will rapidly rotate approx. 45° counter clockwise indicating that the valve is connected to the pressure regulator. Cylinder and Valve Assembly (1) Check the hydrostatic test date on the cylinder approval sticker located on the cylinder neck. Carbon-wrapped cylinders must be tested every five years. (2) Ensure the needle and gauge face on the cylinder valve gauge are clearly visible and that the gauge stem is not bent. (3) Ensure the rubber boot is present on the cylinder valve. If the boot is missing, remove from service. (4) For a remote connect cylinder, ensure the dove tail feature is not damaged or cracked. If damaged, remove from service Carrier Assembly (1) Operate the latch on the cylinder band to ensure that it opens and closes properly and that it holds the cylinder securely. (2) Ensure that the lumbar pad is attached securely. (3) Ensure the power module and pressure reducer are secured to the back plate by the lower cover. (4) For remote connect cylinders, ensure the dove tail feature on the lower cover is not damaged or broken Page 4 of 7 1055.09.04 Functional Tests 1) 2) 3) 4) Check that the Regulator and Face piece Can Hold a Negative Pressure Close the cylinder valve and purge any air from the system using the bypass knob Hold the face piece against the face to create an effective seal. Attach regulator to the face piece and inhale until the face piece begins to collapse against the face. 5) Hold breath for approximately 10 seconds. a) Negative pressure should be maintained and the face piece should remain collapsed against the face for the entire 10 seconds. 6) Do not use the SCBA if negative pressure cannot be maintained in the face piece. 7) Check Function of Regulator 8) (Push the release buttons on the side of the regulator to ensure the regulator is shut off. 9) If the regulator is equipped with a bypass valve, ensure that the bypass knob is fully closed (clockwise). 10) Open the cylinder valve and ensure the valve is completely open. 11) Observe the LED display. a) The LEDs must illuminate in a sequenced pattern. 12) After the sequence is completed, the corresponding system pressure will be displayed. 13) Open the bypass knob (counterclockwise). a) Ensure that air flows from the regulator. 14) Close the bypass knob (clockwise). 15) Attach the regulator to the face piece. 16) Ensure proper attachment by pulling on the regulator. 17) Don the face piece or hold the face piece against the face to create an effective seal. 18) Inhale sharply to start air flow. 19) Breathe normally. 20) Ensure proper regulator response. 21) The regulator should NOT make any unusual sounds including whistling, chattering, or popping 22) Remove the face piece from the face. 23) Ensure that air flows freely. 24) Push the regulator release buttons. 25) Ensure that air flow stops. Page 5 of 7 1055.09.05 Control Module (1) When testing the control module, lay the control module down flat to check the white light illuminating the pressure gauge and to check if the graphical display and the analog gauge are consistent within a 5% range (225/4500 psi) with the cylinder pressure. (2) Both reset buttons on the control module have the same function. Use one when resetting the motion alarm and the other when testing the manual alarm. (3) Verify proper function of the HUD, control module, power module, and low pressure warning device by observing the control module gauge and display when the alarms sound. Perform this test with a full cylinder.
