20 Questions
What is the correct sequence of actions to perform when checking the function of the regulator?
Shut off the regulator, then open the cylinder valve, then open the bypass knob
What should happen when the power module sounds during the test?
The primary low pressure warning alarm sounds briefly
What is the purpose of pressing the release buttons on the side of the regulator?
To shut off the regulator
What should happen to the buddy lights during the test?
They flash green and then red
What is the consequence of not being able to maintain a negative pressure in the facepiece?
The SCBA should not be used
What is the primary purpose of holding the facepiece against the face during functional testing?
To create an effective seal and verify negative pressure
What is the acceptable range of pressure gauge readings on the control module during testing?
Within a 5% range of the cylinder pressure
What is the function of the reset buttons on the control module?
One resets the motion alarm, and the other resets the manual alarm
What is the correct step to perform before conducting functional tests on the SCBA?
Check the pressure gauge on the cylinder valve to verify that the cylinder is full
What is the purpose of the bypass knob or purge cover on the regulator during functional testing?
To purge any air from the system before testing
What should you do to the control module to reset the PASS alarm?
Press the reset button on the left side of the control module twice within approximately one second
What should you inspect on the second stage regulator hose before using it?
The entire hose for bulging, deterioration, dirty O-rings or seals, cracks, debris, tears, holes, stickiness, signs of heat or chemical-related damage, or other visible signs of damage
What should you do to the facepiece after attaching the regulator?
Don the facepiece or hold the facepiece against the face to create an effective seal
What should you check for after inhaling sharply to start air flow?
All of the above
What should you do to the bypass knob after the full alarm sounds?
Close the bypass knob (clockwise)
What is the minimum pressure at which the primary low pressure warning device should alarm?
200 psi
How do you reset the PASS alarm?
Press the reset button twice within approximately one second
What should happen to the buddy lights during the test?
They should flash red
How do you ensure a proper seal on the facepiece?
By attaching the regulator and inhaling sharply
What should you do when the system pressure falls below 200 psi?
Turn the control module off (sleep mode)
Verify the proper functioning of SCBA components, including the HUD, control module, power module, and low pressure warning device. Ensure negative pressure can be maintained in the facepiece and check the regulator's shut-off and bypass valve functions.
