OOS- allows damage to UAC or debris to enter
PRA reduces operating pressure to _
Malfunction of PRA primary system will automatically direct breathing air into a secondary system causing _
100 psi before entering regulator’s low pressure hose
Operating pressure to reduce to 150 psi & cause vibralert alarm to activate. Member must leave IDLH
Failure of Primary & Secondary system in open position will activate Relief Valve in PRA. This will _
Rapidly discharge all pressure in excess of 185 psi into the atmosphere. Partially close cylinder to minimize air release. Leave IDLH
The pressure inside a donned facepiece is (higher/lower) than pressure outside
If after donning the facepiece, the manual shut off fails to release- what is done
Positive pressure is higher than atmosphere pressure to prevent contaminants from entering
Turn red purge valve downward 180 degrees to start flow of air & notify Off & leave to safe area
What is done for failure of regulator in the open position (too much air flow in facepiece)
Do the vibralert & HUD work dependently or independently w/each other
Air flow can be controlled by opening the purge valve fully & partially closing the cylinder valve. Leave IDLH
Independently- may not activate at precisely the same time

1/2 cylinder (yellow) 1 flash per second; At 1/4 Red light flashes 10X a second
Bottom 1st & then top (bottom’s up)
A round light indicator on far right of display lights for 20 seconds & then begins to flash slowly once a second. What does this indicate?
Low battery- still have sufficient life to operate HUD longer than longest duration of SCBA cylinder, however, batteries must be changed immediately upon termination of use of SCBA or before re-entry into Hazardous atmosphere
Motion sensor module does not sense motion of SCBA for _ pre-alarm
If SCBA full alarm is heard for _ seconds- notify IC
20 seconds pre-alarm; 12 more seconds after that full alarm

10’
Is activation of Vibralert alarm an indicator that valve is fully open
What happens if FF becomes entangled or trapped
No- turn counterclockwise until fully opened to stop position
Transmit Mayday & then attempt to free self. Cancel Mayday after freed

B. When the PRA’s primary and secondary system fail the cylinder valve should be partially closed.
C. When the regulator fails in the closed position partially close the cylinder valve.
D. When the regulator fails in the open position the condition is handled by using the manual shut off and the purge valve.
B
A. If the leak is more than can be controlled with one hand:
1. Continue to cover as much of the damaged area as possible.
2. Press the manual shut-off switch after each breath to further limit the loss of breathing air.
3. If damaged area is too large to allow the regulator shut-off to release, then use the purge valve in an ON & OFF motion for each breath. This helps conserve the limited amount of breathing air necessary for escape.

Scott 4.5 NIOSH Rated Service Time Cylinders with their SCBAs- service duration times for 30, 45 and 60 minute cylinders are determined by a NIOSH Breathing Machine. Tests simulating an avg adult moderate work rate of 40 liters per minute is used to differentiate approximate liters per cylinder size. Which choice below is incorrect?
A: All 4.5 cylinders are pressurized to 4500psi
B: 30 minute cylinder = approximately 1200 liters
C: 45 minute cylinder = approximately 2000 liters
D: 60 minute cylinder = approximately 2400 liters
C) 45 minute cylinder = approximately 1800 liters
A good way to determine the number of liters in each cylinder is to multiply cylinder size by “40”
Example: 30x40=1200; 45x40=1800; 60x40=2400
TB SCBA 3.2.6, 3.2.7

D. Kept in their sealed pouches in the infection control compartment on the rig
D
Cleaning & disinfecting Unit’s SCBA regulators: incorrect
A. Regulator is to be cleaned & disinfected utilizing 70% isopropyl alcohol in a spray bottle, & drinking water (running or in a spray bottle)
B. Spray a minimum of 6 full pumps of Isopropyl Alcohol into the regulator opening. Allow for 10 min of contact time prior to rinsing with water
C. Shake excess water out of regulator, then air dry regulator prior to use. To expedite removal of water the regulator should be banged or tapped gently against a hard surface
D. Perform a regulator check by opening the purge valve & observing air flow from the regulator spray bar. Water droplets indicate the regulator is not dry
C Do NOT bang/tap regulator

C Will operate for approximately 1 hour
Incorrect for regulator
A. For a regulator failure in the closed position, turn the purge valve counter clockwise
B. When the regulator fails in the open position, air flow can be controlled by closing both the purge valve & cylinder valve
C. Manual Shutoff valve must be pressed prior to removing the facepiece. If not a full 45 min cylinder can be depleted in approx 4 minutes
D. When pressed, the switch on the manual shutoff holds the regulator in the closed position, stopping the air flow. The switch automatically releases when the member inhales through the facepiece, starting the airflow
B Regulator in Open position: open purge valve fully and partially close the cylinder valve
3.8.4
Incorrect for Damaged facepiece
A. Leave the facepiece on & cover damaged area with one hand
B. If leak is large, press the manual shutoff switch on the regulator after each breath to limit the loss of breathable air
C. If damaged area is too large to allow regulator shut off, leave the purge valve in the open position to continually supply air to the member
D. Immediately leave contaminated area accompanied by another member
C Use Purge valve On and Off motion for each breath. This action helps to conserve the limited amount of breathing air necessary for escape
