SCBA-Chp 6 Air Emeergencies, RIT Pak, and SCBA Failures page 1
Airway - check facepiece lens, gasket, and interface with the breathing regulator is intact. replace if needed
Breathing- breathing regulator intact and attached to facepiece by visual inspection. replace if needed
Cylinder- look at remote gauge, cylinder gauage, or heads up display. If less than 1800 psi use RIT PAK or SCBA to supplement
Straps- Shoulder straps should be tightened down and then secured by taking two round turns or tying an overhand knot around the strap below the adjustment buckle before extrication.

Describle what the SCBA does and what the user should do
SCBA-Chp 2-SCBA, PAK Tracker and HHR Specifications Page 54
-High pressure air enters the outlet manifold
-the over pressure relief valve will open
-only 185-225 psi will enter the low pressure hose
-vibralert will sound, along with loud escaping air
-partically close the cylinder valve to reduce the amount of air loss, rotate clockwise
122
Failure of Breathing regulator failed closed
SCBA-Chp 2-SCBA, PAK Tracker and HHR Specifications Page 55
-Fully open the purge valve counterclockwise 180 degrees
123
Breathing Regulator Failed Open
SCBA-Chp 2-SCBA, PAK Tracker and HHR Specifications Page 55

What happens when Buddy Breathing is conducted between two SCBA's
SCBA-Chp 2-SCBA, PAK Tracker and HHR Specifications Page 56
-If it's due to low air
-Both users vibralert will activate upon initial connection
-An Automatic switch in the Pressure reducer diverts use of air to the cylinder with the lowest pressure
-The lower cylinder will be depleted (less than 500psi). At 500 psi both users will breath from the 'rescue' bottle
-Once the bottle falls below 25% 1000-1200psi both vibralerts will activate
126
Using the high pressure air supply using the RIT-Pak
SCBA-Chp 2-SCBA, PAK Tracker and HHR Specifications Page 57
