LOW PRESSURE AIR SUPPLY USE CONTINUED...
USE OF THE EMERGENCY BREATHING REGULATOR
Depending on the circumstances of the rescue, it may be necessary either to provide
air to the respirator user with the Emergency breathing regulator on the respirator user's
SCOTT facepiece, or to provide air to the user with the optional Emergency facepiece and
Emergency breathing regulator together. Refer to the following guidelines:
1.
User of the Emergency breathing regulator is indicated when:
a)
The respirator user is using a compatible SCOTT respirator with a full
facepiece but the respirator does not have any quick disconnects suit-
able for attachment of the RIT-PAK III portable air supply LOW or HIGH
pressure air supply hoses.
b)
The respirator user is using a compatible SCOTT respirator with a full
facepiece but the facepiece mounted regulator is clearly damaged or not
functioning.
c)
The respirator user is using a compatible SCOTT respirator with a full
facepiece and the fastest way to provide breathing air is to replace the
user's breathing regulator with the Emergency breathing regulator.
THE EMERGENCY BREATHING REGULATOR DOES NOT HAVE AN END-OF-SERVICE
TIME INDICATOR AND IS INTENDED ONLY FOR EMERGENCY USE ON EITHER THE
OPTIONAL EMERGENCY FACEPIECE OR ON COMPATIBLE SCOTT FULL FACEPIECES
AS PART OF THE RIT-PAK III PORTABLE AIR SUPPLY.
2.
Fully open the cylinder valve by rotating the knob counter clockwise (ap-
proximately two-and-one-half turns).
3.
Fully extend the LOW pressure air supply hose from the storage compartment
in the RIT-PAK III portable air supply.
4. Connect the male quick disconnect of the Emergency breathing regulator to
the female quick disconnect on the low pressure manifold. Verify that the
connection is secure by tugging on the connectors.
5. Briefly open and close the purge valve to confirm the flow of breathing air to
the regulator. If air is flowing freely from the regulator with the purge valve
closed, DEPRESS the air saver switch to stop the air flow.
6.
Remove the respirator user's breathing regulator from the facepiece by pull-
ing back on the regulator retaining latch and rotating the regulator 1/4 turn.
7. Immediately install the Emergency breathing regulator on the user's facepiece.
Align the two flats of the regulator outlet port with the corresponding flats
in the facepiece port (the red purge valve will be in the 12 o'clock position).
Insert the regulator into the facepiece port and rotate until the retaining latch
lock tab snaps into the facepiece.
8.
If the user's breathing is not strong enough to release the air saver switch
and begin demand breathing, fully open the purge valve to supply air to the
user.
9.
Secure the LOW pressure air supply hose to the respirator user's person
while transporting.
