Training is required in order to provide or receive emergency breathing
support using the ExtendAire II Intermediate Pressure
Accessory Kit.
1.
To deploy the emergency breathing hose, open the snaps and
hook and loop on the flap of the waist mounted pouch.
2.
Locate the manifold end of the emergency breathing hose and
remove it from the pouch.
3.
Remove the dust cover from quick-connect fittings on the
manifold.
4.
The quick-connect fittings require a single action to connect.
Firmly press the female quick-connect fitting on to the male
quick-connect fitting until they are engaged.
5.
Connect one of the quick-connect fittings on the emergency
breathing hose to the second air mask in the following scenarios*:
a.
If the second air mask also has
the ExtendAire II Intermediate
Pressure Accessory Kit:The
emergency breathing hoses
can be connected together.
The manifold contains a
male and female quick-
connect fitting. Either fitting
can be used to connect to a
manifold of a second air
mask.
b. If the second air mask does
not have the ExtendAire II
Intermediate Pressure
Accessory Kit, but does have
the ExtendAire Intermediate
Pressure Accessory Kit
installed in line with the
Firehawk® Second Stage
Regulator hose: The female
quick-connect fitting of the
emergency breathing hose
can be connected to the male quick-connect fitting on the in-
line manifold of the Firehawk Second Stage Regulator hose.
c. If the second air mask does
not have the ExtendAire II
Intermediate Pressure
Accessory Kit and does not
have the ExtendAire
Intermediate Pressure
Accessory Kit, but does have a
Firehawk Second Stage
Regulator with a quick-
connect fitting:The user of
the second air mask must
hold their breath and disconnect the quick-connect fittings on
the regulator hose and then connect the female quick-connect
fitting of the regulator hose to the male quick-connect fitting
located on the emergency breathing hose of the first air mask.
Perform the disconnect and connect steps quickly. The receiver will
not have a supply of breathable air while the receiver’s second stage
regulator hose is disconnected. Failure to follow this warning can
result in serious personal injury or death.
6.
Emergency breathing will begin immediately when the quick-
connect fittings are engaged.
7.
Immediately escape to fresh air before disconnecting.
DO NOT disconnect until both users reach fresh air. One cylinder
(donor or receiver) may be consumed entirely before the other,
resulting in no air supply for one user. Failure to follow this warning
can result in serious personal injury or death.
8.
To disconnect the quick-connect fittings:
a. Push the two quick-connect fittings toward each other.
NOTE:
The male quick-connect fitting should advance in the
female coupler approximately 1/8”.
b. Slide the outer sleeve on the female quick-connect fitting
away from the male quick-connect fitting, pulling the fittings
apart.
9.
