EXTENDAIRE SYSTEMS
PROVIDING OR OBTAINING EMERGENCY BREATHING
SUPPORT
Follow these procedures to connect and disconnect
the emergency escape breathing system hardware.
Individual development of operating procedures and
sufficient training is required to use this equipment in
actual emergency conditions. Misuse can result in
serious injury or death.
ExtendAire System Hose Connection Procedure
1. Remove the dust cap from the quick-disconnect on
the donor's intermediate pressure manifold block.
2. Disconnect the receiver's second stage regulator hose
from their intermediate pressure manifold block by
disengaging the Snap-Tite quick-disconnect fitting.
Perform the following disconnect and connect steps
quickly. The receiver will not have a supply of breath-
able air while the receiver’s second stage regulator
hose is disconnected. Misuse can result in serious
injury or death.
3. Connect the receiver's second stage regulator hose to
the donor's manifold block.
a. Push the coupler of the receiver's hose firmly over
the plug on the donor's manifold.
b. Check that the hose is properly routed and not tan-
gled with any other part of the apparatus (i.e. neck
strap, chest strap, etc.)
c. Check for full engagement by pulling at the quick-
disconnect to assure that the socket does not sepa-
rate from the plug. The apparatus of the donor will
supply air for emergency escape of the two individ-
uals. The duration of the remaining air supply will (at
least) be reduced in half.
ExtendAire System Hose Disconnection Procedure
1. Upon reaching a safe, non-toxic atmosphere, a stag-
ing area or performing other emergency egress proce-
dures, uncouple the receiver's hose at the quick-dis-
connect.
2. Replace the dust cap on the Snap-Tite plug.
ExtendAire II System Connection Procedure
1. Pull on the pouch opening of both the donor's and
receiver's pouches.
2. Fully remove the manifold and hose from each pouch.
3. Remove the dust caps from both manifolds.
4. Connect the receiver's manifold to the donor's mani-
fold.
a. Push the coupler on the receiver's manifold firmly over
the plug on the donor's manifold.
b. Check that the hoses are properly routed, not kinked,
and not tangled with any other part of the apparatus
(i.e. second stage regulator hose, neck strap, chest
strap, etc.)
c. Check for full engagement by pulling at the quick-dis-
connect and assure that the coupler does not sepa-
rate from the plug. The apparatus of the donor will
supply air for emergency escape of the two individu-
als. The duration of the remaining air supply will (at
least) be reduced in half.
ExtendAire II System Disconnection Procedure
1. Upon reaching a safe, non-toxic atmosphere, a stag-
ing area or performing emergency egress procedures,
uncouple the receiver's manifold at the quick-discon-
nect.
2. Replace the dust caps on the quick-disconnects.
3. Coil the hose neatly, insert into the pouch, and close
the pouch by fastening the snaps.
The receiver's facepiece or regulator must be
removed upon disconnection from the donor's air sup-
ply. Misuse can result in serious injury or death from
suffocation.
EXTENDAIRE AIRLINE ATTACHMENT OPTION
INSTRUCTIONS FOR USE GENERAL INFORMATION
With the use of the ExtendAire Adaptor Hose Kit the air
mask becomes a combination type apparatus. It is first a
self-contained breathing apparatus for either 30, 45 or 60
minute service. Second, it is a supplied-air respirator
which requires a supply of air from either a stationary
cylinder or a compressor.
This apparatus is approved by the National Institute for
Occupational Safety and Health (NIOSH). It is approved for
use as a 30, 45 or 60 minute pressure demand self-con-
tained breathing apparatus for entry into and escape from
oxygen deficient atmospheres, gases, and vapors. It is
also approved for use as a combination apparatus for res-
piratory protection during entry into and escape from oxy-
gen deficient atmospheres, gases and vapors when not
more than 20 percent of the rated capacity of the cylinder
is used during entry. When used as a combination appara-
tus, the device shall be supplied with respirable air through
8 to 300 feet of MSA air supply hose within the pressure
range of 85-90 psig.
GENERAL INFORMATION
An air mask which has been converted with an
Intermediate Pressure Accessory Kit includes a new inter-
mediate pressure hose assembly. In the middle of the
hose is an aluminum manifold tee with a black Snap-Tite
quick-disconnect plug. An airline hose can be connected
to this plug by using an adapter hose assembly.
