EXTENDAIRE SYSTEM
PROVIDING OR OBTAINING EMERGENCY BREATHING
S
UPPORT
Follow these procedures to connect and disconnect
the emergency escape breathing system hardware.
Individual development of operating procedures and
s
ufficient training is required to use this equipment in
actual emergency conditions. Failure to follow this
warning can result in serious personal injury or death.
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.
3. Connect the receiver's second stage regulator hose to
the donor's manifold block.
a. Push the socket 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-
g
led 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
l
east) be reduced in half.
4. 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.
5. Replace the dust cap on the Snap-Tite plug.
The receiver's facepiece or regulator must be
removed upon disconnection from the donor's air sup-
ply. Failure to follow this warning can result in serious
personal injury or death from suffocation.
