ExtendAire II Operation
G1 Industrial SCBA
US
13 ExtendAire II Operation
The ExtendAire II system allows two users to connect and share intermediate pressure air. The
ExtendAire II includes a manifold, hose assembly, and pouch. The manifold includes both male and
female quick connects to enable connection to a second ExtendAire II.
WARNING!
The SCBA is approved by NIOSH without inter-connecting two users to one apparatus. NIOSH does
not certify "buddy breathers". Therefore, the attachment of the receiver's ExtendAire II to the donor's
ExtendAire II voids NIOSH approval for both respirators.
WARNING!
Use this emergency escape breathing system for life threatening emergencies and simulated training
exercises only. All other adequate means of escape must be considered before using this device.
During use, the air supply and consequentially the remaining service time is reduced approxi-
mately in half. Before connecting two users make sure the air supply is sufficient for both users to
escape; otherwise do not use the system.
DO NOT use the system if the donor's low pressure warning device is alarming (ringing). Using the
system at this time can result in both users running out of air during escape.
Exercise extreme care while connected together. Mobility and range of motion will be limited when
donor's and receiver's air masks are connected.
Maintain slack in the air lines during maneuvering and while connected together. DO NOT pull on
the hoses. Pulling on the rescue hose to the intermediate pressure hose could separate the hoses
from fittings and result in air leaks.
If the above measures cannot be followed or, to provide greater escape protection, use the
Quick-Fill System. Use of Quick-Fill maintains approval while transfilling and does not exhibit the
above hazards.
Failure to follow this warning can result in serious personal injury or death.
