G1 ExtendAire II EBSS

General Information
Two SCBAs equipped with a G1 ExtendAire II System can share a common air supply during emer-
gency escape.
NOTE: Activation of EBSS changes both the donor and receiver to Escape Only, and the user must
immediately evacuate to fresh air outside the hazard zone.
Both users will receive intermediate pressure air from the donor's pressure reducer and cylinder. The
duration of the remaining air supply will be reduced by at least half.
NOTE: The National institute for Occupational Safety and Health (NIOSH) did not approve the inter-
connection of apparatus using "Buddy Breathers" or EBSS prior to NFPA 2013-edition standard units.
Interconnection of pre-2013 edition SCBAs with an EBSS device results in a non-approved NIOSH
configuration.
WARNING!
Users must be trained in the operation of EBSS in accordance with a training program conforming to
NFPA Standards 1404 and 1500 prior to any attempt to use such equipment in an emergency situa-
tion. Misuse can result in serious injury or death.
CAUTION!
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 is 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.
WARNING!
DO NOT use the Quick-Fill System, URC assembly or G1 ExtendAire II System accessories if there
is any possibility that the environment contains a CBRN warfare agent. These SCBA accessories are
not approved for the use in atmospheres containing CBRN warfare agents. Failure to follow this
warning can result in serious personal injury or death.
