Buddy Breather
Two SCBAs equipped with a G1 Buddy Breather System can share a common air supply during
emergency escape. The Buddy Breather System is an Emergency Breathing Support System
(EBSS).
NOTE:
Activating the Buddy Breather 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 medium pressure air from the donor's pressure reducer and cylinder. The
duration of the remaining air supply will be reduced to approx. 50%.
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 to approx.
50%. 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. 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 breathing apparatus 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 medium 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 if present. Use of Quick-Fill maintains approval while transfilling and does not exhibit
the above hazards.
17.1 Use
The G1 Buddy Breather System contains two quick-connection fittings, capable of connecting with
both male and female fittings on another user's manifold.
(1) Quick-connect fittings require a single action to connect: Push the coupler firmly over the
plug to engage.
(2) Quick-connect fittings require two actions to disconnect:
a) Push the two sides of the quick-connect towards each other. The plug should advance into
the coupler end.
b) Slide the coupler's outer sleeve away from the plug. Pull the plug out of the coupler.
Ensure that the Quick-connect plug on the manifold black is protected by the supplied dust
cap.
WARNING!
DO NOT install or attempt to use any hose assembly or fitting other than those supplied by MSA
for the G1 Buddy Breather System. Misuse can result in serious injury or death.
17.2 Inspection Before Use
Emergency Breathing Hose
(1) Inspect the elbow connection to the G1 First Stage Regulator as well as the hose connection
to the elbow.
a) Ensure the hose is properly secured.
(2) Inspect the dust cover.
a) Ensure that the cover is securely attached to the male and female quick-connect fittings.
(3) Ensure the emergency breathing hose is coiled in the pouch such that it is not twisted.
