Emergency Breathing Safety System (Ebss) - Honeywell Titan SCBA Training Manual

14. EMERGENCY BREATHING SAFETY SYSTEM (EBSS)

The Emergency Breathing Safety System is designed to allow connection to a supplied air line or an-
other EBSS. It is intended to supply "EMERGENCY AIR" to a firefighter who has become lost,
trapped or disoriented in an IDLH environment. The EBSS is located in a storage pouch on the wear-
ers left hip and consists of a 39 inch intermediate pressure hose and a "Y" block with a male and fe-
male quick connect.
When two SCBA's are connected using the Emergency Breathing Safety System, there is no transfer
of air. The SCBA with the higher intermediate pressure will automatically supply both SCBA's. The
users will have no way of knowing which air cylinder will be supplying the air unless they are moni-
toring their air cylinder pressure gauges. The acceptable range for setting intermediate pressure is be-
tween 80 and 150 psi. This pressure range is more than capable of maintaining positive pressure to the
facepieces of both firefighters.
