The Hip-Pac with Miller Class 3 Fall Protection Harness combines respiratory protection and Class 3 fall protection into one device. The Hip-Pac offers the same reliable facepieces and second stage regulators as the Cougar and 1997-style Panther SCBAs. It allows the user to comfortably wear the respirator to enter an IDLH environment while breathing from a remote air source. Should the air supply be interrupted, the user can switch to the cylinder for escape. The escape cylinder is available in 5, 10 and 15 minute durations.
