aka RIC (rapid intervention connection)
Used when you or your partner in an IDLH is or has run out of air.
a high pressure hose is carried in a pouch on the SCBA pack. this hose has 2 female ends that connects one female end to a male end in the lower back of the pack, the other end to a second pack, when connected the hose will equalize the pressure between both packs. Will equalize pressure in 27 sec. |
