This mornings class is back at it with working in no visibility and having to make a UAC connection by relying on feeling the connection to both the downed firefighter and themselves. A UAC (universal air connection) is used to supply a firefighter with air from another firefighters pack. This connection takes the fullest bottle and equalizes both air bottles so they have the same amount of air to get to a place of refuge or escape the building.
