General Knowledge

Universal Air Connection (UAC)

A

3.5.1
SCOTT 4.5 SCBAs are fitted with a UAC System which permits emergency replenishment of an approved SCBA breathing air supply cylinder on a user’s SCBA from an approved air supply source while in use. This is not a Quick Charge attachment and must not be used for routine recharging of the air cylinder, buddy breathing, transferring air from another SCBA, or any other unapproved use. The UAC is for emergency use only when the SCBA user is incapacitated within the hazardous atmosphere. The UAC manifold is equipped with a relief valve which will open if the supply pressure of the emergency air supply exceeds the maximum pressure rating of the complete SCBA. However,
the supply pressure from the High Pressure Coupling, of the emergency air supply to be connected to the UAC, must not exceed 4500psi.
