A control interface operationally connects the self-contained breathing apparatus to the powered air-purifying respirator. The self-contained breathing apparatus includes a pressure vessel, a cylinder valve assembly and a pressure reducer, all carried by a back frame, and the powered air-purifying respirator is adapted to be mounted on, and carried by the back frame, by coupling the back frame and the respirator together at respective attachment points.
