A mask and regulator for a self-contained breathing apparatus (SCBA) having a lens and a nozzle, the regulator being adapted for connection to the nozzle. A bifurcated display is mounted on the regulator for displaying amounts of pressure through a port communicating with the lens on either side of the nozzle. A high pressure connection to the source of breathing gas is connected to a transducer assembly for indicating the pressure to the bifurcated display on the regulator on either side. The display provides pressure values through the exterior of the lens in a bifurcated manner analogous to an arcuate gauge display.

Logical display for a breathing apparatus mask

A self-contained breathing apparatus (SCBA) with a personal alert safety system (PASS) having a tank of breathing gas serving a first stage regulator connected to a mask having a demand regulator. A PASS is provided with a first audio alarm within the PASS and a circuit in the PASS which senses movement of a user of the SCBA. The PASS sounds an audio alarm after a pre-established time of non-movement of a user. A remote personal safety system (R-PASS) is attached to a location remote from the PASS, and a communication link connects the PASS to the R-PASS for sounding the audio alarm at the remote location.
