ABSTRACT:
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.
