ABSTRACT:
The present invention provides a self-contained breathing apparatus ("SCBA") having a personal alert safety system ("PASS") fully integrated therewith. The PASS is structurally integrated with the SCBA such that it is protected from damage by both the air cylinder and the frame. The integrated PASS device is not only automatically activated when the SCBA is being used but can still be activated manually if the SCBA is not in service. Additionally, the integrated PASS device utilizes a unique electrical/mechanical connection assembly between its various parts which greatly increases its ruggedness and durability.
