ABSTRACT:
A method of verifying and indicating proper or improper functioning of breathing apparatus for an irrespirable environment. The breathing apparatus includes gas supply for supplying a user with breathable gas, at least one electrical component, a processor connected to the at least one electrical component, and at least one status indicator connected to the processor. A test signal is generated with the processor. The test signal is sent to the at least one electronic component of the breathing apparatus. A response to the test signal is generated with the at least one electrical component of the breathing apparatus. The response is transmitted to the processor. The response is compared to a predetermined response corresponding to proper functioning of the at least one electronic component of the breathing apparatus with the processor to determine a status of the at least one electrical component of the breathing apparatus. An output signal is generated with the processor corresponding to the proper or improper functioning of the at least one electrical component of the breathing apparatus. The output signal is transmitted to the status indicator. A status signal is generated with the status indicator to indicate the proper or improper functioning of the at least one electrical component of the breathing apparatus.
