Abstract:
A control system, comprisinga plurality of breathing apparatii, each of said plurality of breathing apparatii having a source of gas; a face mask connected to said source of gas wherein gas is passed from said source of gas through said face mask; a first sensor mounted on said face mask wherein said first sensor detects an amount of exhaled carbon dioxide and produces a first data signal indicative thereof; a second sensor attached to said face mask wherein said second sensor detects an amount of carbon monoxide in a user's blood when wearing said face mask and produces a second data signal indicative thereof; a third sensor attached to said face mask wherein said third sensor detects an amount of oxygen in the user's blood when wearing said face mask and produces a third data signal indicative thereof; a processor connected to said first, second and third sensors wherein said processor receives the first, second and third data signals from said first, second and third sensors, respectively, and creates at least one condition signal indicating a hazard condition wherein the condition signal is derived from the first, second and third data signals; a display attached to said face mask and receiving said condition signal wherein said display indicates to the user whether a hazard condition exists; a transmitter/receiver unit connected to said processor wherein said transmitter/receiver unit receives data from said processor and transmits said data to a base unit; and a plurality of base units, each of said plurality of base units: having a base processor and a storage unit for processing and storing data from a plurality of transmitter/receiver units; transmitting data to each of said transmitter/receiver units; and monitoring the status of said sensors in said breathing apparatus.
