Patent ID: 8430096

Claim:
A self-rescuer comprising: a self-contained breathing apparatus (SCBA); and a smart light; wherein the smart light comprises: a battery; a light bulb; circuitry connecting the battery to the light bulb; a detector for detecting the presence of a hazardous atmospheric condition; and alert apparatus connected to the detector for alerting a user when a hazardous atmospheric condition is detected by the detector, and further wherein the alert apparatus is connected to the circuitry and configured so as to flash the light bulb when a hazardous atmospheric condition is detected; wherein the self-contained breathing apparatus (SCBA) comprises: a mouthpiece; a breathing component for providing breathable air, the breathing component comprising a component interface; and a safety quick disconnect comprising: a valve body defining: an internal chamber; an opening communicating with the internal chamber and connectable with the mouthpiece; first and second ports communicating with the internal chamber; first and second mounts formed on the body adjacent to the first and second ports, respectively, for receiving the component interface of the breathing component, the first and second mounts being configured so as to place the breathing component into communication with the internal chamber when the component interface is in engagement with one or the other of the first and second mounts; a valve spool selectively rotatably disposed within the internal chamber, wherein the valve spool comprises an L-shaped channel formed such that when the valve spool is appropriately rotated, the L-shaped channel (i) places the opening in communication with the first port, or (ii) places the opening in communication with the second port; and a lock mechanism for (i) preventing the valve spool from being rotated unless the component interface of the breathing component is positioned in one of the first and second mounts and a component interface of a replacement breathing component is positioned in the other of the first and second mounts, and (ii) preventing the removal of a component interface from a mount adjacent to a port which is in communication with the opening.
