摘要
A self-contained breathing apparatus (SCBA) comprising: a mouthpiece; a breathing component; and a safety quick disconnect comprising: a valve body; a valve spool comprising an L-shaped channel formed such that when the valve spool is appropriately rotated, the L-shaped channel (i) places an opening of the valve body in communication with a first port, or (ii) places the opening in communication with a second port; and a lock mechanism for (i) preventing the valve spool from rotating unless the breathing component is positioned in one of first and second mounts formed on the valve body adjacent the first and second ports, and a replacement breathing component is positioned in the other of the first and second mounts, and (ii) preventing the removal of a breathing component from a mount adjacent to a port which is in communication with the opening.
