Info:

 

 The Navy in cooperation with the Mining Safety Equipment Company (MSA), developed a portable oxygen generating & rebreathing apparatus that would provide and sustain oxygen provision for dirigible aircrews if required for higher altitude flight. This system, which was constructed of aluminum and painted "oxygen green",  used a chemical oxygen generation process that would provide an aircrewman with aviation grade oxygen for a specific period of time, when used in cooperation with a demand type valve. The standard US Navy system incorporated the Navy's "C" oronasal breathing mask that could be secured to the head with a strap suspension. An earlier version of this chemical oxygen generation set also used a mouthpiece very much like that used in diving sets (that is, fitted with a flange that was positioned behind the lips and in front of the teeth, so as to assure retention).   This individual chemical oxygen generation assembly could also be used in larger aircraft, but it is doubtful that this was a common practice, owing to the weight factor. By the early 1940s this system was also in standard use on US Navy non-rigid 'blimps'.]
