Smelly O2

>>> . . .whether or the oxygen smells. . .

The oxygen doesn't smell, but it is released from an "oxygen sponge" of (mostly) sodium chlorate in a chemical reaction that heats the NaCl03. The system creates a lot of heat (circa 250C) in the overhead and things often smell like burning. . . things.

Google "chemical oxygen generator."
