Chemically, I would agree.  Which is why the OS who had it happen to him first wasn't strongly believed by myself (MS) or the PO2 who was present in the Aft ERT.  So, the PO2 supervised me, step by step, properly checking, and donning the Chemox.  We inspected the canister, installed, closed the bale, and yes, I got what smelled like Chlorine in the face.

How?  I'm not a chemist, but it happened.

More than just me as well.  There was a good lineup of us outside sickbay.

I can't tell you what you smelled, but unless the canisters had a severe manufacturing defect (e.g. filled with a completely wrong substance), what you smelled was not chlorine.  It is in no way possible to extract chlorine gas from potassium superoxide.
Sure, apes read Nietzsche.  They just don't understand it.

I agree - but Chlorine is what I smelled.

Same with the OS.

Along with the PO2 who supervised me.

Along with others on the ship who encountered canisters from the same batch.

Contaminated canister?  Manufacturing defect?  Don't know. 

I do know what Chlorine smells like though.

Just because something smells like something, doesn't mean it is that thing.  Sarin smells like "new-mown hay," but it most definitely is not!

If there were a number of canisters at once, was probably from the same batch with some kind of contamination during the manufacturing process.   There may have been some impurities or something that released a bit of chlorine (maybe simple table salt ionizing and off gassing?); unfortunately it can happen by something as simple as not cleaning out the equipment properly in the manufacturing line.

Once made straight chlorine gas by accident in a lab by not following instructions closely enough and caught enough of a whiff for it to hurt (that was with a fume hood).  On the plus side, you can smell chlorine at doses far lower than what is harmful, but if you had gotten a lungful at a high enough concentration, you would have been foxed, so it's unlikely it would have been the wrong chemical all together (that would have just killed you).
