Unusual question, I know - and the answer includes “you don’t want to know” and “why in the world do you think you could be smelling fluorine?”
But I have my reasons.
I’m going to try to describe the smells of the halogens I know. I think there is a common sharp, piercing scent or sensation that is common to all of them. I think chlorine smells a bit rotten and ugly. I think bromine smells a bit more woody or nutty. I think iodine smells a bit more earthy like early Spring thaw.
So, I smelled something in a situation where there could have been free fluorine or HF, and it had the piercing commonality I recognize in the bigger quieter halogens, and it additionally had a sort of floral or ethereal note. In this situation I don’t think there was any reason to smell anything besides fluorine compounds. I noted that I did NOT suffer any ill effects. There was a bit of a safety issue there that is getting dealt with.
What say the dopers? Could this possibly have been fluorine?
