Is there such a thing as antiseptic gas?

Is there such a thing as antiseptic gas?I was in a Fry's grocery store the other day, and smelled something like a cross between cinnamon and root beer by the registers. There are a number of hand soaps (so maybe sanitzers) that have a spicy smell like this. We brought a bunch of scented
There is a used bookstore near me that runs their ozone generator on their air handler year around now, not just during winter, with COVID-19. Might be a whopping 0.05 to 0.07 ppm in places.That's fairly high ozone levels. You would think folks would find that annoying. Ozone is not a pleasant odor.

You would think folks would find that annoying.Ozone-in-air is nasty (makes a little NOx too). Ozone-in-oxygen is a little "sweeter". And either can trigger an asthma attack, headaches, and anemia.

I took a shot of 12wt% ozone into my nose once, the shock made me whiff it in. Was wiped out for hours. Low gas flow, never sure if it is making ozone or not...

I am well acquainted with ozone in my workplace.
We use UV lamps to cure coatings and inks. The
lamps are very good at generating ozone as a
byproduct. Every now and then, the exhaust
ducting would fail and operators would begin to
complain about headaches, eye irritation and
itchiness.
One trip to the affected area tells me immediately
what the problem is. We've measured levels from
0.08 (max recommended over 8 hours) to 1.5 ppm (nasty).
Shutting down the lamps and getting maintenance
to fix the exhaust is an easy solution.
Dear Dean:Hi David, yes it is nice to have actual chemistry in here! We had air sampling done and results showed no NOx. We did see a few ppm of N-vinyl pyrrolidinone which is a component in one of the coatings we use. That prompted us to add extra ventilation

Not trying to claim you did not know what you were talking about. Just nice to discuss actual "chemistry" here for a change.
