I thought it was ozone.

It is also that.

Petrichor is the smell of rain and is a term like Channelle #5 where it's a combination of ozone and geosmin and other compounds.

Ozone is the smell of an electrical fire

Or poliester fleece or blanket when you hear little sparks.
Some will remember playing with a CRT TV screen 👀

I remember the feeling and the sound, but not scent.

Smells kinda dry and vaguely fishy/metallic. It's very distinct, you know it when you smell it.

Should be noted however that it's not very healthy to breathe it in and large and/or repeated exposures can cause respiratory damage. Some static electricity is probably fine but I don't want to encourage someone to go out there and learn what it smells like first hand

Also welding. Also lasgun shots

When I first started learning how to weld, I always wore a respirator because a lot of the fumes can be dangerous. So anyway, we come back to the shop after our lunch break and my first thought was damn, what's that smell?

Diff smell.

I call this 'outside' smell and you can smell it on a clear day.

There's also fat volatiles in our skin that metals and sunlight degrade, so that outside smell could be the smell of you in the sun.

There's a saying, someone smells like sun.

I find I smell it more often this time of year. I guess the heavier and colder air?
