Oh man thats rough, I'm sorry you had to go through that. Speaking of smells you can't forget though, I have my own experience. Sorta, for me it was also a taste.

When I was in highschool a buddy of mine and I broke into an abandoned pool house. It was winter and about 3 am, there was a deep fog thick enough that we couldn't see eachother 10 feet apart. The pool house was surrounded by a chain link fence that had an opaque blue fabric over it so you couldn't see inside and the gate was locked with a thick padlock. We came back with bolt cutters and cut our way in instead of jumping the fence because I guess we thought it'd be cooler? Idk. Anyway we got inside through a small slat window only about a foot in height and about 10 ft off the ground. We dicked around, exploded a toilet, broke a mirror, you know how it be. Anyway eventually we found a fire extinguisher and at this point I should make it clear that this was a poolhouse that closed down in my early childhood. It'd been shut for a long ass time. So this fire extinguisher was atleast ten years expired. So obviously we used the fire extinguisher. The powder that came out was yellow and filled the room. It smelt of sulphur, chlorine, and rot. It tasted like burnt rubber. I fled the room as quickly as a possibly could coughing and retching but I could not get that taste out of my mouth nor the smell out of my noise. It made my head hurt just from the sensory overload. It took about a week for me to stop smelling it.

Anyway we also put this lifeguard chair in a tree. The camera doesn't fully capture the fog though
