From what I read, it is hydogen sulfide, (Rotten egg gas) metabolized by cyanobacteria to sulphuric acid. The pools have extremophiles that like 120 degrees C.

pH 3.5 is acidic but not very much. And skin should be able to withstand lower pH values (stomach acid).
It must have been the heat that did it for him in the first place.
The skin that was in contact with the puke was burned and peeled off.
The digestive system has lots of protective substances which allow it to be able to handle that acid.

Originally posted by AThousandYoungWhen I first got in the USAF, I had a buddy who had a bit of a drinking problem, we were in barracks maybe 50 to a building and all we had to sleep on were these skinny beds which has a mattress that has a full cover like a huge pillow case. So in comes Sam after a night of boozing, crawls into his bunk and didn't know he had inadvertenly crawled under the mattress cover and was a bit trapped there like being inside a sleeping bag with out the zipper, locked in place.

Well naturally he pukes inside the cover and passed out. Then in the morning we hear this gagging sound, moaning as such, I'm stuck in here, help🙂 So we had to help him out of that bag and he got immediately into the shower to clean up and the mattress and cover was thrown out and he had to get a new on rec'd to him. He was only slighty embarrassed🙂

There's a movie 'gone into the wild' about an American guy who went to live on the land, ended up eating poisonous plants and dying a slow death, was based on a true story. Sometimes, myself included, people think they can do things they really shouldn't. I broke a small bone in my foot and got completely lost going off trail in Ecuador, $hit happens to the adventurers.

I shudder to think of ever getting in that situation.
One time back when I was in the USAF a LONG time ago, in Lincoln Nebraska (there was an AF base there at one time) anyway, I was driving my old tank, something like a 1948 buick or some such and was driving around this farmers field and I found this watering lake, maybe 300 feet across or so and I started driving down to it, only to find out it was very muddy and my car was slipping downhill into the water....
So I pulled out my physics and knew if I could go in a more or less straight line centrifugal force would get me back uphill out of the mud and that is what happened, I think I circled the dam thing 3 times before I could get enough velocity up to get uphill far enough to get out of the slippery mud🙂 Kind of like escaping from a planet in a space ship. I learned never to pull THAT stunt again🙂
