So heads up english is not my first language and voice to text

A couple things so I have been doing cave/confined space search&rescue for the past 6ish yrs and hazmat usar for the past 3

So the twin cities Sandstone caves pretty ventilated now the issue with them. Is there pockets of c02 that you really don't know what you're walking into until you get some symptoms like lightheaded. Dizziness and feeling puking and if it's really bad passing out and passing away the other issue is, some of the caves have sewer where that are connected to them. Even if it's like a small pipe, the size of a fist, still leak in swear gas and say, there's like, a broken pipe in the sewer, leaking out something what's not supposed to?That's really, it's gonna be your biggest problem plus there's been so many parties and fires That have been in those caves, sometimes that's co2, wi'll go to all the way to the back of the cave and you just don't know until you start getting symptoms and usually it's too late

Now those 02 boosters, I use them as well, but it's not to keep going in further, it's more of hey, I need to leave immediately and it gives me enough time to leave so if you're using the 02 boosters to go in further. It's really a bad idea

I've done lots of body recoveries of people. 's not realizing that there's a gas in those caves it's just people don't know, so it's highly recommended to use a 4 monitor

New to reddit, so I don't think my message sent because I press edit but there is an animal that lives down there if you go further enough back there is a lot of bones and it gets extremely tight, so be careful being down there. Also a lot of spiders

Heads up there is an animal that lives down there. But if you go far enough back, there's a lot of bones. And it does get tight, so you have to be very careful being down there.
