Farting in the big bathtub

[Jax]

Inside or out, the gas will expand on ascent (the body not being a 'rigid' container). On that basis, if you feel the need to vent at depth, it's probably a wise idea - because the consequences of having that gas dramatically expand on ascent are quite explosive.

That said, with the effects of pressure/compression - you'd need to be producing a lot of exhaust gas to even feel the urge to vent at depth.

Y'know, that could be serious . . . if one needs to produce gas at 3 atm . . .

What's the hand signal for "I can't ascend, I have to fart first?"

I fart in a drysuit, so you can ask my buddy after he unzips me.

Ok, time for some "useless facts".
We have nerves all over our body, including in the ass. These nerves in your anus actually sense the difference between solid matter and gas, so as long as youve learned to distinguish the different feeling between gas and solids, you wont need to wear depends, youll know what is coming. Unless of course you have diarreah as very liquid fecies can fool us to believe its gas, when it is infact not. That move is called the warhammer [-]head[/-] and you DO NOT want to google it (or search for it on this forum)..

And are you that over the course of 100+ dives that you have never farted while diving?

FTFY!!

[1] The OP was talking about this issue occurring at depth. In my books [recreational diver] that means 100-130' where the ambient water pressure would effect the body's internal air spaces. If you mean 30' depth than we are talking about a horse of a different color. Actually I have never experienced flatus below 50'. I avoid eating certain foods for several hours before I do a dive like that to avoid any problems with digestion consequences of any sort.

[2] The idea of composition at depth is interesting. If you were able to magically maintain a depth of 130' for 6 or 8 hours after eating a big plate of beans [or whatever decomposes quickly] I can see how you are creating gas at ambient water pressure but would it be in enough volume to create a problem on ascent. Would the gas be of the same volume as if you had brought it down with you after the same period of decomposition?

[3] You have nerves in the area of the "exit portal" but you don't consciously control the opening and closing. If you feel an imminent breach of the portal you are able to force it to stay closed usually to avoid an embarrassing circumstance, if you so choose. Once the initial breach occurs, then you have some conscious control of the situation and are able to bring it to a successful sometimes pleasant conclusion.

OK, how long before we get sent to cyberspace and end this thread???

Its official....this thread stinks.....

 

[miked]

Great now I need to have my dry suit o2 cleaned.....

....only if you farted nitrox in excess of a 40% mixture

Actually, change of pressure after eating beans IS a problem. Army pilots are forbidden to eat the MREs (Meals, Ready-to-Eat) that contain beans if they are to fly within . . .cannot remember, 12 hours? 24 hours?

A suit for of methane and ean 40. Now that could be explosive. I guess the argon guys got it right.

Is it a pressure problem or is it a rule that copilots thought up.
