Not much. You really shouldn’t be going into grain bins, and if you you do get stuck you should call for help and shut off anything that’s making the grain move. If you have to go into the bin for some reason, there should be someone outside with you and you should have a safety rope to help pull you out. Covering your mouth won’t help for long if at all. Someone will need to put up fans to ventilate the bin. You will suffocate in a grain bin and I’ve lost friends who went into bins.
So what do you do in this situation that you’ve fallen in to grain?
I imagine you might still be able to breath if you can keep your mouth covered.
Edit: I’m getting downvoted because I’m not familiar with grain suffocation? Ok there. 🙄
Edit again: oh they stopped. Thanks for not being jerks, everyone!

Every once in a while you read a story of someone that survived, it’s usually because they had a mask of some sort that filtered enough air through the grain so they could breathe. Like this guy: https://www.agweb.com/news/livestock/pork/descent-hell-farmer-escapes-corn-tomb-death
Sounds horrible!
