I grew up where they had a lot of grain silos. People would suffocate in them all the time.  If a person fell in one, it was like quick sand... they would have to empty the entire thing to get them out. Many times a person would pass out and fall in,, and nobody knew they would be missing. until they started to empty the silo, and something would be blocking the tubes. 4951
