I used to work for a big grain company for a short period of time. They expected people to go walk on that sometimes. I know of 2 deaths while I was there.
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.
Can't remember the video where I saw this (maybe smarter every day?) but if you're not completely submerged they can use a tube/barrell they shove down around you and start scooping it out to release you.
There was a guy who got stuck in his grain silo and before calling authorities he made a tiktok that showed him sinking every time he took a breath or moved in anyway. He was surprisingly calm but you could hear panic slowly wave over him as he spoke about how fucked he was. He was later rescued alive and made a very short video saying he survived.
Growing up in a rural farm area, this was not an entirely unusual thing to occur. That always surprised me a little, seeing that it was talked about regularly and a known hazard. It was known well enough that, though I was never a part of the agricultural crowd, I knew the danger silos posed.
So many of them with their wings in weird positions that it must hurt... Then there's others just walking right in like it's a portal. I'm hoping it's not a grinder but just going to a truck or screw conveyer and the birds are (mostly) ok
Can I say I love that last pigeon just walking casually into the great unknown that is that grain sinkhole like it's done with its pigeony existence without it looking like I'm a psychopath?
In a grain silo, the top layer may appear hard and it may appear that everything is solid below you. However, there could be voids and the grain underneath is still loose. You can easily break through, get trapped, and suffocate in grain. This image actually appears to be from the wikipedia I came to link, heh: https://en.wikipedia.org/wiki/Grain_entrapment
Right? Like it's irrational if you don't live or work near a farm but if you do... Man you hear about silo deaths way to often, children being one of the worst ones you see in the news
This drove me bonkers in that movie "A Quiet Place". The physics of the grain were constantly changing on them, at first they were sinking, then the alien was on it fine, then they were on it fine, then they were sinking. It was a debacle and it may have bothered me more than it should have due to the dozens of other plot holes and innacuracies in the movie.
And obstruct grain flow and eventually rip off, entangle and completely obstruct, if not fuck your machinery down the process chain.
The correct solution is wearing a security harness with a cable secured to a hook and having a second person outside the dangerous area to provide help and call for more help.
And i would be suprised if that isnt mandated by law or binding security standards already. Deadly incidents at grain silos, manure bunkers and so on are always the result of violating already existing security practices.
We can and do. Some of them a rectangular or square with trapezoids on the bottom.
Cylinders are strong and make it easy to support the weight, and if you stack it tall it can just be poured into whatever you use to ship it.
Heavy machinery is cheaper now than it was in the past, so if we need to use a different shaped container and use machines to get stuff out, they can do that now without it being too expensive.
All things being equal, people will use the cheapest effective solution. Other form factors aren't particularly safer or anything.
