QwertySanchez posted:Oh and carbon dioxide in water turns into carbonic acid too so whatever they didn't breath in above the water's surface was probably what was responsible for the chemical burns a couple of people had too. Even if the carbon dioxide reached equilibrium in the water, it would be no stronger than a carbonated beverage. Mountain Dew will dissolve limestone, coral, and teeth eventually, but causing chemical burns in a matter of minutes is beyond its capability.

Isn't industrial dry ice unsafe for food usage due to potential contaminants? What are the chances she bought pure food-grade stuff as opposed to the cheapest she could get in bulk?

It can contain oil residues, but I doubt it would contain anything caustic. If they poured dry ice pellets into the pool, it might have simply stuck to skin..

Platystemon posted:Even if the carbon dioxide reached equilibrium in the water, it would be no stronger than a carbonated beverage. Just quibbling here because the only burns here would have been frostbite but also want to point out carbonic acid chemistry is awesome, dynamic, and still being completely understood. Dry ice in water is a pressure where it's doing cool things you'd never see soda do, but also not exactly going to contact acid burn either.

zedprime posted:Equilibrium with what? The soda isn't even at equilibrium after you open it which is why it fizzes. an atmosphere of pure carbon dioxide at one bar, the worst‐case scenario for the gas hovering over the surface of the water Soda demonstrably has a higher concentration of carbon dioxide dissolved in it than is possible at one bar. That’s my point. It’s at equilibrium at something greater than atmospheric pressure. Google says four or five bar absolute. zedprime posted:carbonic acid chemistry is awesome, dynamic, and still being completely understood. Dry ice in water is a pressure where it's doing cool things you'd never see soda do How so? My naïve understanding is that it sublimates at no more than atmospheric pressure, plus a few centimetres for the thickness of the chunk of dry ice. Is it capable of supersaturating the water or what? Platystemon fucked around with this message at 13:59 on Mar 1, 2020 |

Platystemon posted:an atmosphere of pure carbon dioxide at one bar, the worst‐case scenario for the gas hovering over the surface of the water Carbonic acid is polyprotic and the different forms have very different water chemistry so different concentrations behave differently as each type becomes more or less prevalent. Doing the full p chem diligence on pH and solubility is a nightmare. But we know enough qualitatively to rule out acid burns without doing the gymnastics

For one brief moment, I thought, "Better grab the extinguisher." Then he started blowing on the gasoline fire in an attempt to put it out, and I was like, "Oh, right. Why would he have an extinguisher?"

EKDS5k posted:Goddamn. Someone in some incarnation of this thread said it: "Farmers, famously known for making it to old age with all their fingers intact." This is the exact type of thinking that gets people maimed and killed. You know what you're doing, except that you have no idea what you don't know. Like the farmer who died from CO poisoning from using a pressure washer inside a tank, along with his wife and friend who rushed in to try and save him. Or you are aware of the dangers but haven't accounted for the unexpected. It's perfectly safe, until you slip and reflexively try to grab a spinning PTO shaft that has no guards on it. You're close but you missed it. We are very aware that we may die today. We get used to it. I haven't had to farm in many years, but every day was based around, "How will I die today?" There's too much work to worry about OSHA. We risk ourselves. We do not risk others. We tell others to retreat to a safe 100 foot distance. You accept personal responsibility for your own death. The work just needs to be done. Safety would make it impossible. There's no money in it. At best, you're turning a loss of $100,000 a year. Safety would double the loss. You just have to work and that's how it is. We're well aware of enclosed space danger. We don't weld old gas tanks without filling them with water first. We do wear respirators around chemicals. We do keep deluge showers if necessary. You never touch a spinning shaft. You tuck your shirt in, role your sleeves up, and tuck your pants into your boots. You never step over a PTO. You inspect every piece of equipment before you use it. Maintenance is half your job. You do take the side shields of the big roto-tiller because they cause the blades to jamb. The trick, is to not shove yourself into running equipment. There's a switch on your right side that disengages the PTO clutch. Use it. The fact is, you don't have the money to make everything perfect. You just have to remember what you did. I used to work with a chaff saver that wanted nothing more than to murder you. I knew it wanted to murder me, so I knew how to jamb the latch with a piece of wood so it wouldn't cut me in half. That's one of dozens of things that wanted to murder me. That's why the uninitiated need to stand back.

I don't know how to fix the systemic injustice(s) that lead(s) to farmers feeling they need to adopt unsafe practices in order to work at their jobs. I don't even know what they all are. But I'd sure prefer to live in a world where people don't have to do unsafe things.

If following proper safety precautions costs you $100k/yr on top of a loss of $100k/yr, you should not be in business.
