Also the safety guys are probably jumping at me but pfft as long as you don't get it on your skin you're perfectly fine" He gives a bigger warning to the huge environmental hazard earlier in the video than he does the "will literally eat your bones and kill you horrifically" thing.

My sister and her entire team of 5 people ended up with RSI after the picture library they worked in bought a new system for scanning in photos that required them to make something like 15 movements from keyboard to mouse for each photo. The company ended up paying out over a million pounds as they all had to take medical retirement - my sister ended up having 3 surgeries to correct really serious carpal tunnel. That shits not as spectacular as a wood chipper but it can still gently caress you up.

Raygereio posted:In my experience, they don't check that you're not an idiot when selling you chemicals. This strongly depends on the country. But usually, the big huge suppliers only supply to official research institutes. The smaller ones supply to everyone but have to follow certain laws. Chemicals that aren't very dangerous/are in common use can be sold without trouble. If you try to buy something dangerous such as HF or a potential precursor to an explosive or whatever, the supplier generally has to ask you what you're planning to use it for. They store that information, and forward that, together with your order info, to some kind of government watchlist. Again, depending on the country. I don't know any details beyond that. And then there's the third category of chemicals, which they won't sell at all if you can't show an official permit. These include direct explosives, biohazardous materials, narcotic precursors, and most radioactives. But those are the legal suppliers. If you know where to look, there's loads of semilegal or outright illegal suppliers around who supply everything they can get their hands on to anyone. That's where those idiots who like to tinker with chemicals in their basement get their stuff from. And I'm afraid that kind of idiocy is more common than most people think. There could be an amateur chemist in your block building a bomb RIGHT NOW!

IIRC industrial glass etching used to be fairly gung ho with its use of dilute HF because its non-fuming and burns are relatively minor and self anaesthetizing. Steel pickling to a lesser extent because its non-fuming and relatively strong, but non-fuming solutions share the characteristic that small exposures are usually self anaesthetizing. I think that's where a lot of the epidemiology data comes from regarding hypocalcemia related organ damage and heart attacks, and fluorosis of bones.

Ambrose Burnside posted:nooo noooooooo its exothermic you gently caress Well, gently caress. This is something I need to file in my brain to forever remember if I ever mess with plaster of paris again. Edit: Turns out the so-called "plaster of Paris" I've used from craft stores was just a mixture of flour and water? Nope, looking at some of the exact tubs I've used on Amazon state it's hazardous to the skin. I've always used gloves when applying it for easier clean-up; never knew it was so caustic. Here's a story about the student in question. Also, a student had to have two fingers removed in a similar accident a few years earlier. From there: "The larger the volume you cast, the more it will heat up. Temperatures may reach 150°C/302°F deep within the mass of a large casting."

You can still buy something akin to hydroflouric acid (sold as "glass etching cream") in ordinary hardware and hobby/craft stores, on its own or as part of glass etching kits. As a creme it's marginally safer because you can't exactly "spill" it onto yourself, but you can still absolutely get hydroflouric acid burns if you get it on your skin, and you can also breathe the fumes. http://www.edhoy.com/pdf/5303_53003_53004_msds.pdf The MSDS indicates this stuff contains: BARIUM SULFATE 0-6% SULFURIC ACID 0-9% SODIUM BIFLUORIDE 7-12% AMMONIUM BIFLUORIDE 21-27% quote:ACUTE: Skin, eyes, respiratory system. "Not for children," no poo poo. This should not be sold to adults in unassuming hobby kits. I used to see actual hydroflouric acid sold in bottles in hardware stores for glass etching. I'm quite sure I saw some as recently as 10 years ago. Leperflesh fucked around with this message at 23:42 on Oct 6, 2015 |

HF is the least of your worries when burning fluoroplastics, because it makes the fluorine analog of phosgene. Unless you are hotboxing your nonstick pans you will probably be ok although the old wives tale is that bad cooks with non stick pans have killed a lot of pet birds over the years. A warehouse fire full of halogenated plastics however is a literal hazmat scenario.

zedprime posted:although the old wives tale is that bad cooks with non stick pans have killed a lot of pet birds over the years. It's not an old wives' tale, overheating teflon pans kills birds because of their lung/air sac function that recirculates each breath for maximum oxygen consumption. It makes any airborne contaminant, whether it's fumes or cigarette smoke or whatever, extra bad for them. wikipedia posted:Polymer fume fever or fluoropolymer fever, also informally called Teflon flu, is an inhalation fever caused by the fumes released when polytetrafluoroethylene (PTFE, known under the trade name Teflon) is heated to between 300 °F (149 °C) and 450 °F (232 °C). When PTFE is heated above 450 °F (232 °C) the pyrolysis products are different and inhalation may cause acute lung injury. Symptoms are flu-like (chills, headaches and fevers) with chest tightness and mild cough. Onset occurs about 4 to 8 hours after exposure to the pyrolysis products of PTFE. A high white blood cell count may be seen and chest x-ray findings are usually minimal.

One of my favorite 'Things I Won't Work With" called "Sand Won't Save You This Time" http://pipeline.corante.com/archives/2008/02/26/sand_wont_save_you_this_time.php quote:It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water-with which it reacts explosively. It can be kept in some of the ordinary structural metals-steel, copper, aluminium, etc.-because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.

Personally I just make sure to organize the completely unplanned breakdown of my motorcycle that results in an electrical fire next to an active firefighting squad so they can put it out with sufficient water. You've read this far into the thread, surely you've seen countless examples of people who aren't perfect who gently caress up what should be routine procedures for handling accidents because of panic and adrenaline.

My dad set the carpet outside under his classic motocycle on fire, he panicked a bit but then used a 20 year old fire extinguisher to put it out. He didn't realise it was the carpet, he thought it was just the bike. I told him to maybe clean up the spilled fuel and oil to stop it happening again, maybe move those solvent bottles as well.
