@@katiebarber407 oh it gets worse, I found out from a video by the iilluminaughtii (she focuses on researching scams and shady business practices), that the No Child Left Behind act contained a clause allowing military recruiters to demand private information for students that didn't perform on their tests so they could target them for recruitment. Someone in congress got their panties in a twist because they interpreted schools wanting to protect their students as schools having a vendetta against the military. So they got that one added just to make sure schools couldn't say no. If I ever find out that happened to my personal info at my school, I'm going to try and sue the Military for invasion of privacy. Especially if that clause is still on the books. Its absolutely disgusting that poor kids were made to take a rigged test that favored rich kids, then targeted by the army because they were too poor to do well, and tricked into going to iraq and afghanistan to possibly die. Let alone closing or cutting funding for schools that couldn't improve, this last bit about the military pretty much threw me into a rage.

Methyl mercaptan is *incredibly potent*. It can be smelled down to parts per trillion. I'm sure there's a large margin of safety until you get to toxic levels. When food rots, it produces things like ethyl and methyl mercaptan and it is very important that humans be able to detect it in very tiny quantities to warn if food is too far gone to eat.

[@DrewskisBrews]

Seconding your observation about other hazards - 'chemically inert" does not automatically mean 'harmless' . For example, any type of gas has the potential to asphyxiate. Asbestos, too, is basically inert, but has the ability to cause damage at the cellular level because of its mechanical properties. I saw in the news recently that titanium dioxide is proported to be harmful as a food addative, but I'm still skeptical about that one.

I did some work with Am-241 sources a few years ago, and in the course of doing the safety risk assessment document I found a US safety report about someone who had swallowed one and (fortunately) lived to tell the tale. Am-241 is expensive - $1500/gram, so the source foil is actually an alloy of Am-241 with gold, rolled out very thin and plated with silver on one side and palladium on the other. And thanks to the fact you can roll metal foils really thin, a single source costs less than a dollar!

Unless you scratch or etch the top layer away or get the foil hot enough to melt the silver or gold, the americium is unlikely to leach out. But putting it in your vape is still incredibly stupid. I have such a source I use for calibating my gamma spectrometer, but it's epoxied to a 1mm thick aluminum business card laser etched with the trefoil warning symbol and "Am-241" in large letters, precisely to avoid it getting lost or flagrant stupidity.

In german Highschool (12th and final year), we were supposed to shoot a video for new students who would potentially join the school (4th class). One experiment was pouring ethanol in a large metal tray, igniting it and then blowing magnesium powder from a glass rod into the fire. This whole demonstration was done in a fume hood. Our teacher told the guy who blew the magnesium into the flame to not put too much into the rod. He absolutely loaded that thing and the result was a temporarily blinding, around one cubic meter large fireball, luckily no one got hurt. In the same class, I once somehow got HCl into my eyes (I don’t know how) although I wore safety glasses. No problem because we had an eyewash which the teacher immediately used.

These stories might be a bit less exciting, but a lot of stuff happened at my high school: - Benzene was not allowed in the school at all. However, there were no rules about experiments outside of the school. Guess who had a vault of some banned chemicals in the forest next to the school? A teacher, who then proceeded to show us (safe) reactions with the stuff. - The school had to remove the nitric acid from the back of our classrooms. Why? Well, it got stolen at least once and more importantly some students in the back row thought it would be really funny to just mix up chemicals in a beaker until something happens. The beaker got warm, then a lot warmer, and they quickly dumped the brown liquid down a drain. The school never found out who did it, so no punishments there, but the nitric acid became a lot harder to access. - A teacher instructed us to put something on glass in a microwave (forgot what the chemical was). The glassware exploded. This happened twice before she realized that it might be a good idea to stop the experiment. Stuff that I heard from other schools: - Someone told the teacher and an unnamed student had placed several drops of bromine in the air vents. So, they escalated the situation and promptly evacuated a school of ~1300 people. Several experts came into the school and did a bunch of measurements. They found a ton of alarming stuff (mold in some bathrooms and the likes) but no trace of bromine anywhere.

In high school, the first lab of the year was "distillation of wood'. The apparatus consisted of a test tube loosely held in a spring clamp, with one hole stopper with latex tube leading to a filled inverted jar in a bowl of water. There was a liquid trap proceeding this. The process was to heat popsicle sticks in the tube with a bunsen burner to the point of char, separating and collecting the 3 phases of matter. Some students would allow the jar to rest on the tubing, pinching it (at first this was unintentional LOL), and the nearly red-hot test tube would pop the stopper, launching into flight with a tail of burning wood gas / liquid. We learned rather quickly that POP! from another lab station meant DUCK.

When I was in weld school, we where learning TIG welding. Part of that is to ball the tungsten before welding aluminum because we were using the old transformer based machines. Anyway, we had weld booths that we used as our work area, and the instructors said that pennies worked great for balling up our tungsten. Needless to say a student in front of me was getting carried away, as he was using newer pennies that are mostly ZINC. Now to ball the tungsten, you simply start the arc and pump the pedal to dump a large surge of current into the tungsten to ball the end. That is not what the guy I am mentioning did, HE VAPORIZED THE WHOLE PENNY and inhaled it because he had moved his vent away from where he was welding because it was pulling away his shielding gas. Needless to say he started throwing up and missed two weeks of class because of it. Also burning Zinc coats everything with white Zinc Oxide, the tell tale sign that what you are welding has a galv coating, also the zinc burned with an epic blue green flame because of the copper coating and zincs emissions.

I was outside, in shorts and flip flops because i was dumb and 12. So im sitting there, waiting for the forge to heat up, and i move a piece of wood on the table i was using, only to find out a swarm of ants had it made their home and were now rapidly vacating the premises. I panicked, dropped the metal, kicked my legs, flip flops flew off, tried to run, then I *stepped* on the metal. If it werent still warming up, i'd probably be crippled. Second! I had a much better safety mind at this point, and was hot cutting a piece of metal with my brother. note that this was one of my first times using a hot cut chisel, and this specific chisel dulls very quickly. What had happened over the course of the cuts, is the edge had been so dulled that it was now round. Couple that with the now too-cold work piece, on the final hit, the work piece snapped free, shot across the shop and hit my brother in the leg. LUCKILY, he was wearing full length pants and it only bounced off. so yeah mandatory safety gear in my shop is now long sleeves, long pants, close toed shoes and non-flammable materials

For the stench measurement: the air handlers for the mines will be moving air at a certain mass flow rate, measurable by the electrical demand on the motor. From there it's a concentration problem. Alternatively, the idea of "toxic stinky gas is better than getting caught in a mine fire" might make them skip that step. I had a teacher who previously worked in lead mines in Idaho.

The Am241 in ion sources is apparently sputtered or smashed onto a metal substrate and then laminated over with something inert like gold, so as long as you're not scratching at it or heating it up substantially it's supposedly pretty stable. The source material doesn't look very disturbed, if he's lucky all that happened is it got hot enough to oxidize the surface of whatever the outer cladding layer is (or toast it if there's some lacquer coating on top) and all the Am stayed embedded. Would be interesting to have a before and after of the activity of the button.

[@AlChemicalLife]

yeah , I don't think he messes with the actual foil of gold mixed with Am241 dioxide. the 2 are pressed and heated together so unless you dissolve the gold you're not likely to get any Am241 out of it. also it has a top layer of foil ( on top of the other foil disk with Am241) which usually is palladium.

[@rickfreeman5866]

Agreed, the heat in burning chamber not enough to release Am241 from encapsulated state. Still, an eBay detector could pick up the small gamma component if source was deposited in lungs. A small price to pay for peace of mind. If present, the alpha decay would be deadly over time but could be located (by gamma signature) in a major hospital with Medical Physics Dept. and followed by lung surgery to remove.

Dad's chemistry lab (small highschool, student body of ~70) had a bunch of nasty chemicals left over from previous teachers. When the Department of Environmental Quality (DEQ) did a sweep, they discovered a rusty gallon can of carbon tetrachloride likely over 50 years old. It was only being held shut via a rusty bottle cap; stored in a cabinet at the back of the room.

[@joeylawn36111]

Also, I'm fairly sure the main risk of Americium from a smoke detector if ingested/inhaled would be the radioactivity. This is because the amount of Am-241 is extremely tiny (290 nanograms) - not enough for chemical heavy-metal poisoning, but it's also extremely radioactive - a strong alpha particle emitter - 5 times more than Radium.

Antimony metal gets way too much flack for being toxic. Elemental antimony and antimony oxide are fairly nontoxic and are not well absorbed into the body. It’s used in food safe (lead free) pewter. In high school, I blowtorched a bunch of antimony and cast into a nugget. I carried it around a lot with me in my pocket for years and frequently take it out and play with it.

I think a lot of people confuse the biological effects of arsenic and antimony which might be the cause of this. Always confused me why people are so freaked out about antimony when, as the metal, it is much safer than lead.

[@vitriolicAmaranth]

One I like is people finding out Tiger's Eye, Nephrite Jade and Serpentinite are asbestos and getting freaked out because they don't understand what it is that makes asbestos dangerous or why having it in the form of a cut and polished stone presents no danger whatsoever (unless you deliberately crush and grind it up, which is incidentally almost impossible without special equipment in the case of nephrite, which can be carved very gradually by abrasion but is one of the most difficult naturally-occurring minerals to crush).

over here in Bongland, methyl mercaptan and similar compounds are added to domestic gas supplies because their odours can be detected by the human nose at extremely low levels (as in, parts per billion), and if you can smell mercaptan-infused gas, that would otherwise be odourless, you can detect a gas leak long before it becomes dangerous with that in mind, your man's story about the mine at 2:19 makes perfect sense - a little stench gas goes a very long way funnily enough, the same is true of the mercaptan that acts as the principal flavouring/aroma agent in grapefruit; for some reason, the human nose is extraordinarily sensitive to it

Work as a Sanitation worker at my college. We are currently cleaning dorm room bathrooms in prep for the students, and go through a lot of industrial cleaner while cleaning since a lot of students don't clean their bathrooms throughout the year. I wear my usual ppe (splash goggles, and gloves) while cleaning. After a month, my throat became really sore and I was coughing a lot. I thought I caught covid, so I took some time off until it went away, and when I came back, I was taken off of bathrooms and put on a painting crew. I was recently using the cleaner again to clean bathrooms and my cough just came back up, so I checked the bottle and whaddya know, its HCL. Needless to say, ill have to add a mask to my list of ppe to wear while cleaning, and recheck the MSDS to see if it says anything about breathing in fumes.

[@tookitogo]

Yeah, HCL is used in a number of limescale removers, since you need acids to dissolve them. Also, #lfmf : don’t wipe metal surfaces down with dilute limescale remover solutions. The water in the thin film of solution will evaporate quickly, becoming more and more concentrated to the point it can damage the metal…

He had to stop making things because as it turns out, when you live in a rural suburbia, your neighbors tend to not like the sound of you hitting metal, repeatedly, for hours on end.

The only time I taught practicals for biology freshmen, one pair of students was... special. When it was time to do a simple acid-base titration, the students were supposed to use 50 mL burettes. The lab had tiny light chairs with a diameter of maybe 25 cm. From the other side of the lab, I saw the taller of the pair climbing on top of one of these chairs. Not good! Coming closer, I saw that he was holding the biggest pipette in the student set, and was proceeding to stick it into the burette. As tall as he was and standing on that puny chair, he was still pushing the burette, and was about to topple it over even if he managed to not fall over with his chair. I grabbed the burette before it got knocked over, told him to remove the huge pipette from the burette and get off the chair, and then asked for an explanation. "Well, you know how this is a quantitative experiment, and you explained how carefully we must read the initial and final positions on the burette?", why yes, I replied, "Well we were going to use the 25.00 mL burette twice to place exactly 50.00 mL into the burette". Obviously, detailed explanations had been provided about the initial level in the burette only having to be below the first gradation, not necessarily zero (that corresponded, of course, to 50 mL plus lord knows how much volume was below the last gradation). And obviously, long-winded explanations were promptly given again. BUT!!!!!! That same thing (well, almost the same) happened a second time!!!!!!!!!!!!!! Not ten minutes had passed, and Mr. Tall Guy was on the tiny chair, with the biggest pipette in his hand, again! So I rushed over, asked him to step off, and asked for another explanation. The pair nonchalantly pointed to the burette, which they had topped up, as instructed, from a beaker with the help of a funnel, and said "You see, we've gone over the first gradation, so we must remove some solution".... O. M. G. The experience, for me, had transcended the realm of comedy and is just etched in my mind as one big WTF moment.

[@jeffreyblack666]

I think for the gas used in the mine, they have an incredibly low odour threshold, much lower than the exposure limits. And once you smell it, you should be leaving the mine, so the time of exposure is much less. That should overall make it much safer than a toxic gas, potentially at high concentrations, which you can't smell and therefore remain exposed to, or potentially explode.

Blacksmithing story: I was in the 6th grade, and had taken up and interest in blacksmithing. I went to a local hardware store to pick up a bucket, a pipe for an air duct, and plaster of paris. I successfully built a small forge, and within two weeks, this happened. I had finished hammering down on a piece of round stock, and reached for my pliers to put it back in the forge, when, instead, my left hand landed on the (still piping hot) piece of round stock. The burn wasn't that big, but it hurt like nothing I'd ever experienced before. At least I had a good story for my classmates the following day. I also have a cannon/black powder story if you want to hear that.

[@totallynotdelinquent5933]

I was in High School chemistry class and we had a lab about burning magnesium. this involved burning a few small pieces of magnesium, lithium and zinc ribbon/foil (~2-4mm) in a Bunsen burner flame to view atomic emission. We were all given glasses so we wouldnt go blind and told to keep them on the whole time. One girl decided to set a huge piece (like 4 inches folded on itself) on fire without her glasses on...

Okay, so when I was in inorganic chem, one of my assignments was to make a green light-sensitive iron complex. It's used to... I guess measure how much light hits a surface? I don't really remember. It was pretty standard fare for a while, I precipitated the complex out of solution and poured the suspension through the filter paper to do a vacuum filtration. There was a nice, relatively dry green powder sitting at the bottom of the funnel, ready and raring to degrade under harsh light. Now, I have no idea why I thought this was a good idea, but instead of just pouring out the green powder like a sane person, i tried to... reach in with my finger and scoop the filter paper out of the funnel. With bare hands. I ended up spilling the complex all over the table and killing my yield, which had been pretty good up to that point. I'm a competent human person I promise.

[@remanjecarter2787]

Not blacksmithing but silverwork if i remember correctly. Some of my most unsafe moments not gonna lie I had a piece of metal i had been rolling out and after a heat treatment it wasn't glowing so i reflexively went to grab it with my bare hand. I actually left my fingerprint burnt onto the metal not just a smudge from where my skin touched it. And then a few years later i did something similar but instead the notable part about it was that instead of the smell of burning skin it smelled like eggs. Not rotten eggs like what I've been asked about whenever i told the story, just like eggs cooking normally which was interesting to say the least Another time i was refilling my butane torch which unknown to me had spilled a LOT of liquid butane onto the surface i was working on. When i went for the test light of the torch i got a fireball to the face and the front part of my hair was slightly on fire, and my nose hairs and eyebrows were a bit singed too but nothing serious Other than that there's not much else besides a few liquid metal spills where i got to see an interesting version of the leidenfrost effect where instead of a cool liquid on something hot it was a hot liquid metal on a wet surface. It acted very similar but it reminded me more of how sand falls on a smooth surface except it was a larger bead splitting into smaller ones on impact

In my first year of undergrad research, I had my own Schlenk Line so I could perform my air-sensitive polymerizations outside of the glovebox. It was really late one day, and being new and inexperienced I turned off the vacuum pump without lowering the liquid nitrogen dewar cooling the trap. The next morning I arrive in lab and figure out that I condensed about 500mL of liquid oxygen in the cold trap (I guess I had a leaky line), which essentially means that I made a bomb that could’ve blown up the whole lab and maybe even more. Thankfully my mentor was able to take care of the liquid oxygen, but only after he took a picture of it in the trap lol.

Art isn’t typically seen as a high risk profession but I regularly work with cadmium and cobalt pigments and one of my professors is a sleep deprived state (not for teaching thankfully) decided to put some soft body (refers to the thickness of medium) cadmium into his airbrush. Cadmium pigments in a medium are pretty safe but in power form such as the actual pigment dust and soft pastels or if you aerosolize the pigment ups your likely of exposure a lot. So basically he probably is getting cancer just a bit quicker. Also basically every oil painter has almost passed out from solvent fumes once in their career.

The "stench gas" thing, it can basically be smelled at PPB but is only toxic at PPM. Compounds like that are usually common byproducts of putrefaction, and not necessarily abundant ones, just very specific. Thus our noses have evolved to detect the faintest whiff to prevent us from inadvertently poisoning ourselves by eating spoiled foods.

[@l.r.oliveira3005]

I work at a natural products lab. We run column chromatography every day and use a lot of solvents, including chloroform. So, I was distilling some impure chloroform and added 1 L of old chloroform (maybe over 10 years old) to the distillation flask. The fume hood was on, so I didn’t notice anything strange. After the distillation, I stored the chloroform on a 5 L gallon. The next day, I was alone in the lab and opened the gallon outside the fume hood, since my chromatographic column was too big for it. I was hit by a strong sweet and acidic smell; it was like a punch to the face. I started coughing immediately and felt like my throat was on fire. I run out of the lab to breathe some fresh air (in the emergency exit) still coughing and unable to breathe. When I recovered, I turned on a fan in the lab to get rid of the smell and sealed the gallon. On that day I learned that chloroform can turn to phosgene, a WWI chemical weapon and that I probably breathed some of it. It didn’t cause further consequences and I learned to never use old chloroform again.

Ethyl mercaptan seems to be way less toxic (NFPA 704), and in underground mining, they actually use it as a "stench gas" as an alert system in case of emergency. In fact, it is law in Ontario they use either ethyl mercaptan or an equivalent in an alert system.

Typical Am241 in a smoke detector (a modern one) is about one microCurie. If vaporized and inhaled, it would cause 166 times the maximum annual dose to bone surfaces, or if in a chemical form that didn’t absorb into bone surfaces, only 100 times the annual limit. Fortunately for the vaper, the boiling point for americium is over 2000 C.

[@galliumgames3962]

At 1 microcurie, your body will become 123% more radioactive (the human body is about 0.8 microcuries, mainly from K-40 and C-14). If all of it is absorbed, this will lead to a slightly higher incidence of cancer, but nothing immediate or dramatic will happen. There is still absolutely no reason whatsoever to vape americium though.

[@AlChemicalLife]

His lifetime dose would be 4.4Sv if he somehow managed to vape the whole Am241 source... that's not very pleasant 🤣 his chances of cancer probably would go up 10 fold maybe 100 fold. That lifetime dose is equivalent to 44,000 chest x-rays for a lifetime or 367 full body CT scans for a lifetime.

[@zerumsum1640]

for how they control the amount of "Scent alarm" in mines, I'd assume they meter out the release into the air getting pumped down into the mine that it's not going to cause issues. Most mine airflow goes from the entrance to the working face in terms of airflow, that way any airborne hazards (like hitting a gas pocket) don't go the same way as the people trying to escape the hazard. Either that or they have wire triggered stink bombs around the mines, but i'd bet they just meter it into the air intake as the vents handle the distribution (have to have full air circulation in a mine so you don't wind up with a pocket of bad air) and it'll do it pretty damn quick too as most mines use diesel equipment and thus have to have at least 0.6 m3/s of air for ever kilowat of diesel power they have underground. That isn't taking into account breathing air and other things like air powered tools which are used in some places to avoid needing to burn as much diesel. Edit: Storytime! Ok so in college i took forging as part of a required metallurgy course and during this we each got to sand cast, forge, and machine a chisel, wrench, and machinist's square. pretty basic stuff, make a ceramic mold to make the stock, fire it in the kiln, pour molten steel into the mold, let it cool, and then forge and grind to shape. Well, thanks to another classmate's forgetfulness, things got a bit... jumpy on me. We'll call him Dan. He did step 1 fine, but improperly fired his mold. Now, firing here does 2 things. It burns out the wax used to make the mold's internal shape, and most importantly it removes the water from the ceramic paste/slurry we used to make the mold. He only stuck his mold in the kiln when it was cooling off to melt out the wax. Those who have cast metal in the past can already see where this shitshow is going. Well, time comes to pour and we head out into the hot work area of the campus. Teacher is already out there and has us set our molds up in metal buckets of sand so they're nice and stable, and things cool at a good rate. I notice as I'm pouring sand around my mold that his looks a touch cracked, and is... crumbly? odd but i don't think much more of it because at this point everyone's molds were fired... right? My pour goes off without a hitch. If you ever get the chance to cast metal, do it. It's hard work but very fun, and if you're lucky you get a tool or something that'll last. everyone else's has been fine as well. Then it's Dan's turn. The instructor has to take a call, so he gets me and another student to supervise as we're the ones he didn't need to help with the pours. the other guy had experience casting before, and I'd seen enough videos to know how not to kill anyone. We'd also been helping the other students by that point. Well, we get set up and force Dan to put on his PPE (he was a massive vegan and hated wearing anything made of leather). Dan pulls out the crucible almost dropping it 3 times he was so nervous, so i take over as he's way too antsy to be handling molten metal. I line up the pour, and i watch through my face shield as the glowing yellow stream of liquid steel falls down towards the mold. Now, we're going to pause the story a moment so i can explain something. For those of you that don't know, molten steel is at a minimum of 2500°F or 1371°C. If there is any water left in the mold you're pouring it into, this water will flash boil at those temperatures and explode. With lead, as was the case in the story in the video, this will cause the lead to splatter around the room and that's only at around 320 - 600 celsius. In Dan's case, there was a LOT of water left trapped in the thick layer of unfired ceramic. The outer layer was dry, which probably saved my ass, but once the heat reached the damp layer that started turning to steam, creating pressure and a hissing noise. As soon as i heard this i stopped pouring and stepped back. Damn glad i did too because not a second later the contents of the bucket (including the molten steel) erupted loudly into the air sending everyone running. my PPE took the worst of it, but i still have a shiny spot on my arm where a bit of the steel made it through and burned me. I'm glad i was using one of the metal face shields, as the first plastic layer and the glass in the lens had been destroyed by something hitting them. Rung my bell pretty good too. 'course the instructor comes running out asking what happened and all i could reply was "I have no fucking idea. Also, some steel made it through the arm of the coat, where's the burn cream?" we figured it out after the ceramics instructor came in asking who left the wax in the bottom of the kiln as that should have burned off. Dan later profusely apologized, he had missed the class where we went over the procedure and thought that everyone was just putting their molds in the kiln to melt out the wax. He got one chance to redo it (under close supervision) and nailed it that time.

Might share two short stories from my middle school - nothing major, but still, perhaps some folk can have a giggle at them In one of the classes, we were learning about sodium, and how it reacted with water. So, since I was one of the best students at chemistry at the time, I would often go to the teacher's desk to make small experiment. I simply cut a tiny chunk of sodium with a kitchen knife, and put it into a large glass bowl of water, to see its start reacting, nothing special. But the thing is, I didn't really know what a "tiny" chunk of sodium should be, so I made it bigger than I should've, and it ended up exploding after a while. The teacher then told us not to move and to carefully look for the chunk of sodium to take care of it. We couldn't find it on any desk or anywhere on the floor - and after I looked up, I found where it went. It launched vertically up, and ended up making a small crater in the ceiling. Nobody was hurt, but it's one of my most memorable moments of middle school chemistry classes. In fact, it's half of the reason why my username is what it is, I still have a thing for this metal. And - allegedly - the crater was never taken care of, since it wasn't *that* big, so it's in the ceiling to this day, a decade or so later. (In case you're curious, the other half is a short sci-fi story by Stanisław Lem that included sodium, but, I digress.) The other story is from my chemistry teacher herself. It happened back in the late 80s or early 90s, when some student told her that they have a bit of mercury in their house that was not in use by anyone, and they could bring it to the class, perhaps it could be used in some experiment. The teacher said, sure, she assumed it would be a tiny vial of mercury from a broken thermometer or something like that, nothing major, just a tiny amount that she could take, so it would at least not hang around in a random house. The next chemistry class, the student brings the mercury to her. And it was not a vial, they brought a bloody mason jar full of mercury, and a large one at that. She asked them where the heck did they get this stuff from - they didn't know, it was just, there, in their house, and they asked their parents, who said they could have it and bring it to chemistry classes. My teacher was still shocked a couple decades later, and when this happened, she was especially terrified that the jar's bottom might break off at any moment, since, y'know, mercury's pretty heavy. She handled it carefully, and handed it away to some laboratory her friends worked at to take care of it, since she was NOT keeping all that garbage around. Middle school chemistry classes are some of my fondest memories I've had from all my years of education, and these two stories are part of it.

We had the CCl4 funsies, how about some phenol now? One funny observation with phenol can be made in molecular bio lab. We use a mixture of Chloroform, Phenol and Isoamyl Alcohol in DNA / RNA extraction protocol, it forms an OBVIOUS two phase system with phenol layer being the lower one, which is the part you're supposed to use in the protocol. Over the years we are yet to see a student who would not instinctively shake it to mix without even asking, which is exactly what they are not supposed to do :D We have to keep a hidden 2nd bottle of it in the fridge just to have a well separated one in case someone does it again. (It's not like the protocol won't work when using a shaken mixture but it's suboptimal yield / purity, and we keep the phenol under chloroform layer after mixing and saturation cause it preserves much better). Another semi-yikes story I can share is with preparing the phenol solution for this protocol. Pretty casual stuff, you just melt some phenol, wash it with EDTA buffer a few times, and right into the freezer it goes to prepare the chloroform mixture later. We usually do a bunch at once cause it's a pain, and small batches take just as long as large ones (still not a lot, in the order of 500-1000 mL at most which lasts for a few years). Anyway, for the separatory funnel mixing the PI told me to make sure the stopper fits the funnel, cause there are some bad ones, and to stop and wash my hands and get a better stopper if i feel it's getting wet. But thinking naah i have gloves, ain't nobody got time for that i just used a towel to hold the stopper end in case it'd get wet - of course i picked a crappy one and it had a tiny leak so it did get wet but i couldn't feel it in the gloves. What i didn't realize is that the nitrile gloves will get absolutely destroyed by the still warm phenol, and when i finally got to cleanup i had to wash off the disintegrated pieces of gloves off of my hands. ALWAYS ALWAYS check the glove compatibility if you're not sure :D if I did it bare handed i would at least know it's wet and stopped immediately, instead i had to deal with my hands reeking of phenol and skin being super dry cause of the ethanol i used to wash the phenol and glove pieces off. Also a fun idea if you have no clue what could be a wedding gift for mol bio researchers, the reason we make our own phenol solutions is my PI got 40 kilos of super high purity phenol as a wedding gift from his former boss in a reagent supply company. FR works much better than the premixes you can buy nowadays, especially for our own optimized protocols.

The mine I worked at back in the 90's had pressurized bottles of ethyl mercaptan (remote electrical release/local manual release as a backup) on both the intake fan for the fresh air raise as well as on the header that ran from the compressor house to the underground workings. It was explained to me that they were sized such that they would fill the entire mine with a very easily detectable amount of gas, while still being below the danger threshold. Considering the alternatives (collapse, fire, explosion, SO2 & NOx, flooding), and the fact that the volume of the mine naturally increased over time, I'm sure they pushed up against the upper limit as much as could be considered practicable when they installed the system. Previous to it, there were glass bottles of mercaptan that the surface crew would throw into the intake fan, and those continued to be stored in both the shift bosses office in the headframe as well as in the security gatehouse, just in case.

I set it up, lit it, and well, I'm pretty sure the mix was perfect 2:1 ratio as there were 3 bits of tripod rocketing horizontally across the tennis courts as it blew out the welds. No-one hurt, one bounced off the fence and due to lighting between the legs none came my way, but from then on new policy was to use the tripods where the top was a single piece of metal rather than formed from 3 pieces or bent metal welded together.

I have a story from when I was a dumb young student who didn’t take lab seriously. Allergies were getting to my eyes, and I had been lifting my goggles all day to rub them. We were working with concentrated H2SO4 (16m I think) and I didn’t think much of it. I was about to rub my eyes again after I tested pH. With one hand I grabbed litmus paper and the other I lifted my goggles. At the last second I noticed the paper was bright red from the insane amount of acid my gloves. I think I should be blind, thank god I randomly looked before doing something that stupid

I also hav egot quite some stories: - One time in the building next to us (which was a different school) They did something involving bromine where the teacher thought it would be a good idea to let a student hold a Beaker with Bromine and do the reaction... the slipped and dropped the beaker which resulted in the school being shut down for 2 weeks. - another time i was helping our chem teacher sorting the chem cabinet and we found some very interesting chemicals there like half a fucking Kilogramm of Potassium permanganate and like a completely oxidized block of sodium and some carbon tet - Once there was an "explosion" in the acid cabin because someone didnt ventilate the pure nitric acid and the No2 blew the cap off and blew the bottle into smithereens

6 yeas ago I was preparing nitration acid for the whole hall. Everyone gave me their beaker and I mixed the chilled Sulfuric and Nitric acid (with the thick black rubber gloves on inside the fumehood with my upper body behind the lowered glass shield). The first beaker fine the second, third and fourth also fine but one the fifth one I just hear a small bang, and the whole fumehood is filled with brown nitrogen oxide.

Obligatory not a chemist. I was in a microbiology lab during my undergrad and it was my first time working on tissue culture. They started me out with culturing rabbit kidney cells since they were easy to maintain and hard to screw up. Later on I was supposed to treat glioblastoma cells with temozolomide to generate a chemo-resistant cell line for a study. I was aspirating out some old media from the flask of cells and accidentally stabbed my arm with the aspirating needle, enough to puncture the skin. The professor was watching me do it and we just looked at each other and had an “oh shit” moment. We washed it off for several minutes, but luckily there weren’t any dangerous chemicals since it was basic DMEM. It only occurred to me later that day that if I were working on those glioblastoma cells, I might have exposed myself to chemo and more scarily inoculated myself with an aggressive form of brain cancer.

I have a boneheaded story. Last video, I shared a story involving chlorine. The theme hasn't changed... I was in middle school (7th grade I believe) and I read about mixing acid and bleach. Of course, with me being the dumb teen I was, I decided to mix them together. I got a hundred mLs each of vinegar and bleach (damn that rhymed) and mixed them together. A few seconds afterward, it gave off a small amount of green gas, then it picked up steadily. Soon it looked like I had an XXXL size smoke bomb burning. My dad came home, and he saw the cloud of chlorine. He flipped his lid, and I still hear about it to this day.

As a kid I sprayed canned air upside down in a soda can I cut in half, then tried to ignite it in my dad's garage. I was expecting it to just I dunno, boil off, I thought they used inert gasses in canned air. Then my eyes and lungs started to burn. I tried stomping the fire out and instead spilled the halogenated hydrocarbons that I did not know were halogenated hydrocarbons all over the concrete, prompting them to spread out, evaporate, and burn even faster! I ran out of the side door of the garage and stumbled on my way out, landing on the grass, heaving and gasping heavily for a few minutes. I didn't tell anyone, I was lucky nothing else caught on fire. I punched in the code to the outdoor garage opener later to make sure nobody else got exposed.

Probably way too late, but will try to contribute my part. So, obligatory, not a chemist, but a former electronics repair tech in a third world country, and had a fair share of accidents. 1) In one of the places i worked, a colleague tried to recover data from a damaged laptop, the battery has been holding it's structure just good enough to combust right after removal and smoke up the place in an unventilated room with no sand bucket, we both had to leave it burning there on the metal table and run out. All my cloth items stunk of burning lithium for the next month, luckily nobody was injured; 2) Had a fairly big blob of molten solder shoot out right into my eye, somehow reacted in time. Now i have a scar on my eyelid and a story to tell; 3) This is commonly overlooked, but this is why you don't wear flip-flops in commercial environments: a capacitor i was trying to remove from a board, exploded in a violent fashion, showering everything under it in boiling electrolyte, thankfully i had socks on; 4) Occasionally we had to melt plastic to make a patch or reinforce structure on some plastic parts, didn't really have any good methods of doing so, so a fair bit of it burned and the room had to be vented out; 5) Me, being stupid back then, tried to stop superglue from bonding by pouring acetone onto it. I think this is where i've got my persistent cough from, because i had a violent reaction for half an hour after smelling that; 6) Had a 10L canister of isopropyl alcohol knocked over in the shop right when the whole deal with the facemasks started, so basically had the floor accidentally perfectly disinfected; 7) Had several accidental acetone spills on the desk, that i've noticed only after an hour or so, when my arm was basically soaked in it; 8) Had several electrecution attempts from computer power supplies, still have small marks of electrical burns from some; Left the field last year because of professional growth aspirations, with some permanent damage and a lot of experience. Moral: try to think what you're doing, and have safety practices and equipment in place, because any of the incidents i've had could've been a lot worse if i was less lucky and/or careful. Considering the power supply experiences, it's a miracle i'm even alive. Gladly, moved to an industry where the worst i can do is accidentally bring down a website for about an hour.

In my freshman year of high school, I had a physical science teacher who was, shall we say, a little crazy. There were no less than three unintended fires over the course of that school year. For one of those, he was showing off the reactivity of the alkali metals. Starting off with lithium, which just did what lithium does. He wanted to go on to sodium, but, as he said, "The chemistry teacher has all of my sodium, so we'll just move on to potassium." He meant to get just a tiny bit of it, but ended up tossing in what amounted to a tablespoon of it into the sink, which produced a pillar of flame instantly. We were all amazed at it, and near the end of the period, he happened to look up to see the ceiling above the sink was charred. He simply said, "Uh... If anyone asks, that was already there." On another occasion, he had decided to perform an experiment just for our class. According to him, he had done it before in college and it produced a boom so loud that it shook all the windows in the science wing and security thought that a bomb had gone off. It was electrolysis of water to collect the hydrogen into a bottle and set it on fire. When he had done it in college, it was a one liter bottle. For us, it was a three liter bottle and he had had it running overnight with zero supervision, just sitting there on his desk. After he finished explaining it to us, he pulled out what I can only assume was the longest spark igniter in the world and attempted to light it. After four or five sparks, it just gave off a gentle "whoom" sound. No boom, so he tried again. And again. And again, each time producing nothing more than that gentle "whoom." He stands there, thinking for a moment, before stopping mid-thought and saying, "Oh. Nobody light a match, and someone open the windows. See, uh... Plastic, while we might see it as rather solid, can be quite porous and is definitely not completely airtight. On top of that, hydrogen atoms are very small, so there's possibly a bunch of hydrogen in the room." Our first interaction with him was just him playing "Guess the Gas," where he was running some sort of gas through a bubble solution, scooping up a handful of it, and then lighting it on fire... Directly in front of students' faces, going up and down the aisle, asking, "What gas is this?" I certainly didn't want a fireball in my face, and I could feel the heat of it from across the room, so, just before he got to my seat, I raised my hand and said, "It's methane?" Giving the correct answer, thankfully, got him to stop. If anyone is a mad scientist in today's day and age, it's him, hands down.

[@rojopantalones9791]

As for stories about myself... Well, I am not a clever man. I have been known to just taste unknown items, as, to me, it's rather effective at identifying them. As a curious child with access to even basic tools, that resulted in me finding out what dry cell battery acid tastes like. If you want to know for yourself, lick a Switch cartridge. Just recently, I found a mystery liquid on the floor of the back room at work. I was training someone that night, so she was right behind me as I was trying to figure out what it was. On one of the shelves nearby, we stored motor oil, but it was a translucent, yellowish liquid, so I assume it might've been synthetic oil. I dipped two of my fingers in it and rubbed it a bit with my thumb, and it felt oily, so my assumption felt on track. I proudly announced to my trainee that I was going to taste it, to which she said, "You're going to taste the mystery floor liquid?" "Yes." "Wouldn't it be smarter to trace it back to its source in case it's something dangerous?" "... Probably." Well, I did that, instead. Sure enough, it was not synthetic oil. It was sodium hydroxide drain cleaner, which would've ravaged my mouth and throat, because, mm mm lye. I was 30. While pet sitting for a friend, she had a package arrive that was food for her snake and one of her lizards. Just some frozen mice. I took them out of the package and saw a white brick inside the package, so I grabbed it with my bare hands and held it up, looking it over. "Why does it feel like my hands are burning?" I continued to hold the suspicious brick. "Why does it have some sort of cloud falling off of it?" I continued to hold the brick for a minute or two before it clicked: "Oh. It's dry ice." I was 26. While washing my clothes, specifically my whites, I accidentally splashed a bit of bleach onto my hand. Doing as any person does, I just wiped it onto the tank top I was wearing and went about my business until I noticed the pattern it bleached into it. I thought it looked neat, so, instead of taking it off and applying it to that, I continued to splash bleach onto my hand and smearing it onto my shirt. After a while, I wondered, "Why does my chest feel like it's burning? Oh, well," and continued to do what I was doing. For 15-20 minutes. Then it finally sunk in: "It's bleach, which is a base. My chest is burning because it's a chemical burn." I took off the tank top, thoroughly rinsed my hands and chest in the sink, and then "safely" splashed bleach onto the shirt using the cap. Okay, maybe not the safest thing, but safer than applying it directly to my skin. I was 20 at the time.

i would guess there are charts or something for the "stench gas", but the easier answer is, you better get moving before it becomes toxic, plus you have a second reason to gtfo as fast as you can, toxic gases might be a great motivater that get even the laziest guy moving quickly

[@rokoala2636]

I read up on the methyl mercaptan thing and it seems like there is an "anti-stench" that neutralises the stench gas before the wintergreen extract is released as an "all clear" signal, but I wasn't able to find exactly what the "anti-stench" is. The safety side seems a bit insane to me but if the anti-stench is effective at chemically neutralising the methyl mercaptan maybe it isn't so bad, or at least not as bad as hiding the warning smell behind wintergreen.

[@lefthandedspanner]

also, there are far less offensive reagents than thionyl chloride for making acid chlorides (e.g. oxalyl chloride, cyanuric trichloride) - why is it still the textbook example for this reaction? see also dihydroxylation of alkenes - the Prévost-Woodward method (silver acetate/benzoate) is a much safer and more practical alternative to osmium tetroxide, and you can tune it to give the syn- or anti-dihydroxy product

[@That_Chemist]

It’s a good reaction - it is still my method of choice, although oxalyl is a close second

[@joeylawn36111]

2:52 To answer you question about how much methyl mercaptan - The human nose can detect such compounds at extremely low concentrations. And the gap between stinking everyone out of the mines and actual harm to humans in parts per billion/million is Huge. Plus, Organosulfide compounds are used, _not_ H2S. Organosulfides = All the Stench of H2S without the toxicity at low concentrations. MeSH Odor Threshold: 0.002 ppm: IDLH (Immediately Dangerous to Life and Health): 150 ppm - 75,000x concentration difference.

[@GenosseRot]

Methyl mercaptane can already be smelled at ppb concentration (yes, parts per billion). So just give a drop of it into the air vent and everybody will smell it pretty quickly while toxicity is not even remotely an issue.

When I was just getting started with metal melting (no PPE at the time), I heated up some indium and had the bright idea to pour it onto a flat surface to get a nice little puddle. The nearest surface was a vise, which incidentally had water on it. Pop! None of it hit me, but I'm sure there's still a few bits of it hidden away in my garage. Also the time I wasn't looking and accidentally stuck my finger directly into a blowtorch flame for about 1/2 second before I noticed. The heat didn't penetrate very far, and all it did was turn the very top layer of skin all dry and leathery. It was maybe a very mild 2nd degree burn underneath that.

Tame lab story: As part of an inorganic chemistry lab course we were tasked with the synthesis of metallocenes (the students were put into pairs and each pair had to synthesize a different metallocene). The synthesis is hell for anybody who doesn’t like working with Schlenk lines (me), but at least the product forms as these really pretty, dark green crystals (nickelocene). Nothing went wrong for me and my partner but I later heard that a different pair, who probably had to handle a more sensitive metallocene, had their product spontaneously catch fire. Nobody was hurt and I didn’t get to see it but that must have been scary.

I have a short and harmless, but fun storry. OK, To get this storry you first have to now some stuff first. So, I'm just 15 right now so there obviosly havent been many big or dangerous experiments done at my school, But basicly all of them used ceramic Evaporating dishes at some point. Now, I'm well knowen to be extreamly lucky when it comes to important stuff, but extreamly unlucky whenever there was nothing to important on the line, so Naturaly whenever i did an experiment, the ceramic Evaporating dish I used was just barely still holding together, and always broke just a few seconds after I was done with whatever I was using them for. This reputation went so far, that even all the Chem substitut teachers Knew about that one guy who allways broke the Evaporating dishes(I never got in truble BTW. cause Chem was the only subject I was allways Lucky with the teachers I got). I live in Germany BTW. so the school system is a little different, but I normaly would have just entert 10grade of a so called "Gesamtschule" wich is basicaly a mix between the three normal paths of edjukation you can go after gradeschool. Instead I actualy maneged to basically get a scollarship for a elite privat gimnasium (The STEM orientet path of edjucation) by getting into a Program called MINT+ (MINT is Basically the same as STEM) wich every year gives scollerships to a few esspecialy MINT interested students in all of Germany and they somehow thought I was good enough to get one. Obviously this ment that I wouldn't be able to stay at my current school till the end, but instead had to go one year earlyer and some my teachers gave me some goodbye presents. One of these was my Chem teacher and the Present they gave me was simply a ceramic evaporating dish with the words "Lucky Evaporating dish for (*my name*), may it never brake" writen on it with black permanent marker.
