Girl in my undergrad lab didn’t label her bottles correctly so instead of putting some more hexanes over her Sodium she had a bottle of water in her hands and poured half of it into the porcelain dish. It honestly took longer than I would have expected for the sodium to ignite but soon after catching fire it exploded into at least 20 smaller burning lumps of sodium (Our sodium comes in sticks about 15 cm long and 3 cm in diameter and she had a whole Stik in her dish). But wait there is more. She put out the fires with sand, which worked well, but then decided to clean up with wet shop towel igniting the leftover sodium once more.

@@fatman9644 (Changed my earlier comment a bit) You might be able to get sodium to react with sand at very high temperatures, but it does not react under normal conditions. A similar reaction, magnesium and sand, has a big activation energy - you have to get it red hot in an inert or reducing atmosphere to start the process. If you tried the same with sodium it would definitely melt and could possibly boil.

In high-school we were doing a water vapor distillation and were instructed to bring various produce like citrus fruits and such so as to extract their essential oils. My classmates, normies, brought various oranges, grapefruits, tangerines, lavander, and such "vanilla" produce. I brought garlic. The assistant was reluctant but 8am morbid curiosity got the best of him and I was allowed to chop it up and load it in the distiller. The pleasant citrussy aromas were soon buried under the thickest most violent most insulting miasma of concentrated garlic extract dripping into a flask. My eyes were burning a bit and the whole class of 20 people was sniffing and laughing simultaneously. I covered up the output flask because the smell was getting overbearing and people were complaining, but it was more performative than useful. The whole building reeked of garlic the whole day, and other students as well as professors were disgruntedly inquiring who was responsible fot that attack on their sensed amd why were they sniffing. I, an innocent highschooler, was watching the school burn; numb to the stench. The technician who came in with a cold was now cured and his sinuses were as good as ever.

Mines generally use stench based alerts because of noise (and previously due to unreliable signals due to being in an active mine. Apparently (based on some of the MineARC product systems) they even have all clear signals as odorants (wintergreen). You can't hear alarms, but smell isn't drowned out by machinery, plus when you have forced air ventilation the message flows to the whole mine/factory without much effort.

Worked at a local Pb/Zn/Cu mine, and we had compressed gas cylinders of ethyl mercaptan on the intake fans for the fresh air raises, as well as on the headers coming from the compressor house to take compressed air underground. Upon smelling it, and rest assured you WILL smell it, all the workers go to the nearest refuge station and seal the doors. At the time I was working there (early to late 90's), all clear was either to be given over the phone system from the surface or, in the event of an event that cut the lines, by the mine rescue teams (draegermen) visiting each individual refuge station.

When I toured CERN and exited the personnel elevator with my sixth form group I looked up and immediately saw an asphyxiation warning sign and as we were walking there were cabinets of escape rebreathers every 50-100 meters and it dawned on me I'd just entered one enormous array of confined spaces containing an enormous number of active superconducting magnets holding multiple tons of TNT's worth of potential energy that they'd rapidly and violently dump if quenched and tens of tons of liquid helium and other incomprehensibly large amounts of cryogenic gases. It made me sweat a little, but the tour guide distracted me with all the nice neutron probes they had hanging on the walls and there were even more GM counters hanging on the walls, and I must've walked past at least three sample storage cupboards each with a smattering of 1-20 petabecquerel sources (IIRC), and so many posters with math or physics jokes on them.

[@ZE0XE0]

Using odors as signals is an extremely common practice in mines. Fires and cave ins are a huge risk. Radio signals don't work underground and in an emergency one can not rely on wires running along the tunnel carrying phone signals to be functional. Dumping a scent into the mine can usually spread a signal throughout the whole mine in just a few minutes. Most mines do a test of this every month or so in my experience.

[@jonathans175]

I was recently etching some copper with dilute hydrochloric acid that I slowly added 3% hydrogen peroxide into whenever it stopped etching. I'm a hobbyist, so I did this outside in my family's garden since the solution has to form small quantities of (dissolved) chlorine to etch properly, which I just don't want to have inside. Everything went great and there was only the slightest hint of a chlorine-y smell, which was much less intense than even just household bleach, so I figured all was well. At least until a random bug decided that it was a great idea to drown itself in my etching bath. That little pile of nitrogen with wings of course immediately got chlorinated to hell and made the bath absolutely reek like an unhygienic swimming pool. It was terrible, but at least not particularly dangerous. Don't chlorinate insects.

Some 'fun' stories from a kilo lab. In a kilo lab environment, liquid transfers are done almost exclusively by pressure. Either pushed with a pump (diaphragm, peristaltic, ect) or pulled by vacuum. I learned the fun way that when transferring by pump, you need to put hose clamps on all the joints. Once while transferring 45L of some pharmaceutical solubilized in ethanol/H2O, I had a line disconnect and spray me. Thankfully I was wearing a full face respirator and went quickly to the shower. There have also been several times when the bottom outlet valve(BOV) of a 100L clogs following a crystallization. If the material inside is potent (ug levels of occupational exposure or less) that means suiting up in Tyvek or Tychem bunnysuits and climbing underneath there with a screwdriver to take off the BOV and a bucket to catch the product. A fun story that didn't happen to me revolves around being cognizant of exotherms. When my Coworker started, he was running a batch that had a really bad exotherm. It started off at 30C, then started ramping up past the spec of 60C over a span of 10 minutes. For reference it takes the jacket of a factor to heat or cool a batch 30C over an hour. Called up the bench chemist who designed the reaction and asked him what he did when it exothermed for him. "Oh yeah that happens, the product is stable at high temp. I would just toss the round bottom flask into an ice bath". Meanwhile my coworker is standing there like, "there is 40L in that reactor, I can't do that." If I can request one thing of bench chemists, document your temperature changes. Endotherms too are an issue and I've heard stories of stir shafts breaking when the batch suddenly begins to freeze.

There is a similar story often told at our biochemistry department.

So I'm an undergrad doing Mössbauer-spectroscopy, and when I was given the initial tour of the lab as an introduction the head of the nuclear chemistry department pointed out to me that the best working spectrometer has an arm floaty under it because the tram 300m away from the campus causes enough vibration where it messes with the spectrum because it's shaking the oscillating Co-57 source so it's messing with the Doppler effect needed to reliably excite all the Fe-57 nuclei in the sample. Other than that the sample holder is weighed down by a big lead brick precariously balanced on top also because of the vibrations. Also the PC for said spectroscope has been on for 30 years and the analyzer card is semi bricked so half of the software doesn't even work, and nobody dare change it out to the new one that was bought 5 years ago. On an other note the uni has an observatory built on top which is also barely usable because of said tram.

Way back when I was a kid (mid 70's), I decided to make some Chlorine gas in my little garage lab. The experiment went well, and I got a nice flask full of gas and did a few simple tests with it. During clean up, after rinsing my flask with just a little water from a wash bottle, I had the dumb idea to hold it up and look inside through the neck. Of course the flask was still practically full of gas which conveniently poured out into my face while I happened to breath in. Fortunately I had done my research (back then you had to do something like go to a library to learn how to do chemical reactions) and I had some dilute ammonia on hand which I tried to inhale in between coughing my lungs out and crawling around on the floor and ground outside for the next half hour. I was working alone at home after school, and that was scary. My other favorite cautionary tale involves nitric acid and ethanol. Our neighborhood backed up against an industrial park with a little bit of woods in between. Some other kids in the neighborhood had raided an outbuilding that was used for chemical storage - they stole (I was not involved!) gallon jars of all sorts of reagents. Being complete idiots, they then played around randomly mixing stuff. So they filled a test tube about 3cm with pure HNO3, and then started to add ethanol...the test tube blew up, liquids were blown up onto the ceiling and then dripped down onto the participants. Afterwards a little research was done and we discovered that we had inadvertently made hypergolic rocket fuel. Good times.

One more story: my lab partner helped some other student to clean up at the end of the day. He told her to get some acid to neutralize a beaker with some (to my lab partner unknown solution). He did so with half concentrated HCl. As the first splash of acid hit the beaker a loud ‚fomp‘ sound could be heard and my partner stood there drenched in liquid. It turned out the beaker was full of conc. NaOH and H2O2 (still warm from when it was used) the loud fomp sound was the stuff evaporating instantly. My lab partner did the right thing and washed his eyes and then himself immediately after the shock. His safety glasses were milky everywhere the liquid went and he had red spots all over his face for a few weeks. This should be a reminder of two things: 1. safety measures are not to be taken lightly, everything has its use and you can never know when you need protection unexpectedly 2. label your stuff. All of it. Especially if you have someone else using it or working with the same stuff. Loosing your product is the least of your concerns if someone looses his eyesight because of you.

Coming from medicine, sodium hypochlorite is my all time favourite chemical. It's a powerful antiseptic, that does not just kill microbes but actually dissolves their molecules. It also has the sometimes useful property of not penetrating living tissue, so you can use it on wounds and even during surgery on top of live tissue. It also makes the best cleaning agent possible when mixed with regular dishwashing soap, perfect for clean operating rooms.

My solution to deal with the fogging caused by masks is just using non-vented goggles that seal against the face. My university lab had a policy of using those anyway, since glasses do nothing if you're clumsy enough to splash something on your face that is just going to drip down into your eyes from your forehead. (FWIW you can also get glasses that come with an anti-fog coating from the factory and they don't look all murky like trying to DIY a coating) I also have a story I got from my first-semester biology professor about a lab incident: As a grad student, he was conducting a vivisection of a rat that he had anesthetized with diethyl ether. He was undertaking this in a fume hood, but the other side of the hood was also being used by another person who was heating a solution over a burner. You might see where this is going at this point. You wouldn't think the flow from the hood would allow the burner on the other side to ignite the ether fumes (I imagine that was his rationale), but that's exactly what happened. Suddenly, the rat is on fire and is right next to an open bottle of ether. His first instinct is to get the flames away from the bottle, so in a panic he grabs the flaming rat and throws it across the room, where it slides across the floor and into the hallway right as his department head is walking by. From what I could tell, no harm was done except for a significant amount of embarrassment.

When i was 17 studying chemistry, i had to write up a sort of mini-thesis. Long story short, i was heating SnCl2 to dry it during class (this was permitted by my teacher at the time). All of a sudden, a couple students started coughing, as if their throats were irritated. When i had an inkling as to what was going on, and removed the SnCl2 from heat, I noticed both throat and eye irritation. Pretty sure i gassed my classmates. In hindsight, the teacher should not have okayed my suggestion. Edit: this was done out of a fumehood as I was inexperienced and did not read up on potential hazards. I'm doubly surprised that my then-teacher did not anticipate any of this, frankly.

So, back in high school I worked for a pool maintenance service, and many of the pools had automatic chlorinators, basically a piece of pipe you fill with tablets, with a metered flow of water through them. Well one time I open one up to refill it, and it looks like the plastic inside has been stained a deep yellow. I was wrong, the plastic was still white, that was chlorine gas. Felt like I was coughing my lungs up.

I work in radiation detection (scintillator-based detectors) and thought I might be able to relate to or learn from the nuclear stuff, but all our radiation sources are sealed. So our safety training is basically don't eat the sources, don't put them in your pocket or your desk, and don't stick any body parts in the x-ray machine. Now if a source does somehow break... That's intentionally very difficult, and hasn't happened, but my understanding is that you stop everything, call everyone, and you will not be winning employee of the month.

My high school chem lab had a few radioactive samples just to demo the Geiger counter, though we did have a particularly hot sample of Cs-137. I had no idea how old it was, but it was by far the most active one. I demoed it once to a friend and the look of fear on his face was priceless

Hi. Just discovered your channel. Retired nuclear engineer and Certified Professional Health-physicist. The C-14 and tritium stories made me want to cry, they were so over-wrought with radiophobia. Tritium is so harmless that I just don't worry about it. Had that event happened in my lab, my reaction would have been "meh. Wipe up what you can, the rest will dissipate". Tritium emits a beta particle that is so weak that the only practical method to detect is is to mix a liquid scintillator with the unknown and count the light flashes. In the 90s someone suggested that we start looking for tritium in nuclear power plants. When we did we found it everywhere. Tritiated water is made in the core and permeates almost any polymer. After some people spun around like one foot was nailed to the floor for awhile, we acknowledged its harmlessness and forgot about it. C-14 is pretty much in that same class. Now the Cf-252 incident is more interesting. My company owned 10 micrograms which was plenty hot to calibrate our neutron detection instruments. That 10 micrograms cost me a little over $10,000 in the 80s.

Once i had an apparatus implode on me as i was walking in to the lab. The whole room got covered in tiny glass shards, THF and whatever else was in there. Of course i didn´t wear my glasses but luckily i didn´t get anything into my eyes. That day i understood why you should put on your safety glasses BEFORE entering the lab. And you should really take a good look at your glassware before pulling high vacuum.

Always wanted to be a chemist ever since getting my first Gilbert Chemistry set. When I was around 13 a shot train ride to John H Winn Chemical in NYC, allowed me buy any chemical ( concentrated acids, solvents, etc) or lab equipment I wanted, amazed I survived. Winn was the ACE hardware for amateur chemists. Never hand any serious accidents but looking back there was sure a lot of potential. The most toxic stuff a kid could get today would be water, and baking soda. Continued with chemistry through a couple years of college then switched to electronic engineering but still have a love for chemistry.

Great video for sure, liked and subscribed. As a grown up amateur mad child scientist, I have some fun stories. When I was a kid , around 12 or 13 years old, I red in a book or something that sodium reacts violently with water and naturally wanted to make some. I had already done lots of experiments with electrolysis of water and naturally assumed since table salt is sodium chloride I should be able to separate it somehow. My first attempt was to liquefy the salt using a map gas torch and try to use coat hangers in a car battery charger to separate it but the coat hangers kept dripping off and melting into the pool of salt. (Luckily I was unaware how violently molten salt reacts with water or I may have just tried that.) My next attempt was to use the high voltage electricity from a pre-energy star computer monitor, one of the ones that would stay on even though there was no video input. I ran the 25KV arc through a pile of salt and immediately smelled chlorine gas and freaked out realizing... Oh yeah, The other part of the molecule is chlorine.. maybe this is a bad idea 😂😂😂

Reminds me of chemistry classes in highschool. -Our class was a collective dumbass and the teacher wasn't much into safety either, so one student stuck a hose attached to a bottle full of mystery solution, that was apparently fuming ammonia. -Once said teacher made batches of explosive powder that he left to dry in the lab glassware cabinets, next morning coming to several wrecked cabinets and a lab full of glass shrapnel. -One time the teacher made a solution that started fuming like an erupting volcano, spreading a cloud of steam in the ceiling, as the cloud started settling down, it smelled strongly of bitter almonds, so us students vacated the cöassroom in seconds while holding our breaths. -Then there's the time the teacher set fire to some alcohol in non-fireproof glassware, which proceeded to shatter, spreading burning alcohol across the desk, across the floor, over a couple students' backpacks, their notebooks and chemistry books... I don't think anyone in our class learned any chemistry and no one got better than a D-, but those classes gave me a lifelong respect for worksafety regulations.

A technician in my former lab was routinely producing dozens of grams of starting material for various projects. One step was a Staudinger reduction of an alkyl azide with triphenylphosphine. All you have to do is mix both compounds in DCM, basically. So he went on adding the substrate, followed by PPh3, and before he could add the solvent the whole flash went off with a loud "bang". No injury fortunately. The next week a conference person who described the closely related Staudinger ligation did clearly mention that azides and phosphines shoud NEVER be mixed in the dry phase. Too bad this conference was not given a week before.

So I worked in a factory. We did steel parts. It was mostly hydraulic presses, but we also had a heat treat oven. This oven contains a carbon monoxide atmosphere in order to prevent oxidation of the parts as they are heated. Because the system is belt fed, the way the atmosphere is maintained is by continuously creating more carbon monoxide, while the escaping CO burns off as a "flame curtain" at the front. After heating, parts then are dumped into a bath of molten nitrogen/potassium chloride at anywhere from 400 to 650 degrees. Occasionally the quench tank must be drained for maintenance work. However, the tank cannot be completely drained by the pumps, so the final cleaning is done by hand with water dissolving the now hardened salts. A coworker got sprayed with extremely concentrated water. He also got a face full of the stuff. He didn't suffer any permanent issues, but the clothes he was wearing were kept on display at work for a while because they were so full of salt that they stood on their own. As a bonus, the fire department requires them to keep working sprinklers near this tank of molten salts... If anything were to try the sprinklers near that thing while there's liquid salts in that tank, you've got a very large hydrogen generator right next to a giant oven kept at 1600, and a CO generator putting out something like 700cfh of CO...

Radiochemistry is a lot less hazardous than people think. What other hazardous chemical can you detect and localise immediately with incredible sensitivity inside a sealed opaque container? People working with regular genotoxic stuff like ethidium bromide end up tracking it all over their labs, cars and homes without knowing it.

My Radiological Disaster story came from the 1970's. The US Navy finally realized that "glow-in-the-dark" radium dials just MIGHT be unsafe! (Maybe...) Anyway, the orders came down to survey any dial faces/control panels/clocks, etc., and properly dispose of any radioluminescent dials. One such clock face found was the personal property of a senior officer, and he did not want to lose his favorite clock. So, he gave the clock to a Recruit, and told him to scrape the radium paint off the clock. Said recruit did, right on a table in the ships galley! Said ship went into the yards for 8 months for decontamination. The High Ranking Officer was assigned a desk, not in his ship, and left there until he retired (about 5 years early...) Mind you, the Senior Officer was a Naval Academy graduate and had served on nuclear subs, and STILL pulled this boneheaded move. A major Charlis Foxtrot to say the least.

I've got a few radiation related stories thanks to my family. This one might not be that chemistry-related, but I think it's still worth sharing: My great-grandmother worked at Rocky Flats back in its heyday. She was one of the first women engineers to work there... unfortunately that had some bad safety implications for her. She was a small and petite woman, so the respirators that they had (all sized for men) didn't fit on her face properly, and let some (contaminated) air in around the sides. On top of that, her coworkers weren't the most respectful of women. Because she was a woman and small, they made her CRAWL UNDER THE GLOVE BOXES TO CLEAN UNDER THEM. (For anyone who doesn't know, the glove boxes are where workers would use tools to shape the radioactive plutonium pits. They were enclosed and had gloves built-in so that workers could reach inside safely. Unfortunately, they often weren't sealed all that well, and plutonium dust could escape and settle on the surroundings.) And, on top of THAT, after one of the fires, (I don't know if it was the 1957 fire or the 1969 one) her DESK became contaminated. She worked at that radioactive desk for a year (might have been two years actually) before anyone realized it was hot. I didn't hear this story directly from her, as she died (of plutonium-related illnesses) when I was little. My grandmother told me all about her mother's (and her father's, her sister's, and her own) experiences of working at Rocky Flats. As Grandma put it, "She loved her job, and it killed her." I think an important safety lesson to learn from this is that lax safety culture isn't the only dangerous workplace attitude. A culture of disrespect toward some groups (whether it's over gender, race, language, or anything else) can cause just as much harm.

Very few of them have anything at all to do with their political leanings.

Spray some onto the inside surface of your goggles, ensuring to wet the entire surface with the liquid. Do not wipe it off, just let the liquid evaporate, so it leaves a thin coating of whatever the residue is in the spray. I don't know what this residue is or why it has the anti-fogging effect, but I promise it works.

They use a shielded bag about 20+ kg to carry the isotope around and the box has a tube that can move the isotope out of the box to shoot the picture. Here's the fun part, most of the operators cannon even read or write the local language and for get about English or other language and we engineers have to "write" all of their papers including the exam and even their work contract information. Once they diagnosed to be received too much radioactive, they will be resigned and return home that usually after about 1-2 years. They shoot these photos all around the country too, loaded the isotope in a truck and drive around the city. I quit that job after a month.

He didn‘t tell me exactly what he was working on and I honestly don‘t know if he even knows but he had to pipette some concentrated lye. For some reason there wasn‘t any of those plastic suction things available so he decided it‘d be a good idea to use his mouth to pipette the solution. I personally had never heard of this being a practice but when you‘re in a pinch, ig. Now you won‘t be surprised if I tell you that he sucked just a little too hard and ended up having concentrated lye in his mouth. He immediately realized his mistake and flushed his mouth, which was being turned into soap, with as much water as possible.

Its a year late, but from a welder, the dilute soap solution works really good to stop fogging. What you do is put dilute soap (foaming soap works too, its prediluted) on a cloth, wipe the goggles down thoroughly, then wipe them once with a dry section of the cloth to clean off the worst of it. It is _slightly_ worse than brand new goggles, but it keeps them from fogginv for awhile, and the slight haze is way better than foggy goggles.. When I was doing oxyacetylene welding I had to reapply it between once a day and once a week, and that was for 8 hour days.

[@enkilakasha]

to prevent fogging, use a regular bar soap, rub a cloth rag on the soap then proceed to "polish" the safety glasses with it. it will create a film on which water is unable to condensate on. works wonders for my glasses.

I live in the south of Spain, where it gets pretty hot around summer. In the lab, there are DCM wash bottles, and they have the tendency of building just enough pressure that when you touch it even the slightest, they squirt out solvent for a few seconds. Well, before I had this in mind while in the lab, I was doing an extraction, and when I went to grab some DCM, it shot right into my eye (I happened to not be wearing eye protection). Quickly went to the sink and washed it, and nothing happened. That same day, another girl also got DCM in her eye, and someone said it's not a very weird occurrence, that many people in the lab have had it happen at least once.
