When I was in the military, we all had a very...cavalier attitude towards PPE. We were always told to wear it, but didn't when no one was watching. One time, I was servicing the lubricating oil in a turbine-compressor on an aircraft (basically a giant turbocharger that compresses air to be forced into a condenser to create a rapid cooling effect), and while standing directly below it while looking up, a drop of the oil fell DIRECTLY into my eye. I flinched and blinked a couple times, but couldn't get it to clear. My vision was blurry because of the oil coating my eye, and I started to get scared. Then, I remembered that we had an eye wash station like you highlighted in this video, so then I ran to it and flushed out my eyes. I turned out ok, but it was really scary. WEAR YOUR DAMN PPE

One thing to really note, even seemingly safe and simple labs can get dangerous if people fuck around. I still remember the large scale emergency response to the "Hauptschule" next to my elementary school here in Germany during my childhood. I later in life looked up what actually happened, and some of the pupils there took some random chemicles during chemie class and mixed them together for shits and giggles to see what happened. Idiots brewed up litteral flammable poison gass, and blew up the lab while poisoning themseves and a few others. So always do things with proper procedure and maybe keep an eye on what others are doing around you. I have heared multiple stories from people working with chemicals, in which it was others endangering everyone in the lab because they did not follow proper procedure and fucked around. So keep an eye out when working with others in the same lab.

I've personally nearly permanently damaged my eyes when I was about 15 and was curious what batteries looked like on the inside. I did not wear goggles. I was using tools like needle nose pliers from out garage and for whatever unknown reason the battery exploded. the electrode shot up and collided with my eye faster than i could blink. I was close to the shower and thankfully I knew to rinse out my eyes. I wasted no time to get undressed or anything i just turned the shower to full, got in and rinsed my eyes. They burned horrible bad and i was screaming in pain. I had flashbacks for about a year afterwards. the doctors at the ER told me that I was lucky and the ocular specialist told me that I had sustained minor burns around my eye socket and I had a small indent from the electrode hitting my eye luckily it missed my pupil by a few millimetres. All that to say that I have always been extremely cautious ever since.

For some reason we'd gotten an alkaline battery once, which had each cell in a sturdy steel can instead of plastic, tar and corroded zinc. The cell had a tiny vent hole in the top plastic ring, which appeared to be the only weak point. I hammered an awl into it, and pressurized liquid squirted out. I was lucky that it missed me entirely.

Considering the amount of dangerous chemistry thrown around on KZbin with zero safety advice, this sort of video is absolutely beneficial. Pretty thorough and well made too, as always. I got my only chemical burn ever in highschool chemistry class, and it was wholly due to incompetency on the teacher and school part. The teacher was having us come to her desk all at once in complete disorder, to collect a few mLs of 6 mol/L HCl in our test tubes. She had already made us use chloroform in an unventilated room to speed up chromatography, so it was not surprising that she deemed this *safer* than having the lab tech place them in our racks along with the other tubes. As I was coming back to my own desk with my filled up open test tube (they didn't provide stoppers), Murphy law's struck ; I was bumped into by another student and the contents of my test tube splashed out onto my right wrist. Now, with proper size gloves that would have been okay, but we were only provided M and S sizes, and I already needed XL back then. Thus, the splash landed right onto the edge of the glove, quickly drawing the acid inside by capillarity. It only took a few moments for me to safely store away the tube, take off my glove and start rinsing, but I still got a painful burn that left a few cm² of my skin suspiciously smooth for a couple years. My former chemist of a dad was astonished and furious when he heard of that event. I've been an absolute stickler about chemical safety ever since!

[@rangeldino2633]

How long did it take to wash your hands? I've had HCl on my hands quite often, and it never really hurt, neither 10% nor 30%, although even 30% was on my skin sometimes quite long... Like a minute. Tbh when I knew it won't hurt I may was also a little slower sometimes with washing it off in order to make some contacts or so. The first time I got that acid on my skin I thought it would hurt, so I was a little bit to fast on the way to the sink and felt, realizing that it wasn't hurting at all. Guess the smoothness comes from the acid turning off a bit of the dead layer of the skin. Or just the sebum layer.

[@_tyrannus]

@@rangeldino2633 It took me a few seconds to realize that the moistness was HCl and I did not feel the burn immediately, but I must have had it on my skin for 10 to 20 seconds while I made my way across the classroom full of other HCl-carrying students, set the tube down on the tube stand, pulled the tight glove off my hand and started washing it off. I don't recall any percentage, just the 6 mol/L concentration of it which was much higher than what we should have been working with by the rules.

[@rangeldino2633]

@@_tyrannus Ah ok. Then you can definitely calm down, because after that time your living skin was not harmed yet. Maybe the dead layer of the skin was slightly damaged, leading to this smoothness (But I would not recommend to do this regularly, because ofc this layer is a natural protection against corrosive stuff). Btw I found some hours ago an old video of NileRed where he puts his hands into acids like HCL, H2SO4 and nitric acid ^^ Video name is "Pouring different acids on my hand" You are right, in school one should not work with that stuff without proper safety and safety instructions, also because a student may not think about it and rubs his eye in a second or so. But on the other hand I have to admit I would've been glad if my chemistry lessions in school would've been less theoretical.

[@_tyrannus]

@@rangeldino2633 I've definitely had worse burns and gashes, a pointy rock can obviously do worse things in less time to your skin than any acid. Nevertheless, in terms of how fast it got painful, it beats any lye/battery acid/acetone/concentrated bleach that I've accidentally gotten onto my skin otherwise. On the plus side, it was quick to wash out and didn't penetrate the skin too deep. As a side note, that same teacher later on thought that the usual cyclohexane we were to use for chromatography practice was too slow, thus she mixed in a bunch of chloroform. Each student group used it at their workstations, without any fume hood or room ventilation beyond a single open window in the teacher's corner. She didn't want the hallway door open, of course. -_- Several students felt dizzy afterwards, and my former chemist of a dad was not amused.

[@theexchipmunk]

Yeah, overcofidence is extreamly dangerous. I might not work with chemicals, but I worked as a lathe operator in the small run, large piece manufactroing where we produced large to very large elements for various specialty industries. I have worked on a the massive casings for a chip production line for Nasa, the turbine shafts for chinese waterpower plants, u-boat parts like massive titanium hatches and a lot of other very cool and special stuff. And one thing is always important. A lot of conectration and to never get too comfortable. Some of the lathes I worked with had the size of a small house, with a horizontal chuck the size of a carussel on a fair, or a working space thats 2 metres deep and 12 long. And those machines I had to climb and walk in to set up, replace tools, repair and controll the workpieces. I the only way to actually move stuff around was one or even two ceeling cranes, and weights of less then 100 kilogram were a rarety with machine parts and work pieces if it wasnt bolts. Most of the time stuff was in a ton range of weight. And depending on it multi ton work pieces would rotate at hundreds of revolutions per minute, with speeds a raching car would drive and tool pressures applied to the side that was in the multi ton range to. If you did your job right, it was pretty safe. But woe you if you messed something up, forgot something, miscalculated or were unattetive. Because with the weigts and forces involved, if something goes wrong, it really goes wrong. To those machines a human is basically what a fly is to a human. The dont even notice an arm or a leg getting in. And human strength is absloutely laugthable and does not even register. I had a few close calles during my time working with that stuff. One morememorable was me on a bad day forgetting to do the final tightening on the holding bolts for some very heavy spacers slottet into the chuck while turning a turbine shaft. Overall just head sized chunks of solid steel. When I started the machine it spun up to 1800 rp/m and after a few seconds on max speed the things came loose. They shot up straight through the enclosure, up to and hitting the roof of the workshop at 15 meters, and came straigt down around me. Two impactes in around a 1 meter radious around me, and one came by my ear and slightly "brusched" my upper arm. Still enough to rip open my work clothes and I still got the scars from that brush with death. Because those things left craters in the solid concrete floor. If it had come down just a ferw centimeters off, it would have hit me straight in the head, pulverised my skull and probably folded my backbone like an acordeon. Suffice to say I left early that day and had a few too many beers in the evening. Other events include a college just brusching a spinning chuck and having his hand instantly shattered and ripped upen, or another crushing his leg because he was in the machine setting it up and coming against the tool control, getting it between the wok piece and the tool carrier. Thankfully I have never seen somone die, but we were shown very gorey footage of what happens if you really fuck up during work saftey schooling and refeshers. The most notable is why you never ever wear long sleves. That one will stay with me for the rest of my life. The dude in the video got his long sleeve caught in a spinning work piece on a lathe. Got turned into the most gruesome slinky known to man and that whole shop needed a crime scene cleaner because of the spray. Worst part was that the dude didn´t even get pulled in intatly, but managed to hold on for a few seconds. That one ugly way to go, and really drives home how powerful these machines are. If you get lax or fuck around, you won`t find out, because you won´t have enougth time left to think about how dumb it was in many cases.

[@Oberon4278]

​@@theexchipmunk I really enjoy machining videos and your job sounds so cool. What kind of tolerances did you usually work with? When you had to center on a four jaw, how did you set up the indicator and how much travel did it have? I'm used to looking at tenths on a tiny little thing I can move with my finger.

[@theexchipmunk]

@@Oberon4278 Well, regarding the tollerances it really depnded on the piece. When we made the castorcontainer for an experimental reactor it was nearly all in the millimeter or tens of millimeter range, except for the seal area at the lid. But with stuff like the turbine shafts that would for years rotate at thousands and with the "smaller" ones tens of thousands of rpm? The overall roundness and straigntness was in the hundreds of millimetres for a 2-5 meter long part with a diameter of about 20-40 centimeters, some of the fittings for the bearings were in the thousands of milimetres. Every small inconsitancy could massively shorten the lifeexpectancy of the part due to the very harsh loads and speeds they would be subjected too. When centering and not just using a freshly overturned tip on both ends (one driven the other on a bearing) because it was easier to achive the high requirements for roundness that way, I would generally fix my indicator on the machine bases rails that the tool carrier traveled along on. The best place because it´s the most solid and flat area without any possibility for it shifting. Then I would use the arm the indicator was fixed too, to get the tip of it as close to the jaws as possible on the workpiece to get it as accurate as possible. We usually had two indicators, depening on accuracy only the first with 10 mm overall travel and 1/100 mm accuracy was used and if it needed to be in the 1/1000 we all shared the second to get it really finely set up. ( and if you broke that one you would be the but of a lot of jokes and get a talking to, thing was really expensive) But that was extreamly rare, because we generally planned the process in a way that the parts that all needed such a degree of accuracy would be turned in one operation, so we would not need to do that whole very involved setup. As the saying goes, work smarter, not harder. Especially when time is monery.

3:18 This part everyone, especially Chemistry students or new and inexperienced Chemists, should take note of.

One managed to finish first and took off her lab coat and goggles, the other one was conducting a test for Ammonium ions through release of Ammonia gas from a reaction. The reaction required the reactants to be heated and the girl had put the reaction vessel (a test tube) directly into a Bunsen burner flame and the test tube exploded, the girl without goggles got some of the reactants (dilute Ammonium Chloride and dilute Sodium Hydroxide) in her eye and had to go to a Nurse, she returned a few minutes later and she was fine. This was an accident but if dilute Nitric acid was used (for the Carbonate test) she would have had her eyes burnt out or at least severely damaged.

When I was in chemistry in high school many many decades ago, a girl in my class had a unusual hairdo with a large teardrop shape of hair in front of her head. This of course was held in place by lots of hairspray or some sort of hair product. We were using brinson burners. She leaned over the burner to do something and a second later our teacher was a very tall man looks up sniffing his eyes focus on her and he starts vaulting lab tables and then starts smacking her on the head with some papers. Of course we all thought he had lost his mind until he pulled the papers away and that teardrop of hair had burned away. After that anyone with hairspray, hair gel, mousse, or anything else in their hair was required to wear hair covering like a surgeon would wear while in the lab.

[@_tyrannus]

Lol my chem teacher was super chill. So when he got mad it was genuinely frightening. Like even if he wasn't mad at you you still felt afraid 😂. But one time we were doing a lab which primarily consisted of acids, bases, and ionic compounds and metals. And demonstrating different properties of different types of reactions. Two dumbasses decided they weren't going to do the lab so instead they were going to play catch with a baseball from opposite ends of the room. Needless to say my teacher was furious and promptly told them to leave 😅

One time in my school the chemistry class was doing...something (I can't remember what, this was a long time ago). A girl spilled a ton of the chemical on her pants and it immediately started eating through her jeans. The professor tackled her, ripped her jeans off, and dragged her into the safety shower in seconds. She got away with very minor burns, but her jeans were toast. I feel like she should have been wearing a lab coat if they had been dealing with something that dangerous.

[@ivanmeneses925]

In my college, about 5 years ago on an entry level chemistry lab there was a demonstration about metallic sodium and potassium and water. When the metal was dropped into the water, the assistant's coat caught fire and she freaked out, spilling the metal in to the floor. She then ran to the emergency shower, right next to the spill, to extinguish the fire in her coat. Hilarity ensued when the sodium (or potassium, can't remember) in the ground all reacted with the water from the shower. They had to evacuate the whole lab, she doesn't work there anymore :(

[@Superbug-tf8zy]

She had the good reaction to go in the shower, But sadly that doesn't always fix a problem.

[@TheDeathmail]

That shouldn't have been blamed on her. Human reaction can't always be controlled.

[@marthajones9284]

But when working with those metals its important to only cut off small pieces that don't do much damage even when they reaction is out of control. So there should not have been a large enough piece on the floor to make them have to evacuate.

[@Rime_in_Retrograde]

I'm grateful that the ChemE department at my university takes safety seriously. Before we even begin an experiment we have to write up an experiment safety plan- basically they cover everything in this video: steps of the experiment, ppe, what can go wrong/what to do about it, and other safety protocols. Honestly, even though they're a pain, I can't imagine just *doing chemistry stuff* without one, and I'm glad people are bringing safety awareness to anyone who might want to attempt this stuff at home.

[@Rime_in_Retrograde]

This video was still better than any sort of science safety training we did in school, I think because it includes real-life examples of what can go wrong in a lab and thereby demonstrating why XYZ precaution is necessary. E.g. high school chem teachers would say "Always wear safety goggles in the lab to protect your eyes", and then you don't take it seriously because you don't know of all the ways substances can splash up into them or what the chemicals can actually do.

4:12 so THAT’S what those faucets were for! I never knew, when I saw them in teachers’ chemistry labs. Also, thank you for covering these safety things, that are intricate for proper lab work, and can even save lives. I have a friend who works in these labs as a teacher’s assistant, and this one friend was helping a student with an experiment involving some acids or another. Another student got it on her face, and on her arm, where she had a HUGE open wound (she had bandages on, but these bandages actually soaked up the stuff, which made it worse). Luckily, she was cleaned up quickly, and the acids didn’t severely burn her face, but her arm was pretty fecked. The reason why her arm was exposed? She had rolled up the sleeves to accommodate her thick bandages, and taken off the glove on that arm to make it easier for her to work with her bandages and take notes. The professor had a panic attack after class, because if they hadn’t gotten the bandages off fast enough , it could’ve really hurt her, especially since she had an open wound, and such a large one, and it could’ve even killed her because it could’ve eaten through some veins, or made her super vulnerable to infection or something (I don’t remember exactly, this was something my friend experienced, so the details aren’t super clear). Yeah… that Professor was super scared for her. Luckily, the girl was fine, and she actually went out after class, and got her own super solid lab coat, that had loosening strings so she could wear her proper brace (I dunno why she didn’t just opt out of the experiment, but my friend said something about deadlines or something?). She actually still has it, I follow her IG and she still wears it when doing her work (she likes to share some of the results of her assignments, since her major is in chemistry, I follow her for her art too, she’s very smart and talented). She even got a baby one for her kid, so when he and her do mommy and son experiments, he’s safe (even though the scariest thing they’ve done is do an elephant toothpaste experiment, and they even had a rig so they could do it from a distance). So yeah, if y’all are gonna do chemistry, even as a hobby, please be safe and careful. It’s just better to be safe rather than harmed.

Hey. Just wanted to mention that your video here potentially saved my life from Nitric acid. Watched this, and knew of course there are many precautions with chemicals to take. As an ex automotive student, and step son to an automotive fanatic I am familiar with organics, and nasty particles somewhat, so I knew some drills. Long story short your video really made me 10x think about anything I was about to do. This came in handy when I had 10 LITERS OF NITRIC 70%. I assumed that If I can filter chlorine, and even mercury vapors with masks NOX shouldn't be any different......I did some more research to be sure, and got slammed with reality that I had some dangerous potential sitting in my home lmao. I looked up; "what respirator to use for nitric dioxide" Google; A firefighting suit, with closed system with air tanks. Woah, and YIKES. So, thanks for this video. I now dig as far, and wide as I can before fooling around with anything. If you get the chance I am curious about what a fume hood does with NOX gas, and what you would suggest using for similar things. Always glad to watch what your up to, and your videography plus humor mixed with seriousness are a perfect balance.

One part of my sister in law’s job is small-scale explosives manufacture. She is the lead chemist and safety officer at the company, she knows what the hell she’s doing, and last year she still had several grams of product detonate in her fume hood while she was working with it. Thanks to blast shields, safety protocols, not working alone, and a decent bit of luck, all she got was a bunch of glass shrapnel in her arms. Lab safety is serious. Even if you absolutely know what you’re doing, you have to assume every day that Murphy’s law is gonna get you.
