I 100% agree. But you never feel more alive than when you are trying to make and contain chlorine gas in a bootleg lab. We always used PPE but had no real lab space. Those were the days.
"Yeah, I don't want to do this. A group of terrorists could just come running in with AK-47s and shoot at all the precious lab equipment that I have, and then a nuclear missile would come towards me in minutes. Too dangerous, I'll pass." /s
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
When I was in boot camp, we were instructed to clean the bathroom with just a bottle of bleach, a sponge and a bucket. No PPE, nothing. Within the first 10 minutes, a guy had splashed bleach in his face. His right eye fucked up for a while but he turned out okay. Moral of the story: military fucking sucks and I left
My father always told me "Son, there are accidents, and then there is carelessness. Carelessness is putting yourself in a position to have an accident."
A friend of mine was doing everything right. Solid A+ uni chem student. Someone else mislabeled one of the chemicals he was working with, and he ended up with permanent scarring on his face when combining that mislabeled chemical. Even the most trained, methodical chemist can end up in danger.
The simple idea of having a mislabled chemical is a huge "gtfo" for whoever did it. Especially in stuff like aerospace, imagine messing up a hypergolic fuel mixture that uses hydrazine or something of that style. Instant explosion or corrosive/gas.
i hope the person who mislabeled it got in major problems and pays for all medical bills from the scarred person and than some more issues too even if it was a accident, those accidents should not be forgiven for their lethallity
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.

Me and my colleagues were taught that working with gloves was not necessary and borderline dangerous, maybe because most times we were in the chemistry lab we had 400mL of fuming nitric acid very close
Also: Another PPE for people with long hair is to have a hair tie or hair net, I don't know how often I've been millimeters away from catching my hair on fire.
I have become familiar with the smell of burning hair before I finally started being more careful. My hair has never caught fire but it really should have
And for those who only have hair ties as their option, always put your hair into a bun (not a ponytail) that way it’s very unlikely to get caught in something. I always wondered why my high school AP bio teacher told me to tie my hair into a bun instead of a ponytail, but after hearing disastrous stories in college, I finally knew why that was the case
@@povgfuelgaming7521 my mans really said that and then gone and stunk up the entire street and then cooked it with a blowtorch and stunk up a holiday retreat for good measure
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.
Nasty, glad you're ok. As a kid, I used to disassemble used up 4.5V zinc carbon batteries for the carbon rods, to use for carbon arcs and electrolysis. 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.
I had a friend as a kid who had a glass eye, apparently they'd poked it with a pair of scissors. So glad I have good eyesight, not something I take for granted. Gotta take care of these peepers :^) Glad it didn't go worse for ya.
I've been thinking for a long time about making a video about the difference between real danger and perceived danger. It's often easier to see the danger in flashy and fiery TH-cam videos, while being careless with mundane (but statistically extremely dangerous) things like ladders and razor blades. I think an accurate perception of real danger is one of the most critical steps for safety in all activities.
I think this is because we use ladders and razor blades in our everyday life so we have the feel of fake safety and dont care. Flashes, arcs and tesla coils are something special so we are aware because we never seen something like this before and are aware.
@@milanhlavacek6730 well in chemistry some of the most dangerous thinks are the invisible vapors of some toxick substances and even some visible ones can be realy fast to end a carless persons life
@@theclockmaker633 yeah high voltage is kind of same - you cant see it but it is lethal. A lot of stuff outside of human perception is quite dangerous for humans as there is no way to know its presence without special instruments. I myself do not do much chemistry but safety is needed everywhere.

@@JohnnyYeTaecanUktena a lot actually. A friend of mine who was interning as a teaching assistant had her prof show this to the class and this was shown, albeit briefly, in a HSE corporate video I had for my company.
In the lab I used to work at, our "safety" guy was a schlub and didn't regularly flush our eye wash station. Since it didn't get used for years when it finally was pointed out in an audit, we turned it on and it was just a 10 second stream of black sludge. It was hilarious and terrifying in a 1:1 ratio.
When i was in middle school i was in science research and the eyewash and shower had to be replaced mostly because rust would always come out. Also the fume hood didnt work. Luckily there were 2
That'd be black rust, Fe3O4, from the water pipes. Imagine if the poor guy who needed to use it had oxidizer in his eyes... "local chemist burns eye sockets out with thermite".
The weird thing is that I never realized so many of these safety precautions are used across all industries. I work in healthcare and have to follow the same fundamentals.
Funnily enough, a lot of safety procedures are just common sense, but of course things like being careful with uses gloves can be a bit tricky if you're not careful or not used to taking gloves off and on
honestly I wish more industries shared more concern for material safety. I work for one of the largest shipping companies in the world, yet hardly any attention is given to proper hazmat training. Its pretty unsettling to learn that you have a dangerous hazmat on a truck only when people start getting burned through cloths, and then to find out that we didn't even have the MSDS for the chemical on file.
There's a famous series of articles from back on the old web called, "Things I don't Work With", by Derek Lowe. Wherein he describes the horrors of journals describing things such as FOOF, Hexanitrohexaazaisowurtzitane or Chlorine azide. People had to work with these, someone ordered them to do it, and they suffered. And sometimes, you'd get things like carbon tetrachloride; which made it into consumer products that you or I could have been exposed to because someone didn't think that in-home halon was bad enough. I suggest you read though these, as they're a harrowing ride though many obscure _and purposefully so_ chemicals.
@@ChrisSpecker Pippetes are goddamn anti-personnel fences. You drop one and then there is a glass on the floor for the next ten years, no matter how hard you try to clean it.
@@Folemaet The solution to that is easy, just get enough HF to coat the floor with a thin layer and intentionally spill it on the floor. Problem solved!
Love the video. One small note. You showed your eye wash station, and you took the caps off before turning it on. Viewers should know NOT TO DO THIS IF YOU HAVE AN EMERGENCY. Proper eye wash stations are designed to pop the caps off automatically from the water pressure, saving you precious seconds that can make a big difference. Especially when you're blinded/have your eyes closed, it could cost you a lot of time trying to get the caps off. Edit: a word
The part about no food and drink reminds me of my favourite chemistry rhyme: "Johnny was a chemist A chemist he's no more What he though was H2O was H2SO4"
See also: Two chemists walk into a bar. One of them said "I'll have a glass of H20" The other one said "I'll have a glass of H20 too" The second chemist died.
Good Video, I am a chemistry professor in Wisconsin and i always try to teach my student and scholars about safety and they never listen! after last year's incident (A 16 year old kid accidently swallowed Sulfuric Acid and was rushed to the hospital!) the school principal was trying to find a educational video about LAB SAFETY to show to all the students and then we found this video! almost all of the students knew who you are and loved your channel so they listened to you and it worked! Thank you for this great video. P.S: THE KID IS OKAY!
Guess so, we were extracting hydrogen from glucose when the kid wanted to take a sip of his water and confused his water bottle for the sulfuric acid container that was on his table 🤣🤣🤣🤪🤪, luckily he is okay now @@Giblet12
The worst enemy is overconfidence. A colleague (laboratory technician) of mine has died of fluoric acid. Working with the acid was actually routine for us. Until he wasn't paying attention and the broth spilled over his hand because of delayed boiling.
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.
@@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.
@@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.
After 4 years studying biocheistry at a state colleague, I can say I was taught only 5% to what Nile covered in the video. Basically the colleague did not bother to protect its students.
As a former uni lab tech we called it glove stupid, "I have gloves on so I am safe" they then touch their face, phone, door etc. Awareness is the key. Also sitting down in chemistry labs is a recipe for landing a lap full of bad times.
Classic risk compensation. It's like how people drive faster wearing seatbelts. There's the thought experiment that says installing a big spike in the center of the steering wheel would make people drive more carefully.
Ugh I needed to go to a store the other day and the cashiers had started wearing gloves... and that was it. They weren't changing them between customers, and were still touching everything they normally would, and thus were only possibly barely protecting themselves *if* they remembered not to touch their faces or clothes until they safely take the gloves off. It just seemed borderline pointless given the risk of it adding a false sense of security, because I know it would be impractical to change gloves every single time they check out a new customer. They might as well just wash their hands or figure out a hand free way. That said I treat all my grocery bags as dirty, and sanitized everything I bought myself too.

Considering the amount of dangerous chemistry thrown around on TH-cam 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!
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.
@@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.
@@_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.
@@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.
As an electro-mechanical engineer, it's always fun and interesting to see how the other disciplines take safety into account. I don't deal with too much more than high heat and fast objects, but you never know when some experiment will have a chemical situation.
Jesus died for us all, and rose from the grave to defeat death, so we can have eternal life. please give your lives to him, and repent, he loves you!🙏🙏❤️
Safety in engineering is no joke either. People tend to get comfortable when they work around heavy machinery a lot. In such cases, a quick peek at the definition of degloving usually helps, an image definitely does.
Another thing to consider for anyone working in a lab or even building up their own: KNOW WHERE EVERYTHING IS!!!! If you need to get to the eyewash station without being able to see, knowing roughly where it is is gonna be crucial
I wish my chemistry teacher used this video. At the beginning of the year we had to study these things and be tested on it. This was actually really entertaining and enjoyable to watch
@@Jeyserhatesyou bruh, organic is easier than inorganic? Maybe not practically but in theory, right? I mean it is mostly just remembering stuff, although there are a lot of exceptions.
Here's a free safety tip: If you're heating something horrible on a burner, don't forget about it. Everyone else in the lab will be really angry when you poison them. Also, if you're working with UV, don't leave the light on all day. The sunburn is going to be funny looking. And if you spill radioactive powder all over yourself and the floor, don't just run home, leaving it for someone else to deal with. Your coworkers WILL use the Geiger counter to track your radioactive footprints to your assigned parking space.

I nearly lost both my eyes in a lab accident and my goggles barely saved them. Nearly lost them again in the field handling a chemical pump but my glasses saved me. You cannot stress enough how important eye safety is.
On the PPE section, specifically gloves, even professionals make mistakes. I can't remember the exact details, but there was a case that this researcher working in (I believe) an MIT lab was dealing with an organic mercury compound and had been using Nitrole gloves; well it turns out the gloves are permiable to the compound. The researcher had just a drop fall on the gloves and thought nothing of it, she didn't immediately change them and went home later as usual. She absorbed an incredible amount of mercury from that drop and it shriveled up her brain like a raisin. I can't remember if she survived long term, but in the short term she had permanent brain damage. So those points about checking compatibility and changing gloves if they become contaminated are very important indeed.
I know what you are talking about and that woman died in 1997. At the time they thought those gloves worked for organic mercury and her accident revolutionized PPE around organic mercury specifically, but extensive testing across the board was also done due to that incident as well. She was wearing 3 sets of gloves and also did take them off immediately, but the chemical still made it through. The specific type she was exposed to was lipid soluble (fat soluble) and got stuck in fat cells in her hand. As those cells broke down normally she got microdoses floating in her blood. Over time these micro-doses brought the mercury to her brain and CNS and caused progressive neuro degeneration until she died roughly a year after the accident. She was a world famous researching covering heavy metals and their effects on humans and when she figured out what was happening and that she was likely going to die she called her colleagues from around the world and told them to use her as a case study. As a result her death, while horrible and slow, is one of the best documented case studies ever made about chemical toxicity since the discovery of the extensive human testing documentation at the end of WW2. She went deaf, blind, lost faculties and reasoning over time, and eventually could not even walk or speak at all. Eventually she entered a vegetative like state, but it was noted that sometimes she made expressions and noises that sounded like she was trying to scream. Eventually the nuero degeneration was too severe and she died as a result of acute mercury poisoning. This was even after months of treatment with a medicine that allowed helped the kidneys pull mercury out of the blood. A large consensus as to why she still died is that the medicine is not effective at removing mercury that is already bound to fat cells and the CNS is almost entirely composed out of fats. ChubbyEmu has a narrated TLDR'd version of the case study and story if you are interested.
Her name was Dr. Karen Wetterhahn, a professor of chemisty at Dartmouth college. She was exposed to dimethlymercury in August 1996 and died from the exposure in June of 1997.
NileBlue: Safety is something that I have always taken seriously. NileRed: I like to mess around with dangerous explosive carcinogens that look like blood because its fun.
Your warning about goggles in the lab is an important one. My father was blind most of his life from the 1950s til he died due to an accident in the lab (a medical lab he worked at at the time) caused by a coworker. He never saw what me or my younger brother, nor my mother looked like when he was alive because he was completely blinded due to the chemical burns.
He's normally a bit monotone, but today he was very firm and passionate about the information he presented. I could hear the urgency in his voice! Take the man seriously
The most overlooked safety rule in chemistry is "don't leave anything between you and the emergency hood vent override, window, door, fire-alarm and 5 mile distance"
I'd add onto this: If you see a man in a lab coat running, you also run. I have seen (and been in) several fires because a reaction went out of control and ended up causing a fire that detonated (yes, boom) the lab gas pipes. if a lab is on fire, GET OUT then call the fire department.
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 😅
Im a chemist myself, and i work with HF. And let me tell you, that makes me always scared to use. The worse i had was Conc sulfuric Acid being spilled on my hand. Hurt like hell, but no permante damage.
3:18 This part everyone, especially Chemistry students or new and inexperienced Chemists, should take note of. As an A level Chemistry student I observed the need to keep PPE on even when you're done with your practical as others might still be working; there were these two girls that were finishing off their Qualitative Analysis of Ions practical. 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. Wear your lab coats, chemically resistant gloves and goggles!
The only time we needed safety goggles in my freshman bio class was because we were messing with acids. One kid took hers off "because they're uncomfortable" Guess who got her eyes washed!!! Bravo, Delilah
Hey there, Delilah You’re cloudy blue eye looks so pretty Its a thousand days today But, a touch of wind’ll make it misty Close your eyes You do it about half the time I said no lies Oh, it’s uncomfortable to see Oh, it’s uncomfortable to see Oh, it’s uncomfortable to see Oh, it’s uncomfortable to see It’s uncomfortable to me
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 :(
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.
It may have been helpful to mention Karen Wetterhahn's case when talking about the gloves. Karen Elizabeth Wetterhahn was an American professor of chemistry at Dartmouth College, New Hampshire who specialized in toxic metal exposure. She died of mercury poisoning at the age of 48 due to accidental exposure to the organic mercury compound dimethylmercury. her latex glove offered no protection, as the 2 drops of dimethylmercury passed through the glove and into her skin in under 15 seconds. -en.wikipedia.org/wiki/Karen_Wetterhahn
I heard this case so so many times in chemistry and I religiously used to look at the chart specifying specific glove types for specific chemicals and made sure I changed my gloves constantly
@@user-hb6sb5ig6i I saw the link and shortly before clicking it I thought: "I bet its the video from Chubbyemu wich I watched a while back." I love it when life is predicable.
To add some info on lab coats: NEVER use coats containing polyester, use (at least) 100% cotton coats, or flame retardant ones. While cotton is flammable, it burns much slower and mostly turns into coal. Polyester will melt when on fire and can melt into the skin, leading to really nasty wounds.
I'd say polyester has it's places. Some reactions I do don't involve flammable material and the ones that do, I just use cotton. But for some distillations and reactions, polyester is just fine. You are correct though, polyester is not fun when on fire.
@@Andrew-my1cp Yes, e.g. in biochem classes and galenics, we were fine with polyester coats; and to an extent in organic chem classes. Everywhere we didn't have open flames so nothings is gonna catch on fire unless we are very stupid and deserve it
@Corvus Morve Holy fuck man. Looks like I'll stick to cotton for damn near everything. I use oils baths a lot but they are on the ground and only a couple hundred mLs of mineral oil but still.
The problem is that at my school, the eye wash stations are all rusty, because they're never checked over, and we do use potentially harmful chemicals. (obviously not now, as like the entire world is closed). It's really stupid they don't check on or change out a required safety feature. The district would much rather use their money to change out every trashcan in the school and paint over the doors than change out something that can save someone's vision, which in the long run will cost the district THOUSANDS when there's a lawsuit after a kid lost their sight because the eye wash water was full of rust and it just damaged their vision more in the long run
Duck. Exe not buying it. A quick Google search comes up with sink-mounted eyewash coming in around $75, and full shower with eyewash combo costing about $550.
Safety is certainly extremely important in every field, but particular in chemistry due to how volatile and/or toxic chemicals are handled and made. Accidents will happen, preparation means you can deal with them.
i think it should also be mentioned when talking about clothing and fire that cotton or wool will burn but sythetic materials like nylon and polyester will burn and melt to the skin like napalm causing nearly instant burns which is why synthetics should never be worn arround fire.
I was honestly surprised he didn't recommend 100% cotton coats. In my limited lab experience both minor accidents (no damage caused fortunately) were related to burners and fire. I do not like the idea things melting into my skin.
@@viporal7898 What the fuck is your issue, grammar isn't the point here (and besides they didn't make any mistakes, if you're talking about their username, it's _just a username_ and is not meant to be grammatically correct)
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.
Also - totally recommend getting a cheap pair of scrubs for chemistry work. Firstly there's the price, secondly there's the awesome pockets, and thirdly you won't be as sad when you have to toss them because you got biocrude oil on them and it Won't. Come. Out. Ever.
I appreciate you spreading this knowledge to your less experienced audience. I personally have no chemistry experience, but I do restore classic cars as a hobby (ungodly amounts of flammables, poisons, blindness hazards), and I was glad to see that the rules I’ve practiced are very much the same as in your video. Everybody should understand that their workplace has the potential to seriously affect more than just the person working. Nothing bothers me more that seeing other hobbyists get their young children to help them sand the lead paint off their car with zero PPE, many times even in a closed garage with no ventilation
I remember, even by my second year in Chem labs, I was always wondering to myself why the TA and profs had to reiterate about safety precautions (PPE, no exposed skin etc) before big labs, I always felt like the point should’ve been understood by that time But without fail, there was always at least one, if not 3-4 people that would show up in flip flops/ shorts, forget goggles and gloves etc
Aspirant medics and nurses: this also counts for you in many times. It's just as easy to get something contaminated with some infection or disease splashed on you than a chemistry to get acid on themselves. You also don't want to put immunocompromised patients in danger.
I've gotten the impression that medical safety is relatively different though, like isn't there debate going on about if lab coats should be worn at all in hospitals because they're vectors?
4:24 my trick for having to wash your eyes out with a standard tap is to just cup the water in your hands and bury your eyes in the water, roll them around a bunch and blink a ton, it’s not ideal, but in an emergency it’s better than nothing. Edit: another good thing to point out is that PPE is the last line of defence. The primary means of keeping yourself safe is to attempt to remove unnecessary dangers before trying to put ppe between you and it.
I can see this as a problem for some People like Me because i personaly cant hold my eyes open even if water gets in them i wont be able to hold them open widout my hands if there is a chemical inside of them
theclockmaker yeah this is just from my personal experience of having gotten gasoline in my eyes, growing up on a farm, shit happens and you don’t necessarily always have a proper eye wash. It could potentially be done by filling up the sink all the way if it’s large enough to fit your whole face in. But you’d certainly want to still be washing your eyes while the sink is filling up.
@@Patmccalk Dont get Me wrong im not saing thats a bad advise its actualy a good one but i know for my self that it wont work ive had an acsident with my grandfather while we were building some thing i cant remember what he had some concrete liquid splash in his eyes and i had to use a 10 liter botle of water to help him wash his face and he did what you sad but a few years later same thing hapened to Me and i coudnt do it and he ended up pouring the water on my face while i was holding my eye open
It's honestly really amazing and admirably responsible (and reassuring?) of you to hear all the precautions you take behind the scenes, especially because it's easy to get used to the general chaos you (safely) cause in the lab
I found just how useful labcoats are when I tried to weather one for a film shoot. Turns out it's difficult to burn something that was designed not to burn...
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.
@@marshmallowmountains4636 glad she was chill about losing the pants in class lol, way too many people would have sadly claimed sexual assault or something dumb
@@beebadoobie8429 Damn I never thought about that. That kind of needless accusation doesn't really happen around here that much. Or at least nowhere near as often as other places.
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.
Those things can burn with a faint blue flame that is hard to spot in well lit environments such as a chemistry class, I guess the teachers had his eyes peeled for that eventuality. It would have been better to not let her get anywhere close to the burner in the first place, obviously.
I was in 8th grade science class in the early 90s, when big puffy rolled bangs were still somewhat common. A girl got too close to a bunsen burner and her hair flash-burned. A second or two, no more, and her bangs were just gone.
I have a license in cosmetology and have seen all sorts of hairdos, but I cannot imagine what a teardrop of hair in the front looks like lol I’m imagining the “hair loopies” Katara from Avatar: The Last Airbender had on the sides of her face.
I'm glad you covered basic chemistry safety. I go to school in biotechnology, and in a BSL-1 laboratory for right now. Safety is extraordinary important. This was also a good reminder to me that I should probably listen to my teacher when she says to wear full PPE.
Your eye shower looks like a blessing compared to our school lab's. I've never actually seen it used in an emergency, however when it was demonstrated it was basically a shower Plug, however as soon as started there is so much pressure that the entire room was filled with water particles and we've since been scared of that sink
Nile. you just included All the mistakes that I was doing and unaware of. Shortly, you just saved my life. I don't even know how to thank you for reminding me about all these things.
The only time i ever "hurt" myself doing backyard science was when i burned my hair off trying to make wood ash to turn into Lye. Big 'ol flareup from the jet stove and i was WAY too close.
I once got some KOH on my hand because I was wearing short sleeves when taking apart a battery. It sprayed KOH everywhere, it hurt for a few days, luckily no scarring.
this is so true. there was this one time where me and my friends got bored, so we mixed together a bunch of highly strong corrosive liquids together, he didn't wear goggles or a face shield though, and got a huge burn on his face. he had to be sent to the hospital I think, and still has a mark on his face. the ppe I wore thankfully protected me.
Biggest accident I was involved in: A fume hood had the ventilators installed upside down after being repaired. The first analysis I performed involved chloroform -- which acutely stopped me from moving on to the more dangerous analysis scheduled after that. Lesson: Double check your fumehood airflow every time you use it!
I cannot even begin to express how informative and useful this video is. You packed a ridiculous amount of safety information into these video and showed so many cool examples to demonstrate what you were talking about. Your channel is seriously so awesome! 👏

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.
When I was attending biosafety classes, I learned that PPE should be the last barrier and engineered barriers are the most important level of protection. This video should be mandatory for research labs!
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.
Now that you've covered the safety measures, it would be really great if you could also do some videos on the basic lab techniques that are widely used for most experiments (eg. distillation, column chromatographies/tlc, rotary evaporation etc.) since there aren't that many sources of information for these on youtube and those that exist are usually poorly explained or extremely out-of-date.
Mr. Nileblue, thank you so much for thus video. I'm going to save it back and it will be required watching for some of my younger friends. I'm in my 50s and have learned many things the hard way. I still have the use of both eyes, no extra holes and all of my digits. I have lead a colorful life wearing many different hats and PPE from SCBA air supplied suits to lab coats in an automation lab. Life has been good to me. Thanks again, I'm a new subscriber. I enjoy stuff like this.
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.
Chemistry is dangerous, that’s why I watch you do the dangerous stuff and still gain the benefits of entertainment

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.

I AGREE
My father always told me "Son, there are accidents, and then there is carelessness. Carelessness is putting yourself in a position to have an accident."
My father always told me "I wish you came into this world stillborn".
"There are accidents and there is cowardice. Cowardice is when you won't do something because an accident will happen"
your father was a wise man.
Reminds me of some firearms experts saying "almost all of what people call 'accidental discharge' is actually negligent discharge."
My shop professor always said "Don't be sorry just be right"
If you're playing with chemistry you may not have time to be sorry
A friend of mine was doing everything right. Solid A+ uni chem student. Someone else mislabeled one of the chemicals he was working with, and he ended up with permanent scarring on his face when combining that mislabeled chemical. Even the most trained, methodical chemist can end up in danger.
Waldegrave that’s one way to get thrown out of a lab, to not label or wrongly label chemicals, exactly for this reason.
The simple idea of having a mislabled chemical is a huge "gtfo" for whoever did it. Especially in stuff like aerospace, imagine messing up a hypergolic fuel mixture that uses hydrazine or something of that style. Instant explosion or corrosive/gas.
i hope the person who mislabeled it got in major problems and pays for all medical bills from the scarred person and than some more issues too

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.
Ahh ja Hauptschüler machen Hauptschulsachen, geil

Also: Another PPE for people with long hair is to have a hair tie or hair net, I don't know how often I've been millimeters away from catching my hair on fire.
I have become familiar with the smell of burning hair before I finally started being more careful. My hair has never caught fire but it really should have
And for those who only have hair ties as their option, always put your hair into a bun (not a ponytail) that way it’s very unlikely to get caught in something.
I always wondered why my high school AP bio teacher told me to tie my hair into a bun instead of a ponytail, but after hearing disastrous stories in college, I finally knew why that was the case

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.
Ouch! Thanks for sharing, and glad you were OK.
Oh my god you’re so lucky it didn’t take your eyesight 😰, I’m sorry you had to go through that, you must’ve been so scared!
Nasty, glad you're ok.
As a kid, I used to disassemble used up 4.5V zinc carbon batteries for the carbon rods, to use for carbon arcs and electrolysis.
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.
Washing litium with water, bad thing! But I don't blame you, you were 15, and I'm glad to know you are fine after all
I had a friend as a kid who had a glass eye, apparently they'd poked it with a pair of scissors. So glad I have good eyesight, not something I take for granted. Gotta take care of these peepers :^) Glad it didn't go worse for ya.
I've been thinking for a long time about making a video about the difference between real danger and perceived danger. It's often easier to see the danger in flashy and fiery TH-cam videos, while being careless with mundane (but statistically extremely dangerous) things like ladders and razor blades. I think an accurate perception of real danger is one of the most critical steps for safety in all activities.
I think this is because we use ladders and razor blades in our everyday life so we have the feel of fake safety and dont care. Flashes, arcs and tesla coils are something special so we are aware because we never seen something like this before and are aware.
People often feel invincible until it's too late, I agree completely.

Proper eye wash stations are designed to pop the caps off automatically from the water pressure, saving you precious seconds that can make a big difference. Especially when you're blinded/have your eyes closed, it could cost you a lot of time trying to get the caps off.

Good Video, I am a chemistry professor in Wisconsin and i always try to teach my student and scholars about safety and they never listen! after last year's incident (A 16 year old kid accidently swallowed Sulfuric Acid and was rushed to the hospital!) the school principal was trying to find a educational video about LAB SAFETY to show to all the students and then we found this video! almost all of the students knew who you are and loved your channel so they listened to you and it worked!

Swallowed sulfuric acid? How did he manage that? Eating or drinking anything in a lab is a good way to end up in the hospital

@@filipilic2451 what the fuck really
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.
@@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.
@@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.

Classic risk compensation. It's like how people drive faster wearing seatbelts. There's the thought experiment that says installing a big spike in the center of the steering wheel would make people drive more carefully.
Ugh I needed to go to a store the other day and the cashiers had started wearing gloves... and that was it. They weren't changing them between customers, and were still touching everything they normally would, and thus were only possibly barely protecting themselves *if* they remembered not to touch their faces or clothes until they safely take the gloves off. It just seemed borderline pointless given the risk of it adding a false sense of security, because I know it would be impractical to change gloves every single time they check out a new customer. They might as well just wash their hands or figure out a hand free way. That said I treat all my grocery bags as dirty, and sanitized everything I bought myself too.

Considering the amount of dangerous chemistry thrown around on TH-cam 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!
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.
@@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.
@@_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.
@@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.
To be honest, even size-fitting gloves wouldnt have really saved you unless you wore thick nitril gloves, especially made for acids
As an electro-mechanical engineer, it's always fun and interesting to see how the other disciplines take safety into account. I don't deal with too much more than high heat and fast objects, but you never know when some experiment will have a chemical situation.

Here's a free safety tip: If you're heating something horrible on a burner, don't forget about it. Everyone else in the lab will be really angry when you poison them.
Also, if you're working with UV, don't leave the light on all day. The sunburn is going to be funny looking.
And if you spill radioactive powder all over yourself and the floor, don't just run home, leaving it for someone else to deal with. Your coworkers WILL use the Geiger counter to track your radioactive footprints to your assigned parking space.

I nearly lost both my eyes in a lab accident and my goggles barely saved them. Nearly lost them again in the field handling a chemical pump but my glasses saved me. You cannot stress enough how important eye safety is.
On the PPE section, specifically gloves, even professionals make mistakes. I can't remember the exact details, but there was a case that this researcher working in (I believe) an MIT lab was dealing with an organic mercury compound and had been using Nitrole gloves; well it turns out the gloves are permiable to the compound. The researcher had just a drop fall on the gloves and thought nothing of it, she didn't immediately change them and went home later as usual. She absorbed an incredible amount of mercury from that drop and it shriveled up her brain like a raisin. I can't remember if she survived long term, but in the short term she had permanent brain damage.
So those points about checking compatibility and changing gloves if they become contaminated are very important indeed.
I know what you are talking about and that woman died in 1997. At the time they thought those gloves worked for organic mercury and her accident revolutionized PPE around organic mercury specifically, but extensive testing across the board was also done due to that incident as well. She was wearing 3 sets of gloves and also did take them off immediately, but the chemical still made it through. The specific type she was exposed to was lipid soluble (fat soluble) and got stuck in fat cells in her hand. As those cells broke down normally she got microdoses floating in her blood. Over time these micro-doses brought the mercury to her brain and CNS and caused progressive neuro degeneration until she died roughly a year after the accident. She was a world famous researching covering heavy metals and their effects on humans and when she figured out what was happening and that she was likely going to die she called her colleagues from around the world and told them to use her as a case study. As a result her death, while horrible and slow, is one of the best documented case studies ever made about chemical toxicity since the discovery of the extensive human testing documentation at the end of WW2. She went deaf, blind, lost faculties and reasoning over time, and eventually could not even walk or speak at all. Eventually she entered a vegetative like state, but it was noted that sometimes she made expressions and noises that sounded like she was trying to scream. Eventually the nuero degeneration was too severe and she died as a result of acute mercury poisoning. This was even after months of treatment with a medicine that allowed helped the kidneys pull mercury out of the blood. A large consensus as to why she still died is that the medicine is not effective at removing mercury that is already bound to fat cells and the CNS is almost entirely composed out of fats.
ChubbyEmu has a narrated TLDR'd version of the case study and story if you are interested.
Her name was Dr. Karen Wetterhahn, a professor of chemisty at Dartmouth college. She was exposed to dimethlymercury in August 1996 and died from the exposure in June of 1997.

The most overlooked safety rule in chemistry is "don't leave anything between you and the emergency hood vent override, window, door, fire-alarm and 5 mile distance"
I'd add onto this: If you see a man in a lab coat running, you also run. I have seen (and been in) several fires because a reaction went out of control and ended up causing a fire that detonated (yes, boom) the lab gas pipes. if a lab is on fire, GET OUT then call the fire department.

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.

3:18 This part everyone, especially Chemistry students or new and inexperienced Chemists, should take note of. As an A level Chemistry student I observed the need to keep PPE on even when you're done with your practical as others might still be working; there were these two girls that were finishing off their Qualitative Analysis of Ions practical. 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.
Wear your lab coats, chemically resistant gloves and goggles!
I would even wear a mask, preferably one that is fluid resistant.
This makes a good example of safety though. Even the comment sections of educational videos often have input.

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 :(
She had the good reaction to go in the shower, But sadly that doesn't always fix a problem.
That shouldn't have been blamed on her. Human reaction can't always be controlled.
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.
Showering to put out a fire of Sodium and Potassium. Not the best strategy.
How much metal did she use for God's sake?
I wish schools would use this video for proper chemistry safety. It's to the point, entertaining, informative and high quality.
It may have been helpful to mention Karen Wetterhahn's case when talking about the gloves.

NEVER use coats containing polyester, use (at least) 100% cotton coats, or flame retardant ones. While cotton is flammable, it burns much slower and mostly turns into coal. Polyester will melt when on fire and can melt into the skin, leading to really nasty wounds.
TRAS̸H DØVE Also I heard polyester can accumulate static charges and basicly static electricity + flammable organic solvents is pretty terrible combo.
I'd say polyester has it's places. Some reactions I do don't involve flammable material and the ones that do, I just use cotton. But for some distillations and reactions, polyester is just fine.
You are correct though, polyester is not fun when on fire.
@@Andrew-my1cp Yes, e.g. in biochem classes and galenics, we were fine with polyester coats; and to an extent in organic chem classes. Everywhere we didn't have open flames so nothings is gonna catch on fire unless we are very stupid and deserve it
@Corvus Morve Holy fuck man. Looks like I'll stick to cotton for damn near everything. I use oils baths a lot but they are on the ground and only a couple hundred mLs of mineral oil but still.
@Corvus Morve How hot was the oil? I read polyester melts at 295C. That's really freaking hot! I can't even bring my oil baths to that temp.
The problem is that at my school, the eye wash stations are all rusty, because they're never checked over, and we do use potentially harmful chemicals. (obviously not now, as like the entire world is closed). It's really stupid they don't check on or change out a required safety feature. The district would much rather use their money to change out every trashcan in the school and paint over the doors than change out something that can save someone's vision, which in the long run will cost the district THOUSANDS when there's a lawsuit after a kid lost their sight because the eye wash water was full of rust and it just damaged their vision more in the long run
@PhoenixUltraMotive it's not that... It is because it's cheaper to repaint and replace the trash cans than it is to replace an eye wash station.
Duck. Exe not buying it. A quick Google search comes up with sink-mounted eyewash coming in around $75, and full shower with eyewash combo costing about $550.
In my school, the eyewash stations are fine but we were never taught how to use them :T
Wow...
@@marstv9048 I understand that, but at least regular test runs of it won't make rust form.
Safety is certainly extremely important in every field, but particular in chemistry due to how volatile and/or toxic chemicals are handled and made. Accidents will happen, preparation means you can deal with them.
i think it should also be mentioned when talking about clothing and fire that cotton or wool will burn but sythetic materials like nylon and polyester will burn and melt to the skin like napalm causing nearly instant burns which is why synthetics should never be worn arround fire.
It's not the synthetic origin, but the specific nature of each material. Some of the most fire-resistant textiles are synthetic.
I was honestly surprised he didn't recommend 100% cotton coats. In my limited lab experience both minor accidents (no damage caused fortunately) were related to burners and fire. I do not like the idea things melting into my skin.
It depends on the synthetic; if they're made out of certain types of plastic, then yes, consider it more dangerous than cotton.
What a surprise. The furry is too stupid for grammar
@@viporal7898 What the fuck is your issue, grammar isn't the point here (and besides they didn't make any mistakes, if you're talking about their username, it's _just a username_ and is not meant to be grammatically correct)
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.
Also - totally recommend getting a cheap pair of scrubs for chemistry work. Firstly there's the price, secondly there's the awesome pockets, and thirdly you won't be as sad when you have to toss them because you got biocrude oil on them and it Won't. Come. Out. Ever.

I appreciate you spreading this knowledge to your less experienced audience. I personally have no chemistry experience, but I do restore classic cars as a hobby (ungodly amounts of flammables, poisons, blindness hazards), and I was glad to see that the rules I’ve practiced are very much the same as in your video. Everybody should understand that their workplace has the potential to seriously affect more than just the person working. Nothing bothers me more that seeing other hobbyists get their young children to help them sand the lead paint off their car with zero PPE, many times even in a closed garage with no ventilation
I remember, even by my second year in Chem labs, I was always wondering to myself why the TA and profs had to reiterate about safety precautions (PPE, no exposed skin etc) before big labs, I always felt like the point should’ve been understood by that time
But without fail, there was always at least one, if not 3-4 people that would show up in flip flops/ shorts, forget goggles and gloves etc
That's exactly the point
Honestly, if you're not willing to follow basic safety, stay out of the lab
@@thespudlord686there are so many idiot students who should not be in laboratories.
@@thespudlord686 Or just run your own lab of one where the only person at risk is you.
Oh them? We call those people uh... COMPLETE MORONS
Aspirant medics and nurses: this also counts for you in many times. It's just as easy to get something contaminated with some infection or disease splashed on you than a chemistry to get acid on themselves. You also don't want to put immunocompromised patients in danger.
I've gotten the impression that medical safety is relatively different though, like isn't there debate going on about if lab coats should be worn at all in hospitals because they're vectors?
4:24 my trick for having to wash your eyes out with a standard tap is to just cup the water in your hands and bury your eyes in the water, roll them around a bunch and blink a ton, it’s not ideal, but in an emergency it’s better than nothing.
Edit: another good thing to point out is that PPE is the last line of defence. The primary means of keeping yourself safe is to attempt to remove unnecessary dangers before trying to put ppe between you and it.
I can see this as a problem for some People like Me because i personaly cant hold my eyes open even if water gets in them i wont be able to hold them open widout my hands if there is a chemical inside of them
theclockmaker yeah this is just from my personal experience of having gotten gasoline in my eyes, growing up on a farm, shit happens and you don’t necessarily always have a proper eye wash.
It could potentially be done by filling up the sink all the way if it’s large enough to fit your whole face in. But you’d certainly want to still be washing your eyes while the sink is filling up.
@@Patmccalk Dont get Me wrong im not saing thats a bad advise its actualy a good one but i know for my self that it wont work ive had an acsident with my grandfather while we were building some thing i cant remember what he had some concrete liquid splash in his eyes and i had to use a 10 liter botle of water to help him wash his face and he did what you sad but a few years later same thing hapened to Me and i coudnt do it and he ended up pouring the water on my face while i was holding my eye open
@@Patmccalk Oh man, I was under my car repairing a fuel line once, and got an eyeful of gasoline. Not fun!
KingNast somethin I would honestly not wish upon my worst enemy.
It's honestly really amazing and admirably responsible (and reassuring?) of you to hear all the precautions you take behind the scenes, especially because it's easy to get used to the general chaos you (safely) cause in the lab
I found just how useful labcoats are when I tried to weather one for a film shoot.
Turns out it's difficult to burn something that was designed not to burn...
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.
that's a damn good teacher
@@questionmarkquestionmarkques Yeah she was awesome! She reacted very quickly and probably saved that girl a lot of pain.
@@marshmallowmountains4636 glad she was chill about losing the pants in class lol, way too many people would have sadly claimed sexual assault or something dumb
@@beebadoobie8429 Damn I never thought about that. That kind of needless accusation doesn't really happen around here that much. Or at least nowhere near as often as other places.
@And-Nonymous Um, yes that's where I'm at?
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.
Those things can burn with a faint blue flame that is hard to spot in well lit environments such as a chemistry class, I guess the teachers had his eyes peeled for that eventuality. It would have been better to not let her get anywhere close to the burner in the first place, obviously.
I was in 8th grade science class in the early 90s, when big puffy rolled bangs were still somewhat common. A girl got too close to a bunsen burner and her hair flash-burned. A second or two, no more, and her bangs were just gone.
I have a license in cosmetology and have seen all sorts of hairdos, but I cannot imagine what a teardrop of hair in the front looks like lol
I’m imagining the “hair loopies” Katara from Avatar: The Last Airbender had on the sides of her face.
equesdeventusoccasus
It’s called a Bunsen burner.
What's a Brinson burner
I'm glad you covered basic chemistry safety. I go to school in biotechnology, and in a BSL-1 laboratory for right now. Safety is extraordinary important. This was also a good reminder to me that I should probably listen to my teacher when she says to wear full PPE.
Your eye shower looks like a blessing compared to our school lab's. I've never actually seen it used in an emergency, however when it was demonstrated it was basically a shower Plug, however as soon as started there is so much pressure that the entire room was filled with water particles and we've since been scared of that sink
Thats bad. Even in an emergency NOTHING should fly around in a chemistry lab. Even water.
@@foty8679 I imagine the water droplets filling the room, landing in concentrated acid...
Nile. you just included All the mistakes that I was doing and unaware of. Shortly, you just saved my life. I don't even know how to thank you for reminding me about all these things.
The only time i ever "hurt" myself doing backyard science was when i burned my hair off trying to make wood ash to turn into Lye. Big 'ol flareup from the jet stove and i was WAY too close.
Damn, that's why I wore motorcycle helmet when doing backyard science, just in case
I once got some KOH on my hand because I was wearing short sleeves when taking apart a battery. It sprayed KOH everywhere, it hurt for a few days, luckily no scarring.
@@Carolus_Tsang damn, you're lucky for having your eyes unharmed.
this is so true. there was this one time where me and my friends got bored, so we mixed together a bunch of highly strong corrosive liquids together, he didn't wear goggles or a face shield though, and got a huge burn on his face. he had to be sent to the hospital I think, and still has a mark on his face. the ppe I wore thankfully protected me.
Why would you even mix those liquids
@@KeaveMind because yes
@@KeaveMindthey were bored
You should have told him to wear protection. And if he said no, just tell him to leave the god damn lab until he came back with protection on his face
@@squishyghost1234 that is very true lmao. but we were chemistry fans that were teenagers, which doesn't mix well at all.
Biggest accident I was involved in: A fume hood had the ventilators installed upside down after being repaired. The first analysis I performed involved chloroform -- which acutely stopped me from moving on to the more dangerous analysis scheduled after that. Lesson: Double check your fumehood airflow every time you use it!
I cannot even begin to express how informative and useful this video is. You packed a ridiculous amount of safety information into these video and showed so many cool examples to demonstrate what you were talking about. Your channel is seriously so awesome! 👏

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.
Don't know why but, his voice is very relaxing to listen to.
When I was attending biosafety classes, I learned that PPE should be the last barrier and engineered barriers are the most important level of protection. This video should be mandatory for research labs!
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.
Now that you've covered the safety measures, it would be really great if you could also do some videos on the basic lab techniques that are widely used for most experiments (eg. distillation, column chromatographies/tlc, rotary evaporation etc.) since there aren't that many sources of information for these on youtube and those that exist are usually poorly explained or extremely out-of-date.

Mr. Nileblue, thank you so much for thus video. I'm going to save it back and it will be required watching for some of my younger friends. I'm in my 50s and have learned many things the hard way.

Life has been good to me. Thanks again, I'm a new subscriber. I enjoy stuff like this.
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.
