- This is a video that I've been wanting to do for a while and I did my best to cover some of the fundamentals of safety. However, there are still plenty of things that I couldn't include and this will not at all prepare anyone to jump into practical chemistry.

Totally agree with you John 👍
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.

@@SpaceDave-on8uv that thing melted my book cover because I don't realise it was super hot and I stupidly put it above my book.
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
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
Whether it is a hospital or a chemistry lab, you can't lick the floor
PPE DPI OR EPI are a standard in every job in every country
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.
@@blend3461 I'm referring to procedural precautions more than PPE.
"If I don't feel comfortable dealing with the worst possible scenario, then it's not something I should be doing."
Excellent advice.

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.
That’s terrible.😨
... this is about half of what I learned in my high school chemistry class. That is really, exceptionally sad
For us, we were being reminded from time to time about most things, and got heads up when using something dangerous
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!
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
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

You literally fail to understand the basic concept of time, and then judge others for doing something correctly during the time of commenting, asking others to look things up before talking shit, when you're the one who fails to understand the fundamental concept that things changes as time passes. How disappointing.
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.
[Tetra-Ethyl Lead has entered the chat]
i sure do love working with hexarigtuyglsadkjfhyurfgjhgieiswoooxnneesgeyeisitane
Ah, FOOF
The equal opportunity oxidiser. It's getting oxidised whether it likes it or not 🔥
but seriously how can you remember how to type that whole "Hexanitrohexaazaisowurtzitane" thing lmao
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.
Chubbyemu did the video about this case.
I have seen a video where 2 Russians were handling chromium trioxide and bromine and even 97% sulfuric acid without gloves.
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.

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.
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.
Im so sorry for your loss. Now he sees how beautiful his family that he created. ❤️
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
even if it was a accident, those accidents should not be forgiven for their lethallity

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
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
Always remember to wear your gloves, they will protect your hands and can also be turned into grape soda.

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'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.

And then there’s NileGreen…
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.
imagine if someone clueless decided to use the station before that...
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
@hawkturkey all the research students were there. This was after school
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".
Awww man....I laughed out loud to your 1 to 1 ratio comment. Thanks 😊 for the safety story
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
@@Malysitos I want to add it's better to keep it in a ponytail inside your collar if it's heavy enough that the bun may come undone by gravity.

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.

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.

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.
Glove stupid is so relevant to COVID-19
@@rapalo89 God yes, gloves and mask so take no other precautions. Those are the people to stay the furthest away from
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.

I feel like it's a good idea to occasionally reiterate the importance of safety and maybe make more videos of this nature.
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.

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.
safety data sheets are quite useful for knowing what precautions to take
look up one for each chemical too :)

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.
Great video, as a student I've seen many people who ignored some basic safety rules. Always felt uncomfortible working around that. Better safe then sorry.
Cody's lab: "Safety is our number 5 priority!"
I mean, living in his own mars water tanker is really safe considering the current situation
always lol
5 was a small number when he accidentally inhaled liquid mercury
hahaha,,, safety shoufld alwayts be your first priority, not number 5, not number 4, not number 3, not bumber 2m, number 1. maybe ya shouldnt have heaten all those chicken strimps/.
* stomps around in an old mine *
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
This is why I don’t mess around with chemistry and wouldn’t unless I had someone highly trained around me guiding me in what I was doing, or working with something that there was little to no danger of something going disastrously wrong. Love watching it though because it does interest me.

My father was (hes alive just retired) a middle school science teacher, and ine time he broke a bottle of acid and since then his sense of smell is mostly gone (i heard this story multiple times) so yeah lab safety is important
😮
Nile Red has the same problems. His nose is completely messed up and he cannot smell anything.
He seems so angry and passionate when talking about breaking safety procedures and its honestly so wholesome.
Bro shut the fuck up on your “wholesome” shit zoomer
....sooo hot! ;p
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.
This video makes me think about my chemistry lab course at highschool, in which they dedicated a lesson to safety precautions and then carelessly forgot to give us the protections afterwards. We worked with all kind of chemicals like acids ad basics without goggles or gloves, the tap was facing down like a regular one and no teacher ever seemed to care. Obviously we were teenagers and we trusted our teachers, but If think about that now I have goosebumps
They should show this in schools. Like we learn to use these but having these examples I think are really good in understanding exaclty why we need them.
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.
That is sad but it can happen. Actually fluoric acid poisining has a delayed effect up to 24h, so you want die instantly. You could inject and rubber the hand with calcium gluconate to prevent an accute intoxication. Fluoric acid is not very strong, but fluor will bound to yours cations in blood, causing nerves transmitting problems that could lead to cardiac arrest. So when working with it always use a teflon recipient and make sure to have a strong alkalin solution like NaOH to get it neutralised.
@@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.
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
That is true!

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.

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 😅

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.
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.
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.
I will always remember that one SciShow video where Hank goes over basic safety information that my teachers made us watch every year despite handling nothing more then salt and water
Cooking class, intermediate level?
Johnny drank some H2O but he won't do that anymore;
For what he thought was H2O was H2SO4.
I took three years of chemistry and only had two small accidents. The worst one was that I accidentally knocked over a graduated cylinder full of 12M HCl all over my lab notebook because the sleeve of my cheap lab coat caught the top of it. The cylinder didn't break thankfully and the only thing it did to my lab notebook was wrinkle the paper a bit.
The other one was more embarrassing than dangerous. I had finished taking my written lab final before most other people and I was cleaning up my glassware to check it back into the school. In order to dry my test tubes more quickly, I was using the air nozzle on the lab bench. What happened was that one of the test tubes slipped out of my hands and flew across the lab bench, shattering right next to someone who was still trying to take the test. No one got hurt, but it did startle the other student and embarrass me.
I would always carefully prepare for each of my labs, though, and I have to say that, despite initially being nervous about having to take a three hour class in the form of a chemistry lab, it ended up being my favorite part of taking chemistry.
Oh there was one other fuck up that I made and I can't believe that I almost forgot about it because it was probably the most dangerous one! When I was in organic chemistry, I had a little cuvette of some chemical I had made (can't recall which one it was since we did a lot of this in that year of chemistry) that was dissolved in dichloromethane. I had put the sample in the GC/MS to see if I had made the product I had expected and then put the cuvette into the top pocket of my lab coat. All that was fine but I forgot to take it back out of my pocket before leaving the lab and I only realized that it was still in my pocket when I went to wash my lab coat at home. At least I found it before I threw my lab coat in the wash. I was mostly just embarrassed that I had taken something home that belonged to the school but before I could take it back, to my horror, the DCM had completely evaporated from the cuvette into my little apartment. So far, nothing bad has happened to me or to the cats who also lived there with me, but it's less than ideal to evaporate any amount of DCM into one's apartment. It was less material taken home than the time that fruit fly mutants somehow ended up coming home with me from the genetics lab but they were only dangerous to the fruit in my house, although anyone who might have seen me following fruit flies around my kitchen with a magnifying glass might have assumed I was crazy instead of a scientist (assuming there is necessarily always a difference between the two).
Anyway, safety among the top three.
One more thing: amateur chemistry is pretty necessary. It's called cooking and it's the kind of chemistry that I kind of suck at.
"stupidity last", words to live by
That just reminds me of how my chemistry teacher once had throat cancer from transporting radioactive fertilizer behind his neck without the proper lead casing
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
