Safety Video

Would you share a link for your current lab coat? I'm debating doing some film development, and most development kits have chemicals that warrant more PPE than a T-shirt.

You brought up fire resistant lab coats in your video. Just wanted to point out that clothing labeled “FR” isn’t usually heat resistant in the manner that most people would think it is. The FR label is done to show that the coat meets regulations protecting workers against flash fire. The materials used in FR (ie NOMEX) won’t survive constant heat (cotton actually shows more resistance to burning when exposed to a constant flame). They are just designed to prevent air flow that would allow flammable gases to reach your body if ignited. The sleeves that bunch around your arms and the higher neckline are likely there to serve the same purpose. In non-lab coat garments those are standard features. In non-lab coats (industrial environment such as an oil refinery) you would normally have to wear a single piece full body suit or tuck in your shirt to prevent gasses from getting trapped inside the protective layer.

I tried looking up the labcoat you showed that was hydrophobic. I can only find one well known company that makes those, but the cost is ... prohibitive. There are other clothing choices that are much more forgiving on the wallet. If you have a pointer to where you are buying these, it might be helpful.

thanks.

This was excellent!

Well done!! 👍✌️

That' s the same thing my professor told me, ether would have been worse for sure, but still the point remains how important respecting security measurements is! Cause you never know how terribly wrong can even a simple step go

I also have Potassium ferrocyanide if with acid equals deadly HCN but i never have acid near it also bases and heat can release HCN too.

When I mixed antifreeze with iron sulfate and H202 35 percent it splashed big time guess what saved me my faceshield! Thank god for that.

Good video... a necessity for those practicing amateur chemistry

That's very weird because chloroform usually isn't that potent. Like ether, you usually need to really breathe in a lot over a period of time. Maybe you are just very sensitive to it. But, the point you made is still very good, it wasn't even your fault that it spilled!

about people you share your space with... i'm studying chem rn in university, a friend of mine needed some drops of chloroform to bring iodine in organic phase... well, two drops fell in front of me from the pipette and after something like 5 seconds i was on my knees purple in the face almost falling asleep, weird sensation i gotta say :P

I listen to music, but only in 1 ear and I turn it off if I ever have to do something that requires any level of concentration.

Nile Red

I have just been very busy and have not replied to a lot of messages. I am trying to get to them, but it is hard to quickly respond to them all.

Nile Red

There were a few times when I thought you were as carefree and clumsy as a panda, but it's good to know that you have a lot of knowledge about safety. I am very happy that you have recorded this video. You inspire many people, who often have no clue how dangerous chemistry is. The chemical laboratory is a bit different from a pharmacy (for example, I can't listen to music while working and I have to be constantly focused on what I do, otherwise I could accidentally poison somebody). The subject of safety is very extensive, but you have grasped the basics just perfectly.

@NileRed its great! I like it and if i willnt have googles i will be blind completely. And i also have question: I send to messages and no one get reply. I am 1$ patron. If I want to get replys should i became 5$ one?

It will be released publically! Patrons just get to see it first and give their opinion on it :)

Nile Red

There are definitely a lot of things to look out for, and when making this video, I even noticed some mistakes that I was doing. For example, I had a couple chemicals stored improperly, so now I am re-organizing everything.

Nile Red

I actually have a pair of them! However, I only use it if what im doing in particularly angry. To get around my goggles, it would have to splash at an extremely weird angle. It would have to be right under me, which never happens if its sitting in front of me on a bench. I also have the glass of my fumehood that completely blocks my face from the chest up.

Nile Red

Very good point. That goes along with the misconception that to get rid of acid/base you need to neutralize them. No...just wash it away with water, you will hurt yourself more throwing acid/base on.

Nile Red

Maybe you should start thinking ahead! :)

Nile Red

I meant to add that but somehow forgot to put it in. Ill try and put a note or something in there

Nile Red

Yeah it was meant to be fundamental and I still wasnt able to include a lot of very basic stuff

Nile Red

The video was blurry?

Nile Red

It's just very hard to do that because there are SO many small things that you can only get from doing it a lot. Even if the video were insanely detailed, I feel like it still wouldnt be close to being taught practically.

Nile Red

I will try and add that in the final video description or something. Ill think about if i want to do a followup video. For now, I dont have any plans though.

Nile Red

this video was good. I think it shouldnt be for patreon. It should be for all people. @NileRed

I am not a chemist, and I am absolutely mind blown by this video. I learned a lot. Diagram to know where to put waste, special fridge, wow man, all those precautions! I guess I will appreciate even more your videos now ;) Thank you!

Great video, the glove section is particularly strong. Splashproof safety goggles form a proper seal to your face preventing anything from getting to your eyes. The goggles you are wearing won't prevent splashes from the most probable direction, the bench up towards your face. Even nice ones are far under $20. https://www.uvex-safety.com/en/products/safety-glasses/7658/uvex-megasonic-goggles/

The only thing I think you missed is this is specifying cold water rinsing. I worked on a sanitation crew for a long time and I can’t tell you how many time I’ve seen people bypass the chemical shower or eyewash station to go for the sink because they believe hot water will remove the chemicals faster. Needless to say it has bad results if someone isn’t around to stop them. One coworker who was well seasoned did just that after chemical inside his glove and ended up needing a skin graft. He was lucky he had a doctor that had experience in chemical burns. Most doctors would’ve amputated. On another note, it would be cool to see a series Of family friendly experiments.

Being a cook by trade I cant tell you how many times I could have avoided injury with just a little forethought.

You might have mentioned it and I wasn’t paying attention but having long hair tied up is a really important safety thing a lot of people forget! I personally usually go for a pony tail or bun, but plaits also work :)

Yes it’s a strong acid, though in tiny amounts on your hands at that concentration it won’t do much especially if rinsed quickly

Manuel Aparicio-Conde

Excellent primer. Just one thing. When you put the nitric acid on your finger at 7:55, you say, "it didn't react, or do much to skin," but for how long? If you left it on your finger, wouldn't it would eventually do some damage?

Michael Aichlmayr

I wish to applaud you. I am the senior director of Environmental Health and Safety for Case Western Reserve University. You made a very solid video. I would like to add a million other items of course but this is a very nice basic easy to understand introduction. Should you ever wish for help in this respect please feel free to reach out to me.

Thanks for this video, I really needed this! However, it's really blurry. I don't think it has anything to do with the glass in my eyes though.

Same definitely a very detailed video of technique and of how to properly do experiments safely

100% agreed with chemistry being the most interesting, and most dangerous. It's fascinating black magic. Could you put in the comments what brands/models you recommend for PPE? Maybe you could make a video that is "an introduction to chemistry and the lab", that allows viewers to do a basic reaction at home. I know there is some risk to that, but with the right warnings/disclaimers it would be pretty awesome.
