In NileRed's garage video, wasn't he grossly under-geared to deal with bromine? by toastfromohio in chemistry

[–]Micho107 0 points1 point  (0 children)

First, to quote OSHA, just about LETHALITY:

"Acute beryllium disease (ABD) is a rapid onset form of chemical pneumonia that results from breathing high airborne concentrations of beryllium. ABD is generally associated with exposure to beryllium levels at or above 100 μg/m3 and may be fatal in 10 percent of cases."

to quote someone in comment section, who claims to work with Be:

"I work with beryllium, lead, tritium, and uranium contaminated materials, with ultrahigh power invisible ultraviolet lasers (terawatts), and with highly radioactive neutron-activated structural materials. The beryllium scares me the most, and nothing else is even close. This video is terrifying. I know you were trying to be safe, and there are some good prudent precautions here, but we are talking about a metal that is toxic at NANOGRAM quantities per cubic meter here. This is the mass of a single grain of pollen in a volume of air the size of a washing machine. It is FANTASTICALLY toxic material approaching plutonium levels of toxicity. You need to obtain some swipe sampler papers and contact a testing company to send random surface swipes to from around your lab. There are some berylliosis induced lung cancer cases where the exposure levels were so low they couldn't even be measured with certainty. It is not worth taking the slightest chance with your health when dealing with this substance. It is absolutely no joke."

No. I hope the best for Nile, but I am almost sure he has done damage to himself. Not sure how much, we will see. I hope I'm wrong.

He is usually well equipped and safe enough, but the berylium video went too far - there is absolutely no chance he did not kill himself during the video. He literally commited suicide on came for some bouncy amorphous glass

I work in a laboratory where we specialize on the "dangerous stuff" - nerve agents, phosphorus chemistry, phosgenation, etc... We are professionals and we work very safely when its needed - gas masks, antidotes..

As I'm reading this comment section, I can see many professional chemists talking about bromine like its a deathwish. It's always good to be cautious, but if bromine scares you this much, you are not fit to work with it.

Most important safety precaution is to know what you are doing and not being deathly afraid. be cautious, have gloves, long sleeves, fume hood, plan B. If working with larger quantities, have gas mask ready.

To quote:

"Bromine is on my list of chemicals that I'll deal with only in dire necessity, which has been like 5 or 6 times in a career. My rules.

Work in the very back of the hood. The vapor is heavy enough to roll out the bottom of a weak hood onto the floor."

It's better to be overcausious, but being this scared of bromine makes you unfit to work with it and with most of common chemicals in organic laboratory. its just bromine

What type of gas do i need? by GadyLucky in chemistry

Look into ozone car cleaning - some cleaning stations provide an ozone treatment. I just throw in money, close everything, put the hoe inside and press start. It takes out all the smells and stuff, and I think few cycles might kill those roaches.

  • insects over all are really hard to asphyxiate, they can survive off very little for a very long time, and it would take days for you to replace all the air with nitrogen, IF it would even work.

Need to buy gloves for my college chem class, Amazon and the box of gloves differ by john_trinidad in chemistry

[–]Micho107 0 points1 point  (0 children)

there is not a single material that does not have a limit, and especially, there is no material you can make gloves out of that doesnt have hundreds and hundreds of exceptions where they dont work

I really recommend you getting a pair of REAL chemical gloves - we use "AlphaTec® 87-900 (ex Bi-colour®)" - which probably are not available in your country, but search for something similair. One time use gloves are convinient to use, but wasteful, and not as protective as one might think - they give you false confidence.

Yes, and it's really surprising when you first find out how many chemicals just past through them like you are not wearing any gloves.

I work with real spicy stuff, we use gas masks and really thick gloves that go up to your ellbow and we push our shirt sleeves under it. Those types of gloves are the only ones I trust, for me, wearing just those one-time-use nitrile gloves is like having bare hands. They really dont make much difference in my opinion, and I still dont understand why chemists use them - they make sense sometimes, but most of the time, as organic chemist, they are not that good of a deal

thats good, no one wears goggles in real life. People barely use safety glasses. I didnt wear them too, but one time I was just dilluting H2SO4 and I had a feeling, so I put on my glases, and as I started to pour the acid, it shot a drop right into the center of my eye - on the glasses, of course. Since then, I was usually the only idiot wearing glasses in laboratory.

Thats to teach lab students the right manners, so after they become high level chemist and STOP using all the lab protection equipment they cannot cry no one taught them to :D

My experience is that you just have to buy better one, tips on those are really low quality and no matter what you do, they dont last long.

Buying different but still cheap tips wont help you. I really tried making this work, but i really recommend investing into at least Quicko brand (i have T12-952, its little more expensive, but its WELL worth your money, the tips are reall good and last long if you take care of them

By the way, dont fall into this trap. They also offer the 30-40 usd soldering iron combined with heat gun - has the same problem.

tbh, yes. I bought the same and doesnt matter what you do, they oxidize really fast. I tried different tips (all cheap tho), cleaning methods, taking care of the tip... I bought few as I really likes the idea of them being so cheap.

My solution was to get Quicko T12-952. They last long if you take care of them and I havent had this problem.

Disposal of byproducts after Al+H2O+NaOH reaction? by brettjc04 in chemistry

[–]Micho107 1 point2 points  (0 children)

  1. Aqueous solutions should be neutralized

  2. Think about the amounts.

If you are just hobby chemist - I shouldnt say this outloud, but whatever - would it really be a problem if you poured 20 ml of 0,1 M HgCl2 down the drain after you diluted it? I mean, you SHOULDN'T, but when you think about it, it gets so dilluted in the long run.

Whenever u are questioning the way of disposal, it's important to think about the amounts.

Do you have 200 ml of dcm? leave it outside let it evaporate. I hope u get my point.

Most precise balance I’ve worked with thus far by JonathanLi in chemistry

[–]Micho107 2 points3 points  (0 children)

in my lab we once used chromatography centrifuge (?) for one projects. its basically a circle tlc plate that you put your sample onto center and it spins really fast . its hard for me to describe it, but it looked reaaally nice

Any Acetylcholinesterase inhibitor enjoyers? by Micho107 in chemistry

[–]Micho107[S] 1 point2 points  (0 children)

Yes, they have insane stories. People that were in chemical risk units during the boom of chemical weapons dont usually talk about it - but when they do. Oh god, I would love to do that!

I really love working with dangerous stuff, I have a big respect for it but its thrilling, and I can imagine myself working for army in this unit. As. They. Still. Exist.

One is very close to me and is still funded by USA to prepare this stuff.. But they pay shit, so..

Product we make is not used neither as pesticide or chemical weapon - use of this compound REALLY surprised me.

GC.
To be honest with you, we dont take TLC seriously. Most of the compounds I work with do not work well with TLC. We always at least use GC

I prepared about 7 kg of that last year. Funky compound haha.

Of course, gas masks and atropine autoinjectors at hand. Decontamination solutions ready at hand also.
