Earlier days people used sulfuric acid to remove tattoos. On inner arm, face or on the softer skin on the body, it will slowly burn through the skin layers and make permanent scars
I think its more important to use goggles when working with acids. Its hard to wash ur eyes without special eyewashing station in case of acid getting in em.
I think it would have been better if you had showed the after care. Like, yeah, if you rinse off immediately, try to neutralize, etc. then there's no permanent damage. IMO, your point is still vaild.
Yeah, 98% sulfuric acid at room temperature is not that bad on the skin of your hands if you wash it off fast, it will take a minute or so to just cause irritation and pain, several minutes to give you a burn. Not only because of protection by moisture on the skin, but also due to the dead skin layer that will momentarily stop it from getting in the underneath live tissue. It will give you a chemical burn if you let it sit for a while though. Also it's much nastier in the skin of your face (which is less thick and therefore less resistant) and it can cause permanent damage very fast if it gets in the eyes (as we can witness from cases of acid attacks). If ingested it will burn your mouth and esophagus in a matter of seconds and even as little as 10 ml can be fatal orally. Sulfuric acid vapor will kill you in subgram quantities if inhaled, by disrupting the blood-air barrier in the alveoli of the lungs and causing pulmonary edema. Sulfuric acid at high temperatures (and/or pressures) is a whole different beast even on the skin of your hands though; boiling sulfuric acid will instantly char your skin leaving a black mass of carbon in its place. I still would reccomend wearing gloves even with room temperature concentrated sulfuric acid as it is good laboratory practice and even if some sulfuric acid won't harm you on your bare skin, gloves will offer some more level of protection and prevent some discomfort. I'm not gonna be a safety nazi though by trying to force people who are clearly experienced and know what they are doing into doing the same as me. I usually do wear latex gloves when handling sulfuric acid as I have naturally a very dry skin and sulfuric acid will only make it worse. But as always the best protection is to not spill hazardous chemicals in the first place. Also using gloves can even be more dangerous than not using them if they are not used in the proper manner. Gloves won't make you invincible, a lot of stuff will easily pass through them if they are not chemically compatible, (let's remember that Karen Watterhan did have gloves) and in case of a spill if the substance being handled is a particularly dangerous one you are supposed to change them as soon as possible and not to just sit there for hours with contaminated gloves. Some substances like fuming nitric acid can even react violently with nitrile/latex gloves and in this case butyl or isoprene are reccomended instead. Also if a chemical representing an acute inhalation danger is handled in a closed ampoule, wearing gloves can increase risk by diminishing the grip.
Agree. In this video, my partner pours 95% nitric acid on my finger and a latex glove to check which one survives: th-cam.com/video/NHBDXtn7pjA/w-d-xo.html
Many years ago I found a battery pack for a real time clock in a computer. It was very old and packaged in a plastic wrap of some kind. I was curious about the cells inside and being stupid tore the package open with my teeth. Some alkaline? dropped on my lip and it burned within a fraction of a second. I was only 5 seconds away from the bathroom sink by which time it had eaten a piece of my lip about the size of 1/4 of a pea. The burn was very painful and the lip took many many months to fully heal. I think the cells were just common Alkaline cells. Had the alkaline become super concentrated through drying out?
I distilled drain cleaner yesterday and the real problem is sulfur trioxide. I didn't use teflon tape to seal my distillation setup so a lot of SO3 vapours leaked and inhaling them is not pleasant. Getting sulfuric acid drops on my skin was not a big problem. I recently tried to concentrate hydrogen peroxide and I would say that concentrated sulfuric acid drops are harmless when compared to drops of concentrated hydrogen peroxide. Even laughably small drops of H2O2 will quickly turn your skin white.
I seen the other comment and thought would check this out. Nice vid. So how quick do you need to wash your hands? Is it kind of like putting your finger in a candle flame?
It only matters if it's hot. I regularly use concentrated sulfuric acid and fuming nitric acid without gloves. It's actually better not to wear them around RFNA/WFNA.
I totally agree. In this video, my partner purposely pours 95% nitric acid on my finger and a latex glove to see which of the two survives: th-cam.com/video/NHBDXtn7pjA/w-d-xo.html
When it's boiling (at 337°C) it makes no difference if you have gloves or not, it will instantly make a hole all the way through your hand and char everything along its path.
I dislike that in it's incompleteness, the video may leave the naive viewer (particularly kids) with the false impression that skin contact with the acid is somehow entirely harmless, when in fact, one has mere tens of seconds at most to thoroughly wash off or neutralize the acid. An acid attack recently took place again in Malaysia, severely burning a football player there. Where his scalp was completely burned away, his skull is visible. I'm not criticizing your choice to wear, or not wear gloves, do as you wish. But the inescapable fact that one has mere seconds to wash off concentrated sulfuric acid from the skin if they wish to escape severe burns and permanent life-altering disfigurement must be emphatically stated clearly.
The video is about having sulfuric acid on your HANDS, not on your face or on your scalp. It doesn't call for using it as eye drops or drinking it either.
@@Muonium1 Well, to be honest, it is your comment that is irrelevant and pointless. The video that you are criticizing discusses about the fact that having sulfuric acid on the hands is not terrible, and you switched the subject to discussing having acid on the face and the skull. This is what is totally irrelevant. The author, to my knowledge, never claimed that it is okay to have this acid on the face or on the skull.
Mic drop.
Glad I found your excellent channel.
Thanks!

I spilled 30 volume (9%) H2O2 on my hands recently and the damage to my skin was apparent in a few seconds.

I usually go rinse the affected area within 2 minutes. That leaves plenty of time. Marks, if any, are totally gone within two days.
Bravo!
I always wear gloves when working with any substance. Makes it easier to wash the glassware if there is no grease on top
That's a good reason for wearing gloves. But I personally am more clumsy when I wear gloves, my touch sense is completely messed up.
Thanku for your great❤ videos.
You're welcome. Please, share them on your social networks.

You should watch NileRed’s video where he intentionally spills various acids on his skin until they begin to hurt. The worst one was nitric.
I do it with nitric acid in this video: th-cam.com/video/NHBDXtn7pjA/w-d-xo.html
i think they meant when it is boiling
:))

@@lagrangiankid378
Exactly!
Well, the sulfuric acid in my experiment that they criticized was at room temperature.
😂😂😂😂lol
Is 93% sulfuric acid more dangerous on your skin because I’ve gotten burns after just 20 seconds on my arm with 93%
It wasn’t a very bad burn but you talk about leaving 98% on your finger for 2 minutes in one of the other comments
I do agree that it’s certainly not a problem if rinsed off immediately
The skin on the arm is much thinner than the hands.
