thank you very much. safety is SO important and so often overlooked. the time to be safe, to be prepared, is BEFORE you need to be. great point about possibly not being able to see your way to the sink. subbed.

@XDecagraphX Well, I think you need one more tip. Whenever you do home chemistry, check the MSDS of any chemical you use. Another point, make sure any reaction you do is safe. The Internet is a wonderful tool and is also extremely useful for all home scientists.

Nice video. I think safety is something that goes unmentioned in too many of the scientific youtube videos. My first line of defense is prevention through good practices and the equipment is secondary. Thanks for sharing.

Great video! Love how you explain everything, and go the extra mile to really make sure that the viewers gets it.

Arrange First Aid Kit opened in a drawer so that if working by self and injure your hand you can open drawer with little effort to get access to first aid supplies. Very cool video course.

Very good videos, been enjoying them, thanks. Have had a home lab since i was 9-10 years old. Great stuff. One thing. When demonstrating a procedure for rinsing, you don't need to use the actual chemical. Use a substitute, and make aware that it is a substitute. In this case, it could give the impression that HCI is not dangerous.

your voice is great. please keep making videos, they are fantastic.

Great video..... SAFETY FIRST love that you touched on this

okay, thanks for the explanation! you are so calm answering people question.

This video is several orders of magnitude better then the out dated lab safety video they show students at my university...

@TheHomeScientist Thanks, Robert. I'll keep a tub of washing soda on hand then. So far, I've fitted my lab with sand (for fires, as well as for differential solubility lab) and baking soda. To be effective in an emergency situation, the sand would have to be kept probably right on the lab bench, close to wet area. I may just go for an ABC extinguisher anyway, to have for the general area anyway (garage).

Outstanding advice! Mr. Thompson has been at this sooooo long, he just knows the MSDS for all these chemicals by memory. For noobs like me... this is where I should start. :P

You are great. And i specially liked because you pureed acid on your hand. Not that i wanted something happen to you.

Hydrochloride acid takes A LOT longer to sting your hand, about 45 seconds, just watch Nile reds video pouring acids on my hand

great video.

Shouldn't a bottle of vinegar be a part of the safety setup in addition to the baking soda, to neutralize bases? I myself have hade many more incidents with bases (mostly NaOH) than acids and have been ever so thankful for the bottle of vinegar I keep under the sink :)

Just dont use them when working with ethers,esters,acetone,ozone or High intensity UV (mainly UVC lamps). Really the glove choice depends on working with, just check the material ratings.

Whats the best thing to do if you get a small spill of conc. HF on your Hand?

Do you know if they make a Class ABCD extinguisher? That would cover any possible flammable metal fires the ABC extinguishers can't handle. I went to two big box stores yesterday (Hoes and HD) but could only find Class ABC.

@TheHomeScientist Thanks, ive also heard of Ca-Gluconate injection. Anyway, to be honest, i know the danger oft HF. My question in meaning "small spill" was, if it´s acutally enough to wash your hands only with water, if the spill is smaler than the size of a match -head. ;-)

would it be wise to try to neutralize acid in your eye with baking soda?

btw, can carbon dioxide fire extinguisher put out all type of fire?

@XDecagraphX It wouldn't have *osmosed* through skin.

What if you were to get concentrated sulfuric acid which "sucks" water out of your hands

I was going to say that I always thought H2SO4 was the strongest. But I believe you. It has been a long time since I did my A levels.hahaha

@Aev308 Wear a face shield, then.

@barhamd Well, the demo seems to work but personally I just wouldn't trust it.
