Wow - Muriatic Acid is some noxious stuff

[Sephire]

What kind of gloves do you need? What is it made of?

When I was a teenager I worked for a bottled water company. I would pour this into glass one gallon water bottles to dissolve the mineral and algae deposits that would form in them. Yeah, it's painful if inhaled.

Just rememberd this tidbit. From time to time some of it would spill onto the concrete floor. I would watch it as it bubbled and ate away at the concrete.

Weaker and it's eye drops.

thats nothing.

the scary stuff is the stuff that hits an unacceptable level before it reaches the point where you can even detect the odor, some paint strippers are that way.

looking at materials safety data sheet its nothing close to that for indirect stuff...

I work with that stuff every day... I clean pools. I've gotten a face full of fumes before and at first I'd try to tough it out... not any more! As soon as I get a face full I drop that jug in the pool and get the F&^* away!

I use my Gerber pocket knife to open the bottles, I have to replace the knife about every 6 months because it eats the tip of the knife away...

Yeah. We were working on my pool chlorinator (trichlor) one day and the workers said "you get used to the smell"

I got the fuck out and ordered them to do the same. That's chlorine gas boys. Gtfo. Now.

No ventilation. Super hot day. Gagging.

Don't you have a grinder to put a new edge on it?

Have you tried a titanium or ceramic knife?

Maybe passivating it would work.

Keeping it oiled might help.

Actually it's gaseous HCl. Chlorine gas is green in color and is heavier than air. Hence it's usage in trench warfare.

AAA rule of acids. When diluting, Always Add Acid to water, and never the other way around. When cleaning garage floors, you could use a much lower concentration than the stock 31% in the bottle. By diluting, you reduce the skin contact and inhalation hazards substantially.

For safety, keep a big box of baking soda around when using large quantities of muriatic acid to neutralize any spills. If you get some on your skin or eyes directly, wash with water for 15min or so. Washing past 15min (really more like 5min) is just going to cause hypothermia. If you get it absorbed into your clothing, don't be bashful and strip the clothes off immediately. If you're working with it in enclosed spaces, you should be fitted for and trained in the usage of a full face respirator. At very high concentrations in enclosed spaces, I would assume SCBA and a full HAZMAT suit would be necessary.

2HCl + NaClO --> Cl2 + NaCl + H2O

I think the concentration needs to be fairly high before it looks green in the air. It's still dangerous in concentrations you can't see.

I thought the gas they used was mustard gas? That's brown, isn't it...?

Mustard gas became the standard, but they did use pure chlorine at first.
