Just purchased this stuff a week or two ago and am glad to have seen this thread. I was unaware this stuff was a hydrofluoric analogue.

I'm a chemist in a research lab. We work with lots of nasty stuff including liquid HCN (HCN salts used in gas chambers in WW2) which can kill you with a single drop. To this day, about the only chemical we refuse to work with is HF. It's an excellent digestive agent for metals analysis, but the risks aren't worth the advantages over alternatives.

When working with the glacial acids (as in the fatility story - way more concentrated than etch-all! - hate scare stories...) the fumes are potentially deadly and a drop will eat through your jeans in seconds. The problem with HF is how easily it penetrates through clothing and skin. Even with these relatively dilute solutions please be very very careful to avoid contact and treat all spills properly. Pretend it's another torch flame...

The good news is nitrile gloves seem fairly resistive to degradation and permeation but be aware that chemist use thicker gloves and don't buy them from the dollar store. Sunlight and heat may compromise your gloves.

gloves, chemical apron, goggles, sleeves, face shield, and good ventilation are highly recommended.
