Even then, you can only work with it in teams of at least 2, all being certified to work with HF, only during normal business hours, and with a safety checklist a mile long, which includes checking to see that the calcium gluconate in the emergency kit is unopened and unexpired, and there are extra gloves with it, so the person applying it to you does not also get poisoned just by touching you.
That reminds me of why I decided against buying a portable sawmill. The nice ones come with an amputation kit, so when you cut something off accidentally there's a tourniquet on hand to slow the bleeding.
This comment is misinformed and should be deleted because it is so dangerous. HF will kill you for looking at it in the wrong way; please don't handle it unless you understand the danger it poses to you and the people around you.
Why is this comment misinformed? In a video tour of his home lab, Sam Zeloof shows us his acid-storage cabinet and mentions that he gets HF from over-the-counter Whink-brand "Rust Stain Remover"[1].
Since this product is commonly available at hardware stores across the United States, why should comments related to it "be deleted because it is so dangerous"?
I agree that HF can be extremely dangerous, but in this case it's not clear that Sam is working with or advocating use of dangerous concentrations or chemcial forumulations of fluorine-based acids. Maybe I missed a post where he does discuss using more dangerous concentrations or compounds?
I hope your "water gun" is made entirely of polypropylene, neoprene, polytetrafluoroethane, polyvinyl fluoride, wax, lead, and/or polyethylene.
And that you're wearing a chemical protection suit with respirator while playing with it. And that you are well aware of wind and weather conditions. And that you take care to keep it out of the environment.
Seems like one of those things that would be more dangerous to the wielder than anyone else.
