hydroflouric acid isn't toxic. it just goes through your skin like it's
not there, you can't feel it, and your bones dissolve (THAT is the
painful part).




Wrong. HF is considered a contact poison.


From http://www.sciencedirect.com/science...3646799290211B

"Hydrofluoric acid is a toxic substance used widely in both industrial and
domestic settings. It can cause severe burns, as well as systemic toxicity.
Death has been reported from as little as 2.5% body surface area (BSA) burn
involving concentrated acid. Topical and parenteral calcium salts have
proven effective therapy for both dermal and systemic manifestations. All
emergency physicians should be aware of the unique complications and
treatment of these injuries."

Information from other sources, including MSDS documents, is easily
available on the Web.
