Too right
HF is horrible stuff. The reaction with bones is catalytic, too, so once it starts it just keeps going. If you get splashed and don't deal with it at once, the ONLY treatment is amputation at the next major joint up, On your finger, lose your hand. On your wrist, lose your forearm.

I used to use it in a cocktail for etching niobium superconductors. It is the only thing I have ever used at work which seriously terrified me.
