WebWeak acid, as you say, just means that the acid does not readily dissociate, not that its effects are weak! Just to say one, HF corrodes glass, something that not even smoking HCl does. Wikipedia has a nice summary of HF toxicity (see also the references in the article itself): Hydrofluoric acid is a highly corrosive liquid and is a contact poison.
