With reference to the Case report on hydrofluoric acid (HF) vapor facial exposure (Journal of Chemical Health & Safety, January/February 2012; Sie´we´, et al., p 7) the first sentence of the Introduction is incorrect. Hydrofluoric acid is not "one of the strongest inorganic acids". It is, in fact, a weak acid. See any good basic chemistry text such as Chemistry, J. McMurry and R.C. Fay, Prentice Hall, ISBN 0-13-737776-2, p. 590-591, 1998.

The sentence would better be stated as "Hydrofluoric acid (HF), although a weak acid, is the most tissue-destructive of the inorganic acids, and "
