Huh, funny. I work with chemicals that turn into hydroflouric acid when they touch atmosphere. It's extremely corrosive. It also has the fun property of not only burning your skin, but absorbing into it and de-calcifying your bones! Not that it is pertinent information, but the treatment for an HF burn is calcium gluconate. It might be a worthwhile thing to have in your first aid kit if there is any belief you are at risk of exposure.
