Breathing hydrogen fluoride can damage lung tissue and cause swelling and fluid accumulation in the lungs (pulmonary edema). Skin contact with hydrogen fluoride may cause severe burns that develop after several hours and form skin ulcers.

Why does hydrofluoric acid dissolve glass?

Hydrofluoric acid does indeed dissolve glass very effectively, eventually leaving nothing of it left. The way this reaction works is based on the fact that fluorine has such a high electronegativity (the ability to attract electrons). Both of these reactions dissolve the silicon dioxide (glass) in the process.
