Guidelines for the Safe Use of Hydrofluoric Acid

Hydrofluoric acid etches glass, due to the strong bond formed between fluoride anions and the silicon molecules in glass. It will also react with glazes, enamels, pottery, concrete, rubber, leather, many metals (especially cast iron) and many organic compounds. Upon reaction with metals, hydrogen gas is generated that may pose an explosion hazard.
