( Hydrofluoric acid) - A colorless, liquid. Used to polish, etch and frost glass, also used in the production of aluminum, brass, stainless and other alloy steels. Hazard: Highly corrosive to skin and mucous membranes. Highly toxic to by ingestion and inhalation.

a colorless poisonous corrosive liquid made by the action of sulphuric acid on calcium fluoride; solutions in water are hydrofluoric acid

chemical formula HF, hydrogen fluoride is a toxic, corrosive gas with a TLV of 3ppm. Hydrogen fluoride has a sharp irritating odor and is irritating to lungs, skin and eyes. Hydrogen bromide is used to generate hydrofluoric acid.

Hydrogen fluoride is a chemical compound with the formula HF. It is the only fluoride of hydrogen. HF boils just below room temperature whereas the other hydrogen halides condense at much lower temperatures.
