Hydrofluoric acid (HF) is a highly corrosive inorganic acid. HF must be handled with extreme caution because it can penetrate the skin extremely easily and decalcifies bones leading to tissue necrosis, which may result in amputation and death. Severity and rapidity of onset of signs and symptoms depends on the route of exposure, concentration of the acid, duration of exposure, and the penetrability of the exposed tissue. In case of exposure emergency procedures should be instituted IMMEDIATELY and whenever there is any reason to suspect exposure to the chemical.
The Hydrofluoric Acid Safety Document outlines the correct procdures and methods to use when handling, storing, or disposing of HF, as well as the dangers and management of accidents.
