Hydrofluoric acid injuries have a potential for both systemic as well as severe local tissue destruction. In this article the different treatment modalities will be presented. Hydrofluoric acid is frequently found in the semiconductor industry, in rust removers and façade cleansers. The negligence or carelessness of workers and ignorance of the risks of hydrofluoric acid promote the incidence of these severe burns. To prevent these burns, adequate information for the workers is necessary. Splash goggles and neoprene gloves as well as laboratory coats should be worn at all times to prevent eye and skin contact. In cases of exposure, therapy should be accurate and immediate.
