Commercially, HF is used in glass etching, electroplating, and semiconductor manufacturing. Consumer products are typically marketed as rust removers and chrome cleaners. Although toxic via the dermal, ocular, pulmonary, and GI routes, most patients present after dermal exposure, typically to the hands and fingers. The severity of local injury depends on the HF concentration and the extent of exposure.
