[26] Symptoms of HF exposure include irritation of the eyes, skin, nose, and throat, eye and skin burns, rhinitis, bronchitis, pulmonary edema (fluid buildup in the lungs), and bone damage.[27]. Use of hydrofluoric Using hydrofluoric acid in the workplace Hydrofluoric acid (HF) is a corrosive and toxic acid that can cause serious burns and even death. The full-strength hydrofluoric acid is used in the construction and manufacturing of high-octane fuels in oil refineries. Anything that touches contaminated clothing should also be placed in the bag. Due to its strong The seriousness of poisoning caused by hydrogen fluoride depends on the amount, route, and length of time of exposure, as well as the age and preexisting medical condition of the person exposed.
