Health hazards

toxic by inhalation, in contact with skin and if swallowed, causes burns. Note in this context, Hydrofluoric acid includes ammonium bifluoride. Hydrofluoric acid burns are a unique clinical entity. Dilute solutions deeply penetrate before dissociating, thus causing delayed injury and symptoms. Burns to the fingers and nail beds may leave the overlying nails intact. Severe burns occur after exposure of concentrated (i.e., 50% or stronger solution) Hydrofluoric acid to 1% or more body surface area (BSA), exposure to Hydrofluoric acid of any concentration to 5% or more BSA, or inhalation of Hydrofluoric acid fumes from a 60% or stronger solution. The vast majority of cases involve only small areas of exposure, usually on the digits. Solutions of less than 7% may take several hours before onset of symptoms, resulting in delayed presentation, deeper penetration of the undissociated HF acid, and a more severe burn. Pathophysiology: The 2 mechanisms that cause tissue damage are corrosive burn from the free hydrogen ions and chemical burn from tissue penetration of the fluoride ions. Fluoride ions penetrate and form insoluble salts with calcium and magnesium. Soluble salts also are formed with other cations but dissociate rapidly. Consequently, fluoride ions release, and further tissue destruction occurs. Mortality/Morbidity: Local effects include tissue destruction and necrosis. Burns may involve underlying bone. Systemic fluoride ion poisoning from severe burns is associated with hypocalcemia, hyperkalemia, hypomagnesemia, and sudden death. Deaths have been reported from concentrated acid burns to as little as 2.5% BSA.
