A hydrofluoric acid burn is a chemical burn from hydrofluoric acid.[1] Where it contacts the skin it results in significant pain, swelling, redness, and skin breakdown.[1][2] If the fumes are breathed in swelling of the upper airway and bleeding may occur.[2] Complications can include electrolyte, heart, lung, kidney, and neurological problems.[1][2]
Most exposures occur at work.[2] With concentrations less than 7%, onset of symptoms may not occur for hours while with concentrations greater than 15% onset of symptoms is nearly immediate.[1] Diagnosis should include blood tests for calcium, potassium, and magnesium along with an electrocardiogram.[1]
Initial treatment of exposure involves removing contaminated clothing and washing with large amounts of water over at least 30 minutes.[1] Other measures include applying calcium gluconate cream.[1] It is estimated that about a thousand cases occur each year globally.[1] Most people affected are adult males.[1]
