HF burns, not evident until a day after Symptoms of HF exposure include irritation of the eyes, skin, nose, and throat, eye and skin burns, and bone damage. Complications may occur due to fluoride toxicity. Once absorbed into blood through the skin, it reacts with blood calcium and may cause cardiac arrest. Burns with areas larger than 160 cm2 (25 square inches) have the potential to cause serious systemic toxicity from interference with blood and tissue calcium levels. In some cases, exposures can lead to hypocalcemia. Breathing in the HF fumes can result in fevers, pulmonary edema (fluid buildup in the lungs), bleeding, and low blood oxygen.
