Hydrofluoric acid(HF) is a common laboratory reagents, but the dangers of HF, most laboratories do not exactly know, in fact, HF burns are very serious burns, and difficult to treat, so prevention paper and share laboratory HF burn treatment, we must remember to do experiments security, safety above all else!

Understand the nature of HF:

Hydrofluoric acid is a strong mineral acid and a strong dehydrating agent. An aqueous solution of hydrofluoric acid and anhydrous HF in appearance from colorless to pale colors. HF has a pungent odor. It is extremely corrosive.

Hydrofluoric health risks:

Hydrofluoric acid can not only cause burns, and fluoride ions can be rapidly absorbed through the skin. Then fluoride ions attack the subcutaneous tissue and is absorbed into the blood stream.

Liquid or gaseous HF can cause severe burns of the skin and deep tissues. If the eyes are exposed in HF, HF will penetrate into the internal organization.

Inhalation of high concentrations of HF can cause throat obstruction and acute pulmonary edema.

HF absorption of calcium due to HF fixed cause hypocalcemia. If severe hypocalcemia, hyperkalemia can occur.

HF burn area is larger than eight square inches of the people immediately sent to the intensive care unit, carefully monitoring 24-48 hours.

Any person who has been exposed to gaseous hydrofluoric acid and respiratory irritation have been also sent to the intensive care unit, careful monitoring. Blood sampling, monitoring the level of fluoride, potassium and calcium.
