What is hydrogen fluoride?
Hydrogen fluoride (HF) is a colorless gas or liquid that is made up of a hydrogen atom and a fluorine atom. It creates strong fumes, readily dissolves in water, and both the liquid and gas will cause severe burns upon contact. The liquid form is called hydrofluoric acid. Commercially, HF is used in the manufacture of fluorocarbons, which are used as refrigerants, solvents and aerosols. Low levels of sodium fluoride are found in products such as toothpaste and water. Sodium fluoride is different than hydrogen fluoride. A concentrated release of hydrogen fluoride can cause harm. How can someone come into contact with hydrogen fluoride? Exposure to small amounts of fluoride can occur by breathing air, drinking water, eating food or using some other products that contain fluoride. Fluoride in low amounts will not harm people, and may actually have health benefits such as preventing tooth decay.
