Working with hydrofluoric acid | Department of Mines, Industry
Hydrofluoric acid is very corrosive, highly irritating and poisonous. Hydrofluoric acid burns can be severe and extremely painful, causing extensive damage or even death. Uses Some uses and sources of hydrofluoric acid (also known as HF) include: Aluminium cleaner and brightener Oil refineries (alkylation process)
Handling & storage of hydrofluoric acid (HF)
Hydrofluoric acid is corrosive and highly toxic. It quickly penetrates into the skin, destroys deeper layers of tissue, binds cations and can lead to acute metabolic disorders and impaired kidney function by inhibiting vital enzymes. Contact on a surface area as small as the palm of a hand can lead to cardiovascular breakdown and death.
