Hydrofluoric acid (HF)
Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water. Solutions of HF are colorless, acidic and highly corrosive. It is used to make most fluorine-containing compounds; examples include the commonly used pharmaceutical antidepressant medication fluoxetine (Prozac) and the material PTFE (Teflon). Elemental fluorine is produced from it. It is commonly used to etch glass and silicon wafers.

1) Sealed packaging and stored in a cool, dry, and well ventilated dedicated warehouse. The temperature of the warehouse should not exceed 30 ºC.
2) To prevent sudden explosions, the storage time should not be too long, and attention should be paid to adding stabilizers.
3) A cofferdam is set up in the hydrofluoric acid storage area, and the ground is subjected to anti permeability treatment, and inverted tanks or liquid storage tanks are equipped. The storage area should be equipped with suitable materials to contain leaks.
4) It should be stored separately from combustibles and edible chemicals, and mixed storage should be avoided.
5) Regularly inspect the storage tanks, tank trucks, valves, and pumps of hydrofluoric acid to prevent leakage.
