What Is Hydrofluoric Acid Used For?

How long does hydrofluoric acid kill?

What neutralizes hydrofluoric acid?

You can neutralize small spills (100 mL or less) by covering with magnesium sulfate (dry) and absorbing with spill control pads or other absorbent materials. Add sodium bicarbonate or magnesium oxide to any absorbent and place in a plastic container for disposal. Wash the spill site with a sodium bicarbonate solution.

Can hydrofluoric acid harm you?
