When use hydrofluoric acid you must wear rubber gloves and gas masks, it cannot be fitted in glass bottles, it is better to fit in PTFE bottle. In order to prevent more mild hydrofluoric acid spill hurt yourself, put some lime and plenty of water beside you. The safest approach is to avoid the use of hydrofluoric acid.

Currently, used for producing an electronic grade hydrofluoric acid purification technology at home and abroad have distillation, distillation, sub-boiling distillation, vacuum distillation, gas absorption technology, these purification technologies have their own characteristics, their own merits. Such as sub-boiling distillation technique can only be used to prepare a small amount of product, gas absorption technology for large-scale production. Further, since the highly corrosive hydrofluoric acid, the use of corrosion at high temperature distillation process will be more serious, so the distillation apparatus used is generally required platinum, gold, silver and other precious metals such as polytetrafluoroethylene or corrosion resistance capacity than strong material to make.

Hydrofluoric acid (HF) produces a unique chemical burn due to tissue penetration by fluoride ion. Fluoride ion interferes with calcium activity in a variety of cell membranes and calcium-dependent processes, resulting in severe pain and deep tissue destruction. The currently accepted methods of treating HF burns include application of topical soaks or ointments with calcium or magnesium salts for minor burns and local injection of calcium gluconate for more severe burns. Digital burns also may require nail removal and direct injection into the nail bed. We present the cases of a series of patients with moderate to severe HF burns involving one or more fingers who were treated with selective intraarterial calcium infusion of dilute (1.66%) calcium salts. All patients had excellent relief of symptoms and marked improvement of the burn lesions following one of three four-hour infusions of calcium chloride or calcium gluconate.
