Hydrofluoric acid (HF) is an aqueous solution of hydrogen fluoride. It is widely used in glass etching, cleaning semiconductor etching, electro polishing, cleaning external walls of buildings and other industries, are also often used in the production of sodium fluosilicate, hydrofluoric acid ammonium for packaging and transportation of salts. But these mediators in the use of the process in the presence of hydrofluoric acid, its security problem easily because of its form, or the name change was ignored by the users. 

Through the years, a concentrated effort has been made to understand the effects of many variables on hydrochloric acid spending in limestone. Hendrickson et al., have given mathematical relationships for HC1 reactions which made possible the engineered approach to acidizing. The same variables-temperature, acid concentration, formation composition, pressure and permeability-porosity relationships-which affect HC1 behavior in limestone also govern HF behavior in sandstone. Insoluble byproducts of HF reaction have been isolated and identified. Their effect on fluid flow has been measured under varying conditions in an attempt to evaluate the extent of possible damage and means of eliminating it. In general, HF follows the same reaction paths as HC1. It will react with limestone and dolomite with speed and ease. Thin sections of acidized cores show the reaction of HF with limestone or calcite faster than its reaction with either clay or sand. When HF reacts with calcite (CaCO3), theoretically, calcium fluoride (CaF2) is precipitated, and has been blamed as a major cause of reduced permeability. On the other hand, pH and pressure such as that encountered in an underground formation under acid treatment definitely retard CaF2 formation, so the whole question of CaF2 deposition in wells is a subject for study.

From the physical and chemical properties and uses of hydrofluoric acid and its derivatives described in use, storage and other aspects of security issues and to increase the user's capability of independent door, reduce accident and environmental issues.
