ABSTRACT
Hydrofluoric acid, one of the strongest inorganic acids known (1), has been in industrial use since its ability to dissolve silica was recognized in the late 17th century. Hydrofluoric acid has a number of chemical and indus trial applications. In 1976, the National Institute of Occu pational Safety and Health listed 57 occupations with an estimated 22,000 workers who had potential exposure to hydrofluoric acid on a daily basis (Table 28-1) (2-4).
