Requirements for Use of Hydrogen Fluoride Gas and Hydrofluoric Acid

General Description

Hydrogen Fluoride (HF) is a colorless fuming gas or liquid. In its liquid state it’s called Hydrofluoric Acid. Acute and chronic exposure to both gaseous and liquid HF can have very serious and life threatening health effects. HF will penetrate the skin and attack the underlying tissues and bone, possibly with fatal results. The full extent of damage may not exhibit itself until hours after the exposure. Therefore, all laboratory personnel who work with Hydrogen Fluoride gas or Hydrofluoric Acid must implement the procedures and laboratory design requirements shown below.
