Hydrogen fluoride is used in the production of aluminum and chlorofluorocarbons, and in the glass etching and chemical industries.
Acute (short-term) inhalation exposure to gaseous hydrogen fluoride can cause severe respiratory damage in humans, including severe
irritation and pulmonary edema. Severe ocular irritation and dermal burns may occur following eye or skin exposure in humans.
Chronic (long-term) exposure of humans to fluoride at low levels has a beneficial effect of dental cavity prevention and may also
be useful for the treatment of osteoporosis. Exposure to higher levels of fluoride through drinking water may cause dental fluorosis
or mottling, while very high exposures through drinking water or air can result in skeletal fluorosis in humans. The only developmental
effect observed from fluoride exposure in humans is dental fluorosis which can occur in a child’s teeth when a mother receives high
levels of fluoride during pregnancy. EPA has not classified hydrogen fluoride for carcinogenicity.
Hydrogen fluoride, anhydrous is a colorless fuming liquid boiling at 67°F. Shipped as a liquid confined under its own vapor pressure.
Corrosive to metals and tissue. Very short contact with fumes or small quantities of the liquid can cause severe, painful burns.
Vapors are heavier than air. Density 8.2 lb / gal. Used as a catalyst and raw material in chemical manufacture.
Rate of onset: Immediate & Delayed Persistence: Minutes to hours Odor threshold: 0.4 ppm Source/use/other hazard: Aluminum and
other metal industries; insecticide manufacturing-corrosive liq.

Stability and Reactivity of HYDROFLUORIC ACID 38-40 % :
Chemical Stability: Normally stable.
Conditions to Avoid: Incompatible materials, metals, high temperatures.
Incompatibilities with Other Materials: Substance is incompatible with over 35 specific chemicals. Please refer to the NFPA Fire Protection Guide
for specifics. Heat. Glass, concrete and other silicon-bearing materials will yield silicon tetrafluoride. Pressure build-up from this process has been
known to blow up glass containers. Carbonates, sulphides, and cyanides will yield toxic gases such as carbon dioxide, hydrogen sulphide and
hydrogen cyanide. Alkalis, some oxides, fluorine and other water-reactive materials will cause strong exothermic reactions that can be violent.
Reacts with most common metals to produce hydrogen. Corrosive to many materials, including leather, rubber and many organics.
Hazardous Decomposition Products: Fluoride fumes.
Hazardous Polymerization: Tends to associate by means of hydrogen bonds to form polymers in both liquid and gaseous states. This
polymerization is not hazardous.

Hydrogen fluoride is used in the glass etching, electronic, and chemical industries.
Hydrogen fluoride is predominantly used in the production of aluminum and chlorofluorocarbons (CFCs). Hydrogen fluoride is also used for separating uranium isotopes, as a catalyst in the petroleum industry, and in stainless steel pickling.
Fluoride is sometimes added to public drinking water supplies, and is used in a number of dental products.
