Hydrofluoric acid 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.

Hydrofluoric acid, solution is a colorless fuming mobile aqueous solution with a pungent odor. Corrosive to metals and tissue. Highly toxic by ingestion and inhalation. Exposure to fumes or very short contact with liquid may cause severe painful burns; penetrates skin to cause deep-seated ulceration that may lead to gangrene.

Hydrofluoric acid is stimulating to clothing, eye, respiratory, gastrointestinal mucosa, and has corrosion, fluorine ions into the blood or tissue can combine with calcium and magnesium ions, making it insoluble or sparingly soluble calcium fluoride and magnesium fluoride, it can direct clogged blood vessels if with a large amount. Directly or indirectly affect the function of the central nervous system and cardiovascular system, resulting in hypocalcemia, hypomagnesemia syndrome, fluoride ions can also be combined to form a fluorine-hemoglobin and hemoglobin, inhibition of succinate dehydrogenase and oxygenation to decline, has effect on cells respiratory function.
