Although hydrofluoric acid is not strong acid, but it is dangerous, high-corrosion properties of human skin constitute injury, inhalation of hydrofluoric acid vapors emitted can cause pulmonary edema, and HF vapor is dissolved in a liquid eye. 

Hydrofluoric acid has not been reported to be a human carcinogen. No acceptable animal test reports are available to define the developmental or reproductive toxicity of HF. The OSHA Permissible Exposure Limit is 3 ppm (as fluoride). Anhydrous HF has a vapor pressure of 775 mm Hg at 20℃, while Hydrofluoric acid has a vapor pressure of 14 mm Hg at 20℃.

HF attacks glass, concrete, and many metals. It also attacks carbonaceous natural material such as woody materials, leather, and rubber.

Some materials resist the corrosive action of the acid, such as platinum, wax, polypropylene, polyethylene, and Teflon. In contact with metals with which it will react, hydrogen gas is liberated and the danger exists of a spark or flame resulting in an explosion. HF is used in many labs and in the glass shop on a regular basis. It should always be stored in plastic bottles. Containers of HF should be stored in secondary containers made of polyethylene in areas separate from incompatible materials. All work with hydrofluoric acid should be conducted in a fume hood to prevent exposure by inhalation. Splash goggles and Neoprene gloves as well as laboratory coats should be worn at all times to prevent eye and skin contact.

It would cause lasting damage to human vision. In vitro exposure to very dilute HF can cause severe burns outside. When burns white skin, under the skin tissue is damaged, the damage will even spread to the bone.

Experts remind that skin contact with HF should be thoroughly washed with cold water until the whitish situation disappears, then apply three ounces of magnesium oxide, 4 ounces heavy cream coated with oil and 11 ounces of white petrolatum, and in contact with hydrofluoric after the acid or its vapors should seek medical treatment as soon as possible.
