Which could impair an individual's ability to take Irreversible or other serious health effects or symptoms Which it is believed that nearly all individuals could beĮxposed for up to 1 hour without experiencing or developing Planning guideline) (maximum airborne concentration below Standards and Guidelinesģ ppm (averaged over an 8 hour work shift) Rust removers (e.g., for ceramic tubs, sinks, and fabrics),Īnd water-spot removers. Products (e.g., for aluminum and chrome), rust inhibitors, Some consumer products that mayĬontain hydrogen fluoride include automotive cleaning It also is used in manufacturing silicon semiconductor chipsĪnd as a laboratory reagent. Hydrogenįluoride is used in separating uranium isotopes, as aĬracking catalyst in oil refineries, and for etching glassĪnd enamel, removing rust, and cleaning brass and crystal. It is produced commercially byĪction of sulfuric acid on the mineral fluorspar. Hydrofluoric acid is likely to produce systemic effects and Relatively larger surface area:body weight ratio. Toxicants absorbed through the skin because of their Hydrogenįluoride is irritating to the skin, eyes, and mucous Ion, which penetrates tissues deeply, can cause both localĬellular destruction and systemic toxicity and is readilyĪbsorbed through both intact and damaged skin. Skin/Eye Contactīy cutaneous contact with the aqueous solution. The relatively smaller diameter of their airways. More vulnerable to corrosive agents than adults because of They have greater lung surface area:body weight ratios and Hydrogen fluoride as adults may receive larger doses because Therefore, odor generally provides adequate Of about 0.04 ppm, which is considerably less than the OSHA Strong irritating odor that is discernable at concentrations Even fairly low airborneĬoncentrations of hydrogen fluoride produce rapid onset ofĮye, nose, and throat irritation. Hydrogenįluoride gas is lighter than air. Routes of Exposure InhalationĮxposure to hydrogen fluoride gas, but also from fumesĪrising from concentrated hydrogen fluoride liquid. TheseĮffects are due to the fluoride ion's aggressive,ĭestructive penetration of tissues. Serious health effects by any route of exposure. Variety of over-the-counter products at concentrations of 6%Ĭompared with most other mineral acids, it can produce Hydrogen fluoride readily dissolves in water to formĬolorless hydrofluoric acid solutions dilute solutions are Usually shipped in steel cylinders as a compressed gas. Most hydrogen fluoride exposures occur by inhalation of the gas and dermal contact with hydrofluoric acid.įuming liquid or gas with a strong, irritating odor.The surface area of the burn is not predictive of its effects. Its severe and sometimes delayed health effects are due to deep tissue penetration by the fluoride ion. Hydrofluoric acid is a serious systemic poison.Victims exposed only to hydrogen fluoride vapor do not pose substantial risks of secondary contamination however, victims whose clothing or skin is contaminated with hydrogen fluoride liquid or solution can secondarily contaminate response personnel by direct contact or through off-gassing vapor.UN# 1052 (anhydrous), 1790 (solution) PDF Version pdf icon įluoric acid, hydrofluoride, hydrofluoric acid, and fluorine monohydride.
