A hydrofluoric acid burn is a chemical burn from hydrofluoric acid. [1] Where it contacts the skin it results in significant pain, swelling, redness, and skin breakdown. [1] [2] If the fumes are breathed in swelling of the upper airway and bleeding may occur. [2] Complications can include electrolyte, heart, lung, kidney, and neurological ...
Other sources include glass-etching or chrome-cleaning agents like ammonium bifluoride or hydrofluoric acid, [12] [13] industrial exposure to fluxes used to promote the flow of a molten metal on a solid surface, volcanic ejecta (for example, in cattle grazing after an 1845–1846 eruption of Hekla and the 1783–1784 flood basalt eruption of ...
Although hydrofluoric acid is regarded as a weak acid, it is very corrosive, even attacking glass when hydrated. [ 20 ] Dilute solutions are weakly acidic with an acid ionization constant K a = 6.6 × 10 −4 (or p K a = 3.18 ), [ 10 ] in contrast to corresponding solutions of the other hydrogen halides, which are strong acids ( p K a < 0 ).
Hydrofluoric acid, the water solution of hydrogen fluoride (HF), is a contact poison. Even though it is from a chemical perspective a relatively weak acid, it is far more dangerous than conventional strong mineral acids, such as nitric acid, sulfuric acid, or hydrochloric acid. Owing to its lesser chemical dissociation in water (remaining a ...
Symptoms include itching, bleaching or darkening of skin, burning sensations, trouble breathing, coughing blood and/or tissue necrosis. Common sources of chemical burns include sulfuric acid (H 2 SO 4), hydrochloric acid (HCl), sodium hydroxide (NaOH), lime (CaO), silver nitrate (AgNO 3), and hydrogen peroxide (H 2 O 2). Effects depend on the ...
Torrance resident Isabel Douvan Schwartz said she worries about a major earthquake hitting her community, largely because of the impact it could have on the massive Torrance Refinery two miles ...
Common agents include: sulfuric acid as found in toilet cleaners, sodium hypochlorite as found in bleach, and halogenated hydrocarbons as found in paint remover, among others. [2] Hydrofluoric acid can cause particularly deep burns that may not become symptomatic until some time after exposure. [37]
These hormones regulate calcium concentration in the body. An elevated parathyroid hormone concentration results in a depletion of calcium in bone structures and thus a higher calcium concentration in the blood. The clinical symptoms of fluoride toxicity in the bones are indistinguishable from arthritis.
