Hydrofluoric Acid burn prevention
Hydrofluoric acid is one of the most hazardous chemicals to human health because of its aggressive characteristics. It is a double action chemical; both corrosive and toxic: A corrosive property on the surface due to the free hydrogen ions and a toxic property due to the penetration of the fluoride ions. It is one of the strongest inorganic acids and is most commonly used in many industrial and domestic settings. Hydrofluoric Acid was first used for glass etching due to its corrosive properties, but currently is also widely used in metal cleaning, the semiconductor industry, manufacturing fertilizer, pesticides, some plastics, and at home in cleaning agents and rust removers. HF is considered a contact-poison with the potential for deep, initially painless burns followed by tissue death.
As the aggressive chemical penetrates deeply before dissociation, a delay of injury, pain and symptoms occur. It is often found that burns to the fingers and nail beds leave the overlying nail intact. It is for this reason that HF burns are a unique clinical entity, as little surface abnormality is shown following a splash, as well as the ability of this solution to cause significant systemic toxicity. The two mechanisms responsible for this extensive damage are the corrosive burn from the H+ ions (acid) and the toxicity of the F- ions (fluoride) penetrating the tissue. The fluoride ions form insoluble salts with calcium and magnesium as they penetrate into the tissue. Once the body’s stores of calcium and magnesium have been depleted, systemic toxicity occurs. The majority of deaths resulting from an exposure to HF are often caused by cardiac arrhythmias.
