If you work in an occupation that uses hydrogen fluoride, you may be exposed to this chemical in the workplace. The process of treating HF inhalation injury is highly complex, and more experimental research is still needed to learn proper care techniques. Skin Exposure – Strong HF acid concentrations (over 50%) and anhydrous HF in particular, cause immediate, severe, Exposure usually is unintentional and often is due to inadequate use of protective measures. Progression of skin damage after exposure to hydrofluoric acid (HF) for a duration of 3 or 10 min.

Hydrofluoric acid burns can be fatal, exposure must be addressed immediately. Anthony Stark is a certified EMR (Emergency Medical Responder) in British Columbia, Canada. Exposed people should seek medical treatment as soon as possible. Even small splashes of high-concentration hydrogen fluoride products on the skin can be fatal. People will have a lot of scarring and some loss of function in the affected area. If the hydrogen fluoride release was outside, move away from the area where the chemical was released. The seriousness of poisoning caused by hydrogen fluoride depends on the amount, route, and length of time of exposure, as well as the age and preexisting medical condition of the person exposed.

Hydrofluoric acid (HF) differs from other acids because the fluoride ion readily penetrates the skin, causing destruction of deep tissue layers, including bone. Irritation has been reported with exposure to concentrations as low as 0.24 ppm for 1 hour. Pancreatitis can also be a symptom, which is an inflammation of pancreas that results from internal digestive tract exposure to HF. The fluoride ions in HF bind to calcium and magnesium in the body, which can result in hypocalcemia and hypomagnesmia. If the hydrogen fluoride release occurred indoors, get out of the building. Look for common antacid brands such as Mylanta. Give no more than 4 ounces of either liquid to a child. Don't overdo it with the liquids by trying multiple methods. 2.

Breathing hydrogen fluoride can damage lung tissue and cause swelling and fluid accumulation in the lungs (pulmonary edema). Symptoms of exposure to hydrofluoric acid may not be immediately evident. Showing these signs and symptoms does not necessarily mean that a person has been exposed to hydrogen fluoride. Vomiting can cause the acid to further damage unexposed areas that are undamaged. Hydrofluoric acid (HF) is one of the most dangerous mineral acids because of dissociated fluoride (F −) ions (reviewed in 1).Present in various household products (such as rust removers), a large population of individuals is at risk of HF exposure. A spill of hydrofluoric acid on the skin may be fatal. Anthony Stark is a certified EMR (Emergency Medical Responder) in British Columbia, Canada.
