Seal the bag, and then seal that bag inside another plastic bag. Skin contact with hydrogen fluoride may cause severe burns that develop after several hours and form skin ulcers. 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. The person may need to be admitted to a hospital to continue treatment. Make sure that the clothing comes into contact with as little skin as possible as it is removed. The vapors from anhydrous HF acid or its concentrated solutions can also burn these tissues. Burns. Last Updated: September 6, 2019 People will have a lot of scarring and some loss of function in the affected area. A hydrofluoric acid burn is a chemical burn from hydrofluoric acid. You cannot effectively treat HF exposure on your own. This will help to maximize the efficacy of the gel by increasing absorption. The respiratory effects parallel those of the skin, except effects in the lungs have a rapid onset and patients present with acute respiratory distress. You will be carefully monitored for increased effects of the burn over time, as HF burns can damage your body on a varying time scale depending on the concentration and exposure level. Swallowing hydrogen fluoride can damage the esophagus and stomach. Your doctor may continue with similar tests during follow-up to make sure that long-term symptoms do not develop after you have been discharged. Just as with other HF exposure, your doctor will take a blood test to check your electrolyte balances, look for any arrhythmias or heart palpitations, and will review your Echocardiogram (ECG) to check for any abnormalities. Hydrofluoric acid is also transported for these purposes, so may be present on trucks, trains, ships or in courier vehicles. However, some studies have not found it to be any more effective in reducing electrolyte disturbances than proper rinsing with water. "Calcium gluconate is the preferred treatment of choice for minor HF exposure for the following reasons: The damage may progress for several weeks, resulting in gradual and lingering narrowing of the esophagus. Severe pain can occur even if no burns can be seen. People who survive after being severely injured by breathing in hydrogen fluoride may suffer lingering chronic lung disease. Hydrofluoric (HF) acid, one of the strongest inorganic acids, is used mainly for industrial purposes (eg, glass etching, metal cleaning, electronics manufacturing). Artificial respiration such as CPR is necessary and should be administered by trained professionals if breathing has stopped. If you wear contacts, remove them after washing your hands and put them with the contaminated clothing.

If the person looks as though they are having a hard time breathing, administer oxygen if available. Skin damage caused by concentrated hydrogen fluoride may take a long time to heal and may result in severe scarring. As trifluoroacetic acid contains fluorine, patients with chemical burns caused by trifluoroacetic acid have been given particular attention when treated in the hospital. Learning about hydrofluoric acid burns and how to treat them can decrease the damage and help keep you safe in the future. Elemental fluorine is produced from it. Even small splashes of high-concentration hydrogen fluoride products on the skin can be fatal. Eye exposure to hydrogen fluoride may cause prolonged or permanent visual defects, blindness, or total destruction of the eye. Give no more than 4 ounces of either liquid to a child. Centers for Disease Control and Prevention (CDC), National Institute for Occupational Safety and Health (NIOSH). Exposure to higher concentrations can result in serious damage to the lungs, and fatal pulmonary edema may develop after a delay of several hours. 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. The health department or emergency personnel will arrange for further disposal. If you work in an occupation that uses hydrogen fluoride, you may be exposed to this chemical in the workplace. Inhalation: Coughing, chocking, tightness in the chest, chills, fever, and blue skin can all be a result of inhalation of hydrofluoric acid. Skin Exposure – Strong HF acid concentrations (over 50%) and anhydrous HF in particular, cause immediate, severe, In a natural disaster, you could be exposed to high levels of hydrogen fluoride when storage facilities or containers are damaged and the chemical is released.
