Exposure to hydrogen fluoride can result in severe electrolyte problems. (4) • Anhydrous hydrogen fluoride is one of the strongest acids known. Dial 911 and explain what has happened. • The chemical formula for hydrogen fluoride is HF, and its molecular weight is 20.01 g/mol. You will be subject to the destination website's privacy policy when you follow the link. It is an important feedstock in the preparation of many important compounds including pharmaceuticals and polymers, e.g. Breathing hydrogen fluoride can damage lung tissue and cause swelling and fluid accumulation in the lungs (pulmonary edema). Saving Lives, Protecting People, Chemical Agents: Facts About Personal Cleaning and Disposal of Contaminated Clothing, National Center for Environmental Health (NCEH), Plague Q & A (naturally occurring disease), CDC Plague Home Page (naturally occurring disease), Publications, Education & Training Materials, Viral hemorrhagic fevers (filoviruses [e.g., Ebola, Marburg] and arenaviruses [e.g., Lassa, Machupo]), Case Definition: Caustic or Corrosive Agents, Case Definition: Arsine or Stibine Poisoning, Toxic Syndrome Description: Arsine or Stibine Poisoning, Case Definition: Vesicant (Mustards, Dimethyl Sulfate, and Lewisite), Toxic Syndrome Description: Vesicant/Blister Agent Poisoning, Case Definition: Opioids (Fentanyl, Etorphine, or Others) Poisoning, Potential Health Effects Associated with Hydrazine and Satellite Reentry, Facts about Hydrogen Fluoride (Hydrofluoric Acid), Long-acting anticoagulant (super warfarin), Case Definition: “Super Warfarin” Poisoning, Case Definition: Methyl Bromide Poisoning, Case Definition: Methyl Isocyanate Poisoning, Case Definition: Nerve Agents or Organophosphates, Toxic Syndrome Description: Nerve Agent and Organophosphate Pesticide Poisoning, Case Definition: Riot Control Agent Poisoning, Toxic Syndrome Description: Riot Control Agent Poisoning, Toxic Syndrome Description: Sodium Azide Poisoning, Case Definition: Sodium Monofluoroacetate Poisoning, Case Definition: Sulfuryl Fluoride Poisoning, Super warfarin (long-acting anticoagulant), Case Definition: Trichothecene Mycotoxin Poisoning, U.S. Department of Health & Human Services. If you wear contacts, remove them after washing your hands and put them with the contaminated clothing. (4) • Hydrogen fluoride is a colorless gas that is highly soluble in water. This colorless gas or liquid is the principal industrial source of fluorine, often as an aqueous solution called hydrofluoric acid. (2) Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride is corrosive and can attack the skin. Any clothing that has to be pulled over the head should be cut off the body. %%EOF Severe pain can occur even if no burns can be seen. Do not put the contacts back in your eyes (even if they are not disposable contacts). CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Seek medical attention immediately. Hydrogen contains one electron, and fluorine requires one electron to become stable, so the bond forms readily when the two elements interact. 227 0 obj <> endobj F-.Because the hydroxonium ion is attached to the fluoride ion, it isn't free to function as an acid, thus limiting the strength of HF in water. There it damages the cells and causes them to not work properly. You could be exposed to hydrogen fluoride if it is used as a chemical terrorism agent. Hydrogen fluoride is also used for etching glass and metal. Breathing in hydrogen fluoride at high levels or in combination with skin contact can cause death from an irregular heartbeat or from fluid buildup in the lungs. Eye exposure to hydrogen fluoride may cause prolonged or permanent visual defects, blindness, or total destruction of the eye. Avoid touching contaminated areas of the clothing. M�7�inӫa*4�S7�4�n��������� �`� Hydrogen fluoride is used to make refrigerants, herbicides, pharmaceuticals, high-octane gasoline, aluminum, plastics, electrical components, and fluorescent light bulbs. Its salts and minerals are important chemical reagents and industrial chemicals, mainly used in the production of hydrogen fluoride for fluorocarbons. This gives hydrogen fluoride a simple chemical formula of HF. Calcium gluconate (a calcium sugar) containing gels, solutions, and medications are used to treat hydrogen fluoride poisoning. hydrogen fluoride 100 7664-39-3 Ingredient name % CAS number There are no additional ingredients present which, within the current knowledge of the supplier and in the concentrations applicable, are classified as hazardous to health or the environment and hence require reporting in this section. You may be exposed to hydrogen fluoride as part of a hobby. CDC twenty four seven. ��(cl0 �0 Fluoride salts typically have distinctive bitter tastes, and are odorless. If you think you may have been exposed to hydrogen fluoride, you should remove your clothing, rapidly wash your entire body with water, and get medical care as quickly as possible. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. For more information on evacuation during a chemical emergency, see “. Hydrogen fluoride is available commercially either in an anhydrous (water-free) state or in water solutions of various concentrations. For more information about cleaning your body and disposing of your clothes after a chemical release, see “. The damage may progress for several weeks, resulting in gradual and lingering narrowing of the esophagus. This release could occur at an industrial site or even a retail location. If your eyes are burning or your vision is blurred, rinse your eyes with plain water. If the hydrogen fluoride release was outside, move away from the area where the chemical was released. Hydrogen fluoride is formed through covalent bonding (electron sharing) between a hydrogen atom and a fluorine atom. If you can’t avoid touching contaminated areas, or you aren’t sure which areas are contaminated, put the clothing in the bag using tongs, tool handles, sticks, or similar objects. h�bbd``b`�+��3�`U�J@�A+�c�$u��6�$�$��:�U�@��-�pp\Q@��$#C�"Fr���b_ a�G Fluoride is an inorganic, monatomic anion with the chemical formula F (also written [F] ), whose salts are typically white or colorless. Visible damage may not appear until 12 to 24 hours after the exposure. Anything that touches contaminated clothing should also be placed in the bag. The health department or emergency personnel will arrange for further disposal. Hydrogen fluoride has a molar … As quickly as possible, wash any hydrogen fluoride from your skin with large amounts of water. Hydrogen fluoride goes easily and quickly through the skin and into the tissues in the body. 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. And, severe pain at the exposure site may be the only symptom for several hours. Your doctor may recommend or use products to help neutralize the effects of poisoning. Above room temperature, hydrogen fluoride is a gas, but can be condensed into solid crystals when the temperature is lower than roughly 20 degrees Celsius. HF is widely used in the petrochemical industry as a component of superacids. Hydrogen fluoride can be released when other fluoride-containing compounds such as ammonium fluoride are combined with water. People who survive after being severely injured by breathing in hydrogen fluoride may suffer lingering chronic lung disease.
