First Aid MeasuresBack to Contents
【Ingestion】

Administer milk, calcium gluconate, or calcium lactate to bind fluoride ion in the gastrointestinal tract. Antacids (aluminum and/or magnesium based) should be administered. Iv calcium (gluconate or chloride) and magnesium may be necessary to correct serum deficits of these divalent metals in serious overdosage. Monitor ekg and vital signs.
【Inhalation】

Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
【Skin】

Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
【Eyes】

Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
Handling and StorageBack to Contents
【Storage】

Store in tightly closed container in a cool location.
【Handling】

All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Hazards IdentificationBack to Contents
【Ingestion】

Epigastric pain, nausea, dysphagia, salivation, hematemesis, and diarrhea may be noted. These effects may be delayed for several hours following exposure. Gi symptoms are noted when 3 to 5 mg/kg of fluoride are ingested.
【Inhalation】

Respirations are first stimulated then depressed. Death is usually from respiratory paralysis. Following inhalation, coughing and choking may be noted.
【Skin】

Urticaria and pruritus have been reported following exposure to fluoride.
【Eyes】

See Skin.
【Hazards】

Vapors from liquefied gas are initially heavier than air and spread along ground. Some of these materials may react violently with water. Containers may explode when heated. Ruptured cylinders may rocket.

Fire Fighting MeasuresBack to Contents
【Flash Point】

-24
【Fire Fighting】

Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Use alcohol foam, dry chemical or carbon dioxide. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Keep run-off water out of sewers and water sources.
【Fire Potential】

May burn but does not ignite readily.
Accidental Release MeasuresBack to Contents
【Small spills/leaks】

Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.
Stability and ReactivityBack to Contents
【Stability】

No data.
【Incompatibilities】

Reacts with many acids and bases liberating heat and flammable gases (e.g., H2) Reacts with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat Incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides Reacts violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.
【Decomposition】

Toxic fumes are formed when this material is heated. Reacts with water or acids, producing heat and highly toxic fumes.
【Combustion Products】

Emits toxic and/or explosive gases under fire conditions.
