Emergency Overview: White crystalline powder, odorless, highly toxic by ingestion and inhalation, causes serious health risks with acute and prolonged exposure
Chemical Name: Sodium Fluoride
Common Name: Sodium Fluoride
Concentration: 99% or higher (analytical grade)
Impurities: None expected with proper manufacturing practices
Other Ingredients: None listed
Hazardous Components: Sodium Fluoride is classified as hazardous under OSHA and GHS systems
Inhalation: Move person to fresh air immediately; keep at rest; seek medical attention even if symptoms improve, as fluoride toxicity can worsen
Skin Contact: Remove contaminated clothing, rinse skin thoroughly with water for at least 15 minutes; do not use abrasive soaps
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing and seek medical guidance
Ingestion: Do not induce vomiting; rinse mouth thoroughly with water; get medical help right away - risk of systemic toxicity and cardiac arrest
Symptoms of Exposure: Burning, irritation, pain, nausea, vomiting, abdominal pain, convulsions, hypocalcemia, respiratory distress
Note to Physicians: Treat with calcium gluconate for fluoride toxicity; monitor cardiac function closely
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, alcohol-resistant foam
Unsuitable Extinguishing Media: No known incompatible media for sodium fluoride
Fire Hazards: Material does not burn easily; toxic fumes may form at high temperatures including hydrogen fluoride or sodium oxides
Special Protective Equipment for Firefighters: Wear full protective gear with self-contained breathing apparatus
Firefighting Advice: Stay upwind of fire, avoid inhaling dust or gases, keep containers cool using water spray to prevent rupture
Explosion Hazard: Dust-air mixtures may present explosion risk with strong ignition source
Personal Precautions: Evacuate unprotected personnel from area, use dust mask, gloves, goggles, respirator when necessary
Environmental Precautions: Do not allow material to enter sewers, soil, surface waters; sodium fluoride is hazardous to aquatic life
Cleanup Methods: Sweep up carefully to avoid dust, use HEPA vacuum or wet sweeping, place in properly labelled container; dispose of according to local regulations
Spill Response: Isolate area, ventilate, notify authorities if large quantities are spilled or waterways threatened
Decontamination Advice: Flush surface thoroughly with water after clean-up
Safe Handling: Minimize contact with dust, use closed systems and local extraction when possible, avoid eating, drinking or smoking where product handled
Advice on Storage: Store in cool, dry, well-ventilated area, away from acids and organic materials
Packaging Materials: Use containers resistant to corrosion, clearly labelled; avoid using glass if contacting hydrofluoric acid
Specific Use Restrictions: Only trained professionals should handle large quantities or use in industrial processes; access limited to authorized personnel
Incompatibilities: Strong acids (especially sulfuric or hydrofluoric acid), aluminum, magnesium, strong oxidizers
Occupational Limits: OSHA PEL: 2.5 mg/m3 (as fluoride), ACGIH TLV: 2.5 mg/m3 (as fluoride)
Engineering Controls: Use process enclosures, local exhaust ventilation, general room ventilation
Personal Protective Equipment: Chemical goggles or face shield, suitable gloves (neoprene, nitrile), protective clothing, change out of contaminated clothes
Respiratory Protection: Use NIOSH-approved respirators in situations of high dust or inadequate ventilation
