Inhalation: Move to fresh air, keep comfortable, seek medical advice for coughing, sore throat, or shortness of breath
Skin Contact: Remove contaminated clothing, rinse affected skin with water for at least 15 minutes, seek medical attention for irritation or burns
Eye Contact: Rinse eyes with water for at least 20 minutes, lift eyelids, remove contact lenses if present, seek immediate medical advice
Ingestion: Do not induce vomiting, rinse mouth, seek medical advice or call poison control immediately
Important Symptoms and Effects: Severe irritation or burns to mucous membranes, skin, eyes; possible systemic toxicity and hypocalcemia due to fluoride ions
Medical Note for Physicians: Treat with symptomatic and supportive measures, monitor blood calcium and potassium, consider calcium gluconate for fluoride exposure
Suitable Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or alcohol-resistant foam
Special Hazards: Releases toxic hydrogen fluoride and nitrogen oxides on decomposition, avoid inhalation of fumes
Protection for Firefighters: Wear self-contained breathing apparatus and full protective gear
Firefighting Instructions: Move containers away from fire area if safe, prevent runoff into water sources, use non-sparking tools
Personal Precautions: Evacuate unprotected personnel, ventilate area, wear chemical-resistant gloves, goggles, and protective clothing
Environmental Precautions: Avoid discharge into drains, soil, or surface waters, contain spill with inert material
Cleaning Methods: Absorb spill with sand or vermiculite, scoop up and dispose of in accordance with local, state, and federal regulations, wash area with dilute calcium gluconate solution to neutralize fluoride
Safe Handling: Use only in ventilated areas or fume hood, avoid contact with skin, eyes, and clothing, prevent inhalation of dust or vapors
Storage Conditions: Store in tightly closed containers, keep in cool, dry, and well-ventilated area, segregate from acids, oxidizers, and incompatible materials, label clearly and store away from foodstuffs
Incompatible Materials: Avoid strong acids, oxidizers, glass, silica, and water-reactive substances
Exposure Limits: No established OSHA or ACGIH limits for this compound, minimize exposure as for all fluoride compounds
Engineering Controls: Chemical fume hood, exhaust ventilation, closed systems for handling
Respiratory Protection: NIOSH-approved respirator with acid gas cartridge or self-contained breathing apparatus under emergency or high-exposure conditions
Skin Protection: Chemical-resistant gloves (nitrile, PVC), laboratory coat, chemical apron
Eye Protection: Safety goggles with side shields, face shield for handling bulk quantities
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing, avoid bringing food and beverages into work area
Appearance: White crystalline powder, may appear as wet or sticky due to hydration
Melting Point: Range between 35-45°C (decomposes)
Boiling Point: Decomposes before boiling
Odor: Odorless
pH (1% solution): Strongly basic, pH typically above 10
Water Solubility: Highly soluble in water and polar solvents
Vapor Pressure: Negligible at room temperature
Density: About 1.3 g/cm³ (variable due to hydration)
Partition Coefficient: Not available
Chemical Stability: Stable under recommended storage conditions, hygroscopic and absorbs moisture rapidly
Reactivity: Reacts with acids and silica-containing materials, attacks glassware
Hazardous Decomposition Products: Produces hydrogen fluoride, ethylamines, nitrogen oxides when heated or in contact with acids
Conditions to Avoid: Moisture, elevated temperatures, contact with acids and oxidizers
Incompatible Materials: Acids, oxidizing agents, glass, ceramics, and silica-containing material
Acute Toxicity: Oral LD50 in rats 56 mg/kg (as fluoride), marked toxicity through ingestion and skin contact
Skin Corrosion/Irritation: Causes severe burns, may penetrate skin leading to systemic toxicity
Eye Damage/Irritation: Causes irreversible eye damage, severe burning, blurred vision
Respiratory Sensitization: Inhalation of dust or fumes leads to irritation, chest pain, or pulmonary edema
Chronic Toxicity: Fluoride build-up causes bone and dental fluorosis, possible kidney damage with repeated or prolonged exposure
Relevant Symptoms: Burning pain, redness, blurred vision, tingling, numbness due to nerve toxicity, convulsions in severe cases
Ecotoxicity: Highly toxic to aquatic life, fluoride ions lead to fish kills, disrupts aquatic ecosystems
Persistence and Degradability: Inorganic compound, does not degrade readily, remains in environment as ionic fluoride
Bioaccumulation Potential: Low potential in higher organisms; accumulation possible in lower trophic levels
Mobility in Soil: High mobility; leaches quickly into groundwater due to water solubility
Other Adverse Effects: Can alter water chemistry, hazardous to plants and animals, do not allow product to reach waterways
Waste Treatment Methods: Collect all waste in sealed containers, label as hazardous chemical waste, consult local regulations for acceptable disposal, avoid pouring down the drain
Disposal of Contaminated Packaging: Rinse empty containers thoroughly, dispose of rinsate as chemical waste, destroy containers if possible, do not reuse for other purposes
Special Precautions: Neutralize residue with calcium compounds to form insoluble salts, refer to local environmental authority for safe management of fluoride-containing waste
