Chemical Name: Lithium Fluoride
Concentration: >99% by weight
CAS Number: 7789-24-4
Impurities: May contain trace amounts of sodium, potassium, magnesium, or calcium fluorides depending on source; individual analysis required for trace contaminant profile
Inhalation: Move person to fresh air; monitor for respiratory distress; seek medical attention if symptoms such as coughing or difficulty breathing develop
Skin Contact: Remove contaminated clothing; rinse skin with copious amounts of water for at least 15 minutes; seek medical attention if irritation or burns occur
Eye Contact: Flush eyes with water gently for at least 15 minutes, lifting upper and lower eyelids; avoid rubbing; contact ophthalmologist as soon as possible
Ingestion: Rinse mouth thoroughly with water; never give anything by mouth to an unconscious person; seek emergency medical attention; do not induce vomiting unless directed by a medical professional
Extinguishing Media: Use dry chemical, sand, or appropriate foam for small fires; lithium fluoride does not support combustion but evolves toxic gases if involved in fire
Hazardous Combustion Products: Hydrogen fluoride, lithium compounds, toxic fluorine compounds
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective suit
Advice for Firefighters: Avoid inhalation of fumes; keep containers cool by spraying with water without spreading the material; move unaffected containers from fire area if safe to do so
Personal Precautions: Keep unnecessary personnel away; use appropriate personal protective equipment including gloves, safety goggles, and dust masks or respirators
Environmental Precautions: Avoid release to the environment; prevent spillage from entering drains, surface water, or soil
Methods for Clean-up: Sweep up using methods that minimize dust generation; place in a suitable, sealed container for disposal; ventilate area after clean-up; wash contaminated surfaces with water and soap
Safe Handling: Minimize airborne dust during transfer, weighing, or disposal; practice good industrial hygiene; avoid contact with skin, eyes, and clothing
Storage Conditions: Store in tightly closed, clearly labeled containers in dry, well-ventilated areas away from acids, moisture, and food materials
Incompatibilities: Avoid storing near strong acids, oxidizers, or sources of moisture as release of hydrogen fluoride gas may occur
Special Requirements: Regularly inspect containers for corrosion and leaks; do not store in glass or ceramic containers due to chemical attack over long-term storage
Exposure Limits: OSHA PEL (soluble fluoride): 2.5 mg/m3 (as fluoride ion); ACGIH TLV: 2.5 mg/m3 (as fluoride)
Engineering Controls: Use local exhaust and general room ventilation to reduce airborne concentrations
Personal Protective Equipment: Safety glasses with side shields or goggles, chemical-resistant gloves (nitrile or rubber), protective clothing, approved respirator under dusty or poorly ventilated conditions
Hygiene Measures: Wash hands thoroughly after handling; remove and wash contaminated clothing before reuse; avoid eating, drinking, or smoking in work areas
Appearance: White, odorless, crystalline solid or powder
Odor: Odorless
pH: Not applicable (weakly basic in water)
Melting Point: Approximately 845°C (1,553°F)
Boiling Point: Approximately 1,676°C (3,049°F)
Density: 2.635 g/cm3
Solubility: Slightly soluble in water (approx. 1.3 g/100 mL at 25°C); insoluble in alcohol
Vapor Pressure: Negligible at ambient temperature
Partition Coefficient (n-octanol/water): Not available
Evaporation Rate: Non-volatile
Decomposition Temperature: Above 1,700°C
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Reactive with strong acids, produces toxic hydrogen fluoride gas upon contact with acids or water in acidic conditions
Hazardous Polymerization: Will not occur
Conditions to Avoid: Humidity, contact with acids, exposure to strong oxidizing agents
Incompatible Materials: Strong acids, strong oxidizers, moisture-sensitive materials
Hazardous Decomposition Products: Hydrogen fluoride, lithium oxides
Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Acute Effects: Toxic if ingested; symptoms can include irritation of the mouth, throat, nausea, vomiting, abdominal pain, diarrhea, and in severe cases, systemic toxicity involving kidney and heart
Chronic Effects: Prolonged exposure may cause fluorosis (damage to bones and teeth), renal and hepatic damage
LD50 (Oral, rat): Around 260 mg/kg
Symptoms of Overexposure: Cough, sore throat, burns to mucous membrane, hypocalcemia, muscle spasms, arrhythmia, kidney failure, bone pain
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, ACGIH, or OSHA
Other Data: Severe poisoning can be fatal if untreated; safety depends strongly on proper handling and rapid first aid
Ecotoxicity: Toxic to aquatic life at relatively low concentrations due to fluoride ion
Persistence and Degradability: Inorganic compound, does not biodegrade
Bioaccumulation Potential: Low for lithium, moderate for fluoride ion, which can accumulate in plants and aquatic organisms
Mobility in Soil: Fluoride ions are mobile and may contaminate groundwater if released
Other Adverse Effects: Overexposure to local aquatic environments may disrupt ecosystem functions and affect sensitive species; necessary to avoid spills and uncontrolled releases into waterways
Waste Treatment Methods: Dispose of in accordance with local, regional, and national laws; do not dispose of via sewage or water systems
Waste Classification: Hazardous waste due to fluoride content; consult local environmental protection authority for approved disposal methods
Packaging: Use sealed, compatible containers; label appropriately for hazardous material
Contaminated Packaging: Rinse containers thoroughly and treat as hazardous waste unless thoroughly decontaminated
