Eye contact: Flush eyes gently but thoroughly with water for at least 15 minutes, remove contacts if present and easy to take out, call for immediate medical attention if irritation or vision changes persist
Ingestion: Rinse mouth, do not induce vomiting unless directed by medical personnel, provide medical attention urgently, especially for any signs of discomfort or gastrointestinal distress
Notes to Physician: Treat as fluoride exposure, monitor for systemic toxicity or delayed symptoms after substantial exposure
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, avoid direct water stream on product in powder or molten state
Unsuitable Extinguishing Media: Do not use standard water jets
Hazardous Combustion Products: Toxic and irritating gases including hydrogen fluoride, lithium oxides, boron oxides
Specific Hazards: Emits hazardous vapors and corrosive mist on fire, reacts vigorously with water to produce HF
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and chemical protective clothing
Firefighting Procedures: Approach upwind, avoid inhalation, prevent firewater from entering drains
Personal Precautions: Wear approved respirator and chemical protective gloves, make sure eye protection fits securely, remove unnecessary personnel from area
Environmental Precautions: Prevent product from entering water courses or drains, contain spill using dry earth or sand
Spill Cleanup: Use inert, non-combustible absorbent for collection, sweep carefully to eliminate dust and static, place in sealed, labelled containers for disposal
Decontamination: Wash affected spill areas with large volumes of water after collection; neutralize with alkaline materials like calcium carbonate if permitted
Safe Handling: Avoid inhaling dust, keep away from open flames, sources of static, and high humidity; do not get in eyes or skin
Handling Procedures: Use spark-proof tools, work in well-ventilated fume hood or dedicated enclosure, transfer powders with minimum agitation to prevent airborne particles
Storage Requirements: Store locked up in tightly sealed, corrosion-resistant containers in a cool, dry area, segregate from acids, water, and incompatible materials
Storage Temperature: Controlled room temperature, away from moisture and oxidizers
Shelf Life: Confirm shelf life by manufacturer’s lot details, generally stable in original packaging
Engineering Controls: Local exhaust ventilation, chemical fume hood, explosion-proof equipment for powder transfer
Exposure Limits: No specific occupational exposure limit for LiBF4, for fluoride anion follow ACGIH TLV for inorganic fluorides (2.5 mg/m3 as F)
Personal Protection: Chemical-resistant gloves (nitrile or neoprene), protective lab coat, safety goggles with side protection, respiratory protection (half-mask with P2 filter or better) during dust generation
Hygiene Practices: Wash hands and face thoroughly after handling and before breaks or meals, do not eat or smoke in work area
Appearance: White to off-white crystalline powder
Odor: Odorless
Molecular Weight: 93.75 g/mol
Melting Point: Between 293°C and 298°C
Boiling Point: Not applicable (sublimes or decomposes on strong heating)
Solubility: Soluble in water, acetonitrile, carbonate solvents
Density: About 0.85 g/cm3 at 25°C
pH (aqueous): Typically slightly acidic
Vapor Pressure: Negligible at room temperature
Partition Coefficient: Data not available
Other Properties: Hydrolyzes in moisture to release HF gas
Reactivity: Reacts spontaneously with acids, strong bases, and humid air
Chemical Stability: Stable in dry, sealed containers under recommended storage conditions, decomposes on prolonged exposure to moisture, acids, or above 300°C
Hazardous Reactions: Exothermic reaction with water yields HF, formation of toxic gases when heated or contacted with acids
Incompatible Materials: Water, acids, alcohols, strong oxidants
Decomposition Products: Hydrogen fluoride, boron oxides, lithium oxides, fluorinated compounds
Acute Toxicity: LD50 (oral, rat): Estimated 200-300 mg/kg; harmful at low doses
Inhalation: Dust inhalation irritates respiratory system, can lead to coughing, shortness of breath, and in severe cases pulmonary edema
Skin Contact: Causes redness, pain, and possible chemical burns with prolonged exposure
Eye Contact: Rapid, severe irritation, possible corneal damage
Chronic Effects: Prolonged exposure to fluorides leads to skeletal fluorosis, systemic toxicity, dental changes
Sensitization: No documented effects, use caution due to irritant properties
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, or OSHA
Reproductive Toxicity: No data available for lithium tetrafluoroborate, fluoride toxicity may affect developing fetal skeleton in high exposures
Ecotoxicity: Highly toxic to aquatic organisms due to fluoride release, disrupts aquatic enzyme pathways, no safe threshold for aquatic invertebrates
Persistence and Degradability: Inorganic salt, does not degrade in environment, fluoride ions persist in soil and water
Bioaccumulation: Fluoride ions bioaccumulate in bones and teeth of animals, potential for long-term effects on aquatic and terrestrial food chains
Mobility in Soil: Highly mobile as ionic fluoride, migrates easily through soil and groundwater
Other Adverse Effects: Contributes to water fluoridation and may harm sensitive plant species if spillage occurs near growing areas
Waste Disposal: Treat as hazardous chemical waste, dispose of through licensed hazardous waste contractor
Incineration: Not recommended, as combustion releases HF and toxic gases
Rinsate: Collect and treat any contaminated water as hazardous; do not release untreated liquid to drains
Packaging: Triple rinse empty containers, crush or puncture before landfilling or recycling according to local regulations
Regulatory Requirements: Follow national and local hazardous waste management laws—ensure liability documentation for cradle-to-grave chain of custody
