General Advice: Take person to fresh air and consult medical professional if symptoms develop
Inhalation: Move exposed individual to fresh air; offer oxygen if breathing feels labored
Skin Contact: Wash with water and mild soap for several minutes after removing any contaminated clothing
Eye Contact: Rinse eyes carefully under running water for at least 15 minutes; remove contact lenses if easily possible
Ingestion: Do not induce vomiting; rinse mouth with water if individual is conscious and seek prompt medical advice
Most Important Symptoms: Temporary discomfort in eyes, possible mild irritation of skin and respiratory tracts; no unusual delayed effects noted in the available literature
Indication of Immediate Medical Attention Needed: See physician for persistent discomfort or unusual symptoms
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical powder, carbon dioxide
Unsuitable Extinguishing Media: Do not use strong water jet, as product may spread
Special Hazards: Product decomposes at high temperature to release toxic gases including hydrogen fluoride, boron trifluoride, or related materials
Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective clothing
Specific Methods: Move containers from fire area if possible without risk; cool with water mist to avoid vessel rupture
Combustion Products: Carbon oxides, nitrogen oxides, boron compounds, hydrogen fluoride
Advice for Firefighters: Avoid direct contact with product runoff; control fire-fighting water for potential hazard to drains and sewers
Personal Precautions: Use gloves, goggles, and lab coat; avoid inhaling dust or vapor
Environmental Precautions: Prevent significant release to drains, soil, or waterways; product can be harmful to aquatic life if released in quantity
Cleanup Methods: Absorb with inert material like sand or vermiculite; place in labeled container for disposal
Surface Decontamination: Wash contaminated surfaces with soap and water, followed by thorough rinse
Spill Reporting: Notify responsible authorities if spill is large or enters environment; follow protocol for hazardous materials
Handling: Work in well-ventilated area; use fume hood if possible when heating or stirring
Technical Measures: Avoid handling near open flames or sources of heat; transfer and use tools should be clean and dry
Hygienic Practices: Wash hands after use; remove contaminated clothing and equipment before leaving area
Storage Conditions: Store at room temperature, shielded from direct sunlight and sources of moisture
Container Requirements: Use air-tight, chemical-resistant containers; check compatibility with tetrafluoroborate salts
Incompatible Materials: Avoid contact with strong bases, acids, or oxidizers, and sources of water to prevent hydrolysis
Occupational Exposure Limits: No specific limits issued; keep exposure as low as possible
Engineering Controls: Work in chemical fume hood or in well-ventilated conditions
Respiratory Protection: Required for dust or vapor generation; use approved respirator in poorly ventilated spaces
Skin Protection: Wear suitable chemical-resistant gloves (nitrile or neoprene recommended), laboratory coat or apron
Eye Protection: Chemical splash goggles and, where needed, face shield
General Safety Measures: Avoid eating, drinking, or smoking in the processing area; follow strict laboratory hygiene
Appearance: Colorless to pale yellow liquid or low-melting solid
Odor: Faint; not easily detected
pH: Not applicable as pure substance; hydrolysis by water produces acidic solutions
Melting Point: Typically in the range of 10–20°C, varies by purity
Boiling Point: Decomposes before boiling
Flash Point: >110°C (closed cup, typical for ionic liquids)
Flammability: Low, but combustible; avoid open flames
Solubility: Miscible with water and polar organic solvents
Vapor Pressure: Negligible at room temperature
Density: Approximately 1.2–1.3 g/cm³ at 20°C
Partition Coefficient (n-octanol/water): No value available; ionic liquids are not very lipophilic

Chemical Stability: Stable under normal laboratory conditions
Conditions to Avoid: Prolonged exposure to air and moisture; elevated temperatures
Incompatible Materials: Strong oxidizers, acids, bases, and materials that react with fluoro compounds
Hazardous Decomposition Products: Hydrogen fluoride, boron trifluoride, organic decomposition products
Polymerization: Not known to occur
Reactivity: Tetrafluoroborate can hydrolyze slowly in moist conditions; care with water contamination advised
Acute Toxicity: No data for oral, dermal, or inhalation LD50 in humans; limited data suggest low acute toxicity
Skin Corrosion/Irritation: May cause mild irritation after prolonged contact
Serious Eye Damage/Irritation: May cause discomfort or redness with direct contact

Potential Routes of Exposure: Skin, eye, inhalation of dust or mist, ingestion
Ecotoxicity: Product may cause adverse effects to aquatic organisms if spilled in significant quantity
Persistence and Degradability: Not readily biodegradable in standard tests
Bioaccumulative Potential: Not expected to bioaccumulate due to ionic character
Mobility in Soil: Product expected to have some mobility because of water solubility, but strong adsorption to soil cannot be ruled out
