Suitable Extinguishing Media: Water spray, carbon dioxide, foam, or dry chemical
Hazardous Combustion Products: Carbon oxides, nitrogen oxides, hydrogen fluoride, and toxic fluoride gases
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective clothing
Specific Hazards Arising from Chemical: Intense heat may produce toxic gases; avoid inhalation of decomposition products; containers exposed to fire may burst
Advice for Firefighters: Move containers from fire area if safe; keep unaffected containers cool with water spray
Personal Precautions: Evacuate area, ventilate, avoid breathing vapors or mist, wear chemical-resistant gloves and splash-proof goggles
Spill Cleanup: Absorb with inert material like sand or vermiculite, sweep up and place in properly labeled container for disposal
Environmental Precautions: Prevent entry to sewers and public waters; notify authorities if significant spills occur
Decontamination: Wash spillage area with plenty of water after substance removal
Handling: Use in well-ventilated fume hood, avoid inhalation and direct contact, always wear goggles, gloves, and lab coat
Storage: Store in tightly closed original container, in cool, dry place, protected from direct sunlight and sources of ignition
Incompatible Materials: Avoid contact with strong acids, alkalis, and oxidizers
Safe Transfer Practices: Prevent formation of aerosols, use secondary containment for storage of large amounts
Engineering Controls: Employ local exhaust ventilation or chemical fume hood; eye wash stations and safety showers near work area
Personal Protective Equipment: Protective gloves (nitrile recommended), safety goggles, laboratory coat or apron; use flame-resistant materials for large scale work
Occupational Exposure Limits: No established national limits for this ionic liquid; minimize exposure through administrative and engineering controls
Hygiene Measures: Wash hands thoroughly after handling, do not eat/drink/smoke in the laboratory, remove contaminated clothing and wash before reuse
Appearance: Colorless to pale yellow liquid
Odor: Mild, slightly sweet or acetate-like
Boiling Point: Decomposes above 250 °C
Melting Point: Below room temperature (typical for ionic liquids)
Density: Approximately 1.25 g/cm³ at 25 °C
Solubility: Miscible with water and polar organic solvents
Vapor Pressure: Very low at room temperature
pH: Slightly acidic in aqueous solution
Viscosity: High compared to water, varies with temperature
Flash Point: >110 °C (closed cup)
Chemical Stability: Stable under recommended storage conditions
Reactivity: Non-reactive under normal laboratory handling
Hazardous Reactions: Can react with strong acids, alkalis, oxidizers producing toxic fumes
Thermal Decomposition: Produces irritating and toxic fumes of carbon monoxide, carbon dioxide, and hydrogen fluoride at elevated temperatures
Conditions to Avoid: High temperatures, strong oxidizing agents
Polymerization: No dangerous polymerization expected
Routes of Exposure: Inhalation, dermal, ingestion, ocular
Acute Toxicity: Oral and dermal toxicity data limited; extrapolation from imidazolium-based liquids shows moderate risk of severe irritation and toxicity in large amounts
Skin Corrosion/Irritation: Can cause moderate to severe irritation or burns with prolonged contact
Serious Eye Damage/Irritation: Severe eye irritant, risk of permanent injury with direct exposure
Respiratory Sensitization: Vapor/mist may irritate mucous membranes and upper respiratory tract
Chronic Toxicity: Repeated exposure may result in dermatitis, possible liver or kidney impairment (animal data, limited human data)
Carcinogenicity/Mutagenicity: No classification available; inadequate data for this substance
Other Effects: Data gaps exist due to limited widespread use
Toxicity to Aquatic Life: Data for similar ionic liquids suggest moderate-to-high aquatic toxicity, especially to freshwater organisms
Persistence and Degradability: Not readily biodegradable, can persist in aquatic environments
Bioaccumulative Potential: Likelihood of bioaccumulation is low-to-moderate due to high water solubility and chemical structure
Mobility in Soil: High mobility, dissolves into water; can contaminate groundwater
Other Adverse Effects: Possible toxicity to microorganisms in wastewater treatment settings; avoid release into environment
Disposal Methods: Dispose of contents and container in accordance with local, state, and federal environmental regulations; do not discharge to sewers or waterways
Recommended Disposal: Send to licensed chemical incinerator or hazardous waste facility approved for disposal of chemicals with fluorinated organics
Container Disposal: Thoroughly rinse and render container unusable before discarding; follow hazardous waste protocols
Additional Advice: Consult waste disposal contractor; report large releases to environmental authorities
