Eye Contact: Rinse immediately with plenty of water for several minutes, remove contact lenses if present, seek medical attention if irritation persists
Skin Contact: Remove contaminated clothing, wash affected area with soap and water, seek medical help for persistent irritation
Inhalation: Move person to fresh air, monitor breathing, administer artificial respiration if needed and qualified, consult a healthcare provider
Ingestion: Rinse mouth thoroughly with water, do not induce vomiting, get medical attention immediately
Symptoms: Redness, dry skin, breathing discomfort, possible nausea if ingested
Suitable Extinguishing Media: Use dry chemical, CO2, foam, or water spray for small fires
Unsuitable Media: Do not use direct water jet on chemical fires involving ionic liquids
Special Hazards: Thermal decomposition products include toxic and corrosive gases; fire can generate hydrogen fluoride and boron trifluoride
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective clothing
Advice: Avoid inhalation of combustion products, cool containers exposed to fire with water spray
Personal Precautions: Ventilate area, use recommended personal protective equipment (gloves, goggles, lab coat), avoid direct contact
Environmental Precautions: Prevent chemical from entering drains, surface water, or soil
Containment Methods: Absorb spill with inert material (sand, diatomaceous earth), place in suitable labeled waste container
Cleanup Methods: Wash area with plenty of water after collection, ventilate area, dispose of waste according to local regulations
Handling Advice: Handle in well-ventilated areas, avoid generating dust or mist, keep container tightly closed
Storage Conditions: Store in a cool, dry, well-ventilated place, away from incompatible substances such as strong acids and bases
Storage Materials: Use corrosion-resistant containers, make sure cap or lid closes tightly
Incompatibilities: Avoid contact with water, strong oxidizers, and alkalis, which can accelerate decomposition
Special Requirements: Inspect containers regularly for damage or leaks
Occupational Exposure Limits: No established limits for this compound; minimize exposure as standard precaution
Engineering Controls: Laboratory-grade chemical fume hood, exhaust venting preferred
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), splash-resistant goggles or safety glasses, lab coat, face shield if splashing possible
Respiratory Protection: Use approved respirator if adequate ventilation cannot be maintained
Hygiene Measures: Wash hands and face after handling, keep work clothing separate from street clothing
Appearance: Colorless to pale yellow liquid
Odor: Mild, ether-like scent
pH: Not applicable (non-aqueous)
Melting Point: -25°C to -20°C (approximate)
Boiling Point: Decomposes before boiling
Flash Point: Estimated above 100°C; use caution due to ionic liquid properties
Solubility: Miscible with water and alcohols
Density: About 1.2 g/cm³ at 25°C
Viscosity: Moderate, flows readily at room temperature
Chemical Stability: Stable at ambient temperature under recommended storage conditions
Incompatible Materials: Avoid strong acids, bases, and oxidizing agents; reacts with water at high temperatures
Hazardous Decomposition: Releases toxic gases including hydrogen fluoride and boron trifluoride at high temperatures or upon strong acid hydrolysis
Polymerization: No known hazardous polymerization
Other Stability Concerns: Prolonged exposure to moisture can cause hydrolysis and reduce shelf life
Acute Toxicity: Not thoroughly tested, low oral and dermal toxicity expected based on similar ionic liquids
Skin Contact: Mild to moderate irritation possible after prolonged or repeated exposure
Eye Contact: May cause mild, temporary irritation
Inhalation: May cause irritation to mucous membranes if inhaled as an aerosol
Chronic Exposure: No data for carcinogenicity, mutagenicity, reproductive toxicity
Other Effects: Excessive exposure can lead to symptoms like skin dryness, rash, respiratory discomfort
Aquatic Toxicity: No specific data for this compound; similar ionic liquids can be moderately toxic to aquatic organisms
Persistence and Degradability: Not readily biodegradable; may persist in the environment
Bioaccumulation: Low potential expected due to solubility and molecular weight
Mobility in Soil: Likely to partition to water rather than soil
Other Environmental Hazards: Breakdown products like hydrogen fluoride pose a risk to water bodies and soil; best practices call for spill containment and avoidance of uncontrolled disposal
Waste Disposal Methods: Treat as hazardous chemical waste, collect in tightly sealed, labeled containers to prevent environmental release
Incineration: Licensed chemical incineration with afterburner and scrubber recommended; do not discharge to sewer or surface water
Empty Containers: Rinse thoroughly, do not reuse for food or beverage, dispose of in accordance with local regulations
Regulatory Compliance: Follow local, regional, and national regulations for ionic liquids and fluorinated compounds
Special Handling: Avoid release to environment, document waste streams for auditor review
