Inhalation: Move person to fresh air, monitor breathing, seek medical attention if symptoms persist or worsen
Skin Contact: Remove contaminated clothing, flush skin with plenty of water and mild soap, seek medical attention if irritation occurs or signs of chemical burns appear
Eye Contact: Immediately flush eyes with plenty of lukewarm water for at least 15 minutes, remove contact lenses if present, continue rinsing, seek prompt ophthalmologic assessment
Ingestion: Do not induce vomiting, rinse mouth thoroughly with water, give water if conscious, swift medical evaluation recommended
Advice for Physician: Treat symptomatically, monitor vital signs, manage airway and breathing as needed, no specific antidote available for ingestion or skin exposure
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, foam, do not use direct water jet on burning substance due to risk of chemical splatter
Unsuitable Media: Water in large quantities can spread fire or chemical contamination
Hazards from Combustion Products: May evolve toxic fumes of fluorine, sulfur oxides, nitrogen oxides, hydrogen fluoride, and carbon dioxide
Protective Equipment: Full turn-out gear, positive pressure self-contained breathing apparatus
Fire Fighting Instructions: Cool exposed containers with water spray, avoid breathing vapors or dust from decomposition products, evacuate upwind if possible
Personal Precautions: Evacuate unnecessary personnel, ventilate closed spaces, wear appropriate chemical-resistant gloves, safety goggles, and protective clothing
Environmental Precautions: Prevent further leakage or spillage from entering drains, sewers, or waterways; avoid contamination of soil
Containment and Cleaning: Absorb with earth, sand, or inert material; collect spills into suitable waste containers equipped with a sealing lid; decontaminate area with soap and water; dispose using licensed waste contractor
Special Measures: Avoid generating dust or aerosols, and ensure proper waste labeling
Handling: Use in a laboratory fume hood, minimize exposure to vapor and dust, ensure containers are tightly capped, avoid ingestion and inhalation, do not eat, drink, or smoke in work area
Storage: Store in tightly closed containers, away from incompatible chemicals like strong oxidizers or acids; maintain storage in cool, dry, and well-ventilated environment; label containers with date and content, avoid prolonged exposure to light and heat sources
Special Considerations: Regularly check containers for leaks or degradation, restrict access to authorized trained individuals only
Exposure Limits: No established regulatory exposure limits, but use best industry hygiene practices
Engineering Controls: Mechanical ventilation, fume hoods, and proper area exhaust
Personal Protective Equipment: Chemical-resistant gloves (nitrile or similar), goggles or face shield, lab coat, closed footwear, respiratory protection (half-mask or better if dust or vapor is present)
Hygiene Measures: Wash hands before breaks and after finishing work, remove contaminated clothing before leaving area
Environmental Control: Prevent release into local drains, provide spill kits and eye-wash stations
Physical State: Liquid at room temperature
Color: Colorless to pale yellow
Odor: Slight, characteristic
pH: Not applicable (ionic liquid)
Melting Point: 25 – 35°C
Boiling Point: Decomposes before boiling

Viscosity: High, typical for ionic liquids
Other Properties: Non-volatile, stable to moderate heating in inert atmosphere
Chemical Stability: Stable at room temperature under recommended storage; sensitive to strong acids and oxidizing agents
Reactivity: Can react exothermically with strong oxidants or mineral acids; avoid mixing with incompatible substances
Conditions to Avoid: Overheating, moisture ingress, exposure to strong light, open flames
Incompatible Materials: Strong oxidizers, mineral acids, metals that may react with ionic liquids

Chronic Effects: Repeated or prolonged exposure can aggravate current skin or respiratory conditions
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No known long-term studies, best to use precaution and avoid repeated exposure
Medical Conditions Aggravated by Exposure: Pre-existing eye, skin, or lung conditions
Ecotoxicity: Predicted hazardous to aquatic organisms; possible bioaccumulation in water systems
Persistence/Degradability: Stable under most biological conditions, slow degradation expected
Mobility: Can move with ground or surface water if spilled
Bioaccumulation: Potential exists due to chemical stability and lipophilicity
