Protective Equipment for Firefighters: Wear full protective clothing with self-contained breathing apparatus, chemical-resistant gloves, and eye protection
Firefighting Instructions: Remove containers from fire area if safe, use water spray to cool surfaces, avoid inhaling dangerous vapors, stay upwind
Personal Precautions: Evacuate area, use personal protective equipment such as gloves, goggles, and splash-proof clothing, avoid breathing vapors
Environmental Precautions: Prevent spillage from entering drains, soil, or watercourses, inform authorities if environmental contamination occurs
Methods for Clean Up: Absorb with inert dry material such as sand or vermiculite, collect in a chemical waste container, ventilate the area thoroughly, dispose of according to local regulations
Safe Handling: Use only in well-ventilated areas, avoid formation of aerosols, avoid contact with skin, eyes, and clothing, wash hands and exposed skin after use, do not eat, drink, or smoke near the material
Storage Conditions: Store in a tightly closed original container, in a cool, dry, and well-ventilated space, protect from strong oxidizers, acids, and direct sunlight, keep away from heat sources
Incompatible Materials: Strong oxidizing agents, acids, bases, moisture-sensitive chemicals
Occupational Exposure Limits: No established regulatory standards for this compound
Engineering Controls: Use chemical fume hood or equivalent local exhaust ventilation to minimize exposure
Personal Protective Equipment: Chemical-resistant gloves (nitrile or PVC), safety goggles with side shields, lab coat, suitable face shield, chemical apron for large quantities
Hygiene Measures: Wash hands after handling, do not allow product to contact skin, remove contaminated clothing immediately, ensure eyewash stations and safety showers are accessible
Appearance: Colorless to pale yellow liquid or viscous oil
Odor: Mild, slightly sweet or amine-like
Melting Point: approximately -25°C
Boiling Point: >300°C (decomposes)
Density: 1.37–1.39 g/cm³ at 25°C
Solubility: Low in water, high in organic solvents (e.g., dichloromethane, acetonitrile)
Vapor Pressure: Very low
Viscosity: 35–75 mPa·s at 25°C
pH: Not applicable (neat liquid)
Chemical Stability: Stable under standard conditions, decomposes upon strong heating or exposure to acids/bases
Conditions to Avoid: Heating above 200°C, strong mechanical shock, exposure to moisture or high humidity
Incompatible Materials: Strong oxidizers, mineral acids, reactive metals, strong bases
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, hydrogen fluoride, nitrogen oxides, sulfur oxides, toxic fluorinated gases
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Oral LD50 (rat) >2000 mg/kg (estimated), moderate skin/eye irritant
Symptoms: Irritation of eyes and skin, gastrointestinal discomfort, nausea, coughing, difficulty breathing
Chronic Effects: Repeated exposure may affect liver and kidneys, sensitization unlikely but not ruled out
Carcinogenicity: No data indicating carcinogenic potential according to available sources
Mutagenicity/Reproductive Toxicity: Inconclusive or insufficient data available
Aquatic Toxicity: May cause long-term adverse effects in aquatic systems, aquatic invertebrates EC50 (daphnia) >100 mg/L (estimated)
Persistence and Degradability: Persistent due to ionic liquid nature, slow biodegradation in soil/water
Bioaccumulation: Potential for accumulation in aquatic organisms, due to high partitioning coefficient
Mobility in Soil: Low volatility, slight mobility if spilled
Other Adverse Effects: Chronic exposure can impact algae and micro-organisms in water systems
Disposal Methods: Dispose of as hazardous chemical waste in accordance with local, regional, or national regulations, do not dispose of in domestic sewage or regular waste streams
