Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam, water spray
Unsuitable Extinguishing Media: Direct water jet may spread the liquid
Special Hazards: Vapors can form hazardous decomposition byproducts like toxic nitrogen oxides, cyanic species
Protective Equipment: Firefighters should wear self-contained breathing apparatus, full protective gear
Advice for Firefighters: Cool containers with water, prevent run-off from entering drains or water bodies, evacuate area if large fire develops
Personal Precautions: Avoid breathing vapors or direct contact with liquid, use chemical-resistant gloves, goggles, protective clothing
Environmental Precautions: Avoid release into environment, contain spill to prevent entry into sewers or waterways
Cleanup Methods: Absorb spill with inert material such as sand, collect in containers for disposal, ventilate area well
Decontamination: Wash affected area with water and mild neutral detergent, dispose of contaminated materials as hazardous waste
Safe Handling: Use only in well-ventilated locations, avoid splashes and spills, keep containers tightly closed when not in use, avoid direct skin and eye exposure
Hygiene Measures: Wash hands thoroughly after handling, avoid eating or drinking near product
Storage Conditions: Store in original container, tightly sealed, in cool, dry, ventilated place away from heat and sunlight, keep away from incompatible materials such as strong acids and oxidizers
Incompatible Materials: Strong acids, strong bases, oxidizing agents, water-reactive chemicals
Shelf Life: Stable under recommended storage; inspect regularly for leaks or damage
Engineering Controls: Use fume hoods, local exhaust ventilation, facilities for washing eyes and skin nearby
Personal Protective Equipment (PPE): Chemical-resistant gloves (e.g., nitrile), laboratory coat or apron, safety goggles or face shield, use respiratory protection if ventilation is inadequate
Environmental Exposure Control: Prevent further leakage or spillage if safe, avoid uncontrolled release into environment, use bunds for storage areas
Occupational Exposure Limits: No specific national exposure limits for ionic liquids; practice general chemical safety guidelines
Appearance: Clear or pale yellow liquid
Odor: Very mild, faint sweet note
Melting Point: -19°C
Boiling Point: Not established (often decomposes before boiling)
Flash Point: >110°C
Auto-Ignition Temperature: Not specified by manufacturer

Viscosity: Moderate at room temperature
Chemical Stability: Stable under normal conditions, avoid heat, moisture, and sources of ignition
Reactivity: Does not react violently with air or water under standard laboratory situations
Hazardous Reactions: Contact with strong acids, bases, or oxidizers can lead to dangerous decomposition
Decomposition Products: Can produce toxic gases such as nitrogen oxides, cyanide-containing vapors on thermal breakdown
Conditions to Avoid: Elevated temperature, flame, high humidity, direct sunlight, sources of static discharge
Acute Toxicity: Ingestion or inhalation can cause moderate toxicity; animal testing indicates low LD50 but avoid deliberate exposure
Skin Corrosion/Irritation: Prolonged contact causes irritation, redness
Eye Damage/Irritation: Causes irritation, watering, and discomfort
Respiratory Sensitization: Vapors can cause cough, sore throat, nasal irritation
Chronic Effects: No extensive chronic studies reported; long-term or repeated exposure should be minimized
Carcinogenicity: No evidence shows carcinogenic properties according to current research
Mutagenicity: Not classified as mutagenic but data remains limited
Additional Toxicological Data: Handle with caution; potential effects from long-term exposure are under study in green chemistry and toxicology fields
Toxicity to Aquatic Life: Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment
Persistence and Degradability: Not readily biodegradable, stays persistent in soil and water environments
Bioaccumulation Potential: Low to moderate, depends on local environmental conditions
Mobility in Soil: High water solubility leads to mobility in moist soils
Other Hazards: Ionic liquids represent emerging contaminants; environmental exposure poses risks for water organisms
Waste Treatment Methods: Dispose through licensed chemical waste contractors, always follow local and national hazardous waste regulations
Product Disposal: Do not pour into drains, sewers, or natural watercourses
Contaminated Packaging: Incinerate or handle as hazardous industrial waste according to local laws
