Inhalation: Move to fresh air. Seek medical attention for persistent irritation, cough, or breathing difficulty.
Skin Contact: Remove contaminated clothing. Wash area thoroughly with soap and water. Get medical advice if irritation appears.
Eye Contact: Rinse eyes cautiously with water for several minutes. Remove contact lenses if present and easy. Continue rinsing. Seek medical attention if discomfort continues.
Ingestion: Rinse mouth thoroughly. Do not induce vomiting. Get medical aid if symptoms develop.

Special Hazards: Combustion produces toxic fumes such as carbon oxides, fluorine-containing compounds, nitrogen oxides, and sulfur dioxide.
Protective Equipment: Firefighters use self-contained breathing apparatus and full protective gear.
Special Procedures: Cool containers exposed to fire with water spray. Use water to keep fire-exposed containers cool.
Personal Protection: Wear gloves, goggles, and appropriate protective clothing. Ensure adequate ventilation.
Environmental Precautions: Prevent spillage from entering drains, soil, or waterways. Alert authorities if significant spillage occurs.
Spill Response: Contain spillage. Absorb with inert material (sand, vermiculite). Clean up with non-sparking equipment. Store collected material in proper chemical waste container.
Decontamination: Wash affected area with water and detergent.
Precautions for Safe Handling: Prevent contact with skin, eyes, and clothing. Work in a chemical fume hood or with good general ventilation. Wash hands after use.
Storage Conditions: Keep container tightly closed in a dry, cool, and well-ventilated place. Protect from moisture and incompatible substances. Keep away from direct sunlight.
Incompatibles: Strong oxidizing agents, strong acids, strong bases, moisture.
Special Handling Advice: Use appropriate containment to avoid environmental contamination.
Occupational Exposure Limits: No established OSHA, ACGIH, or NIOSH limits.
Engineering Controls: Use chemical fume hood or ensure adequate ventilation.
Personal Protective Equipment: Safety goggles, butyl or nitrile gloves, laboratory coat.
Respiratory Protection: Use NIOSH-approved respirator if exposure likely.
Hygiene Measures: Wash hands and face after handling. Do not eat, drink, or smoke where the product is handled or stored.

Reactivity: No significant reactivity under normal conditions. Reacts with strong oxidizers.
Decomposition Products: Carbon oxides, hydrogen fluoride, nitrogen oxides, sulfur oxides. Releases toxic and corrosive gases.
Polymerization: Will not occur.
Incompatible Materials: Strong acids, bases, oxidizers, moisture.
Other Hazards: Can decompose slowly if exposed to light or heat.
Acute Toxicity: Low oral and dermal toxicity based on available data. A detailed LD50 value not established.
Irritation: Causes skin and eye irritation; may cause respiratory discomfort if inhaled.
Corrosivity: Not corrosive to metals or tissue.
Carcinogenicity: No data indicating carcinogenic potential.
Mutagenicity: Not expected to be mutagenic based on structure-activity relationships.
Sensitization: Not classified as a sensitizer.
Chronic Toxicity: Long-term exposure data lacking; effects not anticipated under proper handling.
Other Information: Some ionic liquids can be absorbed via the skin, so care makes sense for large exposures.
Toxicity to Aquatic Life: May be toxic to aquatic organisms depending on concentration and exposure time.
Persistence and Degradability: Biodegradability is low. Tends to persist in the environment.
Bioaccumulation Potential: Low, but may accumulate in sediment or soil over time.
Mobility in Soil: Limited water solubility reduces leaching, but persistence raises risk in aquatic environments.
Other Adverse Effects: No known significant effects besides aquatic toxicity. Proper disposal and containment help reduce risk.
Waste Disposal: Collect and dispose of material in accordance with federal, state, and local environmental regulations.
Methods of Disposal: Incineration recommended for large quantities; small amounts can be absorbed in inert material and sent to approved waste disposal facility.
Contaminated Packaging: Rinse thoroughly before disposal. Follow hazardous waste protocols.
Considerations: Do not release into natural waters or household drains.
