Inhalation: Remove person to fresh air, seek medical advice if symptoms persist or respiratory problems develop
Skin Contact: Remove contaminated clothing, immediately wash with soap and flowing water for at least 15 minutes, obtain medical attention for irritation or visible skin injury
Eye Contact: Rinse eyes carefully with water for several minutes, removing contact lenses if possible, continue rinsing, seek medical attention if pain, redness, or vision problems occur
Ingestion: Rinse mouth with water, seek medical advice, do not induce vomiting unless directed by medical personnel
Most Important Symptoms: Irritation, redness, cough, headache
Notes for Physician: Symptomatic treatment, monitor for delayed respiratory complications
Suitable Extinguishing Media: Dry chemical, CO2, alcohol-resistant foam, water spray
Unsuitable Media: Avoid full water jet, which may spread material
Special Hazards: Produces toxic fumes of carbon oxides, nitrogen oxides, sulfur oxides, hydrogen fluoride in fire conditions
Protective Equipment: Firefighters must wear self-contained breathing apparatus and protective suit
Additional Instructions: Cool fire-exposed containers with water, prevent contaminated water run-off from entering drains
Personal Precautions: Wear chemical-resistant gloves, goggles, lab coat, and, if dusting, respiratory protection
Environmental Precautions: Prevent entry to sewers, drains, and water bodies, avoid soil contamination
Methods for Clean-Up: Contain spill, collect absorbed material with inert absorbent (sand, vermiculite), place in a container for disposal, ventilate area, wash site of release after material cleanup
Decontamination: Use water and mild detergent to remove residues, avoid use of solvents
Safe Handling: Work in well-ventilated areas, handle only in areas with local exhaust ventilation or fume hood, avoid direct contact with skin or eyes, keep away from incompatible materials
Avoid: Prolonged or repeated exposure, eating, drinking, or smoking while handling, inhalation of vapor or dust
Storage: Store tightly closed in original container, in a cool, dry place, away from heat sources, direct sunlight, and moisture, segregate from strong oxidizers and acids
Special Storage Requirements: Store in chemical resistant, clearly labeled containers with secondary containment as needed
Exposure Limits: No established occupational exposure limits
Engineering Controls: Use of mechanical exhaust ventilation, fume hood recommended

Polymerization: Not known to polymerize
Other Remarks: Exposure to air and light may affect color over time, extended contact with water can cause slow hydrolysis
Acute Toxicity: Limited data; low acute oral and dermal toxicity expected based on analogs
Skin Corrosion/Irritation: May cause mild to moderate irritation with prolonged or repeated contact
Serious Eye Damage/Irritation: Direct contact may cause redness and pain
Respiratory Sensitization: Dust, mist, or vapor inhalation may irritate upper airways
Skin Sensitization: Not known to cause skin sensitization, though data is limited
Germ Cell Mutagenicity: Not tested
Carcinogenicity: Not listed by IARC or NTP
Reproductive Toxicity: Not established
Specific Target Organ Toxicity: No laboratory evidence to indicate organ-specific toxicity
Other Effects: Lack of data on long-term exposure or chronic health effects
Ecotoxicity: Information scarce; ionic liquids have shown moderate to high aquatic toxicity in some studies
Persistence and Degradability: Not readily biodegradable. Ionic liquids tend to persist in the environment
Bioaccumulation Potential: Likely low, due to high water solubility and molecular structure
Mobility in Soil: High solubility suggests mobility in aquatic and terrestrial systems; risk of groundwater contamination
Other Hazards: Harm to aquatic life with long-term effects cannot be excluded
Avoid Release To Environment: Prevent all unintended releases, collect and treat waste responsibly
Waste Treatment Methods: Dispose of through licensed chemical waste contractor
Product Disposal: Small amounts: absorb on inert material, place in chemical waste drum. Large quantities: collect in drums, treat as hazardous chemical waste
