Inhalation: Move affected person to fresh air, rest in position comfortable for breathing, consult physician if symptoms continue
Skin Contact: Remove contaminated clothing, wash affected skin with plenty of soap and water, seek medical advice if irritation develops or persists
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, get medical attention if symptoms persist
Ingestion: Rinse mouth with water, do not induce vomiting, call poison control or seek medical help for further instructions
Suitable Extinguishing Media: Dry powder, foam, carbon dioxide, water spray (do not use water jet directly as it may spread the fire)
Specific Hazards: Decomposition may produce toxic fumes including hydrogen fluoride, sulfur oxides, nitrogen oxides, and carbon oxides
Protective Equipment: Firefighters wear self-contained breathing apparatus and full protective gear to prevent contact with skin and eyes
Special Precautions: Cool containers with water spray to prevent overheating, evacuate unnecessary personnel from area
Personal Precautions: Use personal protective equipment (gloves, goggles, lab coat), ventilate area, avoid contact with skin and eyes, avoid inhalation of vapors
Environmental Precautions: Prevent further leakage or spillage if safe to do, avoid discharge to drains, waterways, or soil
Methods for Clean-up: Absorb spill with inert material (sand, earth, diatomaceous earth), collect with non-sparking tools, place in a chemical waste container for disposal according to local regulations, wash area with water and detergents
Safe Handling: Work in well-ventilated area, prevent contact with skin, eyes, and clothing, wash hands thoroughly after handling, keep containers tightly closed
Storage Conditions: Store in a cool, dry, well-ventilated place away from direct sunlight or heat sources, segregate from strong oxidizing agents or strong acids
Packing Materials: Use chemical-resistant containers and secondary containment to prevent leaks
Incompatibilities: Strong oxidizers, bases, and reducing agents increase risk of hazard or degrade product
Exposure Limits: No specific occupational exposure limits established for this material, general local and national regulations apply
Engineering Controls: Work inside chemical fume hood or with adequate mechanical ventilation, use spill containment where feasible
Personal Protective Equipment (PPE): Wear chemical-resistant gloves (nitrile, neoprene), safety goggles or face shield, lab coat or apron, closed footwear
Hygiene Measures: Do not eat, drink, or smoke during use, wash hands after handling, remove contaminated clothing promptly and wash before reuse

Acute Toxicity: Low oral and dermal toxicity based on available literature, oral LD50 in rodents estimated above 2000 mg/kg
Skin Corrosion/Irritation: Causes mild to moderate irritation, prolonged contact may worsen effects
Serious Eye Damage/Irritation: Data points to risk of persistent burning sensation, tearing, and redness
Respiratory or Skin Sensitization: No sensitization data for this compound, similar imidazolium compounds have shown low potential for allergies

Carcinogenicity: No classification as carcinogen by IARC, NTP, or OSHA
Reproductive Toxicity: No evidence available suggesting reproductive risk
Specific Target Organ Toxicity (Single Exposure): High vapor concentrations may irritate respiratory tract
Aspiration Hazard: Not classified as aspiration hazard
Ecotoxicity: Harmful to aquatic life based on read-across from similar ionic liquids; aquatic toxicity data limited but indicates risk for fish, daphnia, and algae
Persistence and Degradability: Ionic liquids tend to show slow biodegradation, likely to persist under low-oxygen conditions
Bioaccumulative Potential: Low-moderate potential, partitioning to water expected
Mobility in Soil: Likely mobile, risk of leaching to groundwater cannot be excluded in case of large spill
Other Adverse Effects: Avoid uncontrolled release, ionic nature can impact aquatic populations
Waste Treatment Methods: Dispose through licensed specialized chemical waste contractors
Contaminated Packaging: Rinse and dispose of according to local hazardous waste protocols
Disposal Precautions: Do not release into drains, surface water, or soil, avoid landfill
