If Ingested: Rinse mouth thoroughly with water. Do not induce vomiting unless directed by medical personnel. Contact poison control or a physician.
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical, carbon dioxide.
Special Hazards: Combustion produces hazardous fumes such as carbon monoxide, carbon dioxide, sulfur oxides, nitrogen oxides, hydrogen fluoride, toxic and corrosive gases.
Advice for Firefighters: Wear self-contained breathing apparatus and full protective gear. Avoid inhalation of vapors and combustion products. Prevent runoff from entering drains or watercourses.
Specific Firefighting Procedures: Use standard procedures for chemical fires. Cool exposed containers with water spray.
Personal Precautions: Evacuate area. Ensure adequate ventilation. Remove all sources of ignition. Use recommended personal protective equipment. Avoid contact with skin and eyes. Do not breathe vapors, mist, or dust.
Methods for Cleanup: Absorb spills with inert material such as dry sand or earth. Place in chemical waste container for proper disposal. Clean spill area with soap and water. Avoid runoff into sewers and waterways.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not allow to enter soil, drains, surface water or groundwater.
Handling: Avoid contact with skin, eyes, and clothing. Use only with adequate ventilation. Wear suitable personal protective equipment. Do not eat, drink, or smoke while using. Wash thoroughly after handling. Prevent generation of dust and aerosols.
Storage: Store in a tightly closed container in a cool, dry, well-ventilated area away from incompatible substances such as strong oxidizing agents, acids, and bases. Protect from moisture and direct sunlight. Prevent contamination.
Storage Class: Chemically stable organic compounds, non-combustible in bulk but may emit toxic fumes on decomposition.
Occupational Exposure Limits: No specific occupational exposure limits established. Follow good industrial hygiene practices.
Engineering Controls: Work with adequate ventilation such as chemical fume hood. Use local exhaust if necessary. Regularly inspect ventilation for proper function.
Personal Protective Equipment: Wear protective clothing, gloves resistant to chemical exposure (e.g., nitrile), chemical safety goggles, and if airborne concentrations are high, use respiratory protection (NIOSH/MSHA approved cartridge respirators).
Hygiene Measures: Wash hands before breaks and after work. Keep clothing clean. Remove and launder contaminated clothing before reuse. Avoid contact with skin, eyes, and clothing.

Ecotoxicity: May be toxic to aquatic life with long lasting effects. LC50/EC50 values (aquatic organisms) not fully established but ionic liquids tend to demonstrate moderate persistence and toxicity in laboratory studies.
Persistence and Degradability: Product shows little evidence of rapid biodegradation; tends to persist under standard environmental conditions.
Bioaccumulative Potential: Potential for bioaccumulation in aquatic organisms, mobility depends on local conditions.
Mobility in Soil: Moves slowly in soil because of ionic nature, tends to adsorb to soil particles.
Other Adverse Effects: Avoid release to the environment. Mined data from related substances indicates ionic liquids may disrupt wastewater treatment at higher concentrations.
Waste Treatment Methods: Dispose of product, residues, and contaminated packaging via licensed chemical waste disposal contractor. Follow local, regional, and national regulations.
