Inhalation: Move to fresh air. Seek medical attention if coughing, shortness of breath, or adverse effects continue. Remove contaminated clothing and loosen any tight clothing items.
Skin contact: Rinse immediately with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Seek medical attention if irritation persists.
Eye contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy. Continue rinsing. Get medical attention for persistent irritation.
Ingestion: Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Get medical help immediately.
Important symptoms: Burning sensation, redness, itchiness, respiratory distress may appear depending on exposure.
Suitable extinguishing media: Water spray (fog), dry chemical, foam, carbon dioxide
Unsuitable extinguishing media: Strong water jet, which may cause chemical spread
Hazardous combustion products: Nitrogen oxides, hydrogen cyanide, carbon oxides, toxic and irritating fumes
Personal protective equipment: Firefighters require self-contained breathing apparatus and full protective gear. Avoid inhalation of sensitive combustion fumes.
Specific hazards: Closed containers can explode under high heat. Avoid runoff from firefighting that can enter water bodies and drain systems.
Personal precautions: Use proper personal protective equipment, prevent skin and eye contact, ensure adequate ventilation
Environmental precautions: Prevent further leakage or spillage if safe to do, do not let chemical enter drains, surface water, or soil
Containment: Absorb with inert material (sand, earth, chemical absorbent pad), collect with non-sparking tools, and place in suitable containers for disposal
Cleaning methods: Ventilate area, wash contaminated surfaces with water and detergent, keep waste out of water systems and handle as hazardous waste.
Precaution for safe handling: Wear chemical resistant gloves, goggles, lab coat. Use appropriate exhaust ventilation. Keep containers tightly closed. Avoid inhaling dust or vapor. Avoid contact with skin, eyes, and clothing.
Conditions for safe storage: Store in cool, dry, well-ventilated location, away from direct sunlight and incompatible substances such as oxidizing agents and acids. Keep containers tightly sealed when not in use. Store away from heat sources or ignition points.
Special handling guidelines: Follow good hygiene practices. Do not eat or drink near chemical work areas. Ensure storage areas allow for containment of spills.
Occupational exposure limits: No specific limits established, but minimize all exposure
Engineering controls: Use fume hood or local exhaust where vapor might arise. Eye-wash stations and safety showers necessary.
Personal protective equipment: Chemical-resistant gloves (nitrile or neoprene), splash protection goggles, lab coat, closed shoes
Respiratory protection: Use NIOSH-approved respirator if ventilation insufficient or significant vapor/dust present
Hygiene measures: Wash hands thoroughly with soap after handling. Remove contaminated clothing before leaving work area.

Skin corrosion/irritation: Can cause irritation, especially with prolonged contact
Eye damage/irritation: Irritation, redness, pain possible
Respiratory/skin sensitization: No data available on sensitization, avoid repeated/prolonged exposure
Genotoxicity/carcinogenicity: No data available, not classified by major agencies
Other effects: In some cases, central nervous system effects observed with high exposures; take precautionary measures
Toxicity to aquatic organisms: Acutely toxic to aquatic invertebrates and fish at certain concentrations
Persistence and degradability: Limited data, but ionic liquids may be slowly biodegradable or persistent in the environment
Bioaccumulative potential: Low to moderate based on structure and water solubility
Mobility in soil: Mobile in aqueous environments, potential to leach to ground water
Other adverse effects: Prevent chemical from entering waterways; even small quantities may upset local ecosystems
Waste treatment methods: Dispose of in accordance with local, regional, national, and international regulations
Disposal of substance: Take unwanted and contaminated product to licensed chemical disposal facility. Do not dispose in sewer, drain, or natural waterways.
Contaminated packaging: Triple rinse containers before disposal or recycling. Handle packaging as hazardous waste unless fully cleaned.
