CAS Number for Main Component: 779336-74-6
Concentration: 99% or greater for main ionic liquid
Impurities: Small percentages of unreacted starting materials or hydrolysis byproducts, typically less than 1%
Inhalation: Move person to fresh air, monitor breathing, seek medical attention if symptoms appear persistent or severe
Skin Contact: Remove contaminated clothing, wash skin with soap and water, seek medical attention if irritation continues
Eye Contact: Rinse eyes with water for at least 15 minutes, remove contact lenses if present and easy, continue flushing and seek prompt medical aid
Ingestion: Rinse mouth, do not induce vomiting, obtain immediate medical attention
Most Important Symptoms: Burning, redness, cough, headache, nausea, dizziness, eye watering
Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide
Specific Hazards: Product decomposes to release toxic and corrosive fumes of hydrogen fluoride, sulfur oxides, and nitrogen oxides
Protective Equipment: Firefighters wear self-contained breathing apparatus (SCBA) and protective clothing
Advice for Firefighters: Move containers from fire if safe, use water to keep containers cool, prevent runoff to waterways
Personal Precautions: Don suitable protective clothing, gloves, safety goggles, avoid inhalation, ventilate area
Environmental Precautions: Prevent release into drains, sewers, or waterways
Clean-Up Methods: Absorb with inert material such as sand or earth, shovel up for proper disposal, wash down spill area with copious water, ventilate space
Special Considerations: Isolate area, restrict access, inform safety personnel
Precautions for Safe Handling: Use only in well-ventilated areas, avoid contact with skin and eyes, avoid inhalation, keep away from sources of ignition, use spark-proof tools
Conditions for Safe Storage: Store in a tightly sealed container, keep in cool, dry, well-ventilated area away from strong acids, bases, and oxidizers
Incompatibilities: Strong oxidizing agents, acids, moisture
Storage Temperature: Room temperature, away from direct sunlight or heat sources
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits
Personal Protective Equipment: Safety goggles/face shield, chemical-resistant gloves, lab coat, respiratory protection if airborne exposure risk exists
Hygiene Measures: Wash hands after handling, no eating or drinking in the work area, promptly remove contaminated clothing and wash before reuse
Environmental Controls: Use closed systems whenever practical to avoid environmental release

Respiratory Sensitization: Irritates mucous membranes and respiratory tract
Chronic Effects: No long-term effects documented; limited data available
Carcinogenicity/Mutagenicity/Reproductive Toxicity: No classification data available
Aquatic Toxicity: Toxic to aquatic life due to the presence of fluorinated sulfonyl imide anion; avoid environmental release
Persistence and Degradability: Organic and inorganic components degrade slowly, long persistence in water and soil
Mobility: Expected to have moderate mobility in soil and water
Bioaccumulation: Components may accumulate in aquatic organisms to some degree; toxicological effects in the environment are not fully assessed
Other Adverse Effects: May contribute to chemical pollution if not controlled
