General Advice: Move affected person to fresh air; call emergency medical services if symptoms persist
Eye Contact: Rinse eyes thoroughly with water for at least 15 minutes; remove contact lenses if present and easy to do
Skin Contact: Remove contaminated clothing; rinse skin immediately with soap and plenty of water; seek medical attention for continued irritation
Inhalation: Move person to fresh air and keep comfortable; get medical advice if respiratory symptoms develop
Ingestion: Rinse mouth; never give anything by mouth to an unconscious person; seek immediate medical attention
Suitable Extinguishing Media: Use foam, CO2, dry chemical, or water spray
Unsuitable Extinguishing Media: Avoid high-pressure water jets
Specific Hazards: May release corrosive vapors such as hydrogen fluoride, sulfur oxides, nitrogen oxides, and trifluoromethanesulfonic acid under fire conditions
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and chemical protective clothing
Special Firefighting Procedures: Cool exposed containers with water spray to prevent pressure buildup; evacuate area if fire holds risk of explosion; prevent runoff from butting into water sources
Personal Precautions: Evacuate unnecessary personnel; ventilate area; use suitable PPE including gloves, goggles, and respiratory protection
Spill Clean-Up Methods: Absorb with inert materials such as sand or vermiculite; sweep up and place in suitable containers for disposal
Environmental Precautions: Prevent entry into drains, sewers, waterways, or soil; notify authorities if spill causes environmental contamination
Decontamination: Wash spill area with plenty of water after material removal; ensure proper ventilation during clean-up
Handling: Keep away from sources of ignition; ensure good ventilation and hygiene; avoid unnecessary contact along with ingestion or inhalation; use chemical fume hood for transfers
Storage Conditions: Store in cool, dry, well-ventilated area in tightly closed container; keep away from incompatible materials such as strong oxidizing agents, acids, or bases
Special Requirements: Regularly check containers for leaks; use corrosion-resistant shelving; store away from direct sunlight and moisture; maintain a spill control plan on site
Engineering Controls: Ensure lab has adequate ventilation; use local exhaust systems or chemical fume hoods
Personal Protective Equipment: Safety goggles, nitrile or butyl rubber gloves, lab coat, closed footwear
Respiratory Protection: Use approved respirators if exposure risk exists during handling or accidental release
Hygiene Measures: Wash hands thoroughly after handling; avoid eating, drinking, or smoking in areas where substance is handled; remove contaminated clothing and wash before reuse

pH (aqueous solution): Approx. 6–7
Partition Coefficient: Not determined
Decomposition Temperature: Above 180°C yields corrosive gases
Chemical Stability: Stable under normal temperatures and pressures, away from moisture and incompatible substances
Reactivity: Reacts with strong acids, bases, and oxidizers; may produce corrosive fumes upon decomposition
Hazardous Decomposition Products: Hydrofluoric acid, sulfur oxides, nitrogen oxides, trifluoromethanesulfonic acid
Conditions to Avoid: Elevated temperatures, moisture ingress, contact with incompatible chemicals
Polymerization: Product does not undergo hazardous polymerization
Acute Toxicity: Harmful if swallowed, inhaled, or absorbed through skin; limited quantitative data available for humans
Skin Corrosion/Irritation: May cause skin irritation with redness or discomfort
Serious Eye Damage/Irritation: Causes moderate to severe eye irritation
Respiratory Sensitization: Potential to cause irritation to respiratory tract
Other Effects: Prolonged or repeated exposure may lead to dermatitis or allergic reactions; no known carcinogenic, mutagenic, or reproductive hazards identified under present data
Chronic Effects: Long-term studies not available; based on similar compounds, chronic exposure risk considered low with strict handling
Ecotoxicity: Toxic to aquatic life with prolonged effects; chemical may bioaccumulate in aquatic organisms
Persistence and Degradability: Slowly biodegradable; ionic liquid species tend to persist in the environment excluding rapid breakdown
Bioaccumulation Potential: Applicable for some aquatic species depending on local conditions; data limited
Mobility in Soil: Highly mobile when spilled; can contaminate groundwater if not contained
Other Adverse Effects: Avoid release to natural waters since fluorinated sulfonates can disrupt aquatic food chains
Waste Treatment Methods: Dispose of material through properly permitted chemical waste program or incineration in accordance with local, state, and federal regulations
Container Disposal: Empty containers must be triple rinsed before recycling or disposal; avoid discharge into sewers and natural water bodies
Special Notes: Do not attempt to neutralize without expert advice; always consult regulatory body for guidance on disposal technique; document waste removal for audit purposes
UN Number: Consult national transport regulations (not universally classified)
