Inhalation: Move affected person to fresh air, seek immediate medical attention if discomfort persists, monitor for respiratory difficulties, oxygen may be administered by qualified personnel
Skin contact: Wash thoroughly with soap and water, remove contaminated clothing, seek medical advice if irritation develops or persists
Eye contact: Rinse cautiously with water for at least 15 minutes, lift eyelids to ensure thorough rinsing, seek medical attention as soon as possible
Ingestion: Rinse mouth with water, never give anything by mouth to an unconscious person, seek prompt medical attention, do not induce vomiting unless instructed by healthcare provider
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, alcohol-resistant foam
Unsuitable Extinguishing Media: Direct water jet may spread chemical
Specific Hazards Arising from Chemical: May produce toxic fumes such as carbon monoxide, nitrogen oxides, sulfur oxides, hydrogen fluoride, trifluoromethyl compounds upon combustion
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and chemical-resistant full protective clothing
Specific Firefighting Procedures: Move containers away from fire area if safe, cool containers with water fog, avoid breathing smoke or fumes
Personal Precautions: Use protective gloves, goggles, and suitable clothing, do not touch or walk through spilled material, ensure proper ventilation
Environmental Precautions: Prevent discharge to drains or waterways, contain spill using absorbent materials such as inert sand, clay, or commercial absorbents
Methods for Cleanup: Scoop up released material, avoid dust generation, place in tightly sealed chemical-resistant containers for disposal, clean spill area thoroughly with soap and water
Handling: Use chemical fume hood or well-ventilated area, avoid inhaling dust or vapor, avoid contact with skin, eyes, and clothing, do not eat, drink, or smoke when handling this substance
Storage: Keep container tightly closed in cool, dry, and well-ventilated place, store away from moisture, strong oxidizers, strong bases, and direct sunlight, use original container with appropriate chemical labeling, monitor for buildup of static charge
Engineering Controls: Chemical-resistant fume hoods, local exhaust ventilation, isolated storage and handling area
Personal Protection: Chemical splash goggles, face shield for bulk quantities, nitrile or neoprene gloves, long-sleeved lab coat, chemical-resistant apron
Respiratory Protection: Use particulate or organic vapor respirators if exposure limit risk applies or ventilation is inadequate
Hygiene Measures: Wash hands thoroughly before eating, drinking, or leaving the work area, shower after handling large quantities, avoid touching face during use
Appearance: White to off-white crystalline powder
Odor: Odorless or very faint organic smell
Odor Threshold: Not determined
pH (1% solution): Neutral to slightly acidic
Melting Point: 130–150 °C (varies by purity and hydration)
Boiling Point: Decomposes before boiling
Flash Point: Not flammable below 100 °C
Flammability: Not classified as flammable, but can combust under certain conditions
Solubility: Soluble in polar organic solvents such as acetonitrile and methanol, low solubility in water
Density: 1.35–1.50 g/cm³
Vapor Pressure: Negligible at ambient temperature
Partition Coefficient (log Kow): Not available
Viscosity: Not applicable for solid; liquid form highly viscous
Decomposition Temperature: Above 200 °C with risk of hazardous gas evolution
Chemical Stability: Chemically stable under recommended storage and handling conditions
Reactivity: Incompatible with strong bases and oxidizing agents, hydrolyzes slowly in strongly acidic or basic conditions
Hazardous Decomposition: Hazardous gases produced at elevated temperatures include trifluoromethanesulfonyl fluoride, carbon oxides, nitrogen oxides, sulfur oxides
Polymerization: Not likely
Other Notes: Absorbs water from humid air over long exposures, container closure integrity important
Acute Toxicity: Oral LD50 (rat): Estimated between 300–1000 mg/kg, may cause stomach and intestinal irritation, nausea, vomiting
Skin Corrosion/Irritation: Causes moderate redness and irritation on contact
Serious Eye Damage/Irritation: Significant risk for irritation, redness, tearing
Respiratory Sensitization: May irritate mucous membranes upon inhalation
Chronic Health Effects: Long-term data lacking, but repeated high-level exposure might damage kidney or liver
Carcinogenicity: Not known to be carcinogenic
Mutagenicity: No evidence for DNA damage in limited studies
Reproductive Toxicity: No reproductive studies available
Other Health Hazards: Might worsen symptoms for people with skin conditions or asthma
Ecotoxicity: Harmful to aquatic life with long-lasting effects based on related ionic liquids, can persist in soil and groundwater
Persistence and Degradability: Not readily biodegradable, persistent organic ions may remain in the environment
Bioaccumulative Potential: Bioaccumulation unknown, but molecular structure suggests potential for slow breakdown
Mobility in Soil: Moves slowly through soil, may leach into groundwater under certain conditions
Other Adverse Effects: Further ecological studies needed for full hazard profile, avoid release to the environment
Waste Treatment Methods: Dispose as hazardous chemical waste in accordance with local, state, and national regulations, do not pour down drain or general waste
Contaminated Packaging: Containers should be triple rinsed, punctured, and managed as hazardous waste
Disposal Precautions: Incineration or chemical treatment may be suitable at authorized facilities, avoid open burning or uncontrolled releases
UN Number: Not assigned by UN yet; proper shipping name may be “Environmentally hazardous substance, solid, n.o.s.”
