Eye Contact: Immediately rinse with large amounts of water for at least 15 minutes, keeping eyelids open, remove contact lenses if present and easy to do, seek medical attention promptly if irritation persists
Skin Contact: Remove contaminated clothing, wash affected area thoroughly with soap and water, seek medical attention if skin irritation occurs or persists
Inhalation: Move to fresh air, keep individual at rest in a position comfortable for breathing, get medical advice if respiratory symptoms develop
Ingestion: Rinse mouth with water, seek immediate medical attention, do not give anything by mouth to an unconscious person
Most Important Symptoms/Effects: Burning sensation, irritation of the skin or eyes, respiratory discomfort, abdominal pain if swallowed
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, alcohol-resistant foam, water spray (use caution due to risk of hazardous decomposition products)
Specific Hazards: Thermal decomposition creates corrosive and irritating gases, including phosphorous oxides, hydrogen fluoride, and imidazole derivatives
Firefighter Protective Equipment: Full protective clothing with self-contained breathing apparatus, prevent runoff from entering drains or water bodies
Special Procedures: If safe, remove containers from the area, cool containers with water spray even after fire is out
Personal Precautions: Use personal protective equipment, avoid contact with skin, eyes, or clothing, avoid breathing vapors or dust, ensure adequate ventilation
Environmental Precautions: Prevent further leakage or spillage if safe, avoid release to the environment, contain spillage and collect as much as possible using inert absorbent (sand, earth)
Cleanup Methods: Sweep up and shovel material into appropriate chemical waste container, flush spill area with water, collect contaminated water and dispose of as hazardous waste
Safe Handling: Avoid all unnecessary contact with material, avoid breathing dust, vapor, or mist from this substance, keep away from sources of ignition or open flame, use only in well-ventilated areas
Storage Conditions: Store in tightly closed container in a cool, dry place, keep away from direct sunlight, separate from incompatible substances such as strong oxidizers or acids, store at temperatures below 30°C (86°F)
Incompatibilities: Moisture, strong oxidizing agents, strong bases, hydrolyzes slowly in presence of water producing hydrofluoric acid
Engineering Controls: Use process enclosures and local exhaust ventilation, maintain workplace concentrations below recommended exposure limits where available
Personal Protection Equipment: Protect eyes with safety goggles or face shield, wear chemical-resistant gloves (nitrile, neoprene), protect skin with lab coat or apron, if vapor or aerosol generation risk, use an approved respirator
General Hygiene: Wash hands thoroughly after handling, remove contaminated clothing immediately, do not eat, drink or smoke in work area

Decomposition Temperature: Above 200°C (392°F)
Chemical Stability: Stable under recommended storage conditions and normal temperatures
Reactivity: Slowly hydrolyzes in water, forming hydrofluoric acid and related compounds
Hazardous Reactions: Violent reaction with strong oxidizers, exposure to strong bases or acids can release hazardous gases
Thermal Decomposition: Yields toxic and corrosive vapors including phosphorous oxides, fluorides, imidazole derivatives
Incompatible Materials: Strong oxidizing or reducing agents, strong acids or bases, moisture
Routes of Exposure: Skin and eye contact, inhalation, ingestion
Acute Toxicity: Harmful if swallowed, may cause headaches, nausea, abdominal pain
Dermal Irritation: Possible redness, itching, irritation or burns
Eye Effects: Severe irritation, redness, pain, potential eye damage
Chronic Effects: Prolonged or repeated exposure can damage target organs including the liver and kidneys (data from related imidazolium salts)
Sensitization: Not classified as a sensitizer
Carcinogenicity/Mutagenicity/Reproductive Toxicity: Data insufficient, not classified as carcinogen; related materials show low mutagenic potential
Aquatic Toxicity: Toxic to aquatic organisms, potential for long-term adverse effects in aquatic environment
Persistence and Degradability: Not readily biodegradable; remains in environment for extended periods
Bioaccumulative Potential: Bioaccumulation not expected due to low water solubility, but data is incomplete
Mobility in Soil: Low mobility, binds to soil particles and sediments
Other Adverse Effects: Avoid contamination of waterways, soil or vegetation; no known destruction of ozone
Product Disposal: Dispose of in accordance with local, regional, and national regulations for hazardous waste; incineration at high temperatures in a facility with proper emission control methods
Contaminated Packaging: Triple rinse, then offer drum/barrel for proper reconditioning or disposal; avoid reuse
Environmental Cautions: Prevent material from entering sewers, drains, watercourses, or soil; consult hazardous waste disposal company
UN Number: Not assigned (verify with current regulations for ionic liquids)
ADR/RID/IMDG/IATA Classification: Not classified as dangerous goods under most international transport regulations due to low volatility; reclassification possible depending on quantity/concentration
Transport Hazards: Avoid unintentional release to environment, keep container upright and tightly closed, protect from mechanical damage during transport
Special Precautions: Transport with adequate labeling and documentation
EU Regulation: Not listed under REACH Authorisation, not listed as a Substances of Very High Concern
TSCA (US): Not listed in the Toxic Substances Control Act Inventory; handling subject to reporting
OSHA: Not specifically regulated; general chemical safety applies
