Inhalation: Move exposed person to fresh air, supply oxygen if available, monitor for breathing, seek professional medical evaluation for persistent symptoms such as coughing or wheezing
Skin Contact: Remove contaminated clothing, wash affected area with plenty of water and gentle soap, seek medical advice if irritation or redness persists
Eye Contact: Carefully rinse open eyes with clean water for at least fifteen minutes, avoid rubbing, consult an ophthalmologist if redness or pain does not subside quickly
Ingestion: Rinse mouth thoroughly, do not induce vomiting, seek prompt medical observation, display the product label or safety data when seeking help
Suitable Extinguishing Media: Use dry chemical powder, carbon dioxide, or alcohol-resistant foam, as water can spread chemical contamination
Special Firefighting Procedures: Wear full firefighting gear and self-contained breathing apparatus, avoid inhaling decomposition fumes, isolate hazard area and limit runoff
Hazardous Combustion Products: Hydrogen chloride, nitrogen oxides, carbon oxides
Unusual Fire Explosion Hazards: Thermal decomposition at elevated temperatures can release dense and corrosive fumes; fight fire from safe distance
Personal Precautions: Wear splash-proof goggles, impervious gloves, and laboratory coat or disposable coveralls
Environmental Precautions: Minimize entry into drains, ponds, or open waterways, block off spill pathways with absorbent booms
Cleanup Methods: Absorb small spills with sand, earth, or vermiculite; scoop into sealable containers for hazardous waste disposal, ventilate area, remove residues with detergent solution, follow up with a water rinse
Notification: Report significant spills to local authorities as required by regulations
Handling: Use in well-ventilated workspaces, keep containers closed except when dispensing, employ recommended personal protective equipment and avoid breathing dusts or vapors
Storage Conditions: Store in tightly sealed original containers, place in dry, cool, well-ventilated chemical stores, away from incompatible substances such as potent oxidizers or acids
Incompatibilities: Strong oxidizers, strong acids, moisture, high temperatures
Packaging Materials: Polyethylene, glass, or similar chemically resistant materials
Exposure Limits: Occupational exposure limits not established, but prudent practices suggest minimizing direct contact and inhalation
Engineering Controls: Fume hood or local exhaust ventilation for laboratory handling, properly rated general ventilation for industrial users
Personal Protective Equipment: Chemical splash goggles, nitrile or butyl rubber gloves, laboratory coat or chemical-resistant apron, closed footwear
Hygiene Measures: Wash hands, forearms, and face thoroughly after use; do not eat, drink, or smoke in chemical work areas; remove contaminated clothing before leaving workspace
Appearance: White to pale yellow crystalline powder or solid

Partition Coefficient (log Pow): Data not available
Auto-Ignition Temperature: Not auto-igniting
Decomposition Temperature: Above 180 °C
Viscosity: Moderate to high, varies with temperature and moisture
Molecular Structure: Ionic compound with delocalized cation and chloride anion
Chemical Stability: Stable under recommended handling and storage
Thermal Decomposition: Decomposes at elevated temperatures producing harmful vapors
Hazardous Reactions: Contact with strong oxidizers may cause rapid exothermic reaction
Conditions to Avoid: Prolonged exposure to moisture, high temperatures, direct sunlight
Materials to Avoid: Strong oxidizing agents, reducing agents, strong acids
Hazardous Decomposition Products: Hydrogen chloride, ammonia, oxides of nitrogen and carbon
Routes of Exposure: Inhalation, skin, eye, ingestion
Acute Toxicity: Oral LD50 values in rats exceed 2,000 mg/kg; low acute toxicity estimates based on animal studies
Skin Corrosion/Irritation: Causes redness, mild irritation on prolonged contact
Serious Eye Damage/Irritation: May cause stinging, tearing, or temporary redness
Respiratory Effects: May trigger coughing or minor irritation in poorly ventilated spaces or if powder is dispersed
Other Health Effects: Prolonged or repeated exposure can cause dermatitis in sensitive individuals; low aspiration risks
Carcinogenicity: Not listed by IARC, NTP, OSHA
Mutagenicity / Reproductive Effects: No definitive data available from long-term studies; chemical structure suggests low risk
Ecotoxicity: Limited data; ionic liquids in general have shown moderate aquatic toxicity in some model organisms, but low bioaccumulation in typical environments
Mobility in Soil: Soluble in water, likely to move through soil with percolating water
Persistence and Degradability: Not readily biodegradable; may persist in some environments, especially under anaerobic conditions
Bioaccumulative Potential: Low potential for bioaccumulation due to ionic structure
Other Adverse Effects: Avoid uncontrolled environmental release; effects on microbial communities remain under study
Waste Disposal Methods: Dispose of in accordance with local, regional, national, and international regulations for chemical waste; do not pour down drains or mix with organic waste streams; incineration or hazardous chemical disposal services often recommended
