Ingestion: Rinse mouth thoroughly, drink water if conscious, do not induce vomiting unless instructed by medical personnel, call physician or Poison Control Center
Most Important Symptoms: Local irritation, redness, coughing, sore throat, chemical burns are unlikely but possible after heavy exposure
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, or water spray
Specific Hazards: Product does not burn easily, but thermal decomposition may generate toxic fumes including nitrogen oxides and acetic acid
Protective Equipment: Wear self-contained breathing apparatus, chemical-resistant suit
Special Procedures: Cool closed containers exposed to fire with water, avoid breathing fumes
Personal Precautions: Use chemical-resistant gloves and safety goggles, avoid all skin and eye contact
Environmental Precautions: Prevent spillage from entering drains, watercourses, or soil
Methods for Containment: Absorb with inert material like sand or diatomaceous earth, transfer residue to secure labeled container, ventilate area
Clean-up Procedures: Wash spill area with soap and water, dispose of cleanup materials according to local regulations
Handling: Work in a chemical fume hood or with local exhaust, avoid inhaling vapors, prevent direct skin or eye exposure, keep away from incompatible materials such as strong oxidizers
Storage: Store in a tightly sealed container, cool, dry, well-ventilated place, protect from heat and moisture, label clearly and segregate from food and incompatible chemicals
Technical Measures: Ground/bond container to prevent static discharge, have safety shower and eyewash station nearby
Engineering Controls: Local exhaust, fume hood, mechanical ventilation for enclosed spaces
Threshold Limit Value (TLV): Not established, work in well-ventilated setting
Personal Protective Equipment: Chemical-resistant gloves, splash goggles, lab coat or apron, respiratory protection where vapor concentrations exceed comfort levels
Hygiene Measures: Wash hands after handling, change contaminated clothing immediately, avoid eating or drinking near chemical
Appearance: Clear to pale yellow liquid
Odor: Mild, acetate-like
Melting Point: Typically below 0°C
Boiling Point: Decomposes, boiling point not well defined
Flash Point: >110°C (closed cup)
Solubility: Miscible with water and many organic solvents
Density: Approx. 1.06–1.10 g/cm³ at 25°C
pH: About neutral in aqueous solution
Viscosity: High relative to water, depending on temperature
Chemical Stability: Stable under recommended handling and storage conditions
Conditions to Avoid: Excessive heat, moisture, strong light, incompatible substances like strong oxidizers
Incompatible Materials: Strong acids, strong bases, oxidizing agents such as peroxides and nitrates
Hazardous Decomposition Products: Carbon oxides, nitrogen oxides, acetic acid fumes at high temperatures
Hazardous Polymerization: Not expected to occur
Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Toxicity: Information limited; estimated low to moderate toxicity based on related ionic liquids
Irritation: Risk of irritation to eyes, skin, and mucous membranes
Chronic Effects: Data insufficient, long-term studies have not established carcinogenic, mutagenic, or reproductive toxicity
Sensitization: Not reported, but minimize repeated exposure
Symptoms of Exposure: Irritation, discomfort, coughing, headache if inhaled in vapor form
Medical Conditions Aggravated: Pre-existing skin, eye, or respiratory conditions
Ecotoxicity: Specific aquatic toxicity data not fully available, ionic liquids can be hazardous to aquatic life if released in significant quantities
Persistence and Degradability: Likely to persist; many ionic liquids resist rapid degradation due to stable molecular structure
Bioaccumulation Potential: Not well studied; typically low, but caution warranted
Mobility in Soil: High water solubility can enhance mobility, possible contamination risk
Other Adverse Effects: Potential to disrupt aquatic microbial processes in large spills
Waste Treatment Methods: Dispose of material and residues through a licensed chemical waste contractor
Disposal Containers: Use clearly labeled, tightly sealed containers, segregate from non-hazardous waste
Sewage Disposal: Do not dispose via drains or waterways
Special Precautions: Handle waste as potential environmental hazard, observe all local and regional requirements
Contaminated Packaging: Rinse thoroughly before recycling or dispose through hazardous waste program
UN Number: Not assigned for this specific compound, shipping usually not regulated but verify with local authorities
Transport Hazard Class: Not classified as hazardous for purposes of road, rail, sea, or air transit unless mixed with other hazardous substances
Packing Group: Not specified
Special Transport Precautions: Protect from physical damage, keep container upright, follow loading/unloading precautions
