Protective Equipment: Wear self-contained breathing apparatus and protective gear
Advice for Firefighters: Stay upwind, use full turnout gear, avoid inhalation of combustion residues
Hazardous Combustion Products: Toxic fumes including hydrogen cyanide, nitrogen oxides, carbon monoxide
Explosion Risk: No known risk of explosive reaction under normal fire conditions
Personal Protection: Use gloves, goggles, and chemical-resistant clothing
Environmental Precautions: Prevent entry into waterways, soil, or drains; stop further leakage if safe
Methods for Cleanup: Collect spilled material using inert absorbent (sand, vermiculite), place in sealed container for disposal
Ventilation: Ensure area is well-ventilated during cleanup work
Decontamination: Clean hard surfaces with detergent and plenty of water, avoid sweeping dry powder into air
Handling: Minimize dust and liquid aerosol formation, avoid contact with eyes or prolonged skin exposure, practice good hygiene (wash after handling and before eating), do not eat, drink, or smoke in processing area
Storage Conditions: Store below 30°C in cool, dry, well-ventilated area, keep container tightly sealed away from incompatible substances (strong acids, oxidizers), label and segregate chemicals appropriately
Storage Incompatibility: Do not store with acids, nitrates, oxidizing agents
Shelf Life: Maintain original container; check regularly for signs of leaks, color changes, or residue on containers
Exposure Limits: No established occupational exposure limits (consult local guidelines for ionic liquids)
Ventilation: Work in fume hood or well-ventilated area
Personal Protection: Nitrile gloves, chemical safety goggles, lab coat; where risk of splashes exists, use face shield
Respiratory Protection: Use NIOSH-approved respirator if dusts, mists, or aerosol concentrations reach nuisance levels
Hygiene: Remove contaminated clothing, wash thoroughly after exposure, maintain clean work environment
Engineering Controls: Use local exhaust or containment to minimize chemical exposure
Appearance: Colorless or pale yellow liquid; may appear viscous at room temperature
Odor: Characteristic faint organic odor
pH: Neutral to slightly basic in aqueous solution
Melting Point: Around -15°C
Boiling Point: Above 200°C (decomposes before boiling)
Flash Point: Not easily flammable; expected above 150°C
Vapor Pressure: Negligible at room temperature
Solubility: Miscible with water and polar organic solvents
Partition Coefficient (log Kow): Data not available, likely moderate due to ionic nature
Viscosity: Moderate to high viscosity depending on temperature
Chemical Stability: Stable under recommended storage and handling conditions
Conditions to Avoid: High heat, extreme exposure to light, strong oxidizers
Incompatible Materials: Acids, oxidizing agents, halogenated compounds
Decomposition Products: Hydrogen cyanide, nitrogen oxides, carbon monoxide, unidentified fragments possible on strong heating
Polymerization: Does not polymerize under normal conditions
Acute Toxicity: Data is limited, oral LD50 in rodents estimated to be >2,000 mg/kg
Skin Corrosion/Irritation: Prolonged exposure can lead to redness, mild irritation, potential for dermatitis
Eye Damage/Irritation: Causes slight irritation if splashed into eyes
Sensitization: No data indicating skin or respiratory sensitization
Chronic Toxicity: No long-term studies published; related compounds have demonstrated low-level organ effects in repeated-dose non-human studies
Carcinogenicity/Mutagenicity/Reproductive Toxicity: Not listed by IARC, NTP, or OSHA; no evidence found
Possible Routes of Exposure: Inhalation, dermal absorption, ingestion, ocular
Toxicity: Knowledge about ecological effects is incomplete; related ionic liquids have shown moderate toxicity to aquatic organisms at high concentrations
Persistence: Likely to persist in natural waters; slow degradation expected
Bioaccumulation: No information indicating strong bioaccumulation potential
Mobility: Dissolves readily, may contaminate water resources if released uncontrolled
Aquatic Impact: Limiting environmental discharge is best practice due to unknown fate and potential aquatic toxicity
Waste Treatment Methods: Follow local and national regulations for chemical waste; hand over to professional chemical disposal contractor
Container Disposal: Rinse empty containers with water, dispose as hazardous laboratory chemical waste, never reuse unwashed containers
Do Not: Release into sewage system, storm drains, or natural bodies of water
Precaution: Document disposal in chemical inventory logs, retain receipts for regulatory records
UN Number: Not assigned
Transport Class: Not regulated under ADR/RID, IMDG, IATA; check for updates or local requirements
Packing Group: Not allocated
Transport Precautions: Secure tightly in upright sealed containers, avoid excessive heat, cushion against impact, include clear hazard labeling
Emergency Procedures: Carry documentation of chemical contents, MSDS available for emergency responders
Special Requirements: Not required under most jurisdictions though voluntary hazard communication is strongly advised
Safety, Health, and Environmental Regulations: Product not specifically listed under TSCA, REACH, or SARA Title III; supplier notifies end users of updates
Labeling: Not classified under GHS as hazardous but precautionary labeling is considered good laboratory practice
