Inhalation: Remove to fresh air, provide rest, seek medical attention if symptoms continue
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, seek attention for persistent symptoms
Eye Contact: Rinse immediately with plenty of water, keep eyes open, seek medical care if irritation continues
Ingestion: Rinse mouth, drink water, do not induce vomiting, contact a physician right away
Suitable Extinguishing Media: Foam, carbon dioxide (CO₂), dry chemical, or water spray
Unsuitable Extinguishing Media: Direct water jet may spread burning liquid
Special Hazards: Emits toxic fumes of boron and fluorine during combustion, may also produce nitrogen oxides and carbon oxides
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective suit, approach upwind
Further Advice: Move containers away if safe, use water spray to cool exposed drums or tanks
Personal Precautions: Wear chemical splash goggles, impervious gloves, use a fume hood or ensure ventilation
Environmental Precautions: Stop further leakage, prevent release into water systems, collect spills with inert material
Cleanup Methods: Collect by scooping, absorb with vermiculite/sand, transfer to sealed container for disposal
Decontamination: Wash area with soap and water, avoid flushing into drains
Reporting: Notify authorities if large spill impacts natural environment
Handling: Avoid direct skin or eye contact, work in properly ventilated space, keep container tightly closed after use
Safe Practices: Use non-sparking tools, ground containers during transfer to prevent static
Storage Conditions: Store in original, clearly labeled, tightly closed container, cool dry location, away from incompatible materials like strong oxidizers, moisture, acids, or bases
Storage Temperature: Ambient, avoid temperature extremes or direct sunlight
Segregation: Hold away from food, feed, and water sources
Engineering Controls: Use chemical fume hood, provide local exhaust ventilation around processes
Personal Protective Equipment (PPE): Wear chemical splash goggles or face shield, disposable gloves (nitrile), lab coat, and possibly apron
Hand Protection: Nitrile or neoprene gloves
Respiratory Protection: If ventilation lacking or risk from vapor, use approved half-mask respirator
Hygiene Measures: Wash thoroughly after handling, take off contaminated clothing and wash before reuse

Vapor Density: Not determined
Relative Density: 1.07–1.12 (water = 1)
Solubility: Slightly soluble in water, miscible in many organic solvents
Partition Coefficient (log Kow): Not available
Auto-ignition Temperature: Not self-igniting under ordinary conditions
Decomposition Temperature: 250–300°C
Viscosity: Moderate to high for ionic liquid—often higher than conventional solvents
Chemical Stability: Stable under recommended handling, may decompose at elevated temperatures
Reactivity: No hazardous polymerization expected
Incompatible Materials: Strong oxidizers, moisture, acids, bases
Hazardous Decomposition Products: Hydrogen fluoride, boron oxide, carbon monoxide, carbon dioxide, other toxic gases possible upon heating
Conditions to Avoid: Excess heat, direct sunlight, humid conditions
Acute Toxicity: No data for LD₅₀ in animals; similar imidazolium ionic liquids can cause moderate toxicity by ingestion and skin exposure
Skin Corrosion/Irritation: Causes moderate skin irritation
Serious Eye Damage/Irritation: Causes noticeable eye irritation, redness, watering
Respiratory Sensitization: No specific data, but inhalation of spray/vapor can irritate airways
Ingestion Effects: Discomfort, nausea, gastrointestinal pain
Chronic Effects: Repeated or prolonged contact can dry or crack the skin
Carcinogenicity/Mutagenicity: No data to indicate; not listed by IARC, NTP, or OSHA
Potential Routes of Exposure: Dermal, ocular, oral, inhalation exposure possible in laboratory or manufacturing scenarios
Ecotoxicity: Harmful to aquatic organisms at low concentrations, persistent in aquatic systems
Persistence and Degradability: Likely to resist rapid biodegradation; potential for slow natural breakdown
Bioaccumulative Potential: Some potential due to lipophilic side chain — risk of aquatic food chain accumulation
Mobility in Soil: Limited mobility due to moderate water solubility; may leach slowly
Wastewater Impact: Discharge into drains or waterways should be controlled as it may stress aquatic life
Additional Information: Monitor any environmental release and seek methods to minimize emissions
Disposal Methods: Collect in sealable, labeled waste drums; treat as hazardous chemical waste
Incineration: Permitted at proper facilities with flue gas scrubbers
Reuse/Recycling: Not recommended for direct disposal in local landfills or sewage
