Inhalation: Remove affected person to fresh air. Keep at rest. Seek medical attention for any persistent discomfort such as coughing, shortness of breath, or dizziness.
Skin contact: Remove contaminated clothing. Rinse skin immediately with copious amounts of water for at least 15 minutes. Seek medical attention for persistent irritation.
Eye contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing. Immediate medical attention recommended.
Ingestion: Rinse mouth with water if conscious. Do not induce vomiting unless instructed by medical personnel. Seek immediate medical attention.
Medical Notes: Treat symptomatically. Product can cause irritation to mucous membranes.
Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide.
Unsuitable Extinguishing Media: Avoid direct water jet as chemical may react and disperse.
Specific Hazards: Thermal decomposition forms toxic gases including hydrogen fluoride, boron trifluoride, carbon oxides, nitrogen oxides.
Protective Equipment: Firefighters wear self-contained breathing apparatus and full protective clothing.
Precautions: Cool exposed containers with water spray if safe to do so. Prevent runoff from reaching waterways. In enclosed fires, ventilate area.
Personal Precautions: Evacuate area of unprotected personnel. Use proper personal protective equipment: gloves, eye protection, lab coat, appropriate respirator if ventilation is inadequate.
Spill Response: Stop leak if possible without risk. Cover spill with inert absorbent (such as dry sand or vermiculite) and place in chemical waste container.
Environmental Precautions: Prevent entry into drains, sewers, basements, or confined areas. Notify authorities if contamination of environment occurs.
Cleanup Methods: Sweep or scoop up material carefully and place in appropriate waste disposal container. Use non-sparking tools. Wash spill site after material pickup is complete.
Handling: Avoid contact with skin, eyes, and clothing. Avoid breathing vapors or mists. Use only in well-ventilated areas. Wash hands thoroughly after handling. Use with appropriate PPE.
Storage: Store in a tightly closed container in a cool, dry, and well-ventilated place. Keep away from incompatible substances such as strong oxidizers, strong bases, and moisture.
Special Instructions: Keep container upright to prevent leakage. Avoid exposure to heat or direct sunlight. Label all containers clearly. Store separately from food and drink.
Occupational Exposure Limits: No established exposure limits for product. Maintain airborne levels to lowest practical levels.
Engineering Controls: Use chemical fume hood or equivalent local exhaust ventilation.
Personal Protective Equipment:
- Eye/Face Protection: Safety goggles with side-shields
- Skin Protection: Chemical-resistant gloves (nitrile or neoprene recommended); lab coat or long-sleeved garment

Hazardous Decomposition Products: Hydrogen fluoride, boron trifluoride, carbon oxides, nitrogen oxides when exposed to heat or during combustion
Polymerization: Product does not undergo hazardous polymerization
Acute Toxicity: Not classified as acutely toxic; ingestion, inhalation, or dermal exposure may cause moderate irritation.
Skin Corrosion/Irritation: Causes skin irritation upon contact. Prolonged or repeated exposure can worsen effects.
Serious Eye Damage/Irritation: Causes severe eye irritation; potential for injury persists without timely flushing.
Respiratory Sensitization: Vapors can cause mild to moderate irritation of respiratory tract.
Chronic Effects: No long-term studies known, but repeated overexposure may cause dermatitis or aggravate existing skin/eye/respiratory conditions.
Carcinogenicity: Not listed as a carcinogen by IARC, NTP, or OSHA.
Mutagenicity / Reproductive Toxicity: No data available.
Other Information: No evidence for aspiration hazard. Allergic reactions rare but possible in sensitive individuals.
Ecotoxicity: Water toxicity data limited; similar ionic liquids can show moderate aquatic toxicity (EC50 >10 mg/L but <100 mg/L). Can persist in environment if released uncontrolled.
Persistence/Degradability: Poor biodegradability typical for tetrafluoroborate-containing ionic liquids; environmental breakdown slow.
Bioaccumulative Potential: Potential for accumulation in aquatic organisms not fully studied; typically considered low for similar compounds.
Mobility in Soil: High water miscibility leads to elevated mobility in soil and potential leaching to groundwater.
Other Adverse Effects: Release into environment should be minimized due to possibility of fluoride and boron ion release, both of which can be toxic at elevated levels.
Waste Treatment Methods: Collect and dispose at licensed chemical disposal contractor. Do not pour into drains or release into environment.
Contaminated Packaging: Empty containers should be rinsed and offered for recycling or disposal according to local regulations.
Additional Advice: Follow all local, regional, and national regulations for disposal of hazardous chemical waste. Consult environmental authorities about disposal of significant quantities.
Deactivation Methods: Do not attempt neutralization without proper chemical knowledge and authority approval.
Proper Shipping Name: Not regulated as dangerous goods under most international transport regulations (IATA, ADR, IMDG), but check local rules.
