EC No.: Not assigned
Inhalation: Move to fresh air, support breathing as needed, seek medical attention for persistent symptoms
Skin Contact: Remove contaminated clothing, rinse skin with plenty of water for 15 minutes, seek medical advice if irritation develops
Eye Contact: Flush eyes with water for at least 15 minutes while holding eyelids apart; remove contact lenses, seek immediate medical help
Ingestion: Rinse mouth, do not induce vomiting without medical advice, seek medical attention promptly
Notes for Physicians: Treat symptomatically, monitor for signs of respiratory distress or tissue damage, consider possible delayed hydrofluoric acid effects
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, foam; avoid water stream since hydrolysis may release corrosive byproducts
Unsuitable Extinguishing Media: Water jets
Special Hazards: Thermal decomposition can release toxic fumes including hydrogen fluoride and boron trifluoride
Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective suit
Additional Information: Cool tanks and containers with water spray from a safe distance to prevent pressure build-up and potential explosion
Personal Precautions: Evacuate unnecessary personnel, ventilate area, wear chemical splash goggles, gloves, lab coat, and suitable respirators
Environmental Precautions: Prevent entry into drains, surface waters, and soil; inform authorities where significant spills enter the environment
Clean-Up Methods: Contain spill with inert absorbent (vermiculite, sand), collect in sealable containers for disposal, wash area down with plenty of water after removal
Disposal: Place contaminated absorbents into suitable waste containers, handle according to local, regional, and national waste regulations
Safe Handling: Avoid breathing vapors, dust, or mists; use only inside well-ventilated areas with suitable local exhaust; wear suitable chemical-resistant gloves and goggles; use tools and equipment that prevent sparking
Storage: Store in corrosion-resistant containers, keep tightly sealed in cool, dry, and well-ventilated area, away from moisture, strong acids, and bases
Incompatible Materials: Water, strong oxidizers, strong bases, reactive metals
Precautions: Keep away from sources of ignition, static electricity, and incompatible chemicals
Engineering Controls: Work in fume hood or with adequate local exhaust ventilation; use explosion-proof equipment in case of large-scale storage
Occupational Exposure Limits: No specific limits set for this material; follow common industrial hygiene practices

Serious Eye Damage/Irritation: Risk of severe irritation, redness, blurred vision, possible corneal damage
Respiratory Effects: Inhalation may result in coughing, throat irritation, or distress
Chronic Effects: Prolonged or repeated exposure may aggravate existing lung, skin, or eye conditions
Carcinogenicity: No reliable animal data available; not listed by IARC, NTP, ACGIH
Mutagenicity: No data available; structurally related compounds have no widespread evidence of mutagenicity
Reproductive Toxicity: No data available from published studies
Other Health Hazards: Hydrolytic breakdown may release hydrogen fluoride, which can penetrate skin and cause systemic toxicity
Aquatic Toxicity: Limited data; ionic liquids can be toxic to aquatic life depending on concentration and local conditions
Persistence and Degradability: Not readily biodegradable; long-term persistence possible in soil and water
Bioaccumulation: Potential for bioaccumulation low due to ionic nature and water solubility, but cation or anion may persist
Mobility in Soil: Likely to leach through soil into groundwater due to high solubility in water
Other Adverse Effects: Release of hydrolysis products may increase toxicity; avoid discharge to environment
