Advice for Firefighters: Approach fire from upwind, avoid inhaling fumes, cool containers with water if exposed to flames
Personal Precautions: Equip with gloves, goggles, protective clothing, and a respirator for vapor or dust exposure
Environmental Precautions: Prevent spillage from entering drains, sewers, and waterways
Cleanup Procedures: Absorb with inert material such as sand or vermiculite, collect into airtight containers for safe disposal, ventilate area
Handling: Avoid direct contact with skin and eyes; handle only in well-ventilated settings; employ standard chemical hygiene practices
Storage: Store in a tightly sealed, corrosion-resistant container, in a cool, dry, well-ventilated place, away from strong oxidizers and moisture
Incompatible Materials: Strong acids, strong bases, oxidizing agents, water or moisture
Engineering Controls: Operate under fume hood or with local exhaust ventilation
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile, PVC), splash-proof goggles, lab coat, and in case of risk of inhalation, an organic vapor respirator
Hygiene Measures: Wash hands before breaks and at end of shift, avoid eating, drinking, or smoking in work areas
Exposure Limits: No specific limits set by OSHA or ACGIH, but minimize exposure as a precaution
Appearance: Colorless to pale yellow liquid
Odor: Faintly aromatic

Acute Toxicity: Harmful if swallowed; estimated oral LD50 in rats: >300 mg/kg
Skin Corrosion/Irritation: Causes irritation on contact
Serious Eye Damage/Irritation: Triggers strong irritation
Respiratory Sensitization: Possible irritation of the respiratory tract on inhalation of vapors or mists
Chronic Effects: No evidence of carcinogenicity, reproductive, or mutagenic effects reported based on existing data
Additional Information: No detailed long-term animal data; prudent approach advised due to structural similarity with other ionic liquids
Ecotoxicity: Toxic to aquatic organisms; potential harmful effects on aquatic life through both acute and chronic exposure
Persistence and Degradability: Likely to persist in soil and water for extended periods; slow abiotic and biotic degradation
Bioaccumulative Potential: Moderate potential to bioaccumulate in aquatic species
Mobility in Soil: Low mobility, but potential for water contamination if spilled
Other Adverse Effects: Byproducts upon breakdown include fluorinated compounds and imidazolium residues; possible risk of long-term disruption to sensitive ecosystems
