Additional Information: Remove containers from fire area if it is safe, cool sealed containers with water to prevent rupture, avoid inhalation of combustion products
Personal Precautions: Evacuate unnecessary personnel, ventilate area, wear proper personal protective equipment such as gloves, goggles, and a chemical-resistant apron
Environmental Precautions: Prevent uncontrolled release into waterways, sewers, and soil
Containment Methods: Collect spillage, use non-combustible absorbent materials such as sand or earth, transfer to labeled waste container
Cleaning Procedure: Rinse area with plenty of water, ensure area is fully decontaminated, dispose cleanup materials according to local and national regulations
Handling: Use in well-ventilated setting, keep away from skin, eyes, and clothing, avoid breathing vapors or mist, wash thoroughly after handling
Storage: Store in tightly closed containers, keep in a cool, dry place out of direct sunlight, segregate from oxidizers and strong acids, use secondary containment to prevent leaks
Incompatible Materials: Strong bases, oxidizers, moisture, amines
Packaging Materials: Use containers made of compatible plastics or glass, ensure closures are secure to avoid leakages
Engineering Controls: Work in chemical fume hood or with adequate local exhaust ventilation
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), goggles or safety glasses with side shields, long-sleeved lab coat, recommended to use chemical-resistant apron in case of splashing
Respiratory Protection: Use NIOSH-approved respirator if ventilation is poor or operations generate dust, vapor, or spray
Hygiene Measures: Wash hands, forearms, and face thoroughly after use, avoid eating, drinking, or smoking when handling the material, regularly inspect protective gear

Hazardous Decomposition Products: Hydrogen fluoride, nitrogen oxides, sulfur oxides, carbon monoxide, carbon dioxide
Polymerization: No hazardous polymerization expected under recommended conditions
Acute Toxicity: Limited toxicity data for this ionic liquid; studies suggest moderate oral and dermal toxicity in laboratory animals
Skin Contact: Repeated exposure causes moderate irritation, no evidence of sensitization
Eye Contact: Causes redness, inflammation, watering, may induce corneal damage if not washed promptly
Inhalation: May cause respiratory tract irritation, prolonged exposure to high concentrations produces cough and discomfort
Ingestion: May produce gastrointestinal discomfort, nausea, and mild systemic toxicity at higher doses
Chronic Effects: No evidence of carcinogenicity or mutagenicity available from published studies
Potential Health Effects: Not classified as reproductive toxin, precaution recommended for pregnant women due to lack of extensive human data
Aquatic Toxicity: Demonstrated toxicity to aquatic organisms, especially in chronic exposure scenarios
Persistence and Degradability: Not readily biodegradable, remains in environment for extended periods
Bioaccumulation: Potential for moderate bioaccumulation based on structure, though measured partition coefficients vary
Mobility in Soil: Moderate, can migrate in soil environments, risk of leaching to groundwater if uncontrolled release
Other Adverse Effects: Do not allow chemical to reach sewage or watercourses, high toxicity concern due to fluorinated components
Waste Disposal Method: Dispose contents and container in accordance with local, regional, and national regulations for hazardous chemical waste
