Eye Contact: Rinse eyes thoroughly with water for several minutes, remove contact lenses if present and easy, continue rinsing, seek medical attention if irritation persists
Skin Contact: Wash affected skin area with soap and plenty of water, remove contaminated clothing, seek medical attention if irritation develops
Inhalation: Remove person to fresh air, keep comfortable for breathing, seek medical care if symptoms like coughing or shortness of breath continue
Ingestion: Rinse mouth, do not induce vomiting, give water if conscious, seek immediate medical guidance
Acute/Delayed Symptoms: Minor irritation for most healthy adults, pre-existing conditions may heighten sensitivity
Suitable Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or foam extinguishers
Special Hazards: Thermal decomposition can produce toxic fumes, including nitrogen oxides, hydrogen bromide, and carbon monoxide
Protective Equipment for Firefighters: Wear self-contained breathing apparatus, full protective gear, avoid inhaling combustion by-products
Advice for Firefighters: Move containers from fire zone if safe, cool exposed containers with water spray, avoid runoff into drains
Personal Precautions: Wear gloves, eye protection, avoid contact with skin and eyes, ventilate area
Environmental Precautions: Prevent large spills from entering sewers or waterways, report as required by local regulations
Cleanup Methods: Absorb spillage with inert material (sand, vermiculite), collect in suitable containers for disposal, thoroughly ventilate area, wash contaminated area with soap and water
Handling: Use in well-ventilated area, avoid direct contact, practice good chemical hygiene, avoid eating or drinking during use, keep containers closed when not in use
Storage: Store in a tightly sealed container in a cool, dry, well-ventilated location, avoid excessive heat or direct sunlight, keep away from strong oxidizing agents and water-sensitive materials
Special Precautions: Use secondary containment for large quantities, keep incompatible materials separated
Occupational Exposure Limits: No established limits available for this compound
Engineering Controls: Use chemical fume hood or adequate local exhaust, eyewash and safety shower nearby

Carcinogenicity: Not listed as carcinogenic by IARC, NTP, or OSHA
Reproductive Toxicity: No data available
STOT (Specific Target Organ Toxicity) – Single Exposure: Possible mild respiratory irritation
STOT – Repeated Exposure: No data; avoid chronic exposure as a precaution
Aspiration Hazard: Not expected to present aspiration risk
Acute Aquatic Toxicity: Information limited, ionic liquids often show some aquatic toxicity, handle to avoid environmental release
Chronic Aquatic Toxicity: Potential for persistence and bioaccumulation not established, some ionic liquids can be toxic to aquatic life with long-lasting effects
Mobility in Soil: Expected to be mobile in water due to high solubility
Persistence and Degradability: Data not available, suggest limiting environmental exposure
Bioaccumulation Potential: Not likely due to ionic character, but testing is incomplete
Other Adverse Effects: Do not allow large quantities to enter waterways or soil
Waste Disposal Methods: Dispose as hazardous chemical waste, follow local, state, and national regulations for chemical disposal, use approved waste management service
Contaminated Packaging: Rinse empty containers, dispose of as chemical waste, do not reuse containers for food or animal feed
Other Precautions: Do not flush to sewer, avoid release to environment, consult chemical waste disposal facility for detailed guidance
