Inhalation: Move person to fresh air; provide artificial respiration or oxygen if needed. Seek medical attention if symptoms develop.
Skin Contact: Remove contaminated clothing, flush skin with plenty of water for at least 15 minutes. Tag symptoms including redness and irritation. Seek medical attention for persistent effects.
Eye Contact: Immediately flush eyes with large amounts of water for at least 15 minutes, lifting upper and lower eyelids occasionally. Remove contact lenses if present and safe to do so. Get medical attention right away.
Ingestion: Rinse mouth with water. Do not induce vomiting unless directed by medical personnel. Drink water to dilute. Immediate medical attention is recommended, especially if symptoms appear.
Major Symptoms: May include headache, dizziness, nausea, respiratory distress, skin and eye redness.
Advice for Rescuers: Use personal protective equipment to avoid chemical exposure.
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam or water spray. Choose agents based on the surrounding fire.
Unsuitable Media: Direct water jet not recommended as it may spread chemical.
Specific Hazards: Toxic fumes of phosphorus oxides, hydrogen fluoride, and nitrogen oxides released during combustion. Combustion may release hazardous decomposition products.
Special Equipment: Firefighters require self-contained breathing apparatus and full protective gear.
Firefighting Methods: Remove unaffected containers from area if safe; use water spray to cool surfaces exposed to fire.
Personal Precautions: Wear appropriate personal protective equipment including gloves and safety glasses. Avoid breathing vapors or dust, prevent eye and skin contact.
Environmental Precautions: Prevent release into sewers, surface water, or groundwater. Alert authorities if chemical enters environment.
Cleaning Methods: Contain and collect spillage with absorbent material (sand, earth, vermiculite), transfer to suitable, labeled waste container. Ventilate and wash area after pick up.
Disposal: Dispose waste material in accordance with local, regional, and national regulations.
Handling: Use only in well-ventilated areas; avoid inhalation, ingestion, and contact with skin, eyes, or clothing. Remove contaminated clothing and wash before reuse. Use proper chemical fume hoods when handling freely.
Storage: Store in a tightly sealed container in a dry, cool, and well-ventilated location away from heat and incompatible substances such as strong bases and strong oxidizing agents. Store away from food, beverages, and animal feed. Protect from moisture and direct sunlight; keep container upright to prevent leakage.
Incompatibility: Keep away from strong oxidizing agents and bases that might trigger undesirable reactions.
Exposure Limits: No data available for occupational exposure limits; follow general chemical safety practices.
Engineering Controls: Use chemical fume hood, local exhaust ventilation, and safety showers.
Personal Protective Equipment: Wear protective gloves (nitrile or neoprene recommended), chemical splash goggles, appropriate lab coat or apron, and closed footwear.
Hygiene Practices: Wash hands, face, and any exposed skin thoroughly after handling. Remove contaminated clothing and wash before reuse.
Respiratory Protection: Use NIOSH-approved respirators if airborne exposure is possible or if ventilation is insufficient.

Viscosity: High, typical of ionic liquids
Chemical Stability: Stable under recommended storage and handling; decomposes at high temperatures
Reactivity: Avoid contact with strong oxidizing agents and bases, may react with moisture over time
Conditions to Avoid: Excessive heat, moisture, direct sunlight, incompatible materials
Hazardous Decomposition Products: Toxic fumes including phosphorus oxides, hydride fluorides, nitrous oxides, methylimidazole derivatives
Polymerization: No hazardous polymerization anticipated under normal usage
Routes of Exposure: Inhalation, ingestion, skin and eye contact

Eye Irritation: Causes moderate to severe irritation; potential for corneal injury with high exposure
Skin Sensitization: Cases of contact dermatitis reported when exposed repeatedly or over long durations
Respiratory Effects: Irritation of the respiratory tract may occur if inhaled as mist, dust, or aerosol
Chronic Effects: No definitive long-term studies in humans; related substances demonstrated liver and kidney effects in laboratory animals
Carcinogenicity: No studies linking this chemical to increased risk for cancer according to IARC, NTP, or OSHA
Mutagenicity and Reproductive Toxicity: Studies limited; treat as if potentially harmful until more data becomes available
Ecotoxicity: Toxic to aquatic organisms; evidence exists of long-lasting harmful effects on aquatic ecosystems
Persistence and Degradability: Chemical stability in environment suggests low biodegradation; may remain in soil and water for extended periods
Bioaccumulation Potential: There is some potential for accumulation in aquatic organisms due to low solubility and slow breakdown
Mobility: Low volatility and low water solubility limit mobility in most environmental compartments
Other Information: Do not allow runoff into municipal wastewater systems, surface water, or soil; specialized treatment strongly recommended for laboratory waste
Waste Disposal Methods: Chemical waste must be gathered in labeled, sealed containers. Contact authorized hazardous waste disposal company. Do not dispose with ordinary refuse or via drains.
Disposal of Packaging: Triple rinse containers, dispose drums according to local legislation on hazardous waste
Additional Notes: Adhering to university, industry, and government guidelines is essential. Refrain from uncontrolled disposal practices, such as open burning or unlawful landfilling.
