Most Important Symptoms: Redness, pain, possible burns to eyes and skin, respiratory symptoms like cough or shortness of breath, nausea if swallowed
Immediate Medical Attention: Necessary for exposures affecting eyes, mouth, or if inhalation symptoms develop, or for large skin exposures
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam; Water spray for larger fires but avoid water jet directly on burning product
Special Hazards: Product may decompose at high temperatures to produce HF (hydrogen fluoride), phosphorus oxyfluoride, nitrogen oxides, toxic fumes
Firefighter Protection: Self-contained breathing apparatus and protective clothing recommended; Avoid inhaling vapors during combustion
Explosion Data: Not flammable, but thermal decomposition at high heat may create overpressure hazards depending on container
Precautions: Isolate area, prevent runoff entering drains, cool containers exposed to fire
Personal Precautions: Don protective gloves, suitable eye and face protection, avoid breathing vapors or dust, ventilate area immediately
Environmental Precautions: Prevent entry into soil, waterways, drains; Contain leaks using inert absorbent such as vermiculite or sand
Cleanup Methods: Sweep spilled material with care, avoiding dust generation, collect in chemically tight containers for disposal as hazardous waste, rinse affected area with plenty of water under full personal protection
Decontamination: Wash surfaces with dilute alkali and water, then ventilate
Special Advice: Clean-up workers require proper PPE, avoid contact with incompatible materials during cleanup
Handling: Handle with appropriate chemical gloves, goggles, and lab coat in a well-ventilated area, use only non-sparking tools, avoid exposure to moisture
Avoid: Contact with strong bases, acids, oxidizers; Exposure to open flames or heat
Hygiene Practices: Wash hands thoroughly after handling, keep working areas clean, avoid eating, drinking, or smoking while working
Storage: Keep container tightly closed in a cool, dry, well-ventilated place, store in original packaging, protect from moisture and humidity
Incompatibles: Water, strong oxidizing agents, alkali metals
Control Parameters: Occupational exposure limit values not established; Minimize exposure by engineering controls
Engineering Controls: Work under chemical fume hood, use local exhaust ventilation, keep containers tightly sealed
Personal Protective Equipment: Chemically resistant gloves (nitrile recommended), safety goggles, face shield in case of splash risk

Density: About 1.29 g/cm³
pH: Not measurable, reacts with water
Vapor Pressure: Negligible at ambient conditions
Partition Coefficient (n-octanol/water): Not determined
Decomposition Temperature: Greater than 150 °C, releasing hazardous decomposition products
Other Properties: Hygroscopic, may hydrolyze slowly on exposure to air
Chemical Stability: Stable in sealed containers under dry, ambient conditions, sensitive to moisture
Reactivity: Reacts with water to generate acids such as HF
Possibility of Hazardous Reactions: Contact with strong oxidizers, acids, or bases may cause exothermic reactions
Conditions to Avoid: Moist air, high temperatures, open flames
Incompatible Materials: Water, strong oxidizers, bases, alkali metals
Hazardous Decomposition Products: Hydrofluoric acid, phosphorus oxides, nitrogen oxides, imidazole derivatives
Likely Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: Oral LD50 (rat) approximately 500–2000 mg/kg; can cause moderate to severe irritation on skin or eyes
Chronic Toxicity: No detailed long-term studies, but chronic exposure expected to cause skin and eye sensitization
Symptoms of Exposure: Eye and skin irritation, gastrointestinal distress, respiratory irritation
Carcinogenicity: No classification by IARC, OSHA or NTP
Mutagenicity, Reproductive Toxicity: Data limited; precaution warranted during long-term use
Other Information: Rapid medical intervention helps reduce the impact of eye and respiratory exposures
Ecotoxicity: Not well studied, but likely toxic to aquatic and soil organisms due to hexafluorophosphate ion and low biodegradability
Persistence and Degradability: Ionic liquids generally exhibit slow breakdown; product likely resistant to environmental degradation
Bioaccumulation Potential: Limited data available, precaution advised to prevent environmental release
Mobility in Soil: Expected to leach through soil slowly unless immobilized by adsorption
Other Adverse Effects: May contribute to long-term environmental persistence if discharged in significant quantities; avoid release to the environment
Waste Treatment Methods: Dispose according to local, regional, and national hazardous waste regulations, avoid landfill disposal whenever possible
Incineration: Approved chemical incinerator with afterburner and scrubber preferred for complete destruction
