Inhalation: Remove person to fresh air. Keep individual calm and comfortable. Seek medical attention for persistent symptoms, including coughing or wheezing.
Skin Contact: Immediately wash area with mild soap and water. Remove contaminated clothing. If irritation develops or persists, contact medical personnel.
Eye Contact: Rinse gently with lukewarm water for at least 10-15 minutes, keeping eyelids open. Remove contact lenses if feasible. Seek medical advice for pain or vision disturbance.
Ingestion: Rinse mouth thoroughly with water. Do not induce vomiting unless instructed by medical personnel. Contact poison control or a physician for further guidance.
Notes for Physician: Provide symptomatic and supportive treatment. Chemical burns to eyes or skin should receive specialized medical evaluation.
Suitable Extinguishing Media: Dry chemical, CO2, foam, or water fog. Direct water stream may not be effective.
Specific Hazards: Burning liberates toxic fumes of phosphorus oxides, fluorinated compounds, carbon monoxide, and carbon dioxide.
Protective Equipment: Firefighters need self-contained breathing apparatus (SCBA) and full protective gear. Avoid inhalation of combustion products.
Precautions: Evacuate area and contain runoff from fire control measures to prevent environmental contamination.
Explosion Sensitivity: Not known to form explosive mixtures with air but avoid ignition sources due to organic components.
Personal Precautions: Wear gloves, goggles, and lab coat or coveralls. Ensure adequate ventilation. Avoid breathing vapors or dust.
Spill Cleanup: Absorb liquid with inert material (vermiculite, earth, sand), collect mechanically for disposal. Clean area with water and detergent.
Environmental Cautions: Prevent spillage into sewers, waterways, or soil. Notify appropriate authorities if significant quantity is released.
Containment: Use barriers or bunds for larger spills. Place waste in tightly sealed containers for disposal.
Disposal: Refer to disposal considerations below for waste management.
Handling: Use only in well-ventilated areas. Open containers carefully. Avoid breathing vapors or dust. Prevent contact with eyes and skin. Do not eat, drink, or smoke during handling.
Storage Conditions: Store in tightly closed original containers at ambient temperature (15-25°C), away from strong oxidizers and acids. Avoid moisture and direct sunlight. Keep in well-ventilated storage areas, preferably under inert atmosphere for long-term stability.
Special Requirements: Maintain clear labeling on all containers. Rotate stock to ensure minimal shelf time, reducing degradation risk.
Occupational Exposure Limits: No established ACGIH, OSHA, or EU exposure limits for this specific compound. Keep airborne concentrations as low as possible.
Engineering Controls: Use chemical fume hood or local exhaust ventilation. Install eyewash stations and emergency showers in the work area.
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile, neoprene), safety goggles, lab coat, suitable respiratory protection if ventilation is insufficient.
Hygiene Measures: Wash hands thoroughly after handling. Remove contaminated clothing and launder before reuse. Avoid rubbing eyes or face.
Appearance: Clear to pale yellow oily liquid or low-melting solid (may be hygroscopic)
Odor: Faint, ester-like or sweet odor
Odor Threshold: Not determined
pH: Neutral to slightly acidic (diluted aqueous solution)
Melting Point/Range: Typically below 20°C (exact value depends on purity)
Boiling Point: Estimated above 200°C (decomposes before boiling)
Flash Point: >150°C (closed cup, approximate)
Evaporation Rate: Not established
Flammability: Not classified as highly flammable, but can burn
Vapor Pressure: Very low at room temperature
Vapor Density: Heavier than air
Solubility: Miscible with organic solvents; partially soluble in water
Partition coefficient (log Kow): Not determined
Auto-ignition Temperature: Not determined
Decomposition Temperature: >170°C (may release hazardous fumes)
Viscosity: High; varies with temperature
Chemical Stability: Stable under recommended storage and handling conditions. Degrades on exposure to strong acids, bases, or oxidizing agents.
Reactive Conditions: Contact with strong oxidizers may cause violent reactions. Sensitive to heat and moisture over long periods.
Hazardous Decomposition: Generates toxic fumes of phosphine, carbon monoxide, carbon dioxide, fluorinated compounds when combusted.
Polymerization: Will not polymerize under normal usage.
Acute Toxicity: Exact LD50 (oral, dermal, inhalation) data not available; extrapolation from constituent ions and similar phosphonium compounds suggests moderate toxicity on ingestion and skin absorption.
Skin Contact: Causes moderate to severe irritation with prolonged or repeated exposure.
Eye Contact: Provokes intense irritation, possible injury with direct splash.
Inhalation: Inhalation of dust or mist may result in respiratory tract irritation, coughing, and possible pulmonary effects.
Sensitization or Allergic Reaction: Not a known sensitizer but skin exposures can trigger dermatitis in sensitive individuals.
Chronic Exposure: No comprehensive long-term studies conducted. Repeated exposure could lead to liver or kidney effects based on phosphonium chemistry.
Carcinogenicity/Mutagenicity: No data for this compound; not listed by IARC, NTP, or OSHA.
Persistence and Degradability: Trifluoroacetate ion is persistent in aquatic systems and poorly biodegradable. Phosphonium cation may degrade slowly under environmental conditions.
Bioaccumulation Potential: Limited data; trifluoroacetate has potential to bioaccumulate in water systems.
Aquatic Toxicity: Harmful to fish and aquatic invertebrates at moderate concentrations. Chronic exposure may affect algae and microorganisms.
Soil Impact: May have moderate mobility in soils; can leach into groundwater.
Environmental Precautions: Prevent entry to waterways, soil, and drains to limit ecological impact.
Waste Disposal Methods: Collect and deliver waste to hazardous chemical disposal facility or licensed chemical incinerator. Avoid landfill and direct discharge into environment.
Container Handling: Rinse empty containers with compatible solvent and deliver to appropriate waste stream. Do not reuse containers for other purposes.
Regulatory Hazards: Classified as hazardous for disposal due to aquatic toxicity and organofluorine content.
UN Number: Seek guidance on local legal designations since transport regulations for experimental ionic liquids are evolving.
