Most Important Symptoms: Burning sensation, irritation, nausea, headache, skin redness, eye watering
Notes to Physician: Treat symptomatically; monitor for signs of chemical exposure or respiratory distress; no specific antidote identified
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam; use water spray to cool containers but avoid direct water stream on burning liquid
Unsuitable Extinguishing Media: Avoid high-pressure water jet
Specific Hazards: Thermal decomposition or combustion may produce toxic fumes including phosphorous oxides, carbon monoxide, and other hazardous gases
Protective Equipment for Fire-Fighters: Wear self-contained breathing apparatus, full protective clothing, and gloves
Special Procedures: Evacuate area; prevent runoff of firefighting water to waterways; ventilate enclosed areas after fire
Personal Precautions: Wear chemical-resistant gloves, safety goggles, and protective clothing; use respiratory protection if ventilation is inadequate
Environmental Precautions: Prevent entry to sewers, drains, groundwater, or natural water sources
Containment: Absorb spill with inert materials such as sand or vermiculite; collect solid waste for disposal in labeled containers
Cleanup Methods: Use non-sparking tools; ventilate area; clean residue with suitable detergent; dispose as hazardous waste according to local regulations
Notification: Report significant releases to appropriate emergency response authorities
Safe Handling Advice: Avoid inhalation, skin, and eye contact; use in a well-ventilated space with proper engineering controls; never eat, drink, or smoke when using this material
Technical Measures: Use appropriate local exhaust ventilation; minimize dust generation; handle away from incompatible chemicals
Storage Conditions: Store in tightly sealed containers in a cool, dry, ventilated place away from heat or open flames; protect from moisture and direct sunlight
Incompatible Materials: Avoid storage with strong oxidizers, strong acids, or bases
Specific End Use: Maintain access restrictions to trained professionals
Engineering Controls: Use chemical fume hood, local exhaust ventilation, and containment methods to reduce exposure
Respiratory Protection: Wear NIOSH-approved respirator during operations with inadequate ventilation
Skin Protection: Chemical-resistant gloves (nitrile or neoprene recommended), laboratory coat, closed footwear
Eye/Face Protection: Tight-fitting safety goggles or face shield
Other Controls: Emergency eye wash stations and safety showers in vicinity of use; wash hands after handling
Occupational Exposure Limits: No established OSHA or ACGIH limits for this specific compound; refer to analogs and handle as hazardous
Appearance: Clear to pale yellow liquid or crystalline solid depending on purity and temperature
Odor: Faint, characteristic, possibly irritant
Melting Point: Approximately 40-55°C (literature reports may vary depending on hydration and sample quality)
Boiling Point: Data not fully established due to decomposition
Relative Density: Approximately 1.1-1.3 g/cm3
Solubility: Miscible with polar solvents, moderate solubility in water
pH: Not readily determined for pure material; may influence solvent systems
Vapor Pressure: Low; negligible at room temperature
Partition Coefficient (n-octanol/water): Data not available
Flash Point: Above 120°C (closed cup, estimated)
Decomposition Temperature: >150°C
Viscosity: Moderate to high for ionic liquid, varies with temperature
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Low reactivity at ambient temperatures
Potential Hazardous Reactions: May react with strong oxidizing agents, strong acids, or bases to release toxic gases
Conditions to Avoid: Heating above decomposition temperature; exposure to moisture or air for extended periods
Incompatible Materials: Strong oxidizers, acids, and bases; direct exposure to water forms hydrolysis products
Hazardous Decomposition Products: Phosphorous oxides, carbon monoxide, carbon dioxide, irritating fumes
Likely Routes of Exposure: Skin and eye contact, inhalation of vapors or dust, accidental ingestion
Acute Toxicity: Harmful if swallowed; may cause nausea, vomiting, and gastrointestinal distress; skin contact may produce moderate irritation and redness
Skin Corrosion/Irritation: Potential for irritation or dermatitis with repeated contact
Serious Eye Damage/Irritation: Causes moderate to severe irritation; risk of eye damage after direct contact
Respiratory Sensitization: No specific data, treat as potential irritant
Chronic Effects: Data on long-term exposure are limited; avoid prolonged exposure
Carcinogenicity/Mutagenicity: No data indicating carcinogenic or mutagenic effects available
Other Information: Individuals with pre-existing skin, eye, or respiratory conditions may experience worsening symptoms
Ecotoxicity: Limited empirical data; avoid uncontrolled release due to potential aquatic and soil toxicity typical of organophosphorus compounds
Persistence and Degradability: Ionic liquid structure may resist rapid degradation, persistence in environment should be assumed in absence of data
Bioaccumulative Potential: Not investigated; molecular size may limit bioaccumulation but caution is warranted
Mobility in Soil: Moderate; miscible with water, leaching risk in porous soils
Other Adverse Effects: Toxic to aquatic life by analogy to related phosphonium salts; spill control essential
Waste Treatment Methods: Dispose as hazardous waste according to local, national, and international regulations
Contaminated Packaging: Rinse containers thoroughly; dispose as hazardous waste
Disposal Precautions: Do not discharge to the environment or sewer systems
Special Considerations: Chemical waste should be labeled clearly and stored in sealed containers prior to pickup by licensed waste carriers
