Conditions to Avoid: Exposure to high temperature, moisture, direct sunlight
Hazardous Decomposition Products: Hydrogen fluoride, sulfur oxides, phosphorous oxides, fluorinated organics upon decomposition
Acute Toxicity: No acute toxicity studies specific for this compound; low volatility reduces risk from inhalation
Skin Corrosion/Irritation: Causes skin irritation; redness and discomfort likely after prolonged contact
Serious Eye Damage/Irritation: Causes serious eye irritation, pain and watering likely after exposure
Respiratory or Skin Sensitization: Not expected to sensitize, but repeat exposure may cause irritation
Chronic Toxicity: Long-term effects not fully evaluated, but not known to accumulate in mammals
Mutagenicity/Carcinogenicity: No data indicating mutagenic or carcinogenic activity
Other Effects: Ingestion may result in gastrointestinal upset (nausea, vomiting, abdominal pain), no known teratogenic effects
Routes of Exposure: Eye, skin, inhalation, ingestion
Ecotoxicity: Data limited, similar phosphonium salts have shown moderate aquatic toxicity
Persistence and Degradability: Ionic liquids can persist in environment; full degradation profile not established
Bioaccumulation Potential: Potential for bioaccumulation low based on molecular structure, further studies pending
Mobility in Soil: Low solubility in water, likely binds to organic matter in soil
Other Adverse Effects: Precaution recommended to minimize environmental release, avoid discharge to waterways
Aquatic Toxicity: Limited data, recommend containment of spills to protect aquatic life
Disposal Methods: Dispose in accordance with local, regional, and national regulations for chemical waste
Container Disposal: Rinse three times with suitable solvent, puncture and dispose as hazardous waste
