Viscosity: Viscous at room temperature
Chemical Stability: Stable under normal handling and storage conditions
Reactivity: No hazardous reactivity under recommended storage and handling
Possibility of Hazardous Reactions: Phosphorus-containing esters may hydrolyze slowly with moisture, releasing phenol
Conditions to Avoid: Excessive heat, open flames, exposure to strong acids and oxidizing agents
Incompatible Materials: Strong acids, alkalis, oxidizers
Hazardous Decomposition Products: Phosphorus oxides, phenol, carbon monoxide, carbon dioxide
Routes of Exposure: Skin and eye contact, inhalation of fumes or dust, swallowing
Acute Toxicity: LD50 (oral, rat): >5000 mg/kg; skin irritation may develop with prolonged exposure; eye irritation recognized as significant
Chronic Toxicity: No substantial evidence for carcinogenicity or mutagenicity under typical use; effects on degraded flame retardants must be considered
Symptoms of Exposure: Eye and skin irritation, respiratory discomfort, headache, dizziness at high exposures
Other Health Effects: No evidence of sensitization under normal workplace conditions
Aquatic Toxicity: Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment
Persistence and Degradability: Not readily biodegradable, tends to persist in environment
Bioaccumulative Potential: Potential for bioaccumulation exists due to hydrophobicity
Mobility in Soil: Low mobility in soil, adsorbs strongly to organic matter
Other Adverse Effects: Avoid uncontrolled release to the environment due to chronic effects on aquatic species
Disposal Methods: Dispose of in accordance with local, regional, and national regulations; incineration in a chemical incinerator with afterburner and scrubber recommended
Container Disposal: Triple rinse containers, manage as hazardous waste where indicated
