Chemical Name: Triphenyl Phosphate
Common Uses: Plasticizer, flame retardant in various plastics and rubbers, found in hydraulic fluids, coatings, and other industrial materials
Appearance: White crystalline solid, mild aromatic odor
CAS Number: 115-86-6
GHS Classification: Eye and skin irritant, potential endocrine disruptor, harmful if ingested
Signal Word: Warning
Major Hazards: Irritation to eyes and skin, environmental risk for aquatic life, long-term exposure possibly affecting reproductive system
Hazard Symbols: Exclamation mark
Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Chemical Formula: C18H15O4P
Purity: Typically greater than 99% for industrial use
Impurities: Traces of related phosphate compounds or residual solvents from manufacturing
Inhalation: Remove to fresh air, seek medical attention for persistent symptoms
Skin Contact: Wash with mild soap and plenty of water, remove contaminated clothing
Eye Contact: Rinse eyes gently with water for several minutes, get medical help if irritation develops
Ingestion: Rinse mouth with water, do not induce vomiting, consult a healthcare professional promptly
Suitable Extinguishers: Water spray, dry chemical, foam, or carbon dioxide
Special Hazards: Burning may generate toxic fumes containing oxides of phosphorus, carbon monoxide, carbon dioxide
Precautions for Firefighters: Use self-contained breathing apparatus and protective gear, limit exposure to smoke and vapors, remove containers from fire area if safe to do so
Personal Precautions: Wear gloves, goggles, and protective clothing to avoid skin contact
Spill Response: Scoop up solids, avoid raising dust, ventilate area thoroughly, dispose of contaminated materials properly
Environmental Protection: Prevent entry into drains and waterways, report large spills to appropriate agency
Handling: Use in a well-ventilated space, avoid direct skin contact, avoid breathing dust or vapors
Storage: Keep containers sealed tightly, store away from heat or open flames, protect from moisture, store away from strong acids and oxidizers
Engineering Controls: Local exhaust ventilation or general room ventilation to keep dust below regulatory exposure limits
PPE: Chemical-resistant gloves, safety goggles, lab coats or aprons, NIOSH-approved respirator if dust generation is unavoidable
Environmental Controls: Implement spill containment, collect and treat wastewater, monitor effluent before release
Appearance: Crystalline white powder
Odor: Mild, aromatic
Melting Point: Around 48-51 °C
Boiling Point: Decomposes above 150 °C
Solubility: Insoluble in water, soluble in common organic solvents
Chemical Stability: Stable under normal conditions
Reactivity: Reacts with strong oxidizing agents, strong acids
Hazardous Decomposition: Phosphorus oxides, carbon monoxide, and carbon dioxide generated during high heat or combustion
Conditions to Avoid: Excessive heat, open flames, exposure to incompatibles
Acute Effects: Causes eye and skin irritation, mild respiratory discomfort possible if inhaled
Chronic Effects: Prolonged or repeated exposure may impact liver or kidneys, reproductive toxicity observed in some animal studies
Possible Symptoms: Headache, nausea, dizziness after large exposure; no confirmed evidence for human carcinogenicity at typical exposure levels in industrial settings
Aquatic Toxicity: Harmful to aquatic organisms at higher concentrations, persistence in sediment presents a risk of bioaccumulation
Biodegradability: Breaks down slowly in the environment
Mobility in Soil: Tends to stay bound to soil and organic matter, less likely to leach into groundwater, but improper disposal can elevate local concentrations
Waste Management: Incineration preferred for complete destruction, consult local regulations for hazardous waste classification
Container Disposal: Decontaminate containers before recycling or disposal, never reuse for other chemicals
Additional Notes: Avoid dumping in sewers or waterways, always follow regional environmental protection guidelines
UN Number: Not typically classified as hazardous for most modes of transport
Transportation Precautions: Secure packaging to prevent spills during transit, avoid shipment with incompatible substances, mark containers clearly
Storage in Transit: Protect from heat and moisture
Workplace Exposure Limits: Refer to national health and safety authority standards, as limits might differ between countries
Regulatory Listings: Included on many regional lists for hazardous substances, especially in the context of environmental protection and chemical safety standards
Labeling Requirements: Provide hazard pictograms, clear risk phrases and precautionary statements as defined by GHS and local law
