Suitable Extinguishing Media: Water spray, dry chemical or carbon dioxide, use whatever is suitable for surrounding fire
Specific Hazards: Product does not burn, but may decompose on heating to produce toxic fumes such as sodium oxide and phosphorous oxides
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective clothing
Special Precautions: Surrounding areas may become slippery if the product is spilled and reacts with water
Combustion Products: Sodium oxide, phosphorous oxides, irritating and corrosive fumes
Personal Precautions: Avoid contact with skin and eyes, avoid dust formation, ventilate area
Protective Equipment: Gloves, goggles, dust mask or respirator, protective footwear
Spill Response: Sweep up solid product carefully, avoid producing dust, collect in suitable containers for disposal
Environmental Precautions: Prevent large quantities from entering waterways or storm drains, contain spill with barriers
Clean-Up Procedures: Wash spill area with plenty of water after material removal
Handling: Use in well-ventilated areas, avoid breathing dust, avoid contact with eyes or skin, wash hands after use, use tools and containers that are dry and clean
Storage: Store in tightly closed containers, keep in a cool, dry, well-ventilated place, protect from moisture, avoid storage near acids and strong oxidizing agents
Incompatible Materials: Acids, aluminum, magnesium, zinc, strong oxidizers
Storage Container Materials: Use corrosion-resistant containers, avoid metal containers prone to oxidation
Occupational Exposure Limits: No established OSHA PEL or ACGIH TLV for trisodium phosphate; use general dust exposure limit (e.g. total dust 10 mg/m3)
Engineering Controls: General ventilation recommended, local exhaust for dusty processes
Personal Protective Equipment: Safety goggles, chemical-resistant gloves, dust mask in dusty situations, protective clothing
Hygiene Measures: Wash hands thoroughly before eating, drinking, or smoking, keep work area clean
Environmental Controls: Prevent significant release to the environment, use containment and proper waste collection
Appearance: White, granular or crystalline powder
Odor: Odorless
pH: Strong alkaline solution (approx. 11.5 for a 1% solution)
Melting Point: Decomposes at 1583 °C
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Freely soluble in water
Density: Approx. 2.54 g/cm3
Vapor Pressure: Not applicable
Flash Point: Not flammable
Other Properties: Hygroscopic, absorbs moisture from air, forms slippery surface when wet
Chemical Stability: Stable under normal conditions, may absorb moisture and clump over time
Reactivity: Reacts with acids to form sodium salts and phosphoric acid, reacts with ammonium salts to release ammonia
Hazardous Reactions: Mixing with acids produces heat and releases corrosive vapors
Conditions to Avoid: Exposure to moisture or high humidity, contact with acids and incompatible metals (aluminum, magnesium, zinc)
Incompatible Materials: Acids, strong oxidizers, aluminum and similar metals
Decomposition Products: Sodium oxide, phosphorous oxides, irritating fumes on strong heating
Route of Exposure: Inhalation, ingestion, skin, and eye contact
Acute Effects: May cause irritation to gastrointestinal tract if ingested, coughing or respiratory discomfort if inhaled, significant irritation or burns to eyes and skin
Chronic Effects: Prolonged or repeated exposure may result in skin dryness or dermatitis; no long-term chronic toxicity noted for food grade material in regulated use
LD50 Oral (rat): 7400 mg/kg
LD50 Dermal (rabbit): Not well established, likely to be >2000 mg/kg
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, or OSHA
Mutagenicity: No evidence from available data
Aquatic Toxicity: High concentrations may raise pH of water, potentially harming aquatic organisms
Persistence and Degradability: Inorganic, undergoes dissociation and remains in the environment; phosphates may contribute to eutrophication
Mobility: Soluble in water and can migrate through soil, may accumulate in water bodies
Bioaccumulation Potential: Low for sodium and phosphate ions, but phosphate may build up in ecosystems
Other Adverse Effects: Can alter water chemistry, large releases may disrupt ecosystem balance; phosphates commonly regulated to prevent algal blooms
Waste Treatment Methods: Collect and place in suitable, labeled containers for disposal
Disposal of Product: Dispose according to local, regional, or national regulations for inorganic phosphates
Disposal of Packaging: Clean containers before recycling or discarding, avoid release to waterways
