Chemical Name: Ammonium Polyphosphate
CAS Number: 68333-79-9
EC Number: 269-789-9
Concentration: 98-100%
Impurities: May contain traces of orthophosphates and water (typically less than 2%).
Inhalation: Remove person to fresh air, seek medical attention for persistent cough or discomfort; encourage rinsing nose and mouth thoroughly.
Skin Contact: Wash thoroughly with soap and water; seek medical advice if irritation persists; remove contaminated clothing and wash before reuse.
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses, continue washing; seek medical help if irritation continues.
Ingestion: Rinse mouth, do not induce vomiting, seek medical attention if feeling unwell or swallowing significant amounts.
Symptoms: Irritation to eyes, nose, throat; coughing and sneezing possible on inhalation of dust.
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide; large fires can be cooled with plenty of water.
Hazards Arising from Product: Ammonia and phosphorus oxides may evolve at high temperatures; produces irritating fumes in fire; product itself is not flammable.
Protective Equipment: Self-contained breathing apparatus, protective gloves and clothing; avoid inhaling combustion products.
Special Guidance: Avoid runoff into drains; cool containers with water if exposed to fire; control dust-laden air to prevent explosions.
Personal Precautions: Use dust mask, goggles, gloves; avoid contact with eyes and skin; prevent dust from being inhaled; ventilate area.
Environmental Precautions: Prevent entry into waterways, drains, or soil; notify authorities if large quantities spill.
Methods for Cleanup: Sweep up material and place in suitable, labeled containers; avoid generating dust; wash affected area with plenty of water; for larger spills, contain then collect mechanically.
Safe Handling: Avoid creating dust; use in well-ventilated area; keep away from ignition sources; do not eat, drink, or smoke while working with the powder.
Safe Storage: Store in tightly closed containers; keep dry and cool; store away from incompatible materials like strong acids and bases; separate from food and feed products; lock storage to avoid unauthorized use.
Occupational Exposure Limits: Not established specifically for compound; recommended to keep dust below 10 mg/m3 (total inhalable dust, 8-hour TWA).
Engineering Controls: Local exhaust ventilation, general ventilation; enclosed processing; minimize dust generation.
Personal Protective Equipment: Dust mask or respirator (P2 or N95), protective gloves (nitrile or PVC), safety goggles, protective clothing, eye-wash station, accessible water source for washing skin and eyes.
Appearance: White, fine crystalline powder or granules
Odor: Odorless
Molecular Weight: Variable (depends on degree of polymerization)
Solubility in Water: Moderately soluble (around 20-30 g/L at 25°C)
pH (10% solution): 6.5 - 8.0
Melting Point: > 190°C (decomposes)
Density: 1.9 g/cm3
Vapor Pressure: Not volatile
Partition Coefficient: Not applicable
Flash Point: Not flammable
Stability: Stable under normal conditions; decomposes at high temperatures.
Chemical Stability: Stable under recommended conditions of storage; hydrolyzes slowly in humid air, forming ammonia and orthophosphates.
Reactivity: Reacts with strong acids and bases; avoid contact with oxidizing agents; moisture can cause clumping and affect product properties.
Hazardous Decomposition: Produces ammonia, phosphorous oxides, and possibly toxic fumes if heated above 240°C; thermal decomposition may accelerate in presence of certain metals.
Conditions to Avoid: High humidity, excessive heat, exposure to acidic or alkaline substances.
Acute Toxicity: Low oral and dermal toxicity; LD50 (rat, oral) > 3000 mg/kg; not classified as toxic under GHS guidelines.
Skin Corrosion/Irritation: Mild, transient irritation possible with prolonged or repeated contact.
Serious Eye Damage/Irritation: Causes moderate eye irritation, redness and pain if contacted directly.
Respiratory Effects: Dust may irritate mucous membranes, nose, throat, and lungs; symptoms may include coughing and shortness of breath.
Chronic Effects: Not expected to be a sensitizer; no data for carcinogenicity or long-term toxicity in humans.
Aquatic Toxicity: Practically non-toxic to fish and aquatic organisms in typical use concentrations; excessive discharge may promote algal bloom and disturb aquatic ecosystems.
Persistence and Degradability: Degrades to ammonia and phosphate ions, which are naturally occurring but can accumulate to cause eutrophication.
Bioaccumulation Potential: Not expected to bioaccumulate due to rapid breakdown in environment.
Mobility in Soil: High; water solubility promotes movement in wet conditions, risk of leaching to surface and groundwater on large spills.
Other Adverse Effects: Phosphates can alter pH and nutrient balance in soil and water.
Waste Handling: Collect in sealed, labeled containers; keep residues out of sewers and open water; do not combust.
Disposal Methods: Consult local, regional, or national regulations; landfill or licensed waste treatment facility suitable for non-hazardous inorganic chemicals; check local requirements for phosphate waste.
Packaging Disposal: Thoroughly clean and recycle or dispose of containers as non-hazardous waste at approved facilities; avoid reuse for food or water storage.
UN Number: Not regulated as a dangerous good
UN Proper Shipping Name: Not classified
Transport Hazard Class: Not applicable
Packing Group: Not assigned
Transport Labels: None required
Special Precautions: Avoid generating dust during transport; keep containers sealed and protected from moisture; follow general good practice for shipping industrial powders.
Regulations: Listed on major chemical inventories (TSCA, EINECS, DSL, etc.); not classified as hazardous under current GHS, OSHA, or EU CLP criteria.
Restrictions: No specific statutory limitations for handling or usage except general dust and environmental controls for phosphates.
Other Requirements: Use safety data sheets and labels in local language; follow occupational exposure guidelines for dust; check for local limits on phosphate discharges to environment.
