General Advice: Show this sheet to the doctor in attendance for reference; treat symptoms as necessary
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide as appropriate for surrounding fire
Special Hazards: Compound does not burn but may release ammonia and phosphorus oxides at high temperatures
Firefighter Protection: Wear self-contained breathing apparatus and full protective gear; avoid inhaling decomposition products
Advice for Firefighters: Cool containers exposed to heat with water spray to prevent rupture
Personal Precautions: Avoid dust formation; use respiratory protection if ventilation inadequate
Spill Cleanup: Sweep or vacuum spilled material into suitable container; prevent spillage from entering drains or watercourses
Environmental Precautions: Avoid direct release to the environment; recover product promptly
Disposal of Cleanup Materials: Place waste in secure chemical waste container; send to authorized disposal facility
Handling: Avoid breathing dust; work in well-ventilated areas, wear gloves and eye protection
Hygiene Measures: Wash hands thoroughly after handling; keep food and drink away from work area
Storage Conditions: Store in tightly closed containers, in cool, dry, well-ventilated location
Incompatibilities: Store away from strong acids and oxidizers; avoid moisture pick-up
Packaging Materials: Use corrosion-resistant containers to prevent deterioration over time
Exposure Limits: No specific occupational exposure limit for ammonium polyphosphate; reference local guidelines for nuisance dusts
Engineering Controls: Local exhaust ventilation or general dilution ventilation to minimize airborne dust
Personal Protective Equipment: Safety glasses with side shields, chemical-resistant gloves, dust respirator for dusty operations
Other Protection: Wear protective clothing to avoid skin contact; eye wash and emergency shower stations accessible in work area
Environmental Exposure: Keep products away from sewers, drains, and water bodies whenever possible
Appearance: White, granular or powder
Odor: Odorless
Odor Threshold: Not applicable
pH: Approx. 6 – 8 (10% aqueous suspension)
Melting/Softening Point: Softening point above 150°C
Boiling Point: Not applicable (decomposes before boiling)
Flash Point: Not flammable
Solubility: Slightly soluble in cold water; more soluble in hot water
Vapor Pressure: Not applicable
Density: 1.6 – 1.9 g/cm3
Decomposition Temperature: Above 240°C
Other: Forms stable, non-deliquescent granules in most storage conditions
Chemical Stability: Stable under normal storage and usage conditions
Possible Reactions: Decomposes on heating, giving off ammonia and phosphorus oxides
Incompatible Materials: Strong acids, bases, strong oxidizing agents
Hazardous Decomposition Products: Ammonia, phosphorus oxides, nitrogen oxides
Conditions to Avoid: Excessive heat, moisture, contact with incompatible substances
Acute Toxicity: Very low acute toxicity if inhaled, ingested, or in contact with skin; estimated LD50 (oral, rat) > 5,000 mg/kg
Skin Corrosion/Irritation: Non-irritating in most cases but dust can dry skin
Eye Damage/Irritation: Dust particles may cause mild irritation
Respiratory or Skin Sensitization: Not a known sensitizer
Long-Term Effects: No evidence for carcinogenicity, mutagenicity, or reproductive toxicity in standard testing
Medical Conditions Aggravated by Exposure: Individuals with pre-existing skin or respiratory disorders may experience increased symptoms with excessive dust exposure
Aquatic Toxicity: Low direct toxicity to aquatic life at typical concentrations, but overloading can stimulate problematic algae growth
Mobility: Moderately mobile in soil if dissolved; most will remain bound to soil particles
Bioaccumulation: Not expected to bioaccumulate in organisms
Degradability: Breaks down slowly to release ammonium and phosphate ions
Environmental Impact: Spills of large amounts can alter water chemistry, leading to accelerated plant growth and depletion of oxygen in waterways
Disposal Methods: Gather leftover material and contaminated packaging and send to licensed waste disposal facility
Product Disposal: Do not dispose of product in sewage systems or open water
