Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Specific Hazards: Does not burn, can release ammonia, phosphorous oxides under intense fire
Special Protective Equipment: Wear self-contained breathing apparatus, protective clothing
Advice for Firefighters: Approach from upwind side, remove containers if safe to do, avoid inhalation of gases generated by thermal decomposition
Personal Precautions: Wear dust mask, eye protection, gloves when dealing with spills
Environmental Precautions: Prevent large spill run-off into waterways, sweep or vacuum up to avoid dust
Methods for Containment: Collect spilled product in labeled containers, use non-sparking tools
Methods for Cleanup: Vacuuming or sweeping recommended, wash spill area with water to remove residues
Handling: Minimize dust formation, use only with local exhaust or ventilation, avoid eating or drinking near the work area
Storage: Keep container tightly closed, store in cool, dry, and ventilated area, separate from foodstuffs and incompatible materials such as strong oxidizers
Packaging: Use bags, drums, or big bags made of compatible materials, avoid damage to keep product dry
Exposure Limits: No established OSHA, ACGIH exposure limits for ammonium polyphosphate
Respiratory Protection: Dust respirator for major handling or spill cleanup
Eye Protection: Safety glasses, goggles
Skin Protection: Chemical-resistant gloves, lab coat or apron when handling bulk product
Engineering Controls: Ensure area ventilation, use dust collection systems during processing or transfer
Appearance: White crystalline powder or granules
Odor: Odorless
Solubility: Slightly soluble in cold water, more soluble at higher temperatures
Melting Point: Above 250°C (decomposes)
pH: Around 5.5–7.5 (10% aqueous suspension)
Molecular Weight: Variable (polymer material)
Bulk Density: Roughly 0.7–1.0 g/cm³
Vapor Pressure: Negligible at room temperature
Other Properties: Stable under normal conditions without a tendency for spontaneous ignition or dangerous reactions
Chemical Stability: Stable during storage and use under recommended conditions
Thermal Decomposition: Releases ammonia gas and phosphorous oxides at high temperatures
Incompatible Materials: Strong oxidizers, strong acids
Hazardous Reactions: Not known to undergo dangerous polymerization or violent reactions under standard conditions
Conditions to Avoid: Excessive heat, exposure to moisture
Acute Toxicity: Low oral and dermal toxicity (LD50 oral rat > 5,000 mg/kg)
Skin Corrosion/Irritation: Non-irritating in animal studies
Eye Damage/Irritation: Mild, reversible irritation possible
Sensitization: Not a skin sensitizer based on available studies
Chronic Effects: Data do not indicate chronic toxicity, mutagenic, or carcinogenic potential at normal exposure levels
Other Information: Extensive testing points toward generally low biological hazard under real-world applications
Aquatic Toxicity: Not regarded as acutely toxic to aquatic life (Daphnia magna EC50 > 100 mg/L, fish LC50 > 100 mg/L)
Persistence and Degradability: Product breaks down to ammonium and phosphate ions over time in natural conditions
Bioaccumulation: Not expected due to water solubility and low octanol-water partition coefficient
Mobility in Soil: High mobility, phosphate binds to soil; ammonium may leach into groundwater in very large spills
Other Ecotoxicological Notes: Excessive quantities in water may foster algal growth, disrupt balance if mismanaged
Waste Treatment Methods: Landfill or incinerate according to local, national regulations
Contaminated Packaging: Rinse thoroughly, recycle or dispose as per attached product labeling and local guidelines
