Recommended Restrictions: Industrial and commercial use only
Hazard Classification: Not classified as hazardous under GHS criteria
Main Health Risks: Eye irritation, mild skin irritation, discomfort if ingested
Specific Hazards: Dust can cause mild respiratory irritation; large spills in workplaces raise slip hazard concerns
Label Elements: No special pictogram required; precautionary statements about dust and exposure
Chronic Risks: Long-term exposure unlikely to cause chronic illness, but repeated contact with dust should be avoided
Other Symptoms: Redness or itching of skin, mild cough or throat irritation following dust inhalation
Main Ingredient: Ammonium Polyphosphate (APP), CAS No. 68333-79-9, Concentration: >95%
Impurities: Small traces of orthophosphates, water, ammonium phosphate monomers
Additives: None typically present unless specified by supplier
Hazardous Components: No components classified as hazardous above threshold levels
Inhalation: Move to fresh air, stay at rest, seek medical attention if symptoms continue
Eye Contact: Rinse with plenty of water for at least ten minutes, avoid rubbing eyes, get medical help for ongoing symptoms
Skin Contact: Wash with soap and warm water, remove contaminated clothing or shoes
Ingestion: Rinse mouth, drink water, seek medical help if a large amount is swallowed
Symptoms to Watch: Persisting irritation, difficulty breathing, allergic-type reactions
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, or foam
Specific Hazards: Product itself is not flammable, but packaging burns; thermal decomposition releases ammonia and oxides of phosphorus
Protective Equipment: Firefighters wear standard gear, use self-contained breathing apparatus for large fires
Special Procedures: Approach fire from upwind, prevent runoff into water bodies
Decomposition Products: Ammonia gas, phosphorus oxides, possible acidic vapors
Personal Protection: Wear dust mask, goggles, gloves
Environmental Precautions: Prevent large quantities entering drains or surface water
Spill Cleanup: Sweep up spills, collect in suitable container, avoid creating dust
Disposal of Spilled Material: Dispose of according to local regulations, use clean tools
Large Spill Measures: Cordone off area, ventilate if indoors, call emergency response if needed
Safe Handling: Manage with care to avoid dust generation, keep container closed when not in use
Personal Hygiene: Wash hands and face thoroughly after handling, keep food and drinks away from work area
Storage Conditions: Store in dry, cool, well-ventilated area, keep away from incompatible materials like strong acids
Packaging Materials: Use moisture-resistant containers, keep original labeling intact
Incompatibilities: Strong oxidizers, reducing agents, strong acids
Exposure Limits: No specific workplace exposure limit set for ammonium polyphosphate
Engineering Controls: Local exhaust ventilation recommended, especially in high-dust areas
Personal Protection: Respiratory protection like a dust mask, chemical goggles for eyes, gloves for hand protection
Other Protection: Use long sleeves and closed shoes for extended handling
Hygienic Measures: Remove contaminated clothing, avoid touching eyes and mouth during use
Appearance: White granular or powder form
Odor: Odorless
Solubility: Slowly soluble in water (varies by polymer chain length), forms clear solution
pH Value: Typically mildly acidic to neutral (pH 5–8 in 1% solution)
Melting Point: Decomposes above 240°C, does not melt cleanly
Boiling Point: Not applicable—decomposes on heating
Density: About 1.8 g/cm3
Vapor Pressure: Not volatile
Flammability: Not flammable—used as flame retardant
Other Data: Stable under normal conditions, forms dust in dry air
Chemical Stability: Stable under recommended storage and use conditions
Reactivity: Not reactive under normal environmental or storage conditions
Hazardous Reactions: Contact with strong acids can release ammonia fumes
Incompatible materials: Strong acids, bases, oxidizers
Decomposition Products: Ammonia, phosphoric acid, oxides of phosphorus at high temperatures
Acute Toxicity: Low toxicity if swallowed or inhaled; LD50 (oral, rat) > 2000 mg/kg
Skin Corrosion/Irritation: May cause mild irritation after prolonged contact
Eye Damage/Irritation: May cause redness or discomfort
Sensitization: No reports of sensitization or allergic response
Chronic Effects: No evidence of chronic health issues in exposed workers based on current data
Carcinogenicity: Not listed by IARC, NTP, or OSHA
Other Data: No known reproductive or mutagenic effects
Aquatic Toxicity: Low toxicity to aquatic life in typical application concentrations
Persistence and Degradability: Breaks down in soil to release plant nutrients, does not bioaccumulate
Bioaccumulation Potential: Unlikely due to high water solubility and mobility in soil
Mobility in Soil: Moves freely through soil; risk of nutrient runoff to waterways if mismanaged
Other Environmental Effects: Large spills may cause eutrophication in water systems; small-scale, lawful use for fertilizer considered safe
Waste Disposal Methods: Dispose as non-hazardous waste according to local, regional, national laws
Packaging Disposal: Triple-rinse, dispose or recycle in line with local requirements
Special Precautions: Avoid direct release of large amounts to sewers or water bodies
Preferred Methods: Landfill or incineration at authorized facilities if recycling not an option
UN Number: Not regulated under UN transport regulations
Transport Hazard Class: Not classified as hazardous for transport
Packing Group: No packing group required
Environmental Risks: No special risk during proper transport conditions
Special Transport Precautions: Keep dry, prevent spillage during loading or unloading, use sealed containers to avoid dust release
Global Chemical Inventory Listings: Listed on international inventories including TSCA (US), EINECS (EU), DSL (Canada)
OSHA Hazard Communication: Product complies with OSHA’s Hazard Communication Standard
SARA Title III: Not listed as a hazardous substance under SARA sections 302, 304, 311, or 312
Labeling Requirements: No mandatory hazard symbol on packaging; recommend standard workplace precautionary labeling
Chemical Safety Assessment: Not required for this product category under REACH (EU) due to low hazard status
Other Local Laws: Check with local environmental or occupational health authorities for limits and special restrictions
