Chemical Identity: Ammonium Polyphosphate
CAS Number: 68333-79-9
Concentration: 98-100%
Impurities: Less than 2% orthophosphates, trace ammonium sulfate
Additives: None known; uses pure grade for textile treatment
Inhalation: Move to fresh air; Seek medical attention if symptoms such as coughing or shortness of breath persist
Skin Contact: Remove contaminated clothing; Wash skin thoroughly with soap and water for at least 15 minutes
Eye Contact: Rinse cautiously with water for several minutes; Remove contacts if present and continue rinsing
Ingestion: Rinse mouth but do not induce vomiting; Consult physician if discomfort occurs; Small accidental ingestion not expected to pose severe risk
Suitable Extinguishing Media: Water spray, foam, dry chemical, or carbon dioxide
Fire Hazards: Not combustible, decomposition may release ammonia and phosphorous oxides
Protective Equipment: Firefighters should wear self-contained breathing apparatus, full body protective gear
Special Procedures: Cool containers with water spray to prevent possible pressure build up; Avoid inhaling fumes from decomposition
Personal Precautions: Wear gloves and goggles; Avoid dust generation; Ventilate affected area
Spill Procedure: Sweep up and shovel material; Minimize dust; Use vacuum or wet methods where possible
Containment: Prevent large spills from reaching drains or waterways
Disposal: Collect for proper disposal following local regulations
Handling: Use only in well-ventilated areas; A mask or respirator limits dust exposure during mixing or loading
Storage: Keep in sealed, labeled containers, stored in cool, dry areas away from acids and oxidizers; Store off the ground and protected from moisture
Other Precautions: Wash thoroughly after handling; No eating or smoking in storage or handling areas; Keep away from children
Exposure Limits: No specific OSHA or ACGIH limits for ammonium polyphosphate; Use general nuisance dust limit (10 mg/m³ total)
Engineering Controls: Local exhaust ventilation during bulk handling
Personal Protection: Chemical-resistant gloves, safety glasses with side shields, and NIOSH-approved dust mask for dusty operations; Eyewash stations recommended nearby; Wear long sleeves and pants when handling large quantities
Appearance: White granular powder
Odor: Nearly odorless
Solubility: Slightly soluble in water, forming suspension
pH (10% solution): Between 5.0 and 7.0
Melting/Decomposition Point: Above 240°C, decomposition to ammonia and phosphates
Specific Gravity: 1.9-2.1 g/cm³
Vapor Pressure: Negligible at ambient temperatures
Evaporation Rate: Not applicable
Flammability: Not flammable
Explosion Limits: Not explosive
Chemical Stability: Remains stable under recommended storage conditions
Reactivity: Reacts with strong acids to release ammonia gas; Contact with oxidizers may cause hazardous situations
Hazardous Decomposition: Ammonia and oxides of phosphorus released at elevated temperatures
Polymerization: Product will not polymerize
Likely Routes of Exposure: Inhalation, skin or eye contact, ingestion
Acute Toxicity: LD50 (oral, rat) > 2000 mg/kg (low toxicity)
Irritation: Mild eye and skin irritant; some reports of nasal irritation from dust
Chronic Effects: No evidence of sensitization or reproductive toxicity
Carcinogenicity: Not listed as carcinogen by IARC, NTP, OSHA
Medical Conditions Aggravated: Persons with pre-existing respiratory issues may experience symptoms from dust exposure
Aquatic Toxicity: Not toxic to fish or aquatic organisms at environmental concentrations expected from normal use
Persistence and Degradability: Slowly biodegradable; Phosphate ions may promote algae growth in waterways
Bioaccumulation: No evidence of bioaccumulation in aquatic species
Soil Mobility: Tends to bind in soil matrices, minimal movement expected
Disposal Methods: Treat as non-hazardous industrial solid waste; Dispose in accordance with local, state, and federal regulations
Contaminated Packaging: Rinse containers and recycle if possible; Otherwise, dispose with authorized provider
Special Precautions: Do not discharge large amounts to water systems; Product can fertilize unwanted algae growth
