Inhalation: Move exposed person to fresh air, keep warm and allow to rest; if symptoms continue, seek medical advice; avoid giving mouth-to-mouth to someone with chemical dust on their face
Skin Contact: Remove contaminated clothing; rinse skin with plenty of water for at least 15 minutes; seek medical attention if skin remains irritated
Eye Contact: Immediately rinse eyes with gentle stream of water for at least 15 minutes keeping eyelids open; remove contact lenses; medical attention recommended
Ingestion: Rinse mouth with water; do not induce vomiting; drink plenty of water; obtain medical help if large quantity swallowed or symptoms persist
Most Important Symptoms: Dust exposure may cause coughing, redness; skin or eye contact can cause minor irritation; ingestion may cause mild gastrointestinal upset
Suitable Extinguishing Media: Water spray, dry chemical powder, foam, or CO2 extinguishers
Unsuitable Extinguishing Media: Do not use a direct water jet on product dust, as it may cause spreading
Specific Hazards: Product decomposes under high heat producing ammonia and phosphorus oxides; avoid inhaling fumes from fire
Protective Equipment: Wear self-contained breathing apparatus (SCBA); chemical-protective suit recommended for large fires
Thermal Decomposition: Decomposition releases ammonia, phosphorus pentoxide, nitrogen oxides; ventilate area after fire
Firefighting Instructions: Cool containers exposed to flames with water spray from a safe distance; avoid runoff into sewers and waterways
Personal Precautions: Wear proper protective equipment (gloves, goggles, dust mask); avoid generation of dust; ventilate affected area
Environmental Precautions: Prevent spillage from entering drains or watercourses; in case of entry, notify authorities; minimize dust creation during cleanup
Method for Cleanup: Sweep up using methods that avoid raising dust; place material in suitable, labeled containers for disposal; use damp cloth for final cleaning
Small Spills: Carefully pick up, avoid direct contact; dispose of waste according to local regulations
Large Spills: Contain spill; cover with plastic sheet if needed; avoid washing down drains; coordinate with emergency personnel
Handling: Use only with adequate ventilation; avoid breathing dust; do not eat, drink, or smoke while handling; practice good hygiene; wash thoroughly after working
Storage: Store in tightly sealed containers; keep in cool, dry, well-ventilated area; protect from moisture and direct sunlight; keep away from incompatible substances (strong acids, bases, and oxidizers)
Incompatibility: Keep away from alkalis, strong acids, and oxidizing agents to avoid hazardous reactions
Special Requirements: Store away from food, feed, or water sources; avoid stacking to prevent container collapse
Shelf Life: Stable under recommended storage conditions for several years; product quality may decrease if repeatedly exposed to high humidity
Occupational Exposure Limits: No established permissible exposure level in most jurisdictions; general dust limit for nuisance particulates applies (10 mg/m3 total dust)
Engineering Controls: Use local exhaust ventilation at dust-generating points; keep dust levels below recommended limits
Personal Protective Equipment (PPE): Wear protective gloves, safety goggles, and NIOSH-approved dust mask; use protective clothing in bulk handling
Hygiene Measures: Wash hands before breaks and at end of work; remove contaminated clothing and wash before reuse
Environmental Controls: Install containment to prevent spills, ensure regular cleaning of processing areas to minimize dust accumulation
Appearance: White powder or granules
Odor: Odorless
Molecular Weight: Variable, depending on polymerization degree
pH (10% Solution): 5.5 – 7.5
Melting Point/Range: Begins to decompose above 240°C
Solubility in Water: Low to moderate, increases with temperature; approximately 0.5 – 2 g/100ml at 20°C
Boiling Point: Not applicable (decomposes)
Vapor Pressure: Not applicable (solid, negligible)
Density: 1.9 g/cm³ at 20°C
Flash Point: Not flammable
Explosion Properties: Not explosive
Other Data: Hygroscopic when exposed to high humidity; tends to cake if not stored dry
Chemical Stability: Stable under normal temperatures and recommended conditions
Reactivity: Reacts with strong acids and alkalis, producing heat and flammable ammonia gas
Conditions to Avoid: High temperature, prolonged exposure to moisture, direct sunlight
Hazardous Decomposition Products: Ammonia, phosphorus oxides, nitrogen oxides
Polymerization: Will not occur under normal processing and storage conditions
Incompatible Materials: Strong oxidizers, reducing agents, acidic compounds; contact with these may enhance decomposition
Likely Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Toxicity: Low acute oral and dermal toxicity in animal studies; LD50 (oral, rat) > 5,000 mg/kg
Inhalation: Exposure to dust can cause mild respiratory irritation, coughing, sneezing
Skin Corrosion/Irritation: May cause mild irritation with repeated or prolonged contact
Eye Damage/Irritation: May cause temporary discomfort, redness, or watering
Chronic Effects: No evidence of sensitization, carcinogenicity, or reproductive toxicity in animals or humans
Medical Observations: Prolonged exposure to dust without protection may aggravate asthma or respiratory conditions
Ecotoxicity: Non-toxic to aquatic and terrestrial organisms at typical levels of environmental exposure; LC50 (fish, >100 mg/L)
Mobility: Product is not volatile; slow migration through soil; dissolves in water over time, especially at higher temperatures
Persistence/Degradability: Inorganic material; will gradually hydrolyze to orthophosphate in presence of water
Bioaccumulation Potential: Not expected to bioaccumulate in organisms or food chain
Other Adverse Effects: Large spills may upset nutrient balance in aquatic systems; high phosphate levels contribute to algal growth and eutrophication
