Eye Contact: Rinse immediately under gentle, running water for 10-15 minutes, seeking medical support if irritation continues.
Skin Contact: Remove contaminated clothing, wash area thoroughly using soap and water; medical attention if symptoms appear.
Inhalation: Relocate to fresh air, assist with breathing support if breathing becomes difficult, obtain medical help for persistent symptoms.
Ingestion: Rinse mouth with water, do not induce vomiting, contact local poison control/seek medical evaluation.
Notes for Healthcare Providers: Treatment should target symptoms, keep patient monitored for delayed effects.
Suitable Extinguishing Media: Dry chemical, foam, CO2, water spray.
Unsuitable Media: Straight water jets may spread powder.
Special Hazards: During a fire, decomposition products may include ammonia, phosphoric acid fumes, nitrogen oxides.
Protective Equipment: Full protective gear including self-contained breathing apparatus.
Additional Information: Cool containers with water spray to prevent rupture; prevent contaminated runoff from reaching water sources.
Personal Precautions: Wear dust mask, eye protection, gloves to reduce contact risk.
Environmental Precautions: Block off entry to drains; use barriers to prevent material reaching soil or open water.
Cleanup Procedures: Collect product using shovel or HEPA vacuum—avoid dry sweeping; place in labeled containers for disposal.
Disposal of Spillage: Dispose as chemical waste according to local environmental legislation.
Additional Guidance: Ventilate area during cleanup; wash affected area with water to remove residue.
Handling: Avoid dust formation; wear appropriate PPE. Use with local exhaust ventilation. Avoid touching eyes or face while using product. Do not eat, drink, or smoke in areas where handled. Seek methods that minimize airborne dust.
Storage: Store in cool, dry, well-ventilated spaces. Keep drums or bags tightly sealed when not in use, away from moisture. Separate from incompatible materials such as oxidizers, acids. Protect from direct sunlight, heat sources, and extreme temperature swings. Use pallets or shelving for off-ground storage; keep inventory rotated to minimize degradation risk.
Occupational Exposure Limits: No OSHA PEL or ACGIH TLV assigned; treat as nuisance dust (10 mg/m³ total, 3 mg/m³ respirable fraction recommended guideline).
Engineering Controls: Use with local exhaust ventilation, enclosed process if possible, HEPA filtration for handling powders.
Personal Protective Equipment: NIOSH-certified dust respirator for regular use, safety goggles or face shield, chemical-resistant gloves (nitrile or similar), long-sleeved protective clothing.
Environmental Controls: Regularly monitor air in work areas; avoid uncontrolled releases to environment; install spill containment near storage.
Hygiene: Wash thoroughly after use; remove contaminated clothing prior to eating or leaving work zone.
Appearance: White powder, free-flowing with a faint ammoniacal odor.
Odor: Slightly ammonia-like.
pH (in water): Approximately 5.5-7.5 (10% suspension).
Melting Point: >200°C (decomposes before melting).
Solubility: Low solubility in water; dispersible.
Relative Density: 1.7 - 1.9 g/cm³
Flash Point: Not applicable – non-flammable.

Decomposition Temperature: >220°C
Vapor Pressure: Negligible at room temperature.
Bulk Density: 650-750 kg/m³
Stability: Stable under normal handling and storage.
Possible Hazardous Reactions: Reaction with strong acids produces heat and phosphoric acid. Contact with bases or oxidizers can result in degradation.
Conditions to Avoid: High moisture, direct sunlight, open flames, temperatures above 225°C.
Materials to Avoid: Strong oxidizers, strong acids, reducing agents.
Hazardous Decomposition Products: Ammonia, phosphoric acid fumes, nitrogen oxides during fire or thermal decomposition.
Acute Toxicity: Oral LD50 (rat) >5000 mg/kg (low acute toxicity).
Skin Corrosion/Irritation: Can cause mild, reversible irritation after direct contact.
Serious Eye Damage/Irritation: Causes temporary discomfort, tearing, redness.
Respiratory Sensitization: Prolonged inhalation of dust could trigger coughing, throat discomfort, especially in pre-existing respiratory conditions.
Skin Sensitization: No evidence of allergic sensitization.
Repeated Dose Toxicity: No evidence of serious long-term health effects under occupational exposure conditions.
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No components listed by IARC, NTP, OSHA as carcinogens; no evidence of mutagenic or reproductive effects reported.
Ecotoxicity: Fish LC50 (96h) > 100 mg/l (low acute toxicity to fish), Daphnia EC50 (48h) > 100 mg/l, Algae EC50 (72h) >100 mg/l.
Persistence and Degradability: Inorganic phosphates can persist; biodegradability not applicable.
Bioaccumulative Potential: Not expected to bioaccumulate in aquatic or terrestrial organisms.
Mobility in Soil: Limited mobility, will bind to most soils.
Other Adverse Effects: Large releases may promote eutrophication in water bodies.
Behavior in Environment: Not volatile, unlikely to move far from deposition point.
