Inhalation: Move exposed person to fresh air, rinse mouth, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash skin with plenty of water and soap
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, lift eyelids, seek attention if irritation persists
Ingestion: Rinse mouth thoroughly, give water to drink, never give anything by mouth to an unconscious person, seek medical advice if large quantities swallowed
Most Important Symptoms: Mild coughing, respiratory irritation, red or itchy eyes, dry skin
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Media: Do not use direct water jet if powder cloud forms
Special Hazards: Ammonia and phosphorus oxides may emerge under intense heat
Protective Equipment: Firefighters should use self-contained breathing apparatus in confined settings
Burning Characteristics: Product itself does not burn easily, acts mainly as a fire retardant, may char and emit irritants
Personal Precautions: Avoid inhaling dust, wear suitable protective clothing, gloves, goggles, respirator if needed
Environmental Precautions: Prevent large spills from entering drains, watercourses, or soil
Methods for Clean-up: Sweep up spilled material, avoid generating dust, shovel into labeled waste containers, ventilate area, wash spill site after material pickup
Reference to Other Sections: Use recommended personal protective equipment listed below, dispose of waste as described under Disposal Considerations
Safe Handling: Use only in well-ventilated locations, minimize generation of dust, prevent eye and skin contact, do not eat or drink while handling product
Safe Storage: Store tightly closed in original containers, keep in a cool, dry, well-ventilated place, away from strong acids, oxidizers, direct sunlight, food and feed
Shipping Requirements: No special conditions required for coated form
Incompatibilities: Avoid contact with strong acids, strong alkalies may accelerate hydrolysis
TLV/PEL: None established for finished product, treat as nuisance dust: OSHA/PEL – 15 mg/m³ (total), 5 mg/m³ (respirable), ACGIH – 10 mg/m³ (total)
Engineering Controls: Use local exhaust ventilation, enclosed transfer processes are preferable
Personal Protective Equipment: Dust respirator if airborne concentration increases, safety goggles, chemical-resistant gloves (nitrile or PVC), work clothing to prevent skin contact
Hygiene Measures: Wash hands after use, change contaminated clothing, avoid eating and drinking during use
Appearance: White/off-white hydrophobic powder
Odor: Nearly odorless
pH: Slightly acidic to neutral (5.5-7 based on water slurry)
Melting/Decomposition Point: Above 240°C (decomposes, does not melt)
Solubility: Low water solubility (less than 0.5 g/100 ml at 20°C)
Bulk Density: 0.7-0.9 g/cm³
Vapor Pressure: Not applicable
Flash Point: Not flammable
Explosive Properties: Not explosive
Other Properties: Stable under normal storage and handling conditions
Chemical Stability: Stable under recommended conditions
Reactivity: Inert to most common materials
Hazardous Reactions: Avoid strong acids, strong bases and oxidizers, may hydrolyze or decompose at high temperatures
Hazardous Decomposition Products: Ammonia, phosphorus oxides released during intense heating
Polymerization: Will not occur
Acute Toxicity: Low; oral LD50 in rats > 5000 mg/kg
Inhalation: Dust may cause mild, reversible irritation of respiratory tract
Skin Contact: Slightly irritating on extended contact, no known sensitization
Eye Contact: Can produce mild irritation
Chronic Effects: Long-term exposure does not produce cumulative toxicity
Carcinogenicity/Mutagenicity: Not listed as carcinogen or mutagen in IARC, NTP, OSHA, or ACGIH databases
Target Organs: Not known to target specific organs
Ecotoxicity: Not acutely toxic to aquatic organisms; LC50 (96 h, fish) > 100 mg/l
Persistence/Degradability: Slowly hydrolyzes to orthophosphate in environment
Bioaccumulation: Does not bioaccumulate
Mobility: Low mobility in soil due to low solubility
Other Effects: High releases may cause nutrient enrichment of water bodies (eutrophication risk)
Waste Handling: Collect and containerize unused material
Disposal Method: Dispose of according to local, regional, and federal regulations for general chemical waste
Incineration: Only suitable in facilities equipped to handle phosphorus and ammonia emissions
Unused Product: Can often be recycled or used in secondary markets such as non-critical construction materials
Packaging: Decontaminate empty containers before reuse or recycling
UN Number: Not regulated
DOT Classification: Not classified as dangerous for transport
Sea (IMDG): Not classified as marine pollutant or hazardous for shipping
Air (IATA): Not subject to special air transport requirements
