Eye Contact: Rinse with water for several minutes, remove contact lenses, seek attention if irritation persists
Skin Contact: Wash with plenty of water and soap, remove contaminated clothing, get medical help if irritation develops
Inhalation: Move person to fresh air, offer breathing support if needed, contact medical service for prolonged symptoms
Ingestion: Rinse mouth, drink water, avoid forced vomiting, medical advice recommended for large amounts or persistent symptoms
Notes for Doctor: Treat symptomatically, monitor for allergic reactions or discomfort after exposure
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Unsuitable Extinguishing Media: None known for this substance
Specific Hazards: Non-flammable, does not contribute to combustion, but decomposes at high temperatures forming irritating fumes (phosphorus oxides)
Protective Equipment: Firefighters should use self-contained breathing apparatus and protective clothing
Advice for Firefighters: Avoid inhalation of fumes, cool exposed containers with water spray
Explosion Data: Not explosive, dust may present minor risk if suspended in air with ignition source present
Personal Precautions: Limit dust formation, ventilate the area, use protective gear including gloves, goggles, dust mask or respirator
Environmental Precautions: Avoid release into drains, sewers, or soil, collect spillage promptly
Containment and Clean-Up: Sweep up material gently, avoid creating airborne dust, collect in suitable containers for disposal, wash area with water where possible
Handling: Use in well-ventilated area, avoid breathing dust, minimize contact with skin and eyes, keep containers tightly closed, wash hands after handling
Storage Conditions: Store in dry, cool place, keep away from moisture and incompatible materials (strong acids, bases), ensure containers are clearly labeled
Special Precautions: Prevent moisture accumulation, avoid sources of ignition if large dust clouds may be present, separate from food and animal feeds unless labeled as feed-grade
Occupational Exposure Limits: No specific OSHA or ACGIH limits established; observe general nuisance dust limits 10 mg/m³ (total dust), 5 mg/m³ (respirable fractions)
Engineering Controls: Local exhaust ventilation, process enclosures if high dust expected
Personal Protection: Protective gloves, safety goggles, dust mask or P2 respirator for dusty conditions, protective clothing as needed
Hygiene Measures: Wash hands before eating or drinking, remove contaminated clothing, avoid touching face with dirty gloves
Appearance: White to off-white powder or granules, odorless
pH (10% solution): 6.5 – 7.5
Melting Point: Decomposes at temperatures above 200°C
Solubility: Slightly soluble in water
Density: 2.3 – 2.4 g/cm³
Boiling Point: Not applicable
Vapor Pressure: Negligible
Partition Coefficient: Not applicable
Other Data: Stable under normal physical conditions, no significant odor
Reactivity: Non-reactive under recommended conditions
Chemical Stability: Stable in dry air and at room temperature
Hazardous Reactions: Reacts with strong acids to release phosphoric acid fumes and calcium salts
Conditions to Avoid: Humidity, strong acids or bases, extreme heat
Incompatible Materials: Hydrofluoric acid, strong oxidizers, strong bases
Hazardous Decomposition Products: Phosphorus oxides, calcium oxides under fire conditions
Acute Toxicity: Oral LD50 (rat) > 2000 mg/kg (low toxicity)
Skin Corrosion/Irritation: Mild irritant only with prolonged exposure
Serious Eye Damage/Irritation: Can cause mild irritation, no long-term effects expected
Respiratory Sensitization: Frequent exposure to dust causes respiratory discomfort, chronic inhalation rarely leads to lung effects
Carcinogenicity: Not suspected of causing cancer; not listed by IARC, NTP, OSHA
Other Data: No evidence of reproductive toxicity or mutagenicity from available data
Ecotoxicity: Low aquatic toxicity, high phosphate concentrations may stimulate algal blooms
Persistence and Degradability: Inorganic compound, does not degrade but persists in soil and water
Bioaccumulation: Not expected to bioaccumulate, negligible bioconcentration
Mobility in Soil: Moderately mobile; binds to soil particles over time
Other Ecological Effects: Large-scale releases to water sources can affect nutrient cycles and cause eutrophication
Waste Treatment Methods: Collect and reuse if possible, dispose of in accordance with local regulations
Waste Disposal: Landfill or incineration where permitted, avoid direct disposal to surface water
Contaminated Packaging: Rinse thoroughly before recycling or disposal
Special considerations: Consult local authorities for large-scale disposal, do not dispose into environment
