Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if easy, continue rinsing
Skin Contact: Wash skin with soap and water, remove contaminated clothing, seek medical help if irritation persists
Inhalation: Move to fresh air, seek medical attention in case of difficulty breathing or discomfort
Ingestion: Rinse mouth, do not induce vomiting, seek medical help in case of large ingestion or symptoms
Symptoms: Mild irritation of skin, eyes, or airways; large intake can upset stomach
Suitable Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or foam
Unsuitable Media: No specific restrictions
Hazardous Combustion Products: May release phosphorus oxides or potassium oxides when heated to decomposition
Special Equipment: Wear protective gear, self-contained breathing apparatus
Specific Hazards: Product does not burn, but product dust may slightly aggravate fire fighting conditions by creating clouds
Personal Precautions: Avoid breathing dust, wear face mask or respirator, use gloves
Environmental Precautions: Prevent entry to sewers and natural waterways
Cleanup Methods: Sweep up or vacuum material, place in suitable container for disposal
Spill Response: Use water spray to settle dust, ventilate affected area after cleanup
Handling: Avoid creating dust, handle using standard industrial hygiene practices, wash hands after use
Storage: Store in tightly sealed containers, keep dry and away from combustible materials, avoid moisture entry
Special Requirements: Use only in well-ventilated areas, do not store with strong acids, avoid unnecessary contact
Exposure Limits: No official occupational exposure limits; control dust levels
Engineering Controls: Use local exhaust ventilation, isolated dust-producing processes
Personal Protection: Use safety goggles, gloves, dust mask or respirator for high dust levels
Hygiene Measures: Wash thoroughly after handling, change contaminated clothing, keep food and drink out of work area
Appearance: White crystalline powder or granules
Odor: Odorless
Odor Threshold: Not applicable
pH (1% aqueous): 9–9.5
Melting Point: 340°C (decomposes)
Boiling Point: Not applicable
Solubility: Freely soluble in water
Vapor Pressure: Not relevant
Density: 2.44 g/cm³
Other Properties: Non-flammable, stable under normal conditions, forms alkaline solution in water
Chemical Stability: Stable under most storage and usage conditions
Incompatible Materials: Avoid contact with strong acids, releases heat and phosphoric acid
Dangerous Decomposition Products: Phosphorus oxides, potassium oxides if strongly heated
Other Data: No hazardous polymerization, stable at normal temperatures
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Low oral toxicity (LD50 oral, rat: >5,000 mg/kg)
Chronic Toxicity: No evidence for carcinogenicity, mutagenicity, teratogenic effects from typical exposures
Irritation: Slightly irritating to eyes and airways in powder form
Other Effects: Large doses can disturb body electrolyte balance, low toxicity compared to many chemicals
Ecotoxicity: Not expected toxic to aquatic life at typical discharge levels; very high concentrations may disrupt aquatic ecosystems through nutrient enrichment (eutrophication)
Mobility: Soluble in water, mobile in soil, runoff possible
Persistence: Inorganic salt, low persistence
Bioaccumulation: No bioaccumulation likely
Degradability: Not biodegradable, reacts in environment to form naturally occurring phosphate
Waste Treatment: Dispose of as non-hazardous inorganic chemical waste, follow local, state, and federal regulations
Container Disposal: Rinse thoroughly, recycle or dispose according to local rules
Other Guidelines: Prevent entry of large quantities to natural waters or sewer systems to avoid eutrophication
