PURITY: 90–100%
Impurities: Occasional trace amounts of sodium salts such as sodium phosphate or sodium sulfate, usually below regulatory threshold for classification as a contaminant
Inhalation: Remove exposed person to fresh air and keep at rest, seek medical attention for persistent irritation, in case of severe exposure provide oxygen by qualified personnel
Skin Contact: Wash affected area immediately with plenty of water, remove contaminated clothing and shoes, launder before reuse, consult a physician if irritation develops
Eye Contact: Rinse opened eye cautiously under gentle running water for at least 15 minutes, lift upper and lower eyelids occasionally, remove contact lenses, seek prompt medical attention
Ingestion: Rinse mouth thoroughly with water, drink water if conscious to dilute, do not induce vomiting, get medical attention if symptoms appear
Suitable Extinguishing Media: Use agents suitable for surrounding fire such as water spray, foam, dry chemical, or carbon dioxide
Unsuitable Extinguishing Media: None known for this material
Specific Hazards: Non-flammable, decomposes above 1000°C releasing toxic fumes of sodium oxide and phosphorus oxides
Protective Equipment: Firefighters should wear full protective gear and self-contained breathing apparatus in areas where product decomposition products may be present
Special Precautions: Move containers from fire area if possible, contain runoff to prevent environmental contamination
Personal Protection: Wear dust mask, chemical resistant gloves, protective goggles, and protective clothing
Environmental Precautions: Prevent entry into waterways, sewers, basements, or confined areas, dike area of spill where possible
Spill Clean Up Methods: Sweep or vacuum up material and place in suitable container for disposal, avoid creating dust, ventilate area, wash spill site with water after material clean-up is complete
Handling: Use local exhaust ventilation to minimize dust generation, avoid contact with eyes, skin, and clothing, do not breathe dust, wash thoroughly after handling, maintain good industrial hygiene practices
Storage: Store in a cool, dry, well-ventilated area away from incompatible substances such as strong acids, label containers, keep containers tightly closed, protect from moisture and water
Packaging Materials: Use original packaging or corrosion-resistant containers
Occupational Exposure Limits: No established OSHA or ACGIH exposure limits for this specific compound, as total dust ACGIH TLV: 10 mg/m³ for nuisance dust may apply
Engineering Controls: Ensure adequate ventilation, preferably through local exhaust or process enclosure, use dust collection systems to reduce airborne concentrations
Personal Protective Equipment: Chemical safety goggles, impervious gloves (nitrile or PVC), dust mask or respirator (NIOSH-approved particulate respirator), protective clothing, wash hands and face before breaks and at end of shifts
