Concentration: >98% pure
Impurities: Trace organics and inorganics below relevant safety thresholds
Ingredient Disclosure: Single-component substance
Additives: No known stabilizers or preservatives present
Inhalation: Move affected person to fresh air if dust inhaled. Rinse mouth and throat with water.
Skin Contact: Rinse with plenty of water; wash using soap; take off contaminated clothing.
Eye Contact: Rinse cautiously with clean water for at least 15 minutes, remove contact lenses if possible.
Ingestion: Rinse mouth thoroughly. Seek medical advice if discomfort persists.
Symptoms: No acute symptoms expected. Prolonged exposure may lead to slight irritation, seek medical help if necessary.
Medical Notes: Supportive care only, no specific antidote available.
Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical powder, carbon dioxide for small fires.
Combustion Hazards: May produce toxic fumes of phosphorous oxides, nitrogen oxides, and sodium compounds on burning.
Protection for Firefighters: Wear self-contained breathing apparatus and full protective gear.
Special Fire Procedures: Avoid inhaling smoke or dust. Cool containers exposed to fire by water mist.
Flammability Limits: Not flammable under typical conditions.
Spill Response: Evacuate area, ventilate, minimize dust creation. Collect using damp cloth or mop.
Personal Protection: Wear gloves, goggles, dust mask or respirator if spill is substantial.
Containment: Avoid runoff into drains, sewers, or water bodies.
Cleanup Method: Sweep or vacuum up (using HEPA filter), transfer to appropriate waste container.
Environmental Precautions: Prevent larger spills from contaminating soil and water resources.
Handling: Avoid dust generation, avoid breathing powders. Wash hands before breaks and after use. Use in a fume hood for weighing.
Storage Conditions: Store tightly closed at 2–8°C in a cool, dry, well-ventilated environment, away from incompatible materials.
Container Materials: Use glass or chemically resistant plastic. Keep container tightly sealed.
Storage Incompatibilities: Strong oxidizers or acids.
Hygiene Practices: Change clothing if substantial dust is present; don’t eat, drink, or smoke in product area.
Exposure Limits: No occupational exposure limits established for this compound.
Engineering Controls: Use local exhaust or containment to minimize airborne dust. General lab ventilation usually sufficient.
Personal Protective Equipment: Nitrile or latex gloves, lab coat, chemical splash goggles. Respiratory protection if dust is generated.
Additional Protective Measures: Eye wash station, safety shower nearby.
Environmental Controls: Prevent formation of airborne powder, contain spills.
