Concentration: > 99% (varies by manufacturer)
Impurities: Usually minor; water, inorganic salts, and trace organic side-products.
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, call a physician if irritation persists.
Skin Contact: Wash off with plenty of water and soap, remove contaminated clothing, obtain medical attention for persistent redness.
Inhalation: Move person to fresh air, assist breathing if required, seek medical help if symptoms continue.
Ingestion: Rinse mouth, never induce vomiting unless instructed by a medical professional, seek medical care if unwell.
Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical powder, or carbon dioxide.
Specific Hazards: During combustion, may release irritating or toxic gases like sulfur oxides and nitrogen oxides.
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective clothing.
Special Procedures: Cool exposed containers with water spray, prevent run-off from entering drains or waterways.
Personal Precautions: Wear protective gear (gloves, goggles, dust mask), avoid dust creation.
Environmental Precautions: Prevent further leakage or spillage if safe to do, stop entry into drains and waterways.
Cleanup Methods: Sweep up, place in suitable and closed containers for disposal, ventilate area, wash spill site after material pickup.
Handling: Handle in a well-ventilated area, reduce dust buildup, always wash hands before eating, drinking, or smoking during use.
Storage: Keep containers tightly closed in a dry, cool, and well-ventilated place; store away from strong oxidizers, acids, or bases.
Incompatible Materials: Oxidizing agents, strong acids, strong bases.
Exposure Limits: No established occupational exposure limits for this compound.
Engineering Controls: Use local exhaust or chemical fume hood to minimize dust.
Personal Protective Equipment: Eye protection (safety glasses), skin protection (gloves, lab coat), respiratory protection (dust mask for powder handling).
Hygiene Measures: Change clothing if contaminated, clean up spills quickly, maintain clean laboratory or work area.
