Impurities: May contain trace levels of heavy metals per manufacturing process controls
Molecular Weight: Approx. 10,000–600,000 (varies by grade)
Inhalation: Move person to fresh air, assist with breathing if symptoms persist, seek medical advice for prolonged discomfort
Skin Contact: Wash with water and soap, remove contaminated clothing, seek attention if irritation occurs
Eye Contact: Rinse with plenty of water for several minutes, remove contact lenses if possible, get medical attention if irritation develops
Ingestion: Rinse mouth, drink water to dilute, seek medical assessment for large ingestions or persistent symptoms
Flammability: Not highly flammable, but powder dust may combust if exposed to an ignition source
Suitable Extinguishing Media: Water spray, foam, dry chemical, or carbon dioxide
Special Hazards: Dust clouds can form explosive mixtures with air; burning releases carbon oxides
