Product Characteristics

1. Hazard Profile: Not classified as hazardous under 67/548/EEC and 1999/45/EC; physical hazard lies in dust/air mixtures, which may ignite or explode in the presence of ignition sources (slight fire hazard).
2. Stability & Reactivity: Stable at room temperature; avoid heat, flames, sparks, and other ignition sources. Incompatible with alkalises and oxidizers; no hazardous decomposition products specified.
3. First-Aid Highlights:
   • Inhalation: Move to uncontaminated area; administer artificial respiration/oxygen if needed, and seek medical attention immediately.
   • Skin Contact: Wash with soap and water for at least 15 minutes (remove contaminated clothing/shoes); clean/dry clothing before reuse.
   • Eye Contact: Flush with plenty of water for ≥15 minutes, then get medical help.
   • Ingestion: Seek medical attention if a large amount is swallowed.
4. Fire-Fighting Measures: Use dry chemical powder, carbon dioxide, water, or foam; for large fires, use foam or fine water spray (avoid high-pressure water to prevent dust scattering). Firefighters must wear respiratory protective devices and protective clothing.
5. Individual Protection: Wear P1 filter respirators (for inert particles), gloves, safety glasses, lightweight protective clothing, and antistatic shoes. Avoid eating, drinking, or smoking at the workplace; wash hands before breaks and shower after work.
6. Ecological Trait: Biodegradable (degradation period: 28 – 95 days); no other specified adverse ecological effects.
7. Transport Status: Not classified as dangerous goods under IMDG, ADR, RID, ICAO, or IATA regulations.
