5. FIRE FIGHTING: Info: Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH & full PPE. Dusts at sufficient concentrations can form explosive mixtures with air. Combustion generates toxic fumes. Hazards: Carbon, nitrogen, Sulphur & sodium oxides. Extinguishing: Use water spray, dry chem, carbon dioxide or alcohol-resistant foam. Flash Pt: N/A Auto-ignition Temp: N/A. Explosion Limits: N/A. 

6. ACCIDENTAL RELEASE: Info: Use proper PPE as indicated in Section 8. Spills/Leaks: Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions.  

7. HANDLING & STORAGE: Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation & accumulation. Avoid contact with skin & eyes. Keep container tightly closed. Avoid ingestion and inhalation. Storage: Store in a cool, dry, well-ventilated area away from incompatibles. 

8. EXPOSURE: Good general ventilation should be sufficient to control airborne levels.  Local exhaust may be necessary to control concentrations to acceptable levels.
