Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Specific Hazards: Dust can form explosive mixtures with air in confined space
Special Hazards: Thermal decomposition generates oxides of carbon
Advice for Firefighters: Wear self-contained breathing apparatus and full protective suit
Combustion Products: Carbon dioxide, carbon monoxide, methane possible in incomplete combustion
Personal Precautions: Avoid creating dust clouds. Use protective gear including mask and eye protection
Spill Response: Sweep or vacuum material for proper disposal. Wash area to remove residues
Environmental Precautions: Prevent large-scale releases from entering drains or watercourses
Methods for Cleanup: Use industrial vacuum or wet methods to avoid dust dispersal. Collect in sealed containers. Rinse residue down drain with plenty of water
Handling: Use with sufficient ventilation to minimize dust generation. Avoid contact with eyes and avoid breathing dust
Hygiene Measures: Wash hands before eating, drinking, or smoking
Fire Prevention: Eliminate sources of ignition when transferring large volumes
Storage Conditions: Keep container tightly closed, dry, and in a cool area. Recommended storage temperature: ambient
Incompatibilities: Strong oxidizing agents
Bulk Storage: Store away from incompatible materials, keep dry to prevent clumping or spoilage
