Hazards: Carbon, nitrogen, sulfur, & sodium oxides. Extinguishing: Use dry chem, CO2, water spray or alcohol resistant foam.  

6. ACCIDENTAL RELEASE: Info: Ventilate area of leak or spill.  Clean‑up personnel may require respiratory protection from dust. Use proper PPE as indicated in Section 8. Spills/Leaks: Sweep up and containerize for reclamation or disposal.  Vacuuming or wet sweeping may be used to avoid dust dispersal.   Disposal: Whatever cannot be saved for reclamation may be delivered to an approved waste disposal facility.  Ensure compliance with local, state and federal regulations.

7. HANDLING & STORAGE: Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid breathing dust. Storage: Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from incompatible substances.

8. EXPOSURE: Facilities storing or utilizing this material should be equipped with an eyewash facility and safety shower.  Use adequate ventilation to keep airborne concentrations low. A local exhaust system which captures the contaminant at its source is recommended to prevent dispersion of the contaminant into the workroom air.
