Wash clothing before reuse. Ingestion: Never give anything by mouth to an unconscious person. Do Not Induce Vomiting. If conscious and alert, rinse mouth with water. Inhalation: Remove from exposure to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Consult physician. Physician: Treat symptomatically and supportively. 

5. FIRE FIGHTING: wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH, & full PPE. Irritating & toxic gases may be generated by thermal decomp/combustion. Extinguishing: Use water spray, dry chem, carbon dioxide, or alcohol-resistant foam. Hazards: Carbon oxides, nitrogen oxides, sulphur oxides, sodium oxides. 

6. ACCIDENTAL RELEASE: Info: Use proper PPE as indicated in Section 8. Spills/Leaks: Clean up spills immediately, observing precautions in the Protective Equipment Section. Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation. 

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 ingestion and inhalation. Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatibles. 

8. EXPOSURE: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low.
