4. FIRST AID MEASURES:
Eye: Flush with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. 
Skin: Get medical aid. Wash clothing before reuse. Flush skin with plenty of soap and water. Destroy contaminated shoes. Get medical attention if irritation develops or persists/ 
Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk or water. NEVER give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting.
Inhalation: Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. 
Notes to Physician: Treat symptomatically and supportively. 

5. FIRE FIGHTING MEASURES:
General Information: As in any fire, wear self-contaminated breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. 
Extinguishing Media: Use extinguishing media most appropriate for the surrounding fire. Use water spray, dry chemical, carbon dioxide, or appropriate foam. 
Flash Point:  Not available.
Autoignition Temperature: Not available.
Explosion Limits, Lower:  Not available.

NFPA Rating:  (estimated) Health:2; Flammability: 0; Instability:0.

6. ACCIDENTAL RELEASE MEASURES:
General Information: Use proper personal protective equipment as indicated in Section 8. 
Spills/Leaks: Clean up spills immediately, observing precautions in the Protective Equipment Section. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Provide ventilation.  

7. HANDLING AND STORAGE: 
Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use adequate ventilation. May form flammable dust-air mixtures. Keep container tightly closed. Do not get in skin or in eyes. Do not ingest or inhale. Wash clothing before reuse. 
Storage: Keep away from heat and flame. Store in a cool, dry place. Keep containers tightly closed. 

8. EXPOSURE CONTROLS / PERSONAL PROTECTION:
Engineering Controls: 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.
