4. FIRST AID: Eyes:  Flush eyes with plenty of water as a precaution.  Skin: flush skin with plenty of soap & water. Ingestion: If victim is conscious and alert, give water to rinse mouth. . Do NOT induce vomiting. NEVER give anything by mouth to an unconscious person. Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.    Physician: Treat symptomatically and supportively.

5. FIRE FIGHTING: Info: wear a self-contained breathing apparatus if necessary. Non-combustible, substance itself does not burn but may decompose upon heating to produce irritating, corrosive and/or toxic fumes. Extinguishing: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Hazards: Calcium Oxide

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

7. HANDLING & STORAGE:  Handling: Wash thoroughly after handling. 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 incompatible substances. Keep away from strong acids.

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