Mercurous Nitrate 2 HY                                              7782-86-7      	 90-100%                   Yes 	

4. FIRST AID: Inhalation: Remove to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.  Do NOT use mouth-to-mouth resuscitation.  If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.   Ingestion: Do NOT induce vomiting.  If conscious and alert, rinse mouth and drink 2-4 capfuls of milk or water. Never give anything by mouth to an unconscious person. Skin: Immediately flush skin with soap and plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Eyes:  Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. 

5. FIRE FIGHTING: Info: Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH & full PPE.  Combustion generates toxic fumes.  Strong oxidizer. Contact with other may cause fire.  Runoff may cause pollution. Haz: Nitrogen & Mercury oxides. Extinguishing:  use water, dry chemical, chemical foam, or alcohol-resistant foam.

 6. ACCIDENTAL RELEASE: Info:  Use proper PPE as indicated in Section 8. Spills/Leaks:  Clean up spills immediately, observing precautions in the PPE section.  Sweep up, then place into a suitable container for disposal.  Avoid generating dusty conditions.  Provide ventilation.  Sprinkle area with Sulfur or Calcium polysulfide to suppress Mercury.  Do not let material enter the environment/drains.

7. HANDLING & STORAGE: Handling:  Wash thoroughly after handling.  Minimize dust generation & accumulation.  Do not get in eyes, on skin, or on clothing.  Keep container tightly closed.  Do not ingest or inhale.  Store protected from light.  Keep from contact with clothing & other combustibles. Storage:  Do not store near combustibles.  Do not store in direct sunlight.  Store in a tightly closed container.  Store in a cool, dry well-ventilated area, away from incompatibles.

8. EXPOSURE CONTROLS / PPE:  Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.  Use adequate ventilation to keep airborne levels to acceptable levels.
