HMIS Classification: Health hazard  4, Flammability   0,  Physical hazards   0			
NFPA Rating: Health hazard  4, Fire     0, Reactivity hazard   0

Potential Health Effects: Eyes: Contact may cause severe eye irritation and possible eye damage. 
Skin: Harmful if absorbed through the skin. May cause skin discoloration. Causes skin irritation and possible burns.  May cause allergic reaction in certain individuals.  Ingestion: May cause severe gastrointestinal irritation with nausea, vomiting and diarrhea. May cause corrosion and permanent tissue destruction of the esophagus and digestive tract.  Ingestion may cause renal failure.  May cause adverse nervous system effects and possible.  
Inhalation: Harmful if inhaled.  May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema.  May cause effects similar to those described for ingestion.
Chronic: Chronic exposure through any route can produce central nervous system damage.  May cause muscle tremors, irritability, loss of memory and intellect. Can cause skin allergies and accumulate in the body.  Inorganic Mercury substances such as Mercuric sulfate have not been shown to be human teratogens/reproductive effectors, but should be HANDLED WITH CAUTION since related Mercury compounds effect fertility in males and females, and damage the developing fetus.

4. FIRST AID MEASURES: Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper & lower eyelids. Skin: flush skin with soap & plenty of water for at least 15 minutes while removing contaminated clothes and shoes. Ingestion: If victim is conscious and alert, give 2-4 cupfuls water or milk to drink. Do NOT induce vomiting. NEVER give anything by mouth to an unconscious person. Inhalation: Remove from exposure 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 as ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask. 

5. FIRE FIGHTING MEASURES: Info: wear a self-contained 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.  Runoff from fire control or dilution water may cause pollution. Special Hazards: Sulfur oxides, mercury oxides. Extinguishing: Use water spray, dry chemical, carbon dioxide, or alcohol-resistant foam. .

6. ACCIDENTAL RELEASE MEASURES: 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. Sprinkle area with Sulfur or Calcium polysulfide to suppress Mercury. Do not let product enter drains. 

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.  Store protected from light. Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Do NOT store in direct sunlight. Light, Air, and Moisture Sensitive. 

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