Chemical 				CAS No.			Percent			Hazardous
Mercury (II) chloride		7487-94-7		 98-100% 		      Yes 	

4. FIRST AID: Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical attention immediately.  Skin: Flush skin with plenty of water for at least 15 minutes while removing contaminated clothes and shoes. Get medical attention if irritation develops or persists. Ingestion: POISON material.  If victim is conscious and alert, give 2-4 cup-fulls of water or milk to drink. Do NOT induce vomiting. NEVER give anything by mouth to an unconscious person. Get medical attention if irritation or symptoms appears. Inhalation: Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. Physician: The concentration of mercury in whole blood is a reasonable measure of the body-burden of mercury and thus is used for monitoring purposes.  Person with kidney disease, chronic respiratory disease, liver disease, or skin disease may be at increased risk from exposure to this substance.

5. FIRE FIGHTING: Info: Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH, & full PPE. During a fire, irritating and highly toxic gases may be generated by thermal decomp/combustion.  Substance is noncombustible. Hazards:  hydrogen chloride gas, mercury oxides.  Extinguishing:  Use water spray, dry chemical, carbon dioxide, or alcohol-resistant foam. 

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 PPE section. Avoid generating dusty conditions. Provide ventilation. Do not let product enter drains; entrance into the environment must be avoided. 

7. HANDLING & STORAGE: Handling: Wash thoroughly after handling. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. 
Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Store protected from light. Light and Moisture sensitive.

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