Section 3 - Hazards Identification

EMERGENCY OVERVIEW

Appearance: green crystals.
Danger! May be fatal if inhaled, absorbed through the skin or swallowed. Danger of cumulative effects. The toxicological properties of this material have not been fully investigated.
Target Organs: Nervous system.


Potential Health Effects
Eye: May cause eye irritation. May cause conjunctivitis.
Skin: May be fatal if absorbed through the skin. May cause irritation and dermatitis.
Ingestion: May be fatal if swallowed. May cause central nervous system depression. May cause excessive salivation and loosening of the teeth. May cause nausea, vomiting, and diarrhea, possibly with blood.
Inhalation: May be fatal if inhaled. May produce general weakness, vomiting, diarrhea, chest pains, coughing, shortness of breath, and cardiac insufficiency. Causes irritation of the mucous membrane and upper respiratory tract.
Chronic: There is a danger of cumulative effects. Chronic exposure to mercury compounds may produce immunologic glomerular disease.

Section 4 - First Aid Measures


Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid imme diately.
Skin: Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Discard contaminated clothing in a manner which limits further exposure.
Ingestion: Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation: Get medical aid immediately. Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Do not use mouth-to-mouth resuscitation if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures


General Information: As in any fire, 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.
Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical foam.

Section 6 - Accidental Release Measures


General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Vacuum or sweep up material and place into a suitable disposal container. Do not flush into a sewer. Avoid generating dusty conditions. Provide ventilation.

Section 7 - Handling and Storage


Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well-ventilated area. Minimize dust generation and accumulation. Do not breathe dust, mist, or vapor. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale. Use only in a chemical fume hood. Discard contaminated shoes.
Storage: Store in a tightly closed container. Poison room locked. Store in a cool, dry area away from incompatible substances.

Section 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 general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
