                 **** SECTION 3 - HAZARDS IDENTIFICATION ****

                              EMERGENCY OVERVIEW
Toxic by inhalation. Danger of cumulative effects. Very toxic to
aquatic organisms; may cause long-term adverse effects in the aquatic

Potential Health Effects
         Exposure to mercury or mercury compounds can cause discoloration on
         the front surface of the lens, which does not interfere with vision.
         Causes eye irritation and possible burns.  Contact with mercury or
         mercury compounds can cause ulceration of the conjunctiva and
         May be absorbed through the skin in harmful amounts. May cause skin
         sensitization, an allergic reaction, which becomes evident upon
         re-exposure to this material. Causes skin irritation and possible
         burns. May cause skin rash (in milder cases), and cold and clammy
         skin with cyanosis or pale color.
         May cause severe and permanent damage to the digestive tract. May
         cause perforation of the digestive tract. May cause effects similar
         to those for inhalation exposure. May cause systemic effects.
         Causes chemical burns to the respiratory tract. Inhalation of fumes
         may cause metal fume fever, which is characterized by flu-like
         symptoms with metallic taste, fever, chills, cough, weakness, chest
         pain, muscle pain and increased white blood cell count. May cause
         central nervous system effects including vertigo, anxiety,
         depression, muscle incoordination, and emotional instability.
         Aspiration may lead to pulmonary edema. May cause systemic effects.
         May cause respiratory sensitization.
         May cause liver and kidney damage. May cause reproductive and fetal
         effects. Effects may be delayed. Chronic exposure to mercury may
         cause permanent central nervous system damage, fatigue, weight loss,
         tremors, personality changes. Chronic ingestion may cause
         accumulation of mercury in body tissues. Prolonged or repeated
         exposure may cause inflammation of the mouth and gums, excessive
         salivation, and loosening of the teeth.

                   **** SECTION 4 - FIRST AID MEASURES ****

         Get medical aid immediately. Do NOT allow victim to rub or keep eyes
         closed. Extensive irrigation with water is required (at least 30
         Get medical aid immediately. Immediately flush skin with plenty of
         soap and water for at least 15 minutes while removing contaminated
         clothing and shoes. Wash clothing before reuse. Destroy contaminated
         Do NOT induce vomiting. If victim is conscious and alert, give 2-4
         cupfuls of milk or water. Never give anything by mouth to an
         unconscious person. Get medical aid immediately. Wash mouth out with
         Get medical aid immediately. Remove from exposure to fresh air
         immediately. 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.
    Notes to 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. Treat symptomatically and supportively. Persons with
         kidney disease, chronic respiratory disease, liver disease, or skin
         disease may be at increased risk from exposure to this substance.
         The use of d-Penicillamine as a chelating agent should be determined
         by qualified medical personnel. The use of Dimercaprol or BAL
         (British Anti-Lewisite) as a chelating agent should be determined by
         qualified medical personnel.

                 **** 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. Water runoff can cause environmental damage. Dike
         and collect water used to fight fire. During a fire, irritating and
         highly toxic gases may be generated by thermal decomposition or
    Extinguishing Media:
         Substance is nonflammable; use agent most appropriate to extinguish
         surrounding fire. Use water spray, dry chemical, carbon dioxide, or
         appropriate foam.

               **** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

    General Information: Use proper personal protective equipment as indicated
                         in Section 8.
         Absorb spill with inert material (e.g. vermiculite, sand or earth),
         then place in suitable container. Avoid runoff into storm sewers and
         ditches which lead to waterways. Clean up spills immediately,
         observing precautions in the Protective Equipment section. Provide

                  **** SECTION 7 - HANDLING and STORAGE ****

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


    Engineering Controls:
         Facilities storing or utilizing this material should be equipped
         with an eyewash facility and a safety shower. Use only under a
         chemical fume hood.
    Personal Protective Equipment

                      Wear appropriate protective eyeglasses or chemical
                      safety goggles as described by OSHA's eye and face
                      protection regulations in 29 CFR 1910.133 or European
                      Standard EN166.
