                              EMERGENCY OVERVIEW
Possible risks of irreversible effects.

Potential Health Effects
    Eye:
         Causes eye irritation.  May cause conjunctivitis.
    Skin:
         Causes skin irritation. Prolonged and/or repeated contact may cause
         irritation and/or dermatitis. May cause skin sensitization, an
         allergic reaction, which becomes evident upon re-exposure to this
         material.

    Ingestion:
         May cause irritation of the digestive tract. May cause liver damage.
    Inhalation:
         Causes respiratory tract irritation. 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 asthma and
         shortness of breath.
May cause headache, coughing, fever, weight
         loss, and pneumoconiosis.

    Chronic:
         Prolonged inhalation may cause respiratory tract inflammation and
         lung damage.

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

Eyes:
         Flush eyes with plenty of water for at least 15 minutes,
         occasionally lifting the upper and lower eyelids. Get medical aid
         immediately.
    Skin:
         Flush skin with plenty of soap and water for at least 15 minutes
         while removing contaminated clothing and shoes. Get medical aid if
         irritation develops or persists. Wash clothing before reuse.
    Ingestion:
         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.
    Inhalation:
         Remove from exposure to fresh air immediately. If not breathing,
         give artificial respiration. If breathing is difficult, give oxygen.
         Get medical aid. Do NOT use mouth-to-mouth resuscitation.
    Notes to Physician:

       **** SECTION 5 - FIRE FIGHTING MEASURES ****

    General Information:
         Evacuate area and fight fire from a safe distance. As in any fire,
         wear a self-contained breathing apparatus in pressure-demand,
         MSHA/NIOSH (approved or equivalent), and full protective gear. May
         burn with invisible flame.
During a fire, irritating and highly

         toxic gases may be generated by thermal decomposition or combustion.
         Dust can be an explosion hazard when exposed to heat or flame.
    Extinguishing Media:
         Use dry sand or earth to smother fire.
Use dry chemical to fight

         fire. Contact professional fire-fighters immediately.


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

General Information: Use proper personal protective equipment as indicated
                         in Section 8.
    Spills/Leaks:
         Clean up spills immediately, observing precautions in the Protective
         Equipment section. Sweep up or absorb material, then place into a
         suitable clean, dry, closed container for disposal. Avoid generating
         dusty conditions. Remove all sources of ignition. Isolate area and
         deny entry. Place under an inert atmosphere. Do not use combustible
         materials such as paper towels to clean up spill.

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

Handling:
         Wash thoroughly after handling. Remove contaminated clothing and
         wash before reuse. Use with adequate ventilation. Minimize dust
         generation and accumulation. Use spark-proof tools and explosion
         proof equipment. Avoid contact with skin and eyes. Keep container
         tightly closed. Avoid contact with heat, sparks and flame. Avoid
         ingestion and inhalation. Handle under an inert atmosphere.
    Storage:
         Keep away from heat, sparks, and flame. Store in a tightly closed
         container.
Keep from contact with oxidizing materials. Store in a
         cool, dry, well-ventilated area away from incompatible substances.

         Keep away from acids. Keep containers tightly closed. Do not expose
         to air. Store under an inert atmosphere.

         **** 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.
    Personal Protective Equipment

                Eyes:
                      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.
                Skin:
                      Wear appropriate gloves to prevent skin exposure.
            Clothing:
                      Wear appropriate protective clothing to prevent skin
                      exposure.
         Respirators:
                      Follow the OSHA respirator regulations found in 29CFR
                      1910.134 or European Standard EN 149. Always use a
                      NIOSH or European Standard EN 149 approved respirator
                      when necessary.
