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

                              EMERGENCY OVERVIEW
Contact with water liberates highly flammable gases. Spontaneously
flammable in air.Water-Reactive.

Potential Health Effects
    Eye:
         Dust may cause mechanical irritation.
    Skin:
         Dust may cause mechanical irritation. Particles embedded in the skin
         may cause "chemical gas gangrene" with symptoms of persistent
         lesions, inflammation and gas bubbles under the skin.
    Ingestion:
         May cause irritation of the digestive tract. Low hazard for usual
         industrial handling.
    Inhalation:
         May cause 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.
    Chronic:
         No information found.

                   **** 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.
    Skin:
         Get medical aid. Immediately flush skin with plenty of soap and
         water for at least 15 minutes while removing contaminated clothing
         and shoes.
    Ingestion:
         If victim is conscious and alert, give 2-4 cupfuls of milk or water.
         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.
    Notes to Physician:
    Antidote:
         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. Flammable solid. May react with acids or moisture
         to form explosive hydrogen gas.
    Extinguishing Media:
         Use only graphite powder, soda ash, powdered sodium chloride, or an
         appropriate metal-fire-extinguishing dry powder. Do NOT use water,
         carbon dioxide, or foam.

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

    General Information: Use proper personal protective equipment as indicated
                         in Section 8.
    Spills/Leaks:
         Scoop up with a nonsparking tool, then place into a suitable
         container for disposal. Remove all sources of ignition.

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

    Handling:
         Wash thoroughly after handling. Remove contaminated clothing and
         wash before reuse. Use with adequate ventilation. Ground and bond
         containers when transferring material. Use spark-proof tools and
         explosion proof equipment. Avoid contact with eyes, skin, and
         clothing. Empty containers retain product residue, (liquid and/or
         vapor), and can be dangerous. Avoid ingestion and inhalation. Do not
         pressurize, cut, weld, braze, solder, drill, grind, or expose empty
         containers to heat, sparks or open flames.
    Storage:
         Keep away from sources of ignition. Store in a tightly closed
         container. Store in a cool, dry, well-ventilated area away from
         incompatible substances.

         **** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

    Engineering Controls:
         Use adequate ventilation to keep airborne concentrations low.
    Personal Protective Equipment

                Eyes:
                      Wear chemical goggles and face shield.
                Skin:
                      Wear impervious gloves.
            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.
