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

                              EMERGENCY OVERVIEW
Moisture sensitive.

Potential Health Effects
    Eye:
         May cause eye irritation.
    Skin:
         May cause skin irritation.
    Ingestion:
         May cause irritation of the digestive tract.
    Inhalation:
         May cause respiratory tract irritation.
    Chronic:
         Not available.

                   **** 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.
    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. Get medical aid.
    Inhalation:
         Remove from exposure to fresh air immediately. If not breathing,
         give artificial respiration. If breathing is difficult, give oxygen.
         Get medical aid if cough or other symptoms appear.
    Notes to Physician:

                 **** 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. Dusts at sufficient concentrations can form
         explosive mixtures with air. Dousing metallic fires with water may
         generate hydrogen gas, an extremely dangerous explosion hazard.
    Extinguishing Media:
         Use water spray, dry chemical, carbon dioxide, or chemical foam. Do
         NOT get water inside containers.

               **** 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. Very fine particles can cause a fire or explosion.
         Eliminate all ignition sources. Clean up spills immediately,
         observing precautions in the Protective Equipment section. Avoid
         generating dusty conditions. Provide ventilation. Do not get water
         inside containers.

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

    Handling:
         Minimize dust generation and accumulation. Avoid contact with skin
         and eyes. Avoid ingestion and inhalation. Do not allow contact with
         water. Use only in a chemical fume hood. Keep from contact with moist
         air and steam.
    Storage:
         Store in a tightly closed container. Store in a cool, dry,
         well-ventilated area away from incompatible substances. Store
         protected from moisture.

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

    Engineering Controls:
         Good general ventilation should be sufficient to control airborne
         levels. Facilities storing or utilizing this material should be
         equipped with an eyewash facility and a safety shower.
    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 protective gloves to prevent skin
                      exposure.
            Clothing:
                      Wear a chemical apron. Wear appropriate protective
                      clothing to prevent skin exposure.
         Respirators:
                      A NIOSH/MSHA approved air purifying dust or mist
                      respirator or European Standard EN 149.
