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

                              EMERGENCY OVERVIEW
Highly flammable.The toxicological properties of this material have
not been fully investigated.Moisture sensitive.Air sensitive.

Potential Health Effects
         May cause eye irritation.  May cause lacrimation (tearing), blurred
         vision, and photophobia.  May cause chemical conjunctivitis and
         corneal damage.
         May cause skin irritation and possible burns.
         May cause irritation of the digestive tract. May cause cardiac
         disturbances. The toxicological properties of this substance have not
         been fully investigated. May cause central nervous system effects.
         May cause nausea, vomiting, abdominal pain, and increased
         May cause respiratory tract irritation. The toxicological properties
         of this substance have not been fully investigated. May cause cardiac
         abnormalities. Olfactory fatigue may occur. Can produce delayed
         pulmonary edema. Central nervous system effects, which appear to
         predominate in acute cases are characterized by abnormal fatigue,
         memory difficulties and dizziness.
         No information found.

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

         Immediately flush eyes with plenty of water for at least 15 minutes,
         occasionally lifting the upper and lower eyelids. Get medical aid.
         Get medical aid. Flush skin with plenty of soap and water for at
         least 15 minutes while removing contaminated clothing and shoes. Wash
         clothing before reuse.
         Never give anything by mouth to an unconscious person. Get medical
         aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
         drink 2-4 cupfuls of milk or water.
         Remove from exposure to fresh air immediately. If breathing is
         difficult, give oxygen. Get medical aid. 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
    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. 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. This material in
         sufficient quantity and reduced particle size is capable of creating
         a dust explosion. Reacts with water to form explosive hydrogen gas.
         Flammable solid. May burn rapidly with flare burning effect. May
         re-ignite after fire is extinguished. Runoff from fire control or
         dilution water may cause pollution.
    Extinguishing Media:
         DO NOT USE WATER! Use dry chemical. Do NOT get water inside
         containers. For large fires, use water spray, fog or regular foam.
         Contact professional fire-fighters immediately. For small fires, use
         dry chemical, carbon dioxide, sand, earth, water spray or regular
         foam. Cool containers with flooding quantities of water until well
         after fire is out.

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

    General Information: Use proper personal protective equipment as indicated
                         in Section 8.
         Vacuum or sweep up material and place into a suitable disposal
         container. 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.
         Scoop up with a nonsparking tool, then place into a suitable
         container for disposal. Avoid generating dusty conditions. Remove
         all sources of ignition. Provide ventilation. Place under an inert
         atmosphere. Do not get water inside containers.

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

         Wash thoroughly after handling. Use with adequate ventilation.
         Minimize dust generation and accumulation. Avoid breathing dust,
         vapor, mist, or gas. Avoid contact with eyes, skin, and clothing.
         Empty containers retain product residue, (liquid and/or vapor), and
         can be dangerous. Keep container tightly closed. Avoid contact with
         heat, sparks and flame. Avoid ingestion and inhalation. Handle under
         an inert atmosphere. Store protected from air. Do not allow contact
         with water. Do not pressurize, cut, weld, braze, solder, drill,
         grind, or expose empty containers to heat, sparks or open flames.
         Keep from contact with moist air and steam.
         Keep away from sources of ignition. Keep under a nitrogen blanket.
         Store in a cool, dry, well-ventilated area away from incompatible
         substances. Do not expose to air. Store protected from moisture.


    Engineering Controls:
         Facilities storing or utilizing this material should be equipped
         with an eyewash facility and a safety shower. Use adequate general or
         local explosion-proof ventilation to keep airborne levels to
         acceptable levels.
    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.
                      Wear appropriate protective gloves to prevent skin
                      Wear appropriate protective clothing to prevent skin
                      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.
