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

                              EMERGENCY OVERVIEW
Light sensitive.The toxicological properties of this material have
not been fully investigated.

Potential Health Effects
    Eye:
         May cause eye irritation.
    Skin:
         May cause skin irritation.
    Ingestion:
         May cause irritation of the digestive tract. The toxicological
         properties of this substance have not been fully investigated.
    Inhalation:
         May cause respiratory tract irritation. The toxicological properties
         of this substance have not been fully investigated.
    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. Flush skin with plenty of soap and water for at
         least 15 minutes while removing contaminated clothing and shoes. Wash
         clothing before reuse.
    Ingestion:
         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.
    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:

                 **** 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. Water may
         be ineffective. Material is lighter than water and a fire may be
         spread by the use of water.
    Extinguishing Media:
         This material is lighter than water and insoluble in water. The fire
         could easily be spread by the use of water in an area where the water
         cannot be contained. In case of fire, use carbon dioxide, dry
         chemical powder or appropriate foam.

               **** 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, then place into a suitable container for
         disposal. Avoid generating dusty conditions. Provide ventilation.

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

    Handling:
         Wash thoroughly after handling. Remove contaminated clothing and
         wash before reuse. Use with adequate ventilation. Avoid contact with
         eyes, skin, and clothing. Keep container tightly closed. Avoid
         ingestion and inhalation. Store protected from light.
    Storage:
         Store in a tightly closed container. Store in a cool, dry,
         well-ventilated area away from incompatible substances. Deep freeze
         (below -20&C). Store protected from light.

         **** 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
         ventilation to keep airborne concentrations low.
    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 appropriate protective clothing to prevent skin
                      exposure.
         Respirators:
                      A respiratory protection program that meets OSHA's 29
                      CFR :1910.134 and ANSI Z88.2 requirements or European
                      Standard EN 149 must be followed whenever workplace
                      conditions warrant a respirator's use.
