                               EMERGENCY OVERVIEW
Irritating to eyes.The toxicological properties of this material
have not been fully investigated.

Potential Health Effects
     Eye:
          Causes eye irritation.  May cause chemical conjunctivitis.
     Skin:
          May cause skin irritation.
     Ingestion:
          May cause gastrointestinal irritation with nausea, vomiting and
          diarrhea. 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 ****

     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.
     Extinguishing Media:
          In case of fire, use water, dry chemical, chemical foam, or
          alcohol-resistant foam.

                **** 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. Reduce airborne dust and prevent scattering by moistening
          with water. Clean up spills immediately, observing precautions in
          the Protective Equipment section.

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

     Handling:
          Wash thoroughly after handling. Wash hands before eating. Remove
          contaminated clothing and wash before reuse. Use with adequate
          ventilation. Avoid contact with eyes, skin, and clothing. Avoid
          ingestion and inhalation.
     Storage:
          Store in a cool, dry place. Keep container closed when not in use.

          **** 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:
