                   **** 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:
         Immediately 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:
         If victim is conscious and alert, give 2-4 cupfuls of milk or water.
         Never give anything by mouth to an unconscious person. Get medical

                 **** 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. Vapors may
         be heavier than air.  They can spread along the ground and collect
         in low or confined areas.
    Extinguishing Media:
         Use water spray, dry chemical, or carbon dioxide. Use agent most
         appropriate to extinguish fire.
    Autoignition Temperature:Not applicable.
    Flash Point:           Not applicable.
    Explosion Limits, lower:Not available.
    Explosion Limits, upper:Not available.

               **** 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. Minimize dust
         generation and accumulation. Avoid contact with skin and eyes. Avoid
         ingestion and inhalation.
    Storage:
         Store in a cool, dry, well-ventilated area away from incompatible
         substances. Keep containers tightly closed.

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

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