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

                              EMERGENCY OVERVIEW
Appearance:  green.
Warning! May cause skin irritation. Harmful if swallowed. May cause
respiratory and digestive tract irritation. May cause severe eye
irritation and possible injury. May cause reproductive and fetal
effects.
Target Organs: None known.

Potential Health Effects
    Eye:
         May cause severe eye irritation.  This product contains a cationic
         dye. Similar dyes have caused permanent injury to the cornea and
         conjunctiva in documented exposure cases with human or rabbit eyes.
    Skin:
         May cause skin irritation.
    Ingestion:
         May cause gastrointestinal irritation with nausea, vomiting and
         diarrhea.
    Inhalation:
         May cause respiratory tract irritation.
    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
         immediately.
    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.
    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
         aid immediately.
    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:
         Treat symptomatically.

                 **** 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. Combustion generates toxic fumes.
    Extinguishing Media:
         For small fires, use water spray, dry chemical, carbon dioxide or
         chemical foam.
    Autoignition Temperature:Not applicable.
    Flash Point:           Not applicable.
    Explosion Limits, lower:Not available.
    Explosion Limits, upper:Not available.
    NFPA Rating: (estimated) Health: 2; Flammability: 0; Reactivity: 0

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

    General Information: Use proper personal protective equipment as indicated
                         in Section 8.
    Spills/Leaks:
         Sweep up, then place into a suitable container for disposal. Avoid
         generating dusty conditions.

                  **** 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. May form flammable dust-air mixtures.
         Avoid contact with skin and eyes. Keep container tightly closed.
         Avoid ingestion and inhalation.
    Storage:
         Do not store in direct sunlight. Store in a cool, dry,
         well-ventilated area away from incompatible substances.

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

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