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

                              EMERGENCY OVERVIEW
Highly flammable. Toxic by inhalation and if swallowed.

Potential Health Effects
    Eye:
         Causes moderate eye irritation.  Vapors may cause eye irritation.
         May cause painful sensitization to light.  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. May be absorbed through the skin in
         harmful amounts.
    Ingestion:
         May cause irritation of the digestive tract. May cause respiratory
         failure. May cause vascular collapse and damage. May cause kidney
         failure.
    Inhalation:
         May cause respiratory tract irritation. May cause visual impairment
         and possible permanent blindness. May cause effects similar to those
         described for ingestion.
    Chronic:
         Prolonged or repeated skin contact may cause dermatitis. Chronic
         inhalation and ingestion may cause effects similar to those of acute
         inhalation and ingestion.

                   **** 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. Do NOT allow victim to rub or keep eyes closed.
         Extensive irrigation with water is required (at least 30 minutes).
    Skin:
         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.
         Get medical aid immediately. Induce vomiting by giving one teaspoon
         of Syrup of Ipecac.
    Inhalation:
         Get medical aid immediately. Remove from exposure to fresh air
         immediately. If not breathing, give artificial respiration. If
         breathing is difficult, give oxygen.
    Notes to Physician:
         Effects may be delayed. Ethanol may inhibit methanol metabolism.

                 **** SECTION 5 - FIRE FIGHTING MEASURES ****

    General Information:
         Containers can build up pressure if exposed to heat and/or fire. As
         in any fire, wear a self-contained breathing apparatus in
         pressure-demand, MSHA/NIOSH (approved or equivalent), and full
         protective gear. Vapors can travel to a source of ignition and flash
         back. During a fire, irritating and highly toxic gases may be
         generated by thermal decomposition or combustion. Flammable Liquid.
         Can release vapors that form explosive mixtures at temperatures
         above the flashpoint.
    Extinguishing Media:
         For small fires, use dry chemical, carbon dioxide, water spray or
         alcohol-resistant foam. Use water spray to cool fire-exposed
         containers. Water may be ineffective.

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

    General Information: Use proper personal protective equipment as indicated
                         in Section 8.
    Spills/Leaks:
         Scoop up with a nonsparking tool, then place into a suitable
         container for disposal. Use water spray to disperse the gas/vapor.
         Remove all sources of ignition. Absorb spill using an absorbent,
         non-combustible material such as earth, sand, or vermiculite. Do not
         use combustible materials such as saw dust.

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

    Handling:
         Wash thoroughly after handling. Remove contaminated clothing and
         wash before reuse. Use with adequate ventilation. Empty containers
         retain product residue, (liquid and/or vapor), and can be dangerous.
         Do not get on skin or in eyes. Do not ingest or inhale. Do not
         pressurize, cut, weld, braze, solder, drill, grind, or expose empty
         containers to heat, sparks or open flames.
    Storage:
         Keep away from sources of ignition. Store in a cool, dry,
         well-ventilated area away from incompatible substances.

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

    Engineering Controls:
         Use adequate general or local exhaust ventilation to keep airborne
         concentrations below the permissible exposure limits.
    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:
                      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.
