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

                              EMERGENCY OVERVIEW
Highly flammable. Irritating to eyes. Repeated exposure may cause
skin dryness or cracking. Vapors may cause drowsiness and dizziness.

Potential Health Effects
    Eye:
         Produces irritation, characterized by a burning sensation, redness,
         tearing, inflammation, and possible corneal injury.
    Skin:
         Exposure may cause irritation characterized by redness, dryness, and
         inflammation.
    Ingestion:
         May cause irritation of the digestive tract. May cause central
         nervous system depression, kidney damage, and liver damage. Symptoms
         may include: headache, excitement, fatigue, nausea, vomiting,
         stupor, and coma. May cause liver and kidney damage. May cause
         central nervous system depression, characterized by excitement,
         followed by headache, dizziness, drowsiness, and nausea.  Advanced
         stages may cause collapse, unconsciousness, coma and possible death
         due to respiratory failure.
    Inhalation:
         Inhalation of high concentrations may cause central nervous system
         effects characterized by nausea, headache, dizziness, unconsciousness
         and coma. Causes respiratory tract irritation. May cause liver and
         kidney damage. May cause motor incoordination and speech
         abnormalities.
    Chronic:
         Prolonged or repeated skin contact may cause dermatitis. Chronic
         inhalation may cause effects similar to those of acute inhalation.

                   **** SECTION 4 - FIRST AID MEASURES ****

    Eyes:
         Flush eyes with plenty of water for at least 15 minutes,
         occasionally lifting the upper and lower eyelids. Get medical aid
         immediately.
    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. Wash clothing before reuse.
    Ingestion:
         Do NOT induce vomiting. 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:
         Get medical aid immediately. Remove from exposure to fresh air
         immediately. If not breathing, give artificial respiration. If
         breathing is difficult, give oxygen. Get medical aid. Do NOT use
         mouth-to-mouth resuscitation. If breathing has ceased apply
         artificial respiration using oxygen and a suitable mechanical device
         such as a bag and a mask.
    Notes to Physician:

                 **** 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 may form an explosive mixture with air.
         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. Use water spray to keep fire-exposed
         containers csistant foam. For large fires, use water spray, fog, or
         alcohol-resistant foam. Use water spray to cool fire-exposed
         containers. Water may be ineffective. Do NOT use straight streams of
         water. Cool containers with flooding quantities of water until well
         after fire is out.

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

    General Information: Use proper personal protective equipment as indicated
                         in Section 8.
    Spills/Leaks:
         Absorb spill with inert material (e.g. vermiculite, sand or earth),
         then place in suitable container. Avoid runoff into storm sewers and
         ditches which lead to waterways. Wear appropriate protective clothing
         to minimize contact with skin. Remove all sources of ignition.
         Provide ventilation. A vapor suppressing foam may be used to reduce
         vapors. Water spray may reduce vapor but may not prevent ignition in
         closed spaces. Clean up residual material by washing area with a 2-5%
         solution of soda ash.

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

    Handling:
         Wash thoroughly after handling. Remove contaminated clothing and
         wash before reuse. Use only in a well-ventilated area. Ground and
         bond containers when transferring material. Avoid contact with eyes,
         skin, and clothing. Empty containers retain product residue, (liquid
         and/or vapor), and can be dangerous. Keep container tightly closed.
         Avoid contact with heat, sparks and flame. Avoid ingestion and
         inhalation. Do not pressurize, cut, weld, braze, solder, drill,
         grind, or expose empty containers to heat, sparks or open flames.
    Storage:
         Keep away from heat, sparks, and flame. Keep away from sources of
         ignition. Store in a tightly closed container. Store in a cool, dry,
         well-ventilated area away from incompatible substances.
         Flammables-area.

         **** 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:
                      Wear chemical goggles.
                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.
