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

                              EMERGENCY OVERVIEW
Toxic if swallowed. Causes burns.Corrosive.Toxic.Lachrymator.

Potential Health Effects
    Eye:
         Contact with liquid or vapor causes severe burns and possible
         irreversible eye damage.
    Skin:
         Causes severe skin irritation. Causes skin burns. May cause deep,
         penetrating ulcers of the skin. Contact with the skin may cause
         staining, inflammation, and thickening of the skin.
    Ingestion:
         Harmful if swallowed. May cause severe and permanent damage to the
         digestive tract. Causes gastrointestinal tract burns. Causes throat
         constriction, vomiting, convulsions, and shock.
    Inhalation:
         Effects may be delayed. Causes severe irritation of upper
         respiratory tract with coughing, burns, breathing difficulty, and
         possible coma.
    Chronic:
         Chronic ingestion may cause effects similar to those of acute
         ingestion. Prolonged or repeated exposure may cause corneal damage
         and the development of cataracts and glaucoma.

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

    Eyes:
         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:
         In case of contact, immediately flush skin with plenty of water for
         at least 15 minutes while removing contaminated clothing and shoes.
         Get medical aid immediately. Wash clothing before reuse.
    Ingestion:
         If swallowed, do NOT induce vomiting. Get medical aid immediately.
         If victim is fully conscious, give a cupful of water. Never give
         anything by mouth to an unconscious person.
    Inhalation:
         If inhaled, remove to fresh air. If not breathing, give artificial
         respiration. If breathing is difficult, give oxygen. Get medical aid.
    Notes to Physician:
         After inhalation exposure, observe for 24 to 72 hours as pulmonary
         edema may be delayed.

                 **** 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. Use water
         spray to keep fire-exposed containers cool. Vapors may be heavier
         than air.  They can spread along the ground and collect in low or
         confined areas. Contact with metals may evolve flammable hydrogen
         gas. Containers may explode when heated. Non-combustible, substance
         itself does not burn but may decompose upon heating to produce
         corrosive and/or toxic fumes.
    Extinguishing Media:
         For small fires, use water spray, dry chemical, carbon dioxide or
         chemical foam. Do NOT get water 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. Neutralize spill with a weak acid
         such as vinegar or acetic acid. Avoid runoff into storm sewers and
         ditches which lead to waterways. Clean up spills immediately,
         observing precautions in the Protective Equipment section. Provide
         ventilation.

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

    Handling:
         Wash thoroughly after handling. Remove contaminated clothing and
         wash before reuse. Use only in a well-ventilated area. Do not get in
         eyes, on skin, or on clothing. Keep container tightly closed. Do not
         ingest or inhale. Discard contaminated shoes.
    Storage:
         Do not store in direct sunlight. Store in a tightly closed
         container. Store in a cool, dry, well-ventilated area away from
         incompatible substances. Corrosives 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
         ventilation to keep airborne concentrations low.
    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
