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

                              EMERGENCY OVERVIEW
Toxic by inhalation. Causes severe burns.Corrosive.

Potential Health Effects
    Eye:
         May cause irreversible eye injury.  Vapor or mist may cause
         irritation and severe burns.  Contact with liquid is corrosive to the
         eyes and causes severe burns.  May cause painful sensitization to
         light.
    Skin:
         May be absorbed through the skin in harmful amounts. May cause skin
         sensitization, an allergic reaction, which becomes evident upon
         re-exposure to this material. Contact with liquid is corrosive and
         causes severe burns and ulceration.
    Ingestion:
         May cause circulatory system failure. Causes severe digestive tract
         burns with abdominal pain, vomiting, and possible death. May cause
         corrosion and permanent tissue destruction of the esophagus and
         digestive tract. May be harmful if swallowed.
    Inhalation:
         May cause severe irritation of the respiratory tract with sore
         throat, coughing, shortness of breath and delayed lung edema. Causes
         chemical burns to the respiratory tract. Exposure to the mist and
         vapor may erode exposed teeth. Causes corrosive action on the mucous
         membranes.
    Chronic:
         Prolonged or repeated skin contact may cause dermatitis. Repeated
         exposure may cause erosion of teeth. May cause fetal effects.
         Laboratory experiments have resulted in mutagenic effects. Prolonged
         exposure may cause conjunctivitis, photosensitization, and possible
         blindness.

                   **** 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). SPEEDY ACTION IS CRITICAL!
    Skin:
         Get medical aid immediately. Immediately flush skin with plenty of
         soap and water for at least 15 minutes while removing contaminated
         clothing and shoes. Wash clothing before reuse. Destroy contaminated
         shoes.
    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. Give milk of
         magnesia.
    Inhalation:
         Get medical aid immediately. Remove from exposure to fresh air
         immediately. If breathing is difficult, give oxygen. 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:
         Do NOT use sodium bicarbonate in an attempt to neutralize the acid.
    Antidote:
         Do NOT use oils or ointments in eye.

                 **** 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. Water runoff can cause environmental damage. Dike
         and collect water used to fight fire. During a fire, irritating and
         highly toxic gases may be generated by thermal decomposition or
         combustion. Not fl>          of fumes in the air. Containers may explode when heated.
    Extinguishing Media:
         For large fires, use water spray, fog, or alcohol-resistant foam.
         Substance is nonflammable; use agent most appropriate to extinguish
         surrounding fire. Do NOT get water inside containers. Do NOT use
         straight streams of water. Most foams will react with the material
         and release corrosive/toxic gases. Cool containers with flooding
         quantities of water until well after fire is out. For small fires,
         use carbon dioxide (except for cyanides), dry chemical, dry sand,
         and alcohol-resistant foam.

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

    General Information: Use proper personal protective equipment as indicated
                         in Section 8.
    Spills/Leaks:
         Large spills may be neutralized with dilute alkaline solutions of
         soda ash, or lime. Avoid runoff into storm sewers and ditches which
         lead to waterways. Clean up spills immediately, observing
         precautions in the Protective Equipment section. Remove all sources
         of ignition. Provide ventilation. Do not get water inside
         containers. A vapor suppressing foam may be used to reduce vapors.
         Cover with dry earth, dry sand, or other non-combustible material
         followed with plastic sheet to minimize spreading and contact with
         water.

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

    Handling:
         Wash thoroughly after handling. Remove contaminated clothing and
         wash before reuse. Use only in a well-ventilated area. Contents may
         develop pressure upon prolonged storage. Do not breathe dust, vapor,
         mist, or gas. Do not get in eyes, on skin, or on clothing. Keep
         container tightly closed. Do not ingest or inhale. Discard
         contaminated shoes. Use caution when opening. Keep from contact with
         moist air and steam.
    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. Do not store in metal
         containers. Do not store near flammable or oxidizing substances
         (especially nitric acid or chlorates).

         **** 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 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 neoprene or polyvinyl chloride gloves to prevent
                      exposure.
            Clothing:
                      Wear appropriate protective clothing to prevent skin
                      exposure.
         Respirators:
                      A respiratory protection program that meets OSHA's 29
                      CFR :1910.134 and ANSI Z88.2 requirements or European
                      Standard EN 149 must be followed whenever workplace
