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

                              EMERGENCY OVERVIEW
Irritating to eyes. Contact with combustible material may cause
fire.The toxicological properties of this material have not been
fully investigated.

Potential Health Effects
    Eye:
         Causes eye irritation.
    Skin:
         Causes skin irritation. If absorbed, causes symptoms similar to
         those of ingestion.
    Ingestion:
         Causes gastrointestinal irritation with nausea, vomiting and
         diarrhea. May cause methemoglobinemia, cyanosis, convulsions, and
         death. The toxicological properties of this substance have not been
         fully investigated. Methemoglobinemia is characterized by dizziness,
         drowsiness, headache, breath shortness, cyanosis with bluish skin,
         rapid heart rate and chocolate-brown colored blood.
    Inhalation:
         Causes respiratory tract irritation. May cause effects similar to
         those described for ingestion. The toxicological properties of this
         substance have not been fully investigated.
    Chronic:
         No information found.

                   **** 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.
    Skin:
         Get medical aid. Flush skin with plenty of soap and water for at
         least 15 minutes while removing contaminated clothing and shoes. Wash
         clothing before reuse.
    Ingestion:
         Never give anything by mouth to an unconscious person. Get medical
         aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
         drink 2-4 cupfuls of milk or water.
    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 and supportively.
    Antidote:
         None reported.

                 **** 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. Strong oxidizer. Contact with combustible materials
         may cause a fire. During a fire, irritating and highly toxic gases
         may be generated by thermal decomposition or combustion. Use water
         with caution and in flooding amounts.
    Extinguishing Media:
         Use water spray to cool fire-exposed containers. Use water only!
         Contact professional fire-fighters immediately.

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

    General Information: Use proper personal protective equipment as indicated
                         in Section 8.
    Spills/Leaks:
         Vacuum or sweep up material and place into a suitable disposal
         container. Clean up spills immediately, observing precautions in the
         Protective Equipment section. Avoid generating dusty conditions.
         Remove all sources of ignition. Provide ventilation.

                  **** 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. Material is heat, shock and/or friction
         sensitive. Use care in handling and storage. Avoid contact with
         eyes, skin, and clothing. Keep container tightly closed. Avoid
         contact with clothing and other combustible materials. Avoid
         ingestion and inhalation. Wash clothing before reuse.
    Storage:
         Keep away from heat, sparks, and flame. Do not store near
         combustible materials. Store in a tightly closed container. Store in
         a cool, dry, well-ventilated area away from incompatible substances.

         **** 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 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:
                      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
                      conditions warrant a respirator's use. 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.
