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

                               EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if
swallowed.Hygroscopic (absorbs moisture from the air).

Potential Health Effects
          May cause eye irritation.
          May cause skin irritation. May be metabolized to cyanide which in
          turn acts by inhibiting cytochrome oxidase impairing cellular
          Metabolism may release cyanide, which may result in headache,
          dizziness, weakness, collapse, unconsciousness and possible death.
          Ingestion may result in symptoms similar to cyanide poisoning which
          is characterized by asphyxiation. Large doses of cyanide may result
          in suddden loss of consciousness and  prompt death; small doses will
          prolong the above symptoms 1 to 2 hours.
          May cause respiratory tract irritation. May be metabolized to
          cyanide which in turns act by inhibiting cytochrome oxidase
          impairing cellular respiration.
          May be metabolized to cyanide which in turn acts by inhibiting
          cytochrome oxidase impairing cellular respiration. Chronic exposure
          to cyanide solutions may lead to the development of a "cyanide" rash,
          characterized by itching, and by macular, papular, and vesicular
          eruptions, and may be accompanied by secondary infections. Exposure
          to small amounts of cyanide compounds over long periods of time is
          reported to cause loss of appetite, headache, weakness, nausea,
          dizziness, and symptoms of irritation of the upper respiratory tract
          and eyes.

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

          In case of contact, immediately flush eyes with plenty of water for
          at least 15 minutes. Get medical aid.
          In case of contact, immediately flush skin with plenty of water.
          Remove contaminated clothing and shoes. Get medical aid. Wash
          clothing before reuse.
          If swallowed, do not induce vomiting unless directed to do so by
          medical personnel. Never give anything by mouth to an unconscious
          person. Get medical aid.
          If inhaled, remove to fresh air. If not breathing, give artificial
          respiration. If breathing is difficult, give oxygen. Get medical aid.
     Notes to Physician:
          Always have a cyanide antidote kit on hand when working with cyanide
          compounds. Get medical advice to use.

                  **** 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. Combustion
          by-products include oxides of nitrogen and hydrogen cyanide.
     Extinguishing Media:
          Use extinguishing media most appropriate for the surrounding fire.

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

     General Information: Use proper personal protective equipment as indicated
                          in Section 8.
          Clean up spills immediately, observing precautions in the Protective
          Equipment section. Sweep up, then place into a suitable container for
          disposal. Avoid generating dusty conditions. Provide ventilation.

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

          Wash thoroughly after handling. Remove contaminated clothing and
          wash before reuse. Minimize dust generation and accumulation. Avoid
          contact with eyes, skin, and clothing. Keep container tightly closed.
          Do not breathe dust. Use only with adequate ventilation.
          Store in a tightly closed container. Store in a cool, dry,
          well-ventilated area away from incompatible substances. Store
          protected from moisture.


     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.
