                  **** SECTION 3 - HAZARDS IDENTIFICATION **** 
 
                               EMERGENCY OVERVIEW 
Risk of serious damage to eyes. Contact with combustible material 
may cause fire.The toxicological properties of this material have 
not been fully investigated.Hygroscopic (absorbs moisture from the 
air). 
 
Potential Health Effects 
     Eye: 
          May cause eye irritation.  Dust may cause mechanical irritation. 
          The toxicological properties of this material have not been fully 
          investigated. 
     Skin: 
          May cause skin irritation. The toxicological properties of this 
          material have not been fully investigated. 
     Ingestion: 
          May cause methemoglobinemia, cyanosis (bluish discoloration of skin 
          due to deficient oxygenation of the blood), convulsions, and death. 
          May cause digestive tract disturbances. The toxicological properties 
          of this substance have not been fully investigated. Expected to be a 
          low ingestion hazard. Methemoglobinemia is characterized by 
          dizziness, drowsiness, headache, shortness of breath, cyanosis 
          (bluish discoloration of skin due to deficient oxygenation of the 
          blood), rapid heart rate and chocolate-brown colored blood. 
     Inhalation: 
          May cause respiratory tract irritation. 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 water for at least 15 
          minutes while removing contaminated clothing and shoes. Wash clothing 
          before reuse. 
     Ingestion: 
          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. Wash mouth out with water. 
     Inhalation: 
          Remove from exposure and move to fresh air immediately. If not 
          breathing, give artificial respiration. If breathing is difficult, 
          give oxygen. Get medical aid. 
     Notes to Physician: 
     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 other material may 
          cause fire. During a fire, irritating and highly toxic gases may be 
          generated by thermal decomposition or combustion. 
     Extinguishing Media: 
          Use water only! Use water spray, dry chemical, carbon dioxide, or 
          chemical foam. Contact professional fire-fighters immediately. 
 
                **** 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. 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. Use only in a well-ventilated area. 
          Use with adequate ventilation. Minimize dust generation and 
          accumulation. Avoid breathing dust, vapor, mist, or gas. Avoid 
          contact with eyes, skin, and clothing. Avoid contact with skin and 
          eyes. Keep container tightly closed. Avoid contact with clothing and 
          other combustible materials. Avoid ingestion and inhalation. Use only 
          in a chemical fume hood. 
     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.
