                    **** 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.

                  **** 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. 
     Extinguishing Media: 
          Use agent most appropriate to extinguish fire. Use water spray, dry 
          chemical, carbon dioxide, or appropriate foam. 
 
                **** SECTION 6 - ACCIDENTAL RELEASE MEASURES **** 
 
     General Information: Use proper personal protective equipment as indicated 
                          in Section 8. 
     Spills/Leaks: 
          Clean up spills immediately, observing precautions in the Protective 
          Equipment section. Sweep up or absorb material, then place into a 
          suitable clean, dry, closed container for disposal. Avoid generating 
          dusty conditions. 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. Avoid contact with eyes, skin, and 
          clothing. Keep container tightly closed. Avoid ingestion and 
          inhalation. 
     Storage: 
          Keep container closed when not in use. 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: 
          Use adequate ventilation to keep airborne concentrations low.
