          this substance have not been fully investigated. Toxic if inhaled. 
          Can produce delayed pulmonary edema. 
     Chronic: 
          Effects may be delayed. 
 
                    **** SECTION 4 - FIRST AID MEASURES **** 
 
     Eyes: 
          Immediately 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 immediately. Immediately flush skin with plenty of 
          water for at least 15 minutes while removing contaminated clothing 
          and shoes. Wash clothing before reuse.

     Inhalation: 
          Get medical aid immediately. Remove from exposure and move to fresh 
          air immediately. If not breathing, give artificial respiration. If 
          breathing is difficult, give oxygen. Do NOT use mouth-to-mouth 
          resuscitation. 
     Notes to Physician: 
          Treat symptomatically and supportively. 
 
                  **** 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: 
          In case of fire, use water, dry chemical, chemical foam, or 
          alcohol-resistant foam. Use agent most appropriate to extinguish 
          fire. 
 
                **** 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. Provide 
          ventilation. 
 
                   **** SECTION 7 - HANDLING and STORAGE ****

          Wash thoroughly after handling. Remove contaminated clothing and 
          wash before reuse. Use only in a well-ventilated area. Do not get in 
          eyes, on skin, or on clothing. Keep container tightly closed. Do not 
          ingest or inhale. Discard contaminated shoes. 
     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: 
          Facilities storing or utilizing this material should be equipped
