                  **** SECTION 3 - HAZARDS IDENTIFICATION **** 
 
                               EMERGENCY OVERVIEW 
Irritating to eyes, respiratory system and skin.Stench. 
 
Potential Health Effects 
     Eye: 
          Causes eye irritation.  May cause chemical conjunctivitis and 
          corneal damage. 
     Skin: 
          Causes skin irritation. May cause cyanosis of the extremities. 
     Ingestion: 
          May cause gastrointestinal irritation with nausea, vomiting and 
          diarrhea. 
     Inhalation: 
          Causes respiratory tract irritation. Can produce delayed pulmonary 
          edema. Inhalation at high concentrations may cause CNS depression and 
          asphixiation. 
     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. Flush skin with plenty of 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 and move 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. 
 
                  **** 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. Use water 
          spray to keep fire-exposed containers cool. Combustible liquid. 
          Vapors may be heavier than air.  They can spread along the ground and 
          collect in low or confined areas. Containers may explode when heated. 
     Extinguishing Media: 
          Use water spray to cool fire-exposed containers. 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: 
          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. Remove all 
          sources of ignition. Use a spark-proof tool. Provide ventilation. 
 
                   **** SECTION 7 - HANDLING and STORAGE **** 
 
     Handling: 
          Wash thoroughly after handling. Remove contaminated clothing and 
          wash before reuse. Use only in a well-ventilated area. Avoid contact 
          with eyes, skin, and clothing. Empty containers retain product 
          residue, (liquid and/or vapor), and can be dangerous. Keep container 
          tightly closed. Keep away from heat, sparks and flame. Avoid 
          ingestion and inhalation. Do not pressurize, cut, weld, braze, 
          solder, drill, grind, or expose empty containers to heat, sparks or 
          open flames. 
     Storage: 
          Keep away from heat, sparks, and flame. Keep away from sources of 
          ignition. 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 general or 
          local explosion-proof ventilation to keep airborne levels to 
          acceptable levels.
