                               EMERGENCY OVERVIEW 
The toxicological properties of this material have not been fully 
investigated. 
 
Potential Health Effects 
     Eye: 
          May cause eye irritation. 
     Skin: 
          May cause skin irritation. 
     Ingestion: 
          May cause irritation of the digestive tract. The toxicological 
          properties of this substance have not been fully investigated. 
     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: 
          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. 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: 
 
                  **** 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. This 
          material in sufficient quantity and reduced particle size is capable 
          of creating a dust explosion. 
     Extinguishing Media: 
          Use water spray, dry chemical, carbon dioxide, or chemical foam. 
 
                **** SECTION 6 - ACCIDENTAL RELEASE MEASURES **** 
 
     General Information: Use proper personal protective equipment as indicated 
                          in Section 8. 
     Spills/Leaks: 
          Vacuum or sweep up material and place into a suitable disposal 
          container. Clean up spills immediately, observing precautions in the 
          Protective Equipment section. 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 breathing dust, vapor, mist, or 
          gas. Avoid contact with eyes, skin, and clothing. Keep container 
          tightly closed. Avoid ingestion and inhalation. 
     Storage: 
          Store in a cool, dry place. Store in a tightly closed container. 
 
          **** 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.

                       protection regulations in 29 CFR 1910.133 or European 
                       Standard EN166. 
                 Skin: 
                       Wear appropriate protective gloves to prevent skin 
                       exposure. 
             Clothing: 
                       Wear appropriate protective clothing to prevent skin 
                       exposure. 
          Respirators: 
                       Follow the OSHA respirator regulations found in 29 
                       CFR 1910.134 or European Standard EN 149. Use a 
                       NIOSH/MSHA or European Standard EN 149 approved 
                       respirator if exposure limits are exceeded or if
