          blood pressure, rapid pulse and visual disturbances.
     Inhalation:
          May cause respiratory tract irritation. May be harmful if inhaled.
     Chronic:
          Possible risk of irreversible effects.

                    **** SECTION 4 - FIRST AID MEASURES ****

          pressure-demand, MSHA/NIOSH (approved or equivalent), and full
          protective gear. Dusts at sufficient concentrations can form
          explosive mixtures with air.
     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.

                   **** SECTION 7 - HANDLING and STORAGE ****

     Handling:
          Use with adequate ventilation. Minimize dust generation and
          accumulation. Avoid breathing dust, vapor, mist, or gas. Avoid
          contact with skin and eyes. Take precautionary measures against
          static discharges.
     Storage:
