                      V.  EMERGENCY AND FIRST AID PROCEDURES

           The chemical information provided below has been condensed
      from original source documents, primarily from "Recognition and
      Management of Pesticide Poisonings", 3rd ed. by Donald P.  Morgan,
      which have been footnoted.  This information has been provided in
      this form for your convenience and general guidance only.  In
      specific cases, further consultation and reference may be required
      and is recommended.  This information is not intended as a sub-
      stitute for a more exhaustive review of the literature nor for the
      judgement of a physician or other trained professional.

           If poisoning is suspected, do not wait for symptoms to develop.
      Contact a physician, the nearest hospital, or the nearest Poison
      Control Center.

           SKIN CONTACT:  If on skin, wash thoroughly (21f).

           INGESTION:  No specific antidote is known.  Administer charcoal
      to absorb any of the product taken internally.  Apply gastric lavage
      with much water.  Administer lavage in small amounts.  After lavage,
      saline laxative (Glauber's salt) can be given (21f).

           EYE CONTACT:   If in eyes, flush with water and obtain prompt
      medical attention (21f).

      NOTES TO PHYSICIAN:

           No specific antidote is known.  Administer charcoal to absorb any
      of the product taken internally.  Apply gastric lavage with much water.
      Administer lavage in small amounts.  After lavage, saline laxative
      (Glauber's salt) can be given (21f).

                        VI.  FIRE AND EXPLOSION INFORMATION

           To be developed.

                                VII.  COMPATIBILITY

           Compatible with wettable powder formulations of other fungicides
      and insecticides.  Do not mix with oil.  Do not add spreader or sticker
      (48).

                            VIII.  PROTECTIVE MEASURES

      STORAGE AND HANDLING:  Keep out of the reach of children.  Harmful if
      swallowed or absorbed through the skin.  Do not breathe dust or spray
      mist.  Do not allow contact with eyes or skin.  Avoid contamination of
      feed and foodstuffs.  Avoid contamination of water containing marine
      fish or shellfish or that may be used for domestic purposes (21f).

      PROTECTIVE CLOTHING:   Wear clean protective clothing and bathe after
      each exposure (21f).  Wear goggles or face shield when handling (56).
