                      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.

           Symptoms of Poisoning:  The compound does not cause any definite
      symptoms that would be diagnostic.  Poisoning is accompanied by
      hyperactivity followed by sedation (Bayleton 50 WP) (38c).

           SKIN CONTACT:  Wash skin immediately with soap and water (Bayleton
      50 WP) (38c).

           INGESTION:  Vomiting should be induced.  Administer water freely
      and induce vomiting by giving one dose (1/2 oz or 15 ml) of Syrup of
      Ipecac.  If vomiting does not occur within 10 to 20 minutes, administer
      second dose.  If Syrup of Ipecac is not available, induce vomiting by
      sticking finger down throat.  Repeat until vomit fluid is clear.  Never
      give anything by mouth to an unconscious person.  Professional medical
      assistance should be secured immediately (Bayleton 50 WP) (38c).

           INHALATION:  Remove to fresh air.  If not breathing, give
      artificial respiration, preferably mouth to mouth.  Get medical
      attention (Bayleton 50 WP) (38c).

           EYE CONTACT:  Wash with plenty of water for at least 15 minutes.
      Get medical attention (Bayleton 50 WP) (38c).

           NOTES TO PHYSICIAN:

           No specific antidote.  Treat symptomatically (Bayleton 50 WP)
      (38c).


                        VI.  FIRE AND EXPLOSION INFORMATION

           To be developed.


                                VII.  COMPATIBILITY

           To be developed.


                            VIII.  PROTECTIVE MEASURES

      STORAGE AND HANDLING:  Harmful if swallowed, inhaled, or absorbed
      through the skin.  Causes eye irritation.  Do not breathe dust or allow
      to get in eyes, on skin, or on clothing.  Wash hands, arms and face
      thoroughly with soap and warm water after use and before eating or
      smoking.  Wash all contaminated clothing with soap and hot water before
      reuse.  Do not contaminate feed or food items.  Keep out of reach of
      children (Bayleton 50 WP) (38c).
