           To be developed.


           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.


      BROOT 15GX Trimethacarb Insecticide is a carbamate insecticide, which
      is a cholinesterase inhibitor.  Overexposure to this substance through
      inhalation, eye or skin absorption, or ingestion may cause toxic signs
      and symptoms due to stimulation of the parasympathetic nervous system.
      These effects of overexposure are spontaneously and rapidly reversible.

      The onset of signs and symptoms of overexposure are extremely rapid,
      generally within minutes.  They consist of weakness, headache,
      sweating, blurred vision, giddiness, nausea, vomiting, diarrhea,
      salivation, lacrimation, pinpoint pupils, muscle twitching, dyspnea,
      and in severe cases, convulsions and respiratory failure (32d).

           INGESTION:  If Broot 15GX Trimethacarb Insecticide has been
      swallowed and the patient is conscious, induce vomiting.  Transport the
      patient to a physician or hospital immediately (32d).

           INHALATION:  In cases of overexposure, if breathing stops, start
      artificial respiration, establish an airway and provide oxygen (32d).

           EYE CONTACT:  Flush eyes with plenty of water for at least 15
      minutes.  See physician (32d).


      Specific treatment consists of parenteral atropine sulfate.  Caution
      should be maintained to prevent overatropinization.  Mild cases may be
      given 1 to 2 mg. intramuscularly every 10 minutes until full
      atropinization has been achieved and repeated thereafter whenever
      symptoms reappear.  Severe cases should be given 2 to 4 mg.
      intravenously every 10 minutes until fully atropinized, then
      intramuscularly every 30 to 60 minutes to maintain the effect for at
      least 12 hours.  Dosages for children should be appropriately reduced.
      Complete recovery from overexposure is to be expected within 24 hours.

      Narcotics and other sedatives should not be used.  Further, drugs like
      2-PAM (pyridine-2-aldoxime methiodide) are not recommended unless
      organophosphate intoxication is also suggested.  To aid in confirmation
      of a diagnosis, urine samples should be obtained wtihin 24 hours of
      exposure and immediately frozen.  Analyses will be arranged by Union
      Carbide Agricultural Products Company, Inc.

      Consultation on therapy can be obtained at all hours by calling the
      Union Carbide emergency number:  (304) 744-3487 (32d).

                        VI.  FIRE AND EXPLOSION INFORMATION

      FLASH POINT:  Solid - not applicable.

      GENERAL:  Wear protective clothing and use self-contained breathing
      apparatus.  Monitor any water run-off and dike surrounding area.  After
      fire fighting operations, remove contaminated clothing and shower
      thoroughly.  Products of combustion and decomposition can be noxious.
      Stay out of smoke (32d).

      EXTINGUISHER TYPE:  Use foam if available.  If possible, avoid water
      because it can spread contamination.  Dry chemical or carbon dioxide
      are preferable on small fires (32d).

                                VII.  COMPATIBILITY

           Avoid contamination with acids and alkalis (32d).

                            VIII.  PROTECTIVE MEASURES

           To be developed.

                       IX.  PROCEDURES FOR SPILLS AND LEAKS

                                  (800) 424-9300

      Steps to be taken if material is released of spilled:

           Sweep or shovel spilled material into approved waste containers
      avoiding dusting.  Wear protective clothing and equipment.

      Waste disposal method:

           Dispose in an approved incinerator or landfill following all
      applicable federal, state, and local regulations (32d).
