           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.


           Thiram and metallo bis dithiocarbamates - Itching, redness, and
      eczematoid DERMATITIS have resulted when predisposed individuals have
      come into contact with these agents.  Inhaled sprays and dusts have
      caused NASAL STUFFINESS, hoarseness, cough, and, rarely, pneumonitis.
      Repeated contact may produce sensitization.  Ingestion of large amounts
      may produce nausea, VOMITING, and DIARRHEA.  HYPOTHERMIA and ataxia are
      characteristic of poisoning.  Muscle WEAKNESS and/or ascending
      paralysis may progress to respiratory paralysis if absorbed dosages are
      equivalent to those tested in experimental animals.
           The reaction to beverage alcohol that may follow exceptional
      absorption of thiram and metallo bis dithiocarbamates is characterized
      by FLUSHING, HEADACHE, SWEATING, warm sensations, weakness, nasal
      congestion, labored breathing, tightness in the chest, tachycardia,
      palpitation, and hypotension.  Extreme dosages may result in shock,
      convulsions, respiratory depression, and/or unconsciousness.  Reactions
      are not likely to occur unless the absorbed dose is extraordinary (25).

           SKIN CONTACT:  Wash contaminating chemical from skin and hair with
      soap and water (25).

           INGESTION:  If vigorous emesis has not already occurred and
      victim is fully alert, give Syrup of Ipecac, followed by 1-2 glasses of
      water to induce vomiting (adults 12 years and older:  30 ml; children
      under 12:  15 ml) (25).

           EYE CONTACT:  Flush contaminant from eyes with fresh water for
      10-15 minutes (25).


      1.   If THIRAM or METALLO DITHIOCARBAMATE compounds have been ingested:
           A.  If vigorous emesis has not already occurred and victim is
               fully alert, give SYRUP OF IPECAC, followed by 1-2 glasses of
               water to induce vomiting (adults, 12 years and older:  30 ml;
               children under 12:  15 ml).
               CAUTION:   OBSERVE victim closely AFTER administering IPECAC.
                          If CONSCIOUSNESS level declines or vomiting has not
                          occurred in 15 minutes, empty the stomach by
                          INTUBATION, ASPIRATION, and LAVAGE.
           B.  IF consciousness level or respiration is DEPRESSED, empty the
               stomach by INTUBATION, ASPIRATION, and LAVAGE, using all
               available means to avoid aspiration of vomitus:  left lateral
               Trendelenburg position, frequent aspiration of the pharynx
               and, in unconscious victims, tracheal intubation (using a
               cuffed tube) prior to gastric intubation.
               After aspiration of the stomach and washing with isotonic
               saline or sodium bicarbonate, instill 30-50 gm of ACTIVATED
               CHARCOAL in 3-4 ounces of water through the stomach tube to
               limit absorption of remaining toxicant.
           C.  If the irritant properties of the toxicant fail to produce a
               bowel movement in 4 hours, administer SODIUM or MAGNESIUM
               SULFATE as a cathartic:  0.25 gm/kg body weight in 1-6 ounces
               of water.
           D.  Administer glucose-containing fluids intravenously to
               accelerate excretion of toxicant.
           E.  For adults and children over 12 years, inject 1.0 gm ASCORBIC
               ACID (Vitamin C) intravenously at a rate not exceeding 0.2
               gm/minute.  For children under 12, give 10-20 mg/kg body
               weight.  As a hydrogen-donor, ascorbic acid may have
               significant antidotal action against absorbed, but unreacted,
               dithiocarbamate compounds.
           F.  The victim must AVOID consumption of any ALCOHOLIC beverage
               for 3 weeks.  Gastrointestinal absorption of these substances
               is slow, and the enzyme inhibition which they cause is slowly
      2.   Management of a reaction to ETHANOL, following absorption of a
           A.  Administer 100% OXYGEN as long as the reaction continues.
               Oxygen usually gives substantial relief from the distressing
               symptoms of vasodilation and hypotension.
               CAUTION:   If respiration is depressed, administer oxygen by
                          an intermittent positive pressure breathing device
                          and observe the victim closely to maintain
                          pulmonary ventilation mechanically in case of
           B.  Gastric evacuation, charcoal administration, catharsis,
               intravenous fluids, and ascorbic acid administration (1
               A,B,C,D, and E) may be appropriate, depending on the amount of
               dithiocarbamate absorbed, the time interval between exposure
               and treatment, and the severity of symptoms.
           C.  If the victim has suffered from arteriosclerosis, myocardial
               insufficiency, diabetes, neuropathy, cirrhosis, or other
               severe chronic disease, OBSERVE him CAREFULLY for 48 hours to
               insure that complications (especially myocardial infarction,
               toxic, psychosis, and neuropathy) are treated promptly.
      3.   If an ETHYLENE BIS DITHIOCARBAMATE, or (mono) thiocarbamate have
           been ingested:
           A.  Give SYRUP OF IPECAC, followed by 1-2 glasses of water, to
               induce vomiting (adults:  30 ml; children under 12 years:  15
               ml).  Following emesis, administer 30-50 gm ACTIVATED CHARCOAL
               to bind toxicant remaining in the gut.
           B.  Follow charcoal with SODIUM or MAGNESIUM SULFATE, 0.25 gm/kg,
               to remove toxicant from the gut by catharsis (25).
