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
Copper salts and organic complexes (oxide, hydroxide, arsenite,
carbonate, chloride, oxalate, phosphate, silicate, sulfate, zinc
chromate, acetate, naphthenate, oleate, quinolinolate, and resinate).
These are commonly used as fungicides, either alone or in
combination with other agents. There are several dozen proprietary
LD50 values vary from 6 to 1000 mg/kg, depending mainly on the
solubility and degree of ionization of the copper compound.
Toxicity of copper-arsenite salts is due mainly to the arsenic
All of these salts irritate the skin and eyes and damage mucous
membranes. When ingested, they are powerfully emetic: the stomach
usually empties promptly and automatically in fully conscious
individuals. When retained and absorbed, toxic injury affects the
gastrointestinal lining, capillaries, brain, liver, kidney, and formed
elements of the blood. Copper salts are hemolytic.
Manifestations of poisoning include burning pain in the chest and
abdomen, intense nausea, vomiting, diarrhea, headche, sweating and
shock. Later, the liver is enlarged. Jaundice may reflect hemolysis
or liver damage or both. Anuria indicates kidney injury by copper
and/or free hemoglobin. Death may occur from convulsions, coma, or
hepatorenal failure. Elevated serum copper levels (maximum normal
level is 125 ug per 100 ml) indicate severity of poisoning (25).
SKIN CONTACT: Wash contaminated skin with copious amounts of
EYE CONTACT: Flush eyes with copious amounts of water (25).
NOTES TO PHYSICIAN:
Wash contaminated skin and flush eyes with copious amounts of
water. If copper salts have been ingested, lavage the stomach with
0.1% potassium ferrocyanide, then instill a suspension of egg white.
Intravenous fluids accelerate excretion. If signs of systemic
poisoning develop, give dimercaptrol (see Arsenical Pesticides for
dosage) or penicillamine, 0.5 gm orally four times daily, if patient
can retain oral medication. Shock may require blood transfusions and
pain may require morphine. Exchange transfusions may be considered in
severe poisonings. Renal failure may require protracted hemodialysis
VI. FIRE AND EXPLOSION INFORMATION
To be developed.
Compatible with most other pesticides (48).
VIII. PROTECTIVE MEASURES
STORAGE AND HANDLING: Normal storage free from excess moisture.
Flowable formulations store above freezing (56).
