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
FREQUENT SYMPTOMS AND SIGNS OF POISONING
All of these salts (including copper hydroxide) 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 in the chest and
abdomen, intense nausea, vomiting, diarrhea, headache, 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 (25).
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 or penicillamine, 0.5 mg 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 (25).
VI. FIRE AND EXPLOSION INFORMATION
To be developed.
Compatible with most other pesticides. Some formulations should
not be mixed with water. Check label (48).
VIII. PROTECTIVE MEASURES
To be developed.
