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
SKIN CONTACT: If on skin, wash thoroughly (21f).
INGESTION: No specific antidote is known. Administer charcoal
to absorb any of the product taken internally. Apply gastric lavage
with much water. Administer lavage in small amounts. After lavage,
saline laxative (Glauber's salt) can be given (21f).
EYE CONTACT: If in eyes, flush with water and obtain prompt
medical attention (21f).
NOTES TO PHYSICIAN:
No specific antidote is known. Administer charcoal to absorb any
of the product taken internally. Apply gastric lavage with much water.
Administer lavage in small amounts. After lavage, saline laxative
(Glauber's salt) can be given (21f).
VI. FIRE AND EXPLOSION INFORMATION
To be developed.
Compatible with wettable powder formulations of other fungicides
and insecticides. Do not mix with oil. Do not add spreader or sticker
VIII. PROTECTIVE MEASURES
STORAGE AND HANDLING: Keep out of the reach of children. Harmful if
swallowed or absorbed through the skin. Do not breathe dust or spray
mist. Do not allow contact with eyes or skin. Avoid contamination of
feed and foodstuffs. Avoid contamination of water containing marine
fish or shellfish or that may be used for domestic purposes (21f).
PROTECTIVE CLOTHING: Wear clean protective clothing and bathe after
