Chemical Properties
Fosthietan is a pale yellow oil. It has a
mercaptan-like odor.
Uses
Nematocide; insecticide.
General Description
Pale yellow liquid with a mercaptan-like odor. Used as a nematocide and insecticide. Not registered as a pesticide in the U.S.
Reactivity Profile
Organophosphates, such as FOSTHIETAN, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Health Hazard
FOSTHIETAN is a liquid organophosphorus insecticide. Organic phosphorus insecticides are absorbed by the skin, as well as by the respiratory and gastrointestinal tracts.
Fire Hazard
When heated to decomposition, FOSTHIETAN emits very toxic fumes of nitrogen oxides, phosphorus oxides and sulfur oxides. FOSTHIETAN is a liquid organophosphorus insecticide. Container may explode in heat of fire.
Potential Exposure
Fosthietan is used as a nematocide
and insecticide. Not currently registered as a pesticide in
the U.S.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Speed in removing material from skin
is of extreme importance. Shampoo hair promptly if con taminated. Seek medical attention immediately. If this
chemical has been inhaled, remove from exposure, begin
rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medi cal attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit.
Remove and isolate contaminated clothing and shoes at the
site. Keep victim quiet and maintain normal body tempera ture. Effects may be delayed; keep victim under
observation.
Shipping
UN3018 Organophosphorus pesticides, liquid,
toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine,
bromine, fluorine, etc.); contact may cause fires or explo sions. Keep away from alkaline materials, strong bases,
strong acids, oxoacids, epoxides. Strong oxidizers may cause
release of toxic phosphorus oxides. Organophosphates, in the
presence of strong reducing agents such as hydrides, may
form highly toxic and flammable phosphine gas.

storage
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area away from alkaline material. Where possible, automatically pump liquid from drums or other storagecontainers to process containers.
