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
f this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelyFosthietan 1363with soap and water. Speed in removing material from skinis of extreme importance. Shampoo hair promptly if contaminated. Seek medical attention immediately. If this chemicalhas been inhaled, remove from exposure, begin rescuebreathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart actionhas stopped. Transfer promptly to a medical facility. Whenthis chemical has been swallowed, get medical attention.Give large quantities of water and induce vomiting. Do notmake an unconscious person vomit. Remove and isolatecontaminated clothing and shoes at the site. Keep victimquiet and maintain normal body temperature. Effects may bedelayed; keep victim under observation.
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.
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.
Waste Disposal
In accordance with 40CFR 165 recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by follow ing package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
