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.

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.
