A potential danger to those involved in manufacture, formulation and application of this fumigant insecticide in household, public health and agricultural uses. Used as an insecticide and as an anthelminthic for swine and dogs.
UN3018 Organophosphorus pesticides, liquid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials
50% hydrolysis is obtained in pure water in 25 minutes @ 70_x0003_°C and in 61.5 days @ 20C. A buffered solution yields 50% hydrolysis (37.5°C) in 301 minutes at pH 8, 462 minutes at pH 7, 620 minutes at pH 5.4. Hydrolysis yields no toxic residues. Incineration in a furnace equipped with an afterburner and alkaline scrubber is recommended as is alkaline hydrolysis followed by soil burial. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.

Contact with oxidizers may cause the release of phosphorous oxides. Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrideds and active metals. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides Corrosive to iron, mild steel, some forms of plastics, rubber, and coatings
