04 · Handling and storage

Storing and handling Dimefox

Storage conditions

... Must be stored in its sealed original containers, in well-aired, fresh & dry storehouses or in shaded & possibly well-aired places. It is recommended that the product's temperature ... not exceed 25-30 °C, & keep ... away from sources of heat, free flames or spark-generating equipment. Containers must be stacked in such a way as to permit free circulation of air ... at bottom & inside of piles. Storage areas must be located at suitable distance from inhabited buildings, animal shelters, & food stores; moreover, they must be inaccessible to unauthorized persons, children, & domestic animals. /Prothoate/

Reactivity

Highly toxic fumes are given off upon decomposition of DIMEFOX with heat. Container may explode in heat of fire. Decomposes rapidly in the presence of chlorine. Oxidizes slowly in strong oxidizing agents. [EPA, 1998]. Organophosphates 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.
