04 · Handling and storage
Storing and handling Phosacetim
Reactivity
Organothiophosphates, such as PHOSACETIM, 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.
