Organophosphates, such as TRIBUTOXYETHYL PHOSPHATE, 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. This material may react with oxidizers. (NTP, 1992).
