04 · Handling and storage
Storing and handling Demeton
Incompatible materials
Strong oxidizers, alkalis, water.

Reactivity
DEMETON may release sulfur oxides and phosphoric acid. Solvent carrier vapors may travel on ground to ignition source. Avoid strong oxidizers. Avoid mixtures with water or polar solvents, in which sulfur is lost to oxygen, air and light, which cause hydrolysis, alkaline mixtures and oxidizing agents. [EPA, 1998].
