[Small spills/leaks]

Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the spilled amount. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
[Incompatibilities]

Incompatible with the following: Strong acids.
[Stability]

Stable.
[Decomposition]

Diuron, stable under normal conditions, decomposed on heating to 180 to 190 C giving dimethylamine and 3,4-dichlorophenylisocyanate. When heated to decomposition it emits highly toxic fumes of hydrogen chloride and nitrogen oxides.
[Combustion Products]

Highly toxic fumes are imminent Decomposes at 180 to 190C
