Incompatibilities

Decomposed by air, light, alkaline media, and temperatures .175℃. May react violently with strong oxidizers, bromine, 90% hydrogen peroxide, phos- phorus trichloride, silver powders or dust. Incompatible with silver compounds. Mixture with some silver compounds forms explosive salts of silver oxalate.

Waste Disposal

Incineration would be an effective disposal procedure where permitted. If an efficient incinerator is not available, the product should be mixed with large amounts of combustible material and contact with the smoke should be avoided. In accordance with 40CFR165. Follow recommendations for the disposal of pesticides and pesticide containers . Bury in noncrop land away from water. It would be better to mix the prod- uct with lime. Incineration would be an effective disposal procedure where permitted. If an efficient incinerator is not available, the product should be mixed with large amount of combustible material. Recommendable methods: Hydrolysis, landfill, incineration, and open burning. Not recommendable method: Discharge to sewer. Mix with saw- dust and burn at a remote place .
