Extinguishing Media Copper Sulfate does not burn nor will it support combustion. If stored with other combustible products use water, CO 2 or dry chemical. If dry heated above 600 C, SO 2 is evolved. If water is used it will solubalize the Copper Sulfate and care should be taken to keep such water out of streams or other water bodies. Incompatibility None know when product remains dry.
Product readily dissolves in water.
Solutions are mildly corrosive to steel. Iron and moisture should be avoided. Store in a dry area. With exposure to air it will oxidize and turn whitish. Hazardous Decomposition Products None at normal production temperatures and pressures.
