spills. Do not wash away spilled solution. Collect and treat solution by reacting with soda ash to form an insoluble copper carbonate solid that can be scooped up.

•  • Waste Disposal: Comply with Federal, State and local regulations on waste

disposal. React solution with soda ash to form an insoluble copper carbonate solid that can be disposed of in an approved landfill.
