9. Wastewater Treatment

Know and follow disposal requirements regarding chemical handling and discharge, given in the form of a chemical "Material Safety Data Sheet" SDS. The working bath is alkaline and may require neutralization or wastewater treatment before the rinse water or working solution is discharged to the sewer. The working solution and the sediment accumulated in the tank may contain different components from the supplied chemicals. Before disposal, analyze the solution and sediment according to the relevant requirements.

10. Matters Needing Attention

When handling this chemical, carefully read, understand, and follow the product first aid and disposal methods listed on the Material Safety Data Sheet SDS. The working bath solution is alkaline and can cause skin and eye irritation. Do not get it in eyes, skin or clothing. Do not take internally. When handling, wear protective equipment such as masks, rubber gloves and protective clothing. In case of accidental contact, please follow the instructions on the corresponding material safety data sheet SDS. In case of personal injury, please go to a qualified hospital for emergency treatment and medical treatment.
