Safety & Handling
Sodium hydroxide is highly corrosive, and dilution releases heat. Add caustic slowly to water with mixing and cooling as needed. Wear chemical-resistant gloves, face and eye protection, and use compatible containers. Review the Safety Data Sheets before use and follow your site-specific handling procedure.
