In the NFPA 704 system, the "No Water" symbol is represented by a white circle with a diagonal line through it, which typically appears in the blue section of the diamond. This symbol indicates that water should not be used on the material in question during firefighting efforts. You can find this symbol on the NFPA 704 placard, often displayed on hazardous materials to inform first responders of the appropriate safety measures.
