Red section

Yellow section

Blue section

White section

The "use no water" symbol is found in the white section of the NFPA 704 HazMat diamond. This section specifically provides information on special hazards associated with a material, including whether water is an acceptable method for firefighting or if it should be avoided altogether. The symbol clearly indicates to first responders that the application of water could exacerbate the situation, especially in cases where water may react violently with the substance or spread the fire.

The inclusion of this symbol in the white section underscores its critical importance in informing firefighting strategies and ensuring the safety of both personnel and the surrounding environment during a hazardous materials incident. Understanding this aspect of the NFPA 704 system is vital for quick and effective response to potential hazards in firefighting operations.
