In NFPA 704, which color indicates special hazards?

Explanation:
The white section of the NFPA 704 diamond is used for special hazards. While blue, red, and yellow give health, flammability, and reactivity ratings, the white area flags additional hazards that don’t fit into those three categories—such as oxidizers or water-reactive materials—and may display letters or symbols to indicate those conditions. So, for special hazards, the color to look for is white.
