The white diamond on NFPA 704 is used to identify what?

• A. Special properties of a hazmat.
• B. Health hazards
• C. Flammability hazards
• D. Reactivity hazards

Answer: (A)

The white section in NFPA 704 is used for special properties of the hazmat. While the blue, red, and yellow sectors indicate health hazards, flammability, and reactivity, respectively, the white area flags additional, nonstandard hazards that require extra precautions—such as water reactivity (often shown with a W with a slash) or other notes like oxidizers, corrosive properties, or radioactive characteristics. This is why the white diamond tells you about special conditions that aren’t captured by the three main hazard types.
